2 out of 5 eggsHopefully if the warranty gets them to send me a new one...

Pros: None so far

Cons: I hooked up the power supply, turned on my computer and the 4/8 pin wire fried and melted. Hopefully I just got a bad one and if they send me a new one it will work, will review if I receive another. 2 star review due to the fact that I spent this much and the product failed on first startup

5 out of 5 eggsPretty Good PSU

Pros: 80 Plus Bronze
Semi Modular
Sleeved cables

Cons: I can't think of any.

Other Thoughts: It is not the best, but for the money, it is a nice choice.
The brand may not be so popular i guess, but I've had no problems with it so far, so that's okay.

5 out of 5 eggsGreat PSU

Pros: Ultra Quiet

Cons: Can't think of any

Other Thoughts: The secondary power connector was a bit of a stretch. It literally barely fit going around my graphics card. Other than that its amazing I've had this for 1 month with no problems. It is insanely quiet. My case fans are much louder compared to this mute device.
