I'm not usually the guy that under-estimates around here, but seriously you don't really need more power than that.

Is there such a thing as "too much power"?
Generally, no. A power supply only puts out as much power as needed by the system's components. In some cases, an 800W power supply may actually use less power from the wall than a 500W power supply, depending on the efficiency of the units. Often times, buying an "oversized" PSU is a good choice due to it's ability to perform even under higher temperatures, a quieter fan because the unit is delivering a lower percentage of it's total capability and considerable system upgradability without having to worry about having enough power when upgrading a graphics card, adding a graphics card for SLI or additional hard drives.

Are you saying I'm contradicting myself?

I'm not.

Chris only needs a 450W or 550W if he's doing SLI (the Corsair HX520W would probably work too, but not many other < 550W will do the job long term.)

I would be more than happy to send Chris in the direction of a higher wattage, higher quality unit (unfortunately, sometimes you can only get the really top notch quality in higher wattage platforms because it's cost prohibitive to make them in lower wattages) but he has a budget. Apparently a very tight budget.

There is no such thing as too much power and, like I said, I typically don't like to under estimate. I usually like to have a PSU that twice what I need, but I don't think Chris is going to find any decent 700W~800W PSU's for under $100.

jonny I see a lot of PSU's that list multi 12v rail specs such as 3-17 amp rails but is only around 500 or so watts and I know that they can't put out 51 amps.How do you find their total max amp output if they don't show it in their specs?Is their a easy way to find this?

Here is a example,this 600 watt claims 4-18amp 12v rails but it can't have 72 amps on the 12v.How do you find the total 12v rail output?

Your the Guru

I have been reading you for years...
This is what i would have recommended though:
http://www.newegg.com/Product/Produc...82E16817371001

Its actually cheaper than the 550 trio right now.
I feel its better to prepare for future upgrades when swapping out supplies.
Why do it twice? Especially when the cost is right there...

Im going to probably go with this. http://www.newegg.com/Product/Produc...82E16817103941

Look like all around good specs and alot better the my crappy xclio.

the psu's job is to convert alternating current to direct current. most any psu though can not convert from a alternating source to a pure direct current. with that they all have some sort of fluctuation in the voltage still although usually small.

look at the image below.
the orangish line is 0 volts. the input voltage is the black line and you can see it swings from positive to negative. the red line is the goal and as you can see it is dead steady. usually though that doesn't happen and so you end up with the blue line where it fluctuates a little bit though still easily stays in the positive area. that small fluctuation is the ripple voltage and you want to keep that to a minimum. our jonnyguru has shown that the ocz gamerextreme has some issues where at higher loads the voltage will have more ripple then desirable. I believe at or near max loads it even exceeded the ATX specs for how much ripple a psu is allowed to have.
with this ripple it can cause some noise on the line that can cause some problems with stability.

with your computer though it is doubtfull you would even put enough of a load to make this a problem. this was more just to explain it a little more for you. to explain what ripple is at least.

Well, this has been hashed and rehashed every time someone brings up the whole single vs. multiple +12V rails argument, but essentially what you have their is proof positive that the "trapped power" claim is complete B.S.

I'll try to reiterate: Multiple +12V rails all come from the same source. The capability of that source is what you see listed under "total combined output wattage". The separate rails are split off from this source. Each rail has a limit as to how much powe can be delivered to the connectors on this rail. So the amperage that you see the rail rated for is not really a gauge of capability, but more of a designation of the maximum power that can be delivered off that rail. You wouldn't add these numbers up to get the PSU's +12V capability because the numbers don't really represent capability in the first place. They merely represent a "limit".

I knew that but they don't always show the the max amp of the PSU,just the rail limits so how do you find the max amp output if they don't show it?

In that example, it's 580W.

The reason why the line goes under the +3.3V and +5V is because you can EITHER load the +12V up to 580W, or any combination of +3.3V, +5V and +12V up to 580W.
