2 out of 5 eggsMeh

Pros: Nice packaging, came with extra screws and alot of padding to ensure it didn't get damaged from the carrier.

Cons: was DOA, cougar makes some nice stuff so it might have been a fluke, but its risky, i immediately got an RMA for it.

1 out of 5 eggsDOA

Pros: none

Cons: installed in case, connect to mobo, turned on, very very loud noise, I think from the fan bearing being unbalanced. Returned and bot Corsair for the same price. Newegg was prompt with the refund.

Other Thoughts: Bot it because it was tagged a new arrived and figured it must be really good.

4 out of 5 eggsNo SATA Data Connectors

Pros: It's a great psu, the price for 600W is really nice, It's quiet and has a good range of connectors and is really up to date, fits nicely into my case without a problem.

Cons: There are SATA Power connectors, but no data connectors. I feel that this is the only con since I had to order some SATA data cables but it's not much trouble.

5 out of 5 eggsActually a great PSU for the price!

Pros: Over Voltage Protection, 80% efficiency, ULTRA-QUIET & TEMPERATURE-CONTROLLED 120mm FAN, Over-Voltage-Protection (OVP)/ Over-Power-Protection (OPP)/ Under-Voltage-Protection (UVP)/ Short-Circuit-Protection (SCP)!
In short this is a reliable PSU with all the features of name brands, I took a leap of faith on buying from an unknown manufacturer but this turned out to be great! Runs SLI mid range cards just fine with plenty room for overclocking!

Cons: Cheap looking (aluminum?) screws included, but I had extras.

Other Thoughts: I wanted to wait and see how this worked after a week of use 24/7, before I made a review, and so far so good!
