5 out of 5 eggsGreat power supply, better customer support!

Pros: This power supply is surprisingly quiet and does not run hot, even under a 4x GPU load.

Cons: The power supply is rather large. It will fit in most cases, though.

Other Thoughts: Coolmax support is EXCELLENT. After owning this unit for a few months, one of the PCIe power cables smoked. I'm pretty sure this was caused by my GPU drawing too much power. I e-mailed Coolmax support to find out where I could buy a replacement cable and they instead shipped me a new one. I have not had a customer service experience like this in a long, long time.

3 out of 5 eggsDOA

Pros: Cables and attachments. My new motherboard has 2 - 8 pins, 1 - 6 pin, and 1 - 24pin for its onboard connectors. This power supply had plenty of connections no problem at all.

Cons: The part was DOA. It will power the "stand by" lights on the board and as soon as you try to turn the motherboard on the power supply goes to non-operational. At first I thought it could be the board, however after replacing this power supply with my old one (which doesn't even have 2 - 8pin connections for the board btw) the board will come to life and the fans spin up etc.

Other Thoughts: I would say the most frustrating part of this whole process is when I went to coolmax's website. You can only mail them. You can not talk to someone on the phone. Personally, if I am going to pay this much for a power supply a phone number to discuss issues sure would be nice. So in short their lack of Customer Support is more frustrating to me than having to ship the DOA poer supply back to new egg for replacement.
