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.
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 ...?

Fix'd.
Efficency, being modular, Cable quality, and Amperage. Larger priced models have more features, and that's why companies like Corsair usually have a large array in a series such as their "Enthusiast Series."
Stand back. These psu are for people who Do things your pc will not.
I have the seasonic. Let me tell you my system dosen't crash. It never fails. Its runs every thing. I can run Crysis and watch HD on two different screens. Do that with your oem PSU>
Actually, this isn't true anymore. Corsair does have other manufacturers build its PSUs but it has its own specs and it tweaks them. But even if the Corsair PSUs are similar to the Seasonic, they deserve to be in this lineup.
Sure I spent $280 on a PSU....because for at least the next 7 years I will never have to even think about getting a new PSU again.....so for a dime a day I have one of the best PSUs ever made.....Good luck making me feel bad about that
Two things that got me this time(much less than last time), you ding the HCP 850 for only getting 60% efficiency at 3% of its max load, no system that it should be running should be at only 25W at idle, and you also dont say your load distribution for your custom load profiles, heavy 12V will yield better efficiency while heavy 3.3V and 5V will hurt the efficiency.
And i still want to see shots of the innards, because most PSUs can pass for the short term, but one with 80C rated chinese caps wont make it too long past the initial test, and its the quality of the innards that tells you if the initial quality will stay around for 5 years.
