COOLMAX ZX Series ZX-600 600W ATX12V v2.2 / EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply

Pros: it works and it dosent make too much noise under stress.

Cons: n/a

Other Thoughts: lets see how long this thing lasts.

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.

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.

Pros: Just got this one, swapped it out with a 350w (why, I had such low wattage, I do not know) and so far it has performed fine. It is much quieter than the previous one, and it fits snugly into the case.

Cons: When I first installed this, there was an issue with my HDD, but I was able to resolve the issue by restoring via recovery image to before the install occurred (always back your things up before an installation). Also, the power chord does not fit very well into the PS unit itself, feeling a bit wobbly and like it could d/c at any moment if it is not positioned correctly. The wires (excluding the main connection to the motherboard) are not held together by anything other than one zip tie per connector, so you should know a little about case wiring to ensure that you keep an organized setup.

Other Thoughts: I have only had enough time to evaluate the physical unit, as well as its visual and audible properties while running. I will be installing a new GPU tonight and will see if this can handle it.

Pros: Newegg took care of me, although I dislike the concept of paying for shipping on a DOA item. Knew that going in though. Would be a good value for a power supply at that price point.

Cons: DOA. No hissing or popping, or anything. Just nothing.

Other Thoughts: I broke my own rule on this. I always tell people "Don't buy power supplies from untrusted brands". I saw this unit, needing about a 500-600W PS for a build, and first thought "It's not Antec, Cooler Master or Thermaltake. I shouldn't trust it." But a friend of mine who builds a lot of PCs looked at my screen and said "I've never had problems with Coolmax, that's a great deal on a PS". So I dropped the coin ($50 at the time), and then had to RMA it. Paid another $15 to ship it back. Since time was a factor at that point, had to go buy retail from brick and mortar store. Found a 600W Thermaltake for $60. Fired right up. So now this $49.99 PS has cost me north of $75. Will not recommend this brand to anyone, and my buddy that DID recommend it now owes me a steak. Maybe I'll recoup my losses there.

Pros: Nice box

Cons: As soon as I turned it on I heard something short out.

Other Thoughts: Not a good first impression for Coolmax. RMA for a refund. Not even worth getting a replacement. Antec EA380 on the way. Will do what I need right.

Pros: Came in a nice box

Cons: Tested before plugging into PC. Promptly greeted with the magic blue smoke getting loose and that wonderful ozone smell. Never ever hit the power switch before it died.

Other Thoughts: RMA in process. Clear to me that the QC was less than diligent.

Pros: Cheap

Cons: You get what you paid for trash. It says 600 watts it puts out less then 500

Pros: 600w and fairly low cost

Cons: Randomly makes a rattling noise. It drives me nuts when it does it then other times its silent.

Pros: -Cheap
-Works well

Cons: -NOISY AND PAINFUL TO EARS!

Other Thoughts: This is a good psu, but oh my goodness, for some reason this psu makes a screeching noise that kills my ears. I can only run the pc when my noise canceling headset is on. Kind of like nails on a chalkboard when it gets bad. The first one did this, i RMA'd it and now the second one does as well. I would give it 1 egg but it does work well and priced nicely.
