1 out of 5 eggsUnit does not perform as advertised

Pros: Unit can work fine if you have a lower end system, but I'm betting you're not buying a 750 watt power source if you have a lower end system.

Cons: Unit will not put out anywhere remotely close to 750 watts for very long. You might get an hour at most before the unit completely fails and your PC suddenly shuts off. Unit also lacks almost any safety features, so do not do anything at all while this is plugged in or you can fry your components, HDDs are particularly vulnerable.

4 out of 5 eggsKIlled itself after 3.5 years of service

Pros: Quiet and reliable for 3.5 years of constantly beating it to death in my overclocked gaming rig. Dual GPU high draw cards in it. On ALL the time.

Cons: Well after 3.5 years a coil dislodged from within the unit and fell into the fan while I was away. It melted the fan and locked it up.

Other Thoughts: I'm thinking of buying a new one of the same brand. 3.5 years isn't a bad run.

2 out of 5 eggsloud but bright!

Pros: - Was great while it lasted
- Had LED's that were quite bright.

Cons: - Expected to last longer than two years
- Loud
- not enough cables for me

Other Thoughts: I've never had a power supply last less than 4 years. This was my first one. My wife made me turn my computer off at night because the fan was so loud, and it was downstairs across the house.

1 out of 5 eggsFire sale

Pros: Worked for a while

Cons: After owning this psu for over a year it started destroying my pc, it took out one of my ram, my cd/DVD burner drive completely melted, and hard drive caught on fire I opened case and blew it out to salvage the drive but basically if you don't want to burn your house down spend the money and buy better brand.

1 out of 5 eggsDied, took parts with it

Pros: Worked for a year.

Cons: Died, took mobo with it. Can't even get spare PSU's to run the computer now. Smelled smoke and bam, out it all went.

Really disappointed here. I built a computer for my fiance to play games on and it just cooked it.

4 out of 5 eggsSolid PSU

Pros: Quiet. :Plug 'n play. Did exactly what I wanted. Comes with a bunch of extra connectors.

Cons: The extra connectors are not attached and.I have been unable to figure out how to attach them. The instruction manual offers 0 help. I just ordered a new GSU, so this will soon be an issue.

Other Thoughts: Did exactly what i wanted, but the in-box model offers only enough connections to run the bare essentials. If you plan on adding extras like a second HD, etc. you will need to figure out how the additional cables work.

4 out of 5 eggsDoes the job just fine.

Pros: -Not obnoxiously loud
-Powers a single GPU & HDD gaming setup perfectly
-Includes cables for just about everything you need
-Still running great after 2 years of use
-Braiding on the cables is a nice touch

Cons: -Not a fan of the LEDs

Other Thoughts: All in all, I have no serious complaints about it. It does what I need it to. It has powered my gaming PC for over 2 years now. The only thing I don't like is that it has LEDs and I am not a fan of the whole "fancy lights in your PC" thing.
