Not true. between 40% and 60% is the best efficiency. Above and below that the efficiency drops.

Guys, a 6950 can and will run fine on an Antec Neo Eco 400C. Yes, you'll need a Molex-to-PCIe adapter. No big deal.
Check the power consumption graph for the 6950 at http://www.anandtech.com/show/4061/a...eon-hd-6950/24
320W in Furmark for the whole system, measured at the wall. That's 272W drawn from the PSU, assuming 85% efficiency. The Neo Eco 400C will laugh at it.

Furmark only stresses the gpu nothing else... full system on with a phenom x6 and everything else he has will bring his system over 400w. 550w would be perfect for him as he will get pretty decent efficiency with it.

Even at full load it would be fine. He has a Phenom II X4 by the way. Regardless, systems are never at full load unless you fold. Check the graph for Crysis then, that uses the CPU as well as the GPU, and it's a lot more representative of a typical gaming load. The load is even lower in Crysis than in Furmark.

Cutting it too close to what? The Neo Eco 400 is rated for 360W@12V. With efficiency, the worst case scenario presented in the links you posted show a 330W load on the PSU. It's perfectly fine.

Thats with just the GPU.... add another 100w atleast for the AMD x4 and it's over 400w... If he tries to play a game it WILL crash that's a guarantee. The comp will only be good for internet browsing which ruins the whole point of buying a gaming card.
