it works

white Reviewed By: blinkn on 1/28/2010
Rating + 4
Tech Level Tech Level: average - Ownership: 1 day to 1 week
This user purchased this item from Newegg
Pros: It works and it fixed my dead PSU problem on a Dell. After initial start up, it is fairly quiet, as advertised.
Cons: Only 1: it did not come with attachment screws. Luckily, I was replacing a dead PSU, so I had the screws already, but if I were building a system, I would be a bit upset. (This is the reason for taking an egg) - do not let this deter you, if you need a cheap working PSU, this can do the job
Other Thoughts: So far so good, but since it does not come with anything but the box, PSU, and power cable, it is more of a replacement for a dead PSU than for a new system

Tech Level Tech Level: high - Ownership: more than 1 year
This user purchased this item from Newegg
Pros: Plenty of cables for a socket 754 board. Seemed to run fine for ages. It seemed to run a bit hot.
Cons: Died after 2 years. Began resisting the initial power-on. Eventually died while running and took my 6600GT with it. I don't think it was a surge.
Other Thoughts: My CX-350 recently died, too, which I bought a year earlier. It did not take any hardware with it.

Buying all other brand PSUs these days. Buying an inexpensive PSU is _not_ worth it.

I spent easily the $50 I saved not getting a $100 PSU on replacing parts on the failed box to see what was causing it to BSoD; and that was after replacing the dead PSU! 100% stable before the CoolMax died.
