User Review

  • Summary: Runs very quiet. It was very simply to put in, but the power cord is a bit short (4 ft) but I use my old one. Worth every cent.

Overrated Junk (275W PSU)

David C., Newegg
17 March 2014
  • Summary: Don't give these guys your money, they don't deserve it.
  • Pros: Coolmax has been "updating" this model of PSU, but mostly downgrading it further. It does have some pros though...barely. It uses a nice quality fan, and even though it's wired straight to the 12V all the time (No thermal fan control whatsoever) it stays quiet, and the bearing has plenty of grease so it shouldn't fail. The older revision of this PSU used the infamous two transistor circuit for the +5VSB, which wasted a lot of electricity and killed lots of motherboard...
  • Cons: Everything else... The old revision (Circa 2009) could pump out about 350W, this one is capable of about 275W (With a very mixed rail load). It claims two 12V rails capable of 348W. HA! It only has one rail, and it uses a 16A ultra fast rectifier. Since the fan runs fast keeping it cool, I bet it could do the full 16A, but that's only 192W...Almost 90% of your computer uses the 12V. That makes this basically a 200W PSU in a modern system. And if you load it up, that 1...

Loud, no fan switch as advertised.

Anonymous, Newegg
6 November 2013
  • Pros: It worked for the 30 minutes that I used it...very loudly.
  • Cons: The box advertises a fan switch, and the unit pictured on the box shows on. This switch is missing from the actual unit, and the thing sounds like a jet engine with the PC mounted in the computer desk. It's literally intolerable. Fix the packaging and don't advertise a switch that isn't there.

Needs lubrication

Pavel R., Newegg
13 November 2012
  • Summary: I have other power supplies that have been working for years quietly, without requiring to be lubricated. I cannot recommend this unit to anyone.
  • Pros: I bought two units and both have been working fine for years. The units are very quiet if they don't need lubrication. They worked after the hurricane Sandy, when some other PSUs refused to turn on, probably due to flaky mains power.
  • Cons: Both units became noisy after a few years of use. I had to open both of them and lubricate the fans with garage door lubricant. Both are quiet again. The device shows its age. Who needs so many molex and floppy connectors? And 2 SATA connectors are not enough for anything beyond the simplest setup (one hard drive and one optical drive).

Not Enough Power...

Arlene C., Newegg
6 July 2011
  • Summary: I needed 400W, at least, to run a video card (when this is really 375W)... they lied... it won't last more than a month before it fries... DON'T BUY IF YOU NEED MORE POWER...
  • Pros: Sleek look. Average Power Rating. Extra SATA power connectors from Molex.
  • Cons: Its not really 400W... ITS REALLY 375W...
