no psu compatible with 8800gt?

[hotspot_102]

nvidia lists that the 12 v rail needs 22 amps, i cant find a psu that offers 22 amps on the 12v.

any suggestions? or am i misunderstanding?

Many PSU's list multiple +12v rails. When combined these generally are more than 22a depending on the PSU. Others have a single large +12v rail.

An example of a multi-rail that would work would be this. http://www.newegg.com/Product/Product.aspx?Item=N82E16817371007 To calculate the total +12v amps available you would divide the total +12v wattage by 12v. The remainder would be the total +12v amps. For this PSU that would be 34a. http://www.newegg.com/Product/ShowImage.aspx?CurImage=17-371-007-04.jpg&Image=17-371-007-02.jpg%2c17-371-007-03.jpg%2c17-371-007-04.jpg%2c17-371-007-05.jpg%2c17-371-007-06.jpg%2c17-371-007-07.jpg%2c17-371-007-08.jpg&S7ImageFlag=0&Depa=0&Description=Antec+earthwatts+EA500+500W+Power+Supply

An example of a large single +12v rail would be this at 33a. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003

If you were thinking of a dual card SLi setup, this would be more appropriate. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341002

All three above would serve you well.

Ironically, I have a PSu that came with case that claims 24A. so they are out there.

Ughnn, I got 60 Amps on mine. /flex

Anyways, 22 amps is the requirement for the entire system, not just the card. As others have stated, you can also combine rails to meet those requirements.

The nvidia recommendations are for a system wide total of xx amps on the total 12v rails. 22a is only an approximate minimum.

The PC power & cooling silencer610 has 49 good amps on a single 12v rail. http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005

it may be a bit of overkill, but it works fine in my system, and is quiet to boot.

If your on the Newegg email list you would have shaved another $10 USD off the price.
Newegg says your "saveing" $80 but PC Power & Cooling will sale dirrect for the same $119.

All PC P&C units are rated full -constant full load- rather than surge and at either 40C or 50C (for the Turbo's) air intake.
Best PSU's made and I get the same OC useing the same parts as others report but -without- haveing to raise any voltages.

@ZOldDude:
My newegg shows free delivery, I think PC P&C charges delivery.

What e-mail list are you referring to? Are you saying that some products are sold at different prices, depending on what list you are on? Am I missing something here?

 

[rgeist554]

You can get those promo codes from newegg for $5-15 off + free shiping, etc.

I think the OP thougth the PSU had to have EXACTLY 22 amps on the 12v rails.

If that's the case, well no, 22 amps is the minimum.
