This is a work in progress & it will never be finished (10-25-04).
Quote:
The only precise way to choose a PS is to add up the maximum current (amperage)
draw for each individual rail and then provide at least an additional 20% for overhead.
All PS calculators use averages, they are not precise.
A 1000Watt PS is useless if that wattage is delivered on the wrong rail(s)!
All of the above are very good PSU's & are recommended.
My personal "BEST BANG for the BUCK" choices are:
$38: XCilo 450W (Lowend to Midrange)
$52: XClio GoodPower 500W (Midrange)
$80: Antec TruePower Trio 550W (Highend to Midrange SLI/CF)
$103: Antec TruePower Trio 650W (8800GTS SLI)
$149: SilverStone Olympia OP750 750W (8800GTX SLI)
$335: SILVERSTONE Olympia OP1000 1000W (R600 CrossFire)
If you require extreme quiet & would like a modular PSU, then the Corsairs were made for you!
Voltages & Amperage: Only the +3.3V, +5V, +5VSB & +12V are used by modern computers. Spec is usually +/- 5%. When the original ATX spec was written the +3.3V & +5V were far more stressed by heavy usage demands than they are in today's computers. Almost any high quality ATX spec PS of 300Watts or more can supply far more +3.3V & +5V amperage than today's computers require. Today's computers, especially the AMD A64's and the latest Intel's stress the +12V rail the most, requiring far more amperage than was originally called for in the original ATX spec for the +12V rail. Video cards can be the biggest +12V resource hogs!
Wattage: Voltage times Amperage equals Wattage. Wattage is the ability to do work; it can be converted into Horse Power. A PS's wattage rating is the total combined wattage output of all the rails combined. Older ATX designs created most of their wattage in the +3.3 & +5V rails, creating very little on the +12V rail. Newer ATX12V & ATX12 V2.0 designs are creating ever more wattage on the +12V rail, to meet the needs of today's & tomorrow's computers.
To see why total wattage should never be used to select a power supply, but that the properly allocated wattage is very important in selecting the proper PS, please click on the following link to the ONLY "Power Supply Calculator" that I can & DO RECOMMEND, provided by & constantly updated by "mnemonik23": http://www.extreme.outervision.com/
PC P&C Power Supply Selector: http://www.pcpowercooling.com/produc...lies/selector/
Multipul +12V Rails: Most PS's today supply all of their +12V amperage through one rail, just like almost every PS manufacturer supplies their +3.3V and +5V through one rail each. However some forward thinking manufacture's are supplying their +12V amperage through more than one rail, the most common today for PC's is to use two +12V rails or dual rails. The new ATX12 V2.0 spec. also requires dual (or more) +12V rails. This has both advantages & disadvantages.
Why more than one +12V rail? Electrical isolation for noise and improved load/voltage regulation. Some devices, usually electromechanical ones having motors, produce noise spikes & voltage fluxuations, these can include pumps, compressors, fans, drives, lights (when turned on & off) and probably TEC's & Peltiers. By putting these "noisy" devices, that often turn on & off, or at least often change their power (amperage) demands, on a separate rail we isolate them from the MoBo, CPU, Video Card(s) and the other electronic components that are sensitive to noise & sudden changes in voltage. This can be a good thing! ATX12 V2.0 is the future.
Additional Dual Rail Information: http://forums.extremeoverclocking.co...62#post1371562
Hold Up Time: Measured in milliseconds (ms) is how long the PS will continue to supply in spec voltage & amperage, once the AC input voltage is removed. The longer the hold up time generally the higher the quality of the PS. Hold up time gives the time necessary for an Uninterruptible Power Supply (UPS) to switch to batteries and allow uninterrupted operation of the computer.
Efficiency and Temperature: There are no electronic devices that are 100% efficient & PS's are no exception. Typically PS's operate between 60% and 85% efficiency. The more efficient the PS, the less power that is lost as heat and the lower the cooling requirements. Newer PSU's meeting the ATX12V 2.xx specs have efficiency ratings from 70% to as high as 85%. The "80%+" certification requires 80% or higher efficiency.
Reading and Adjusting Voltages: BIOS and software such as Motherboard Monitor 5 (MM5) can not be fully trusted to give accurate voltage readings and since many of today's better PS's allow the user to easily adjust their voltages, it is very important that a voltmeter/multimeter be used to measure these voltages correctly.

