5 out of 5 eggsGood Out Of The Box

Pros: Plenty of power for a simple build.
Enough headroom to support muliple drives and a discrete video card or two.
Large cooling fan.
Very quite.

Cons: The wires coming out of the power supply to the connector were intertwined. That shows poor workmanship at the factory.

Other Thoughts: This is the first PC I built in 6 years. Prior to that I built well over 2000 units; had a computer shop. One thing that always hold true is the weight of the power supply. This one does indeed feel like it capable of 600 watts. Back in the early to mid 2000's most PC.s were using 300 to 450 watt power supplies; a little more for highend gaming systems due to the graphics card. Back then computer shows were still around with vendors selling 500 watt power supplies for 1/2 of what I could buy a 300 watt power supply. And guess what; they were also 1/2 the weight.
When choosing a power supply its important to figure out how much power you need and if you plan on adding devices later on. A mATX system with: onboard everything, 1 hard drive, and 1 optical drive is not going to draw much. A 300-350 watt power supply will work fine; just look at what the tier 1 OEM's are installing. Notebook power supplies are in the 80 watt range and will run the laptop and charge the battery. In my opinion, there is no reason to overspend on a power supply; buy one that is 20% greater than the maximum power you'll need for now and in the future.

3 out of 5 eggsYou get what you pay for.

Pros: It was cheap. That's really about it. Fast delivery but that's more due to Newegg than the PSU.

Cons: It's loud as hell. Looking through other reviews it seems to be really hit or miss as to the noise level of these units. It just hums really loud, doesn't exactly sound like the fan, but I'm not entirely sure either. It's definitely the loudest PSU I've had, and I've had quite a few over the years.

It has a strange smell to it, which I figured would go away after a few days, but now a week or so into owning it whenever I power my PC up I get this strange odor. I've dealt with PSUs that die out and emit a electrical burning odor, It's not that, at first I just thought it was that "brand new factory smell" that you get sometimes but now I'm not so sure.

Other Thoughts: Yeah, essentially you get what you pay for. I don't usually buy PSUs just because they're cheap, but my old one died on me and I didn't want to wait a month for my next paycheque to come in before I was able to use my rig. That being said, I really feel like I wasted money here, and wish I had been able to afford another $30-$50 for a proper PSU. Don't buy this unless you're really broke and just need something to get your rig working. I'm going to be purchasing a new PSU within a month or two just because I don't trust this thing in my computer, and because It's loud, and the strange smell it gives off.

4 out of 5 eggsEasy RMA on a decent PSU for the money

Pros: Inexpensive and even though I got a PSU that went bad, the RMA was extremely painless through Coolmax. I emailed the details and was issued an RMA number same day. I had to pay to ship the defective one to them, but they literally sent a replacement the day after receiving my old one. The new unit directly from them works flawlessly and is super quiet. I'm glad for the 2 year warranty.

Cons: I had reviewed this originally as 3 stars and I'm rating this at 4 to up it to 3.5 total due to my RMA experience. This unit is fine for a low end to moderate build as long as you get a good one. I got a DOA unit from newegg and returned to them for a new one. It worked, but I knew it wasn't quite right as it made popping sounds whenever it was turned on. I probably should have sent it back too as when 10 months later I went to move it to a new case and it never started up again. So maybe they are very easy to break in shipping or something.

Other Thoughts: Once you have a good unit, it works well. I run 2x HD 6790s and a athlon 651k overclocked on it just fine. I was kinda peeved at the second unit i had dying, but I'm wondering if it wasn't just the shipping that messed up the first two units. Coolmax RMA process alone makes me want to increase my rating of this unit. Its so hard to find companies these days that won't try to find a way out of their warranty. THANKS Coolmax!

5 out of 5 eggsOne year later...

Pros: Bought this just over a year ago, reviewed about a month later. See the third review on this product for my first review.

Still working great, now powering a GTX 670 instead of a 7770. Still putting out great power, still working fine.

Cons: Nothing much, as long as you're not expecting anything fancy from this PSU. It works, and that's all you should expect from it.

Other Thoughts: I know that I'm not big on buying brands that I don't know or trust, but this turned out all right in the end for me. Never had heard of Coolmax, but it turns out they can make a decent PSU. If you're on tight budget and need a good amount of power for a low price, this might just be the power supply for you.

3 out of 5 eggsWorks, but stay under 400 watts!

Pros: Cheap, SLI and Crossfire ready

Cons: Doesn't put out anywhere close to 600 watts...

Other Thoughts: My system works fine with this power supply with a single 6770 card. Total system watts figures out to be (with max rating used) to 317. Add one more 6770 at 108 watts and this power supply is done. So it seems that a 600 watt power supply cannot handle 425 watts.

5 out of 5 eggsRuns Like a Champ

Pros: I have have had no issues with it. Installed without a problem and fired right up when I turned the PC on. Runs nice and quiet, had to pull the tower back out of the desk to make sure it was even running it was so quite. The fan on my GFX card is louder then the fan on this.

Cons: I have had this for almost a year now, and I have not had any problems with it.

Other Thoughts: I purchased this in June of 2012 before it had any reviews on it. Was worried about doing that, but figured I would take a chance on it for the price. When I installed it, I made sure that I switched it off with the on-board power switch. Once I had it fully installed, I plugged in the power cord, and I then flipped the on-board power switch on. Didn't have any issues with it. It fired right up when I powered the tower on.

5 out of 5 eggs4 months, no problems

Pros: Quiet, no chirps or sparking noises, seems to be holding up well.

Cons: None that I've witnessed, but it does have a slightly higher price tag. Seems to be worth it so far, we'll see how the company service is when it breaks.
