1 out of 5 eggsFaulty power supply

Pros: Inexpensive

Cons: Unusable
Starts things on fire

Other Thoughts: When my old power supply died, I tried a spare one I had around and everything worked fine. I ordered this power supply, plugged it in, started up the computer and immediately it started my motherboard on fire. I didn't think this was horrible at first as I could return both to Cooler Master. I sent them both and now they refuse to replace the motherboard that THEIR power supply ruined. They also will not refund for the power supply and only exchange it for a new one from them.
I suggest buying from a different company.

5 out of 5 eggsGreat product from a great company

Pros: Stable, reliable, and good amount of cables

Cons: It's not a 1.21 gigawatts PSU.

Other Thoughts: Does what it's supposed to. Has a lot of connections so you can power up a lot of things in your computer.

1 out of 5 eggsDoA?

Pros: Came as part of a bundle.

Cons: During the build I only got it to power the system on once. When I moved it from the table to the desk it won't power up. 20+4 pin cord is a bit on the short side as well for a mid-tower case. Hopefully I can get this RMA'd or something.

5 out of 5 eggsWhat a deal

Pros: WOW!!! Newegg had a promo for these just when I needed it. Plus Cooler Master had a $10.00 rebate so I had to jump on it. $34.99 total for this PSU was too good to pass up especially when my old one just died. Plenty of connections for adding on and also long enough to go anywhere I needed.

Cons: Humming noise compared to my old one but after a few days usage I don't really notice it anymore.

2 out of 5 eggs

Pros: it provide power. Relatively inexpensive

Cons: it is unable to handle a graphics card that it should be able to handle (shuts down during even moderately graphics heavy games). Also, MIR was never returned to me.

4 out of 5 eggsOK, so far

Pros: This fit right in the original location.
Has more power and is quiet.
Economical to get my computer running again.

Cons: The cable for disc and floppy drives is too short. I can only connect one disc drive and have the cable reach the hard drive further down the tower. This computer is a backup and I don't use the both drives anymore but I would've liked to be able to use the DVD player if needed.

3 out of 5 eggs

Pros: -Works Perfectly-
-Not Loud At All-
-Allows me to Overclock easily due to extra Power-

Cons: -None,so far- PSU keeps Buzzing. Think its just my copy.

Other Thoughts: Im having a problem with this PSU. It keeps making noises. Rattling within the PSU. Then its coming out through my speakers. When i disconect the speakers it comes out the PSU instead. I think I will have to RMA this. But I will have to pay for Shipping.

4 out of 5 eggsDOA =(

Pros: Cheap and does its job. what more can you ask from a PSU.

Cons: 20+4 mobo cable is a little short, Could be a pro if you have a small case!

Wires unsleeved! makes everything a pit of a mess and doesnt look all that awesome. But if you are planning on re-sleeving Your PSU it wont matter.

Other Thoughts: Came DOA, and I wont get a replacement in time for the rebate so I'm not keeping the drive. But I wont mark it down for that, computer parts come DOA, its just part of life, Newegg customer service was awesome to me so its not a big deal.
