Power Supply Guide - Page 2 - Overclock.net

UPDATE: October 20th, 2006:

This list of recommended power supplies only applies to hardware available in North America and tested by DFI-Street. davidhammock200, Happy_Games, ExRoadie

Enermax Liberty 620w PSU is no longer on our recommended list. Way too many issues with this power supply. DO NOT BUY TO USE ON DFI SYSTEMS!

Also note we've added the Corsair HX-620 (620w) psu and I can honestly say it is EXTREMELY recommended as a top psu, and we've added 3 Antec units, and a Hiper unit!

DFI-Street.com Certified (ie: HIGHEST RECOMMENDATION)

OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply
(personally tested by Happy_Games. This and the OCZ 700w GX are my two favorite psu's!)

OCZ GameXStream OCZ700GXSSLI ATX12V 700W Power Supply
(current top-rated, top-recommended psu by Happy_Games and majority of the forum!)

FSP Group (Fortron Source) Epsilon FX600-GLN ATX12V/ EPS12V 600W Power Supply

FSP Group (Fortron Source) Epsilon FX700-GLN ATX12V/ EPS12V 700W Power Supply

Corsair HX620w ATX12V v2.2 and EPS12V 2.91 620W Power Supply (Active PFC)
(quickly becoming Happy_Games' favorite psu. Modular, strong rails, low-heat, nearly silent...excellent excellent unit!)

PC Power & Cooling TURBO-COOL 1KW-SR SLI, EPS12V, SSI 1000W Power Supply 90 - 264V

Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails
(personally tested by Happy_Games...excellent choice for X1900 Crossfires / 7900 SLI's!)

These PSU's are all very very capable of powering up the latest 7900GT and 7900GTX SLI, 7950GTX, X1800XT and X1900XT Crossfire, AMD AthlonX2/Opteron Dual Core cpu's, and ALL current DFI motherboards including the following:

DFI Lanparty NF4 series original
DFI Lanparty NF4 Expert
DFI Lanparty NF4 Venus
DFI Lanparty RDX200 (ATI)
DFI Lanparty CFX3200-DR (ATI)
DFI Lanparty future AMD socket AM2 motherboards of all chipset flavors
DFI Lanparty future Intel Conroe motherboard of all chipset flavors
ALL CURRENT DFI MOTHERBOARDS AND ANY DFI MOTHERBOARD FOR AT LEAST ONE MORE YEAR FROM THE DATE OF THIS POST UNLESS SOMETHING DRASTIC CHANGES IN POWER REQUIREMENTS!

These are very reliable psu's that are more than capable of doing the job.

Notice that the top 4 are almost identical (the OCZ and Fortron/FSP psu's). They are all manufactured by Fortron, and are the highest recommended psu's in the forum as they have the largest user base, and the least amount of complaints.

I always recommend the OCZ psu's since we have a few OCZ reps in this forum who have always been more than willing to help out mutual customers (and they have even helped out non-OCZ customers!). The only real difference between the OCZ and FSP power supplies is the OCZ psu's have a blue LED fan, and the Fortron psu's do not have any LED fans.

And finally, the 850w PCP&C psu. Everyone should by now know that PCP&C is the maybe the top name in power supplies...but you pay a premium for them.

The 510w version is extremely solid, but we simply cannot recommend it for the highest high end setups like those mentioned above. For that, you want to have any of the psu's on this list, including the PCP&C for your ultimate power needs. If you can afford this thing, you definitely want it.

Again, if you want a solid power supply that is reliable, trustworthy, and a growing majority of the users here are turning to, choose one of the OCZ GamerXstream power supplies. My personal favorite is the 700w (see the sig of Happy_Games)

OCZ BleedinEdge Support Forum

Andy@OCZ
Ryder@OCZ
Tony@OCZ
Marcus@OCZ (EU)

All of the above are EXCELLENT PSU's & are THE MOST HIGHLY RECOMMENDED!

My personal choice for the most demanding systems is the Corsair HX 620W from only $150!

If you are NOT running UBER SLI/CF, then the Corsair HX 520W is my #1 choice from only $105!

If you have the bucks ($549!), the new PC P&C 1KW-SR (Single Rail: +12V@72A) is one of "THE BEST PSU's MADE".

My personal choice for "BEST BANG for the BUCK" is the OCZ GXS 600W for about $85!

One special note, if you require extreme quiet the the new Seasonic M-12 600W/700W should be available soon!.

OCZ PowerStream 600W WARNING: The OCZ Powerstream 600w is a fantastic power supply but it is NOT recommended for X1900XT/7900GTX or newer Crossfire/SLI. Avoid if you plan on using them in X1900XT Crossfire or 7900GTX SLI, or any newer Crossfire/SLI setup!

These quality brands offer "known good" PSU's,
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) Systems.

Our Most Recommended PSU: OCZ Technology GameXStream 600W/700W

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, Mushkin, OCZ Technology,
PC Power & Cooling, Seasonic, Silverstone, Sparkle, Tagan, Thermaltake ToughPower (Only the ToughPower Line!), Vantec & XCilo.

Class 3: Hiper (Type-R 580W, 530W & 480W) & Sunbeam.

Unless we specifically recommend a PSU, please do not buy it,
as we only recommend PSU's that we have actually tested with DFI mobos!

Why do people buy these?

There are PSU's for under $30/$40 in the "Complete PSU Guide" with more +12V amperage!

These 2 TT PSU's are the "poster children" for DFI's 480W+ requirement &
based on these it should be a 600W+ requirement!

Nvidia Certified PSU's: http://www.slizone.com/object/slizon..._powersupplies

The only Coolermaster certified for those GPU's in SLI is the 850W.

Coolermaster hides their true specs: http://www.coolermaster.com/installa...P-650-PCAR.pdf

They do not state their max combined +12V amperage or wattage rating.

+12V@36A is not enough for 8800's in SLI.

Sorry,
Dave

*Chozart* · 03-14-07

And it's in most cases true that you cannot just add the rails up. Check my FAQ on that

StarryNite · 03-14-07

Need to add the PCP&C myth links about modular PSUs, too.

And that PCP&C also will make you a custom PSU (like with external pots for uber overclockers who need spot on voltages/amps).

I love this Seasonic, quiet cool with +12v @ 11.977; +5v @ 4.972; +3.3V @ 3.28, all within tolerances.

Zippy Gaming PSU's - All are Single +12V Rail!

These are very high quality PSU's & if you can find them they will be expensive.

The Good: Single +12V rail with load regulation almost as steady as the Hand of God!

The Bad: Not 80%+ efficient & they can get loud when loaded.
