Easy to install with plenty of connectors on the wiring harness. My PC monitoring software shows the voltages supplied are within specs. I am very pleased with this unit.

-------------- Initial review --------------------------------------------

This power supply failed after 5 weeks in use. It began causing spontaneous reboots of the PC, which was cured by the replacement of the power supply. It has a 1 year warranty and will be returned to CoolMax for replacement. I will report on their service when the problem has been resolved.

CoolMax replaced the defective unit, but I had to pay the shipping to return it. If you are looking for a reliable power supply, I would consider other brands.

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. One star is one too many for this product!

This unit is a litte on the noisy side.However, if this is not a problem you will probably find it to be a good solid power suppply.

The instruction manual is excellent. It looks and performs in an excellent manner.

Using the power supply for a while now. It has been working great and is not too noisy.
