Conclusion And Recommendations
The current crop of 80 PLUS Gold-rated power supplies in the 700-900 W range demonstrates what modern power supplies can really do. Each unit we tested easily accomplished the demanding tasks we threw at them.
However, there were a few small (but meaningful) differentiators among the four devices. Seasonic's X-760 and FSP's Aurum AU-700 performed especially well. The latter boasts both the best test results and lowest price. If you simply cannot do without modular cable management system, that leaves Seasonic's unit.
Antec's HCP-850 is likewise free from glaring imperfections, save the lowest efficiency numbers at minimal load levels.

Thanks for an excellent review.
no pun intended here ;-)
I've used the X 650 in builds for two of my friends. I can't wait to get mine. The cabling is perfect for the Antec 1200 case.
This review would have benefited greatly by including both silver and gold rated PSUs from 750W - 1000W. Some Silver rated PSUs actually perform at nearly at gold levels (Corsair) and so they are a great value.
It would have been nice to have some expert comment on Au's claim that a non-modular cable setup improves efficiency. This appears to be a myth because we see many modular units outperform non-modular units in their class.
Still I really enjoyed this review.
flongGreat review, but where is Corsair???? /citation]Corsair don't build there own PSU:s the are mostly Seasonic built, some CWT. For example the Corsair AX series are nearly identical to the Seasonic X series, the only difference is the fan.
The 'fan-on' at 20% (i think without looking back) is worst case, mine kicks on at about 30-35% depending on ambient temp, so its awesome quiet. Even when on its quiet.
It works very well in a dual gaming/home cinema box...
I'd definiately recommend one
are you guys complete noobs! do you think we need this ...?
