1 out of 5 eggsDO NOT BUY THIS

Pros: Cheap advertised after-rebate price, good specs in theory.

Cons: There are two major problems with this power supply and one major problem with the company.

The first major problem with the power supply is that contrary to its specifications, it is unable to handle the power surge at boot from even a modest system. It simply turns on and then shuts off. An Intel dual-core, GTX 960, 8GB RAM, 1TB HDD, and DVD drive were too much for it. Unplugging the DVD drive allowed it to boot most of the time. Unacceptable from a "34A" 12V rail. I popped in a spare 350W power supply and it worked flawlessly.

The second major problem is that often, but not always, to boot the computer I need to flip the black switch on the back of the power supply off and back on. Otherwise when I press the power button on the front of the case, nothing happens. Very annoying when the tower is under the desk.

Lastly this power supply is often offered with a rebate, which brings its price down considerably. However, the web address listed on the rebate form does not exist. After manually navigating the website to the correct page that lets you enter your information, it comes up with "server error" displayed on the page and you cannot proceed further. A quick search on Google shows that this problem has been going on for YEARS. A complete scam.

Other Thoughts: Save your money. Do not be fooled by the specs or the rebate. Both are false.

2 out of 5 eggsDon't buy with a R9 270

Pros: -Cheap
-Runs well with a PNY 2GB GTX 650

Cons: Struggles with my XFX R9 270X. I thought i got a bad card but even after they replaced the card, the new card still crashes and i have to reset my PC. Support told me it might be my PSU, so I'm getting it replaced soon.

Don't buy this PSU for a R9 270 card.

3 out of 5 eggsNo Rebate.

Pros: Its a 500Watt that was cheap

Cons: Loud and voltages seem to fluctuate probably will fail if I keep using it.

Other Thoughts: Didn't receive my rebate herd other horror stories about how they ignore rebate letters. Followed instructions to the letter. Principle of the thing is I wont buy another product from them if this is how they go about things they say they are gonna offer and don't

4 out of 5 eggsCoolmax zx-500

Pros: Cheap

Cons: Short cpu 4+4 pin connector (used in an atx build)
Extremely loud fan
20+4 pin connector was sleeved but used a plastic like material and was extremely hard to bend / cable manage

Other Thoughts: It works well, does what it is supposed to and has lasted this long. I would recommend to anyone in need of a super cheap power supply.

4 out of 5 eggsGood-Ish

Pros: Cheap
Quiet Fan

Cons: While the max power rating of the 12V rail is 34 Amps, this PSU doesn't seem to like large inrush current levels. I have a 16 bay 'nas' case that spins up 4 drives at a time with a short delay between, and PSU can't handle it. Yes I am aware that the ultra-nerds would suggest a 1.21GW PSU for this application, but remember that HDD"s don't require much power once they are actually spun up and running. Just be aware that if your system has lots of drives or whatever on the 12V rail, this PSU may not be happy.

3 out of 5 eggsmy least favorite

Pros: Seems to work stable, handling 426W at the wall continuous use (tested about a month).

Cons: I'm disappointed that it did not work using only +12V using popular jumper from green wire to ground. I only need +12 (31A), and even with jumper to override a CPU power switch, would not turn on. I had to draw more power from other rails being waisted just to make it run, costing more per day.

Other Thoughts: I realize the PSU is typically made for standard PC use; I'm not using it for that, so don't be turned off by my review if you're just plugging it in to your computer as intended. It will probably work fine for you and be fairly efficient.

4 out of 5 eggsReliable for money.

Pros: -Has not failed me once.
-Not terrible efficiency.
-Good options for HDDs, GPUs, Molex, etc.
-Keeps relatively cool.

Cons: -Makes noticeable noise. (White noise, not actually loud)
-Like said, not terrible efficiency but I wish I would have invested in a more energy-efficient supply.

Other Thoughts: Good for the money and very reliable.

1 out of 5 eggsNightmare!

Pros: Inexpensive.
Noted in the specifications that it was crossfire ready

Cons: When first installed, it was MUCH larger than my prior power supply, despite being a difference of only 50w. So much larger, that it had to be installed fan side down to fit in the case.
Poorly written manual lead me to spend nearly thirty minutes trying to install the wrong cable to the wrong location. I had to call the company to get that sorted, but the person on the phone was helpful enough.

Things went fine for about 30 days (Funny... just long enough to be outside NewEgg's Warranty!) and I started to get odd shutdowns. I removed a hard drive and a disk drive to see if they were causing the problem. The problem appeared to vanish. I thought nothing of it, until today...

Just shy of 45 days from opening the package the PSU is dead. Not only has it died, but it has dripped some sort of fluid down the inside of my case. I'm not certain at the moment if this is electrolyte from a burst capacitor (in which case I have battery acid all over the inside of my PC) or if this is the fan oil/lube that has suddenly run on the inside of my PC.

I have built my own gaming rig for the last decade and a half, and NEVER have I had this particular problem!

Other Thoughts: Avoid this unit. Unless you enjoy the thrill of waking up to a dead computer and spending an hour and a half carefully cleaning fluid from your mobo and case...
