well it's not important but just wondering how much power does 8800 gts 320 consumes. i have EVGA 8800 gts 320 MB superclocked. i know pci express can supply max 75 watts and the 6 pin adapter too can supply 75 watts max. so it can't be over 150 watts. but it is over 75 watts for sure lol

There has not been any official power measurements of the 8800 series. NVidia states the 8800GTX consumes a max of 145w. The 8800GTS 640MB consumes 115w, therefore the 8800GTS 320MB should consume less than 115w under the worst possible load.

17a on the 12v rail for a 500w PSU is actually pretty weak. That means the PSU can only provide 204w on the 12v rail, 17a x 12v.

Perhaps you read the specs wrong, exactly what PSU brandname and model do you have? Most 500w PSU have 27a - 30a on the 12v rails.

Well the brand i s Zebronics its there platinum edition. I did read 38a but i am not sure if that was for 12v .

Anyway its a Indian company . http://www.zebronics.net/powersupplies.asp

its a platinum series 500 watt. Any advice would be helpful.

cheers :)

The website does not provide any specs or a picture of the PSU.

You will need to look at the sticker on the PSU to determine how much power the PSU can provide on the 12v rail(s).

Below is an example from the Enemax FMA 535w PSU:



As you can see, this PSU has two 12v rails. Each of which can provide a max of 22 amps. However, it can only provide a max of 34 amps combined. It is not as simple as adding 22 amps on both 12v rails for a combined total of 44 amps.

44 amps would mean that this PSU would be able to provide 528w on the 12v rails; 44 amps x 12 volts. No way in hell will that happen.

Hmm okay ill have to check this out and get back to you .

THANK YOU for your help and time .

I have a 500 watt Antec NeoHE and the evga 8800 gts 320 superclocked and my system runs great! So yes, a 500 watt psu should provide enough juice.

Watch what you say, as not all PSUs are made equal...

Quite often the wattage the cheaper brands state is peak and not sustainable. Antec NeoHEs look pretty good though. I was thinking of getting myself one if I decide to go ahead with an Easter build!

i would say it will be about 100 W
March 14, 2007 11:51:14 PM

So you'd be looking at something that has 20amps and 18amps on respective 12 rails.

A 450W Antec PSU is much stronger than a generic 550W. Don't get fooled by large, theorical and often unreliable wattages; it's precisly how much amperage it can deliver to your video card that counts.

Back to the original question...

I have a kill-a-watt meter on my PC (not extremely accurate but it's close). Running Prime95 on both cores, my system draws between 175-180 watts. While playing battlefield 2142 at high rez, it draws between 235-245 watts. That should give you a rough estimate.

I should also add (for power consumption calculations) that I don't have any fashion show crap like LED fans, color case lighting, etc.