PFC: Power Factor Correction: This has always been important for large scale commerical applications,
now it is something that the home & small office user can also consider,
especially if you are going to be operating outside of north america.
Required by law in the EU, it is really not a "big deal" for the home & small office user in north america.
Here is a good explination of PFC: http://www.rojakpot.com/default.aspx...var1=81&var2=0

new egg: I started using new egg as the primary reference source for several reasons including their popularity, broad selection, low prices & format. There is also the fact that I'm basically lazy & using new egg made this much easier! I am now trying to link the factory specs & use Google/Froogle for lowest pricing.
Other PS's: I am not perfect or all knowledgeable, it is highly probable that I have made errors of omission, please forgive me as I have done more or less the best that I could given the restraints of the real world. I am sure that there are other PS's that deserve to be recommended and with any major price changes my recommendations might have been different.
I update this guide as often as possible, already (11-4-04) as a result of suggestions by knowledgeable EOCF members 4 additional PS's have been added to the recommended list. Please add your experiences, comments & recommendations to this thread. They will be appericated.
APC UPS: American Power Conversion (APC) http://www.apcc.com makers of IMO the world's finest Uninterruptible Power Supplies (UPS), check them out, I promise that you will be glad you did.

Use 2 or more PS's: It is often better & cheaper to use more than one PS to power your computer. There are two methods of doing this, the first is simple & safe, the second requires the skills of an electronics technician and if performed improperly could damage your system, and so we will concentrate on the safe & simple method.
Use a second PS to power your lights & fans and maybe your HDD's, FDD's & OD's. Allowing your main PS to concentrate on your MoBo, CPU & Video Card(s). As your lights, fans & various drives are electrically isolated from your MoBo, this is safe & simple, allowing you to use as many PS's as required, to power all of the eye candy imaginable. Turn your Fans & Drives "ON" first & turn them "OFF" last.
To be recommended to power a modern system the power supply must meet the following criteria:
(1) It must meet all usual ATX, AMD, Intel & UL standards for USA operation,
(2) It must have been manufactured by a well known reputable company, known to offer products of very high quality, their products having been used, tested, reviewed & recommended by many experienced & knowledgeable users, and
(3) It must supply a minimum of 26A on the +12V rail(s), as this is critical for today's computers.
To be recommended as a "BEST BANG for the BUCK", in addition to meeting all of the above criteria,
the PS must clearly supply more +12V amperage for less money, than its competitors.
Cheap, but Good Power Supplies! http://forums.extremeoverclocking.co...&postcount=197
To be recommended for "Premium Choices", in addition to meeting to meeting the basic criteria,
the PS must be of exceptional quality, literally being one of the very best in the world.
Many of these also offer special features not usually found on lesser PS's,
such as tighter load/voltage regulation, extreme power, silent operation or user adjustable voltages.
To be recommended for "Professional Choices", in addition to meeting to meeting the basic criteria,
the PS must have been designed & built to the exacting standards required to
power professional workstations & servers, where failure is not an option.
These PSU's must be "The Best of the Best of the Best"!

