Power Recommendations by Video Card

**ceewi1** · 07-08-2007, 11:16 AM

This list is a consolidation of official, manufacturer supplied power requirements for PCs by video card. It is intended as a first resource when choosing an appropriate PSU for a system or video card upgrade (or choosing a video card that will work with your current PSU).

Keep in mind that these figures are based on a typical gaming system including the specified video card. Users with multiprocessor systems, large RAID arrays, or other power sucking devices will need to use a larger PSU than is specified here.

Figures in blue are those which I have extrapolated, due to manufacturer data being unavailable. If anyone has any additions or corrections please post/PM me. I will endeavour to keep this list updated as new cards are released. Be aware that some manufacturers specify different requirements for the same card. In this case I've taken a little licence when choosing the figure to use.

Reserved, in case this list grows.

this is very helpful and is SO easy to comprehend!! thanks a lot!!

**oscaryu1** · 07-28-2007, 09:12 PM

Agreed. very good, except that where are the Nvidia LE cards? Maybe you should go back a bit... um... Geforce2

lol jk

**ceewi1** · 07-29-2007, 01:41 AM

Thanks guys. 7300LE added. Significantly older cards like GeForce 2s typically have very low power consumption by modern standards and would fall into the Other lowend/Integrated category. I haven't gone back as far as most of the 6 series mainly because official figures for them aren't as readily available.

INTELCRAZY · 11-15-2007, 03:16 AM

Could you add the new 2600GT to the list?

**ceewi1** · 11-15-2007, 03:59 AM

2900GT added. I'm not aware of a 2600GT, though?

There isn't one

**oscaryu1** · 11-15-2007, 04:36 AM

One question Ceewi1, I had an 250W with 15A running my sig. In the middle of getting into the Warthog in Halo, our power went out. I heard an *sss* in the PSU... power came up 2 seconds later... ?!?! What happened? I don't get it? An few days later with another PSU (low end too) it did the same thing!?

AC power failure? Did everything else lose power as well? Or did the PC just reset?
