5 out of 5 eggsWorks Well

Pros: Runs cool, Quiet

Cons: None

Other Thoughts: Used in a moderate system build (Athlon x2 250, single Nvidia GeForce card) for over 3yrs, no problems. Maybe others are overloading thiers?

3 out of 5 eggsRan great for 3+ years

Pros: Quiet, easy to clean, enough cords and cords are long enough. 3 years of working

Cons: Died with a very loud bang pop and sparks. Took out my mobo, ram, and harddrive. CoolMax very quickly sent out a replacement. The replacement seems to lack the power and causes resets.

AMD FX-8150 8 core

Other Thoughts: It lasted for 2 and a half years with my original setup

I upgraded and it died after six months. After getting all my parts warrenty replaced the system has random resets. I replaced the video card with a less powerful card. (one that doesn't need the 2 6pins) The computer now runs without resets. I give it 3 eggs for the 3 years it worked but I would still suggest getting something a bit more powerful for components build in 2012 on.

1 out of 5 eggsIt exploded.

Pros: Worked for the first year or so I had it.

Cons: PSU started running hot. Then, in the middle of a game of Team Fortress, it freakin' exploded. Loud, dramatic pop noise. Burning plastic/magic smoke smell. I don't have a backup PSU so I'm hoping it didn't take any other parts with it. Do yourself a favor and buy something else, I'm not the only one in this review section that had this happen to them.

3 out of 5 eggsExplosions O.o

Pros: Plenty of power for my gaming rig (quad-core AMD processer, 4gb RAM, GeForce 450 GTS).

Cons: After owning this PSU for 3 years, it literally exploded on me during a gaming session...

Other Thoughts: Hopefully, I can get it replaced via warranty claim with Coolmax.

1 out of 5 eggsWill never purchase from this company again

Pros: Kinda worked for a while?

Cons: After MAYBE six months of use, the fan made an AWFUL sound. It was so loud I could be three+ rooms away and still hear it. I called Coolmax, and they did not want to work with me at all. They told me I could send it in, and it would take a minimum of two weeks before they could even LOOK at it, let alone send me an RMA unit! I explained that I was using this in a server environment (gotta love desktop-servers anyway =/ ) and waiting around without any PSU was not possible. I was essentially told they don't care. I couldn't even pay to have them send a new unit, and then have them refund the money once they received this one.

Other Thoughts: It happens. DOA reviews don't scare me because every product spanning every manufacturer will have defects from time to time. It's when a company has a very blatant disregard for their customers that I get weary. This is one of those reviews. This company did not care that their product failed within the first six months. Choose wisely!

3 out of 5 eggsCheap PSU. Good for non gaming computer.

Pros: Lasted me 2.5 years running a AMD quad core system with a HD4850 GPU.

Cons: Cannot handle an AMD HD6870 GPU

Other Thoughts: Blew up today (literally blew up) after running for 6 months with an HD6870 and 2 Hard Drives

5 out of 5 eggsNot As Bad As Everyone Says

Pros: More than enough power for a modern mid range gaming rig

Cheap

Has lasted me 3+ years with constant heavy use

Cons: only 2 pcie

Other Thoughts: I've been running my i7930 with turbo on (3.1GHz), 6gb ddr3 1600, 1TB HD, and a 9800gtx+ for a couple of years. I wanted to pop in a 560ti to crank up the graphics on swtor, but I was concerned I would have to upgrade my power supply, considering the person below me said it wouldn't power their 6870. I took a chance knowing I would probably have to upgrade and bought an EVGA gtx 560ti 2gb. It's been running swtor quite beautifully for a week now with about 8 hours a day of play, no hiccups. I'm not claiming this power supply is on par with a corsair or seasonic, but it does get the job done and at a very reasonable price. I got mine at *fry's* a few years back for $35. Don't be deterred by other reviews, this power supply will easily run most mid to upper range gaming rigs. I'm tempted to throw in a gtx 580 and report back.