All PSU's recommended for highend systems need to be Single +12V Rail PSU's. This has now become necessary for several reasons: PSU manufactures are now assigning the rails on their multi-rail (3 or more +12V rails) PSU's in whatever fashion pleases them. Motherboard manufacturers are now requiring additional power connectors, beyond the standard ATX & P4/EPS connectors. Sometimes the interaction of these unique rail assignments & additional power connectors results in mobo/PSU incompatibility. All of these problems are of course caused by the ever higher power demands of ever more powerful GPU's. Most Dual +12V Rail PSU's are not effected as one rail "should always" be used exclusively to power the CPU via the P4/EPS connector, however Dual Rail PSU's that follow the specs can not power highend SLI systems. Therefore all PSU's recommended for highend systems now need to be Single +12V Rail PSU's. Please note that the Seasonic built Corsairs & Antecs (HE & Trio) are, regardless of advertising, Single +12V Rail PSU's, in that there is no per-rail current limiting, meaning that any +12V rail can pull whatever +12V amperage is available. This is also true of the Seasonic M-12's. The Corsairs are built to higher standards than the Antecs. From PC P&C's Power Supply Myths Exposed!: http://www.pcpower.com/technology/myths/ 8. ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL? With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you'd think it was a better design. Unfortunately, it's not! Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply's rating. Those losses occur because power literally gets "trapped" on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system. Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete. PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV. From Silverstone: http://www.silverstonetek.com/products-da750.htm "With the knowledge that single +12V rail power is the next generation power supply, SilverStone Technology introduces Decathlon series, offering enthusiasts more choices with single rail power selections to handle their system." |

These quality brands are highly recommended, however not every power supply they offer will meet your needs, be especially careful to make sure that the +12V rail(s) offer a Minimum of +12V@26A for Single Video Card Systems & +12V@34A for Dual Video Card (SLI/Crossfire) Systems & More is Better!. Class 1: These are the Best: PC Power & Cooling (All Turbo Cool & ULTRA-QUIET SILENCER 610W & 750W), Seasonic (S-12, S-12E+, M-12), Corsair, Silverstone (Zeus models ST56ZF, ST75ZF, and ST85ZF), Etasis & Zippy. Class 2: Antec, Enermax, Enhance, Fortron (FSP), Hiper (Type-M 670W & 730W & Type-R 730W) I-Star, OCZ Technology, PC Power & Cooling, Seasonic, Silverstone, Sparkle, Tagan, Thermaltake ToughPower (Only the ToughPower Line!), Vantec & XCilo.

draw for each individual rail and then provide at least an additional 20% for overhead.
All PS calculators use averages, they are not precise.
A 1000Watt PS is useless if that wattage is delivered on the wrong rail(s)!
All of the above are very good PSU's & are recommended.
My personal "BEST BANG for the BUCK" choices are:
$38: XCilo 450W (Lowend to Midrange)
$52: XClio GoodPower 500W (Midrange)
$80: Antec TruePower Trio 550W (Highend to Midrange SLI/CF)

If you require extreme quiet & would like a modular PSU, then the Corsairs were made for you!
Voltages & Amperage: Only the +3.3V, +5V, +5VSB & +12V are used by modern computers. Spec is usually +/- 5%. When the original ATX spec was written the +3.3V & +5V were far more stressed by heavy usage demands than they are in today's computers. Almost any high quality ATX spec PS of 300Watts or more can supply far more +3.3V & +5V amperage than today's computers require. Today's computers, especially the AMD A64's and the latest Intel's stress the +12V rail the most, requiring far more amperage than was originally called for in the original ATX spec for the +12V rail. Video cards can be the biggest +12V resource hogs!
Wattage: Voltage times Amperage equals Wattage. Wattage is the ability to do work; it can be converted into Horse Power. A PS's wattage rating is the total combined wattage output of all the rails combined. Older ATX designs created most of their wattage in the +3.3 & +5V rails, creating very little on the +12V rail. Newer ATX12V & ATX12 V2.0 designs are creating ever more wattage on the +12V rail, to meet the needs of today's & tomorrow's computers.
To see why total wattage should never be used to select a power supply, but that the properly allocated wattage is very important in selecting the proper PS, please click on the following link to the ONLY "Power Supply Calculator" that I can & DO RECOMMEND, provided by & constantly updated by "mnemonik23": http://www.extreme.outervision.com/
PC P&C Power Supply Selector: http://www.pcpowercooling.com/produc...lies/selector/
Multipul +12V Rails: Most PS's today supply all of their +12V amperage through one rail, just like almost every PS manufacturer supplies their +3.3V and +5V through one rail each. However some forward thinking manufacture's are supplying their +12V amperage through more than one rail, the most common today for PC's is to use two +12V rails or dual rails. The new ATX12 V2.0 spec. also requires dual (or more) +12V rails. This has both advantages & disadvantages.
Why more than one +12V rail? Electrical isolation for noise and improved load/voltage regulation. Some devices, usually electromechanical ones having motors, produce noise spikes & voltage fluxuations, these can include pumps, compressors, fans, drives, lights (when turned on & off) and probably TEC's & Peltiers. By putting these "noisy" devices, that often turn on & off, or at least often change their power (amperage) demands, on a separate rail we isolate them from the MoBo, CPU, Video Card(s) and the other electronic components that are sensitive to noise & sudden changes in voltage. This can be a good thing! ATX12 V2.0 is the future.
Additional Dual Rail Information: http://forums.extremeoverclocking.co...62#post1371562
Hold Up Time: Measured in milliseconds (ms) is how long the PS will continue to supply in spec voltage & amperage, once the AC input voltage is removed. The longer the hold up time generally the higher the quality of the PS. Hold up time gives the time necessary for an Uninterruptible Power Supply (UPS) to switch to batteries and allow uninterrupted operation of the computer.
Efficiency and Temperature: There are no electronic devices that are 100% efficient & PS's are no exception. Typically PS's operate between 60% and 85% efficiency. The more efficient the PS, the less power that is lost as heat and the lower the cooling requirements. Newer PSU's meeting the ATX12V 2.xx specs have efficiency ratings from 70% to as high as 85%. The "80%+" certification requires 80% or higher efficiency.
Reading and Adjusting Voltages: BIOS and software such as Motherboard Monitor 5 (MM5) can not be fully trusted to give accurate voltage readings and since many of today's better PS's allow the user to easily adjust their voltages, it is very important that a voltmeter/multimeter be used to measure these voltages correctly.

