1 out of 5 eggsCustomer Support Nightmare

Pros: Had this product for over under a hear and a half. No problems and ran quietly up until that point.

Cons: I looked through all the of items before purchasing and checked reviews, specs, and company information. At the time this unit was most cost effective and had fairly good review. Unit failed suddenly, I looked up the company website to look at how to get a repair considering they note a 5 year warranty on their product. The website no longer exists, no contact information, nothing. The link on Newegg Contact Manufacturer page is a dead link.

Other Thoughts: Go with a unit you can have repaired in your country.

4 out of 5 eggsThick cables

Pros: Simple, feels solid. Its what you expect out of a powersupply. Lots of interchangeable cables. completely ready for SLI/Crossfire.

Cons: The cables are thick and rigid, makes them durable, but cable management is nearly impossible. If it wasn't for this I would give a 5-egg.

Comes with nice bags and some ties for your wires
Plenty of wires to fill any gaming rig, thick wires that are built to last

1 out of 5 eggswouldn't power motherboard

Pros: none, sent it back defective

Cons: Power supply fan started turning before turned on, system fans kept turning on and stopping after a few seconds. Replaced with a locally purchased 850w plugged in exactly the same way, and the system worked-problem confirmed. Wasted expedited pick and second day shipping cause of it.

Other Thoughts: I did not see any user reviews, till today.
