1 out of 5 eggsPSU suddenly broken

Pros: Power supply was working fine for the initial 3 months, but then suddenly failed.

Cons: A power supply in this price range should definitely not break after three months of moderate use. Also, the support of Enermax is atrocious; I have contacted their support team one month ago and have not received any response.

Other Thoughts: Avoid Enermax PSUs and buy from a different brand, such as Thermaltake. Support is horrible and unresponsive...

Manufacturer Response:

Dear Valued Customer,

We apologize for the inconvenience, normally we process the RMA right away when we receive the unit. Please let us know your RA#, and we will take immediate action.

Thank you,
Customer Service.

5 out of 5 eggsNice PS for the money

Pros: I've had this for a couple months and it seems decent enough although, looks nice, and seems very well made. I wish I had a PS tester so I could hear the fans without my other ones running so I can't tell you if it is quiet or not. Maybe another user can report on that. I'm pretty happy with it.

Cons: None so far

5 out of 5 eggsEpic.

Pros: It powered a GTX 460 and now it's powering a GTX 570, flawless, no problems, worked right out the box, quiet as hell and did I mention it's sexy to look at? I got no complaints, there's everything to love and nothing to hate.

Cons: Not modular? Actually, scratch that.. Wires look better than modular... The braiding is awesome.

Other Thoughts: More pros: Wires are easy to handle, not stiff, comes with a bunch of connectors. Wires are long too!

Bout it.

5 out of 5 eggsGood

Pros: Well, my computer starts and everything including the Radeon 7850 appears to be getting the proper amount of power. Cables are sleeved and I had almost exactly what I needed but there are still some for hard drives or whatnot if I ever need to expand, and there is one more pciE connector if I ever want to cross fire.

Cons: Not modular but I knew this going in.

Other Thoughts: Will update this if anything goes bad but it appears to be running strong and quiet for now.

Probably not worth mentioning but the 4+4 pin appears to be one piece but it is really two parts that separate easily and can be put back together, had just never seen that before in the other rigs I have built.

5 out of 5 eggs

Pros: Bought to replace an 5yr old Antec PSU works flawless out of box. Higher efficiency then my previous PSU with 82% to 87% meaning the wattage pulled from the wall is more closer to the amount your using.

Cons: Wasn't worth removing eggs for but wish it had more then 4 4pin molex connectors.
