3 out of 5 eggsOK but has its issues

Pros: The price

Cons: As stated by numerous other reviews, sometimes it will not supply power to fans and your computer will not turn on. When this happens power is supplied to case lights and switches. I have to turn the power supply switch off, wait a few mins, then turn it back on, wait for 10 mins, the turn the case power switch on. Idk why this happens but it seems like the power supply needs to "charge" up before it is able to have enough juice to fully supply my computer components.

Other Thoughts: Since it is cheap, $26 after the rebate, I'll probably just replace it with a better supply if it dies on me.

1 out of 5 eggsDOA

Pros: Occasionally works, and when it does it's fine.

Cons: It's an absolute pain to get this PSU to work.

Other Thoughts: Why 3 months of waiting before finding out it's DOA? I've only just used this PSU today, and it failed (it was sitting in the box for 3 months prior to first use.)

I'm using the provided power cable.

I've tried using it in two different computers, and it's failed on both.
1. G3258 4.6Ghz 1.38V, GTX 650, 3 fans
2. A10 6800k stock, 2 fans
It's definitely not a watt/amp/volt bottleneck issue.

I've tested using a different power cable that supplies the same input amps and voltage as the provided cable, and it works for a 430W PSU but not this PSU.

I've tested with that 430W PSU on both those computers and it worked perfectly, so it's not an issue with any other part other than this PSU.

What'll happen is I'll turn on the computer, and it'll either boot to BIOS right away or will merely supply power to the USB LED-colored/backlit mouse/keyboard. No fans spinning, just LEDs activated. Simply pressing the power button when power is only supplied to the USB devices does not turn off the computer, and I've needed to hold the button to force it to power off, but that takes several seconds longer than it would on a normal forced shutdown.

The only way I've managed to get it to work is to turn off power to the PSU altogether by flipping the switch, waiting several seconds, flipping the switch again, waiting several more seconds, then rapidly flipping the switch 9-20 times before pushing the power button. Silly, right? However, NOT flipping the switch those copious amounts of time only supplies power to the USBs.

1 out of 5 eggsGarbage and No Rebate

Pros: Inexpensive

Cons: Only lasted 3 and a half months before becoming unstable, previously I have bought the cheapest non-certified power supplies over the last 15 years and only one has failed. This one failed in just a few months. Plus still haven't received my rebate from CoolMax!! Rebate form says mailed out 8 weeks after period ends, well the rebate ran through 11/30 and your (coolmax's) site says you received my rebate forms, but now 6 months later still no measly check! Will never purchase a coolmax product again or for anyone I build systems for.

1 out of 5 eggsJunk

Pros: If you're looking to waste your time and money, then this PSU is great for you.

Cons: This power supply is a disease. I bought this "80 Plus Certified" PSU to replace an old one in my home pc and all I can say is this thing is CERTIFIABLY A DISEASE!

You can tell the manufacturing process is really lacking! The cables are all tangled up coming out of the PSU. They didn't even care to untangle them before putting the ends on them!

1 out of 5 eggspoor

Pros: the price

Cons: On start up the fans would turn on for a sec than would turn off, the power supply was shorting out. I ended up going out and buying a corsair 750w and know the pc starts up with no flows.

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.
