1/10 Do not buy this power supply!
Mainemoose77 - 03/09/09
I build and take care of hundreds of computers for a University. I have a degree in Electrical Engineering. I have used many Coolmax@ power supplies. I placed an order for six model CX-400B Coolmax power supplies. Two failed within a couple months, three were DOA. Testing of the units show overvoltage, and lack of voltage control. Many motherboards were tried, the result was rebooting, failure to start and damage to one motherboard!! Warranty at Coolmax says they will replace them, but it shows someone at the company was asleep at the wheel during the production and inspection of this power supply. All of the replacements had the same problems. One half a star is one half too many! Do not buy this power supply.
