Unfortunately that adds rather a few cables and Heat. Also a more Bodge job..However its still an option yes.

Chozart said all, we need is 30A total on the 12V rail, that means I could possible run a GTS/GTX? I have a total of 32A on 2x12V rails.

Yup he said it. But the GTX uses like 330 watts, thats like 28A. Even though I have 36A I still want some wiggle room for OCing.

I am going to be getting a dedicated GPU PSU as my power supply just cannot handle my 7900GTO well for some reason even though it should be able to. Also that FSP one cost more than I bought my current PSU for just thought that was kind of funny.

nVidia recommends a 450W PSU with 30A on the 12V rail. There is NO way the card itself draws that much power. I have seen reviews with the 8800GTX in which the whole system draws less than 300W under load.

The initial rumors of the power draw by these cards was extreme. In reality, it's not that bad.

225W is the maximum allowed for such a card but that doesn’t mean it consumes that much. Nvidia suggest a power consumption of 140-170W depending on the manufacturer and the cooling device since it can also drain some power. Real tests made by the guys at Anandtech revealed that a high end PC that uses an 8800GTX series card consumes about 320W. And I’m talking about a high priced Core 2 Duo with 2GBs of Ram here.

I was going by the number people have gotten for power consumption for that card, and they are around 330 watts. Divide that by 12v and you get 27.5A. Im not saying it uses that all the time. But its good to have some room. I mean you start OCing and its gonna bring your watts up there quick.

That's the power consumption of the entire rig with that card, not just the card itself.

Dailytech (http://www.dailytech.com/article.aspx?newsid=4812): full load, 321W for the whole system

I've not heard anyone here saying that the card alone draws more than 300W.

Interesting Speculation. However the DX10 cards dont use too much power as originally expected.
post #39 of 79
Exactly.

again, a 450W PSU with 30A on the 12V rail is sufficient. 500W+ with 35A+ allows for decent overclocking imo.

So if the beafest, most power consuming GPU + a whole rig cosumes less than 350W of power then why do so many people buy 600W+ for non-Sli?
