EVGA 8800GTS 640MB Superclocked

[Coherence]

According to Newegg's specifications for the EVGA 8800GTS 640MB Superclocked videocard, it needs a "minimum recommended power supply with +12 Volt current rating of 26 Amps".

I can't even find a PSU that has such a power output on any of its rails. The most I've seen are +12V at 18 Amps.

Anyone know of a good, silent PSU that is recommended for this videocard?

We were looking into getting a SeaSonic M12 or S12 PSU, because they are supposedly the quietest PSU's on the market, but again the rails are only +12V at 18 Amps.

Most newer psus come with multiple 12v lines and combined they would be more than 26amps.

Sounds like it's 26amps total needed, not just 26amps for the video card.

What Thor86 said. Many PSUs will list multiple 12v lines, even though they really have a single 12v rail. Some will give a total W for the 12v lines, for example 408W. Divide that by 12 (408/12 = 34amps), to find 12v rating in amps.

When I bought my PSU, some people here on AT, laughed at me, talked bad about it, etc.

Anyway, it still hasn't failed me...

It has 44A!!! That is 22A on each of the two 12V rails.

It does not have 44 amps at all.

It probably has about 38 amps, which is still very good. For the zillionth time, you *cannot* just add the 2 rails to get a total amperage. There is an exception to this rule, OCZ I think, it's one of the major manufacturers anyway.

You must not be looking very hard. My old Antec TB 480 is rated for 28A on the 12v rail. This was made before the multi-rail fad (which is utterly pointless) came into being, but I find it hard to believe there are no PSUs out there that can deliver 26 amps, or more, current of 12v power.

He's talking about needing 26 amps on one rail. No, you do not need to have 26 amps on one rail, just 26 amps total.

26A on the 12V rail means it should deliver 312W on the 12V rail. (26x12)
For reference, an Antec NeoHE 430W PSU delivers 32A/384W combined on the 12V rail - the specs say 16A (peak) on 12V1, 12V2 & 12V3 each. You can't always add up the numbers.

I just looked at the Seasonic S12 specs on their site and there, you CAN add the numbers. For example, the S12-500 lists two 12V rails - 17A & 16A. If you add them up, 33Ax12V=396W which in line with what you would expect from a 500W PSU.

BTW, the card itself uses 10A-11A. The recommended spec is for a typical system.
