Measurements: Antec High Current Pro HCP-850
Efficiency according to the 80 PLUS specifications.
Efficiency based on performance profiles.
The Antec High Current Power met most of our expectations in the test lab, albeit with small lapses. In our review of the efficiency values for the 80 PLUS Gold certification, the device showed no weakness. It was, however, slightly outperformed by the FSP and Seasonic models. The PSU's efficiency numbers at low loads makes it pretty clear that Antec optimized this unit for high-performance environments. Efficiency at 85 W is still a very respectable 81%, but it falls to 60% at a load of 25 W. This is the lowest score in the entire test field.
On the other hand, its rectification of ripple is exemplary. Antec clearly meets those specifications on all of its rails. In all other disciplines, the HCP-850 behaves just as you would anticipate from a high-quality power supply. The pleasantly quiet fan is nice as well; it successfully keeps the unit running cool without generating much noise.
Antec's HCP-850 is well-built performance-oriented PSU, suitable for inclusion in demanding gaming PCs. It's comparatively low efficiency under low loads is notable, but probably not a problem, given the target market. It sells for around $250 online, which isn't inexpensive. At the same time, it's fairly apropos given the competition and this unit's value.
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 ...?
