COOLMAX CX-400B 400W ATX v2.01 Power Supply

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).

Other Thoughts: 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: It was a good PSU

Cons: Too bad it died and took my mobo and RAM with it!

Pros: It's still running!

Cons: None really

Pros: Sleek look.
Average Power Rating.
Extra SATA power connectors from Molex.

Cons: Its not really 400W...
ITS REALLY 375W...

Other Thoughts: 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: Great Power Supply, Havent had any problems with them

Cons: None

Other Thoughts: Have bought several

Pros: Cheap.

Cons: Coolmax CX-400B power supply died after 13 months. And the warranty is only 1 year. Value Engineering in action?

Pros: Works fine, relatively quite. First used with PC Chips MB w/Athlon 64 FX (cooler mount broke). Now a MSI H67MA w/Core i3. Still running strong.

Cons: none

Other Thoughts: none.

Pros: Nice looking, quiet, and steady as can be.

Cons: Some of the connectors feel a little cheap.

Other Thoughts: I've been using this unit since 12/04 with no problems whatsoever. Once, I bought a new graphics card and was having issues, so I assumed the p/s was not up to the task. Wrong. The problem was the motherboard - replaced that and this thing has been humming along ever since...

Pros: Almost 6 years old and still running strong. Below is what it is running:

Cons: none

Other Thoughts: Computer has been running flawlessly with win xp.

Pros: Low price, looks nice, and it powers the computer.

Cons: Not silent. VERY cheaply built - metal casing and connectors feel flimsy. Too many Molex connectors and not enough SATA connectors. One of the Molex connectors wouldn't fit on the optical drive, but I tried another one and it fit fine. One of the SATA connectors (of which there are only 2) broke when I connected it to the HDD. Used the other one and it was fine.

Other Thoughts: The only reason I bought this PSU to begin with was because of the mail-in rebate. I would not buy it again.
