I find a nice inexpensive PSU Corsair's replacement?

Just exploring and when I saw a brand called Amacrox 85+ 650W, I wondered, is that 85% efficiency? It's only $80! Then I explored and found this article and am really surprised about its impressiveness; it has 80+ certification and in the article test it gives 82-85.8% efficiency, can work up to 649.5W and even it gets to 813.5W - 125% overload!

Amacrox 85+ 650W spec: +3.3V@30A, +5V@30A, +12V1@18A, +12V2@18A, +12V3@18A, +12V4@18A, -12V@0.8A, +5Vsb@3.0A -

Corsair's 650W PSU:

Corsair 650W spec: +3.3V@24A, +5V@30A, +12V@52A, -12V@0.8A, +5VSB@3.0A

Compared to Corsair's 650W, it brings greater power and higher efficiency. If this is true, technically it's better than Corsair's PSU. What do you think?

  1. For 9.99 more I would go with a proven brand, you dont want to leave your computer running one day by itself and come home to a burnt down home :) I would go with a proven name. Good luck.
  2. And don't forget that early competitors gave cheaper price and similar product quality.
    Corsair maybe more expensive due to overhead cost and... marketing..?
  3. Looks like a pretty nice PSU. But I will stick with my Corsairs and Antecs.
  4. Although there is comfort in sticking to known and/or favorite brands (I too would most likely choose Antec or Seasonic), if Gabriel reviewed it that well, including finding over-spec'ed internals, I'd at least consider it safe; although he notes there is no MOV in the AC filter, so make sure you have a good surge suppressor in front of it.
  5. looks like a good PSU, except for no surge protection. Although in the real world a power surge from a lightning strike or such is going to jump across surge protection anyway. Its always hard to tell from even the best reviews how long the PSU will last for. Its got well known brand caps so It should be ok....
  6. Thanks everybody. IMHO 125% overload means this PSU is durable at least, so it won't breakdown early. About surge protection, though, is maybe the issue. Perhaps this is solved by buying other surge protectors. Any good recommendations on the surge protector?

    It's due to brand recognition.

    Corsair's PSU are either built by CWT who has a very good track record and quality/reliability, or by Seasonic who's track record and quality/reliability is at the very least excellent.
  8. for what you spend on an extra surge protector you could buy the Corsair PSU
  9. ^True. I'd get the Corsair.