There is also the fact that I'm basically lazy & using new egg made this much easier! I am now trying to link the factory specs & use Google/Froogle for lowest pricing.
Other PS's: I am not perfect or all knowledgeable, it is highly probable that I have made errors of omission, please forgive me as I have done more or less the best that I could given the restraints of the real world. I am sure that there are other PS's that deserve to be recommended and with any major price changes my recommendations might have been different.
I update this guide as often as possible, already (11-4-04) as a result of suggestions by knowledgeable EOCF members 4 additional PS's have been added to the recommended list. Please add your experiences, comments & recommendations to this thread. They will be appericated.

Use 2 or more PS's: It is often better & cheaper to use more than one PS to power your computer. There are two methods of doing this, the first is simple & safe, the second requires the skills of an electronics technician and if performed improperly could damage your system, and so we will concentrate on the safe & simple method.
Use a second PS to power your lights & fans and maybe your HDD's, FDD's & OD's. Allowing your main PS to concentrate on your MoBo, CPU & Video Card(s). As your lights, fans & various drives are electrically isolated from your MoBo, this is safe & simple, allowing you to use as many PS's as required, to power all of the eye candy imaginable. Turn your Fans & Drives "ON" first & turn them "OFF" last.
To be recommended to power a modern system the power supply must meet the following criteria:
(1) It must meet all usual ATX, AMD, Intel & UL standards for USA operation,
(2) It must have been manufactured by a well known reputable company, known to offer products of very high quality, their products having been used, tested, reviewed & recommended by many experienced & knowledgeable users, and
(3) It must supply a minimum of 26A on the +12V rail(s), as this is critical for today's computers.
To be recommended as a "BEST BANG for the BUCK", in addition to meeting all of the above criteria,
the PS must clearly supply more +12V amperage for less money, than its competitors.
Cheap, but Good Power Supplies! http://forums.extremeoverclocking.co...&postcount=197
To be recommended for "Premium Choices", in addition to meeting to meeting the basic criteria,
the PS must be of exceptional quality, literally being one of the very best in the world.
Many of these also offer special features not usually found on lesser PS's,
such as tighter load/voltage regulation, extreme power, silent operation or user adjustable voltages.
To be recommended for "Professional Choices", in addition to meeting to meeting the basic criteria,
the PS must have been designed & built to the exacting standards required to
power professional workstations & servers, where failure is not an option.
These PSU's must be "The Best of the Best of the Best"!
