Almost Caught My Computer on Fire

ByBrianon April 13, 2014

Size: 500 WattsVerified Purchase

NEW updated review. Almost caught on fire... yes you read that right. I was woken up one night to a SUPER intense burning smell from my office, and I thought someone was having a campfire outside. After checking around the room, I smelled my computer and the smell was coming from it. After powering it down, I smelled the fan at the back of the power supply and the smell was intense. I couldn't believe it, I'm glad I was home. I'm glad I could turn the computer off and salvage other pieces from it. But yes, after less than a year, this piece of equipment almost burned my computer literally.

Original review: This power supply was bought after the one in my quad-core desktop went out one day. Plugged it in, got everything wired and its been humming along ever since. Works great, no complaints!

Better than advertised.

ByJohn C. Storeyon April 23, 2016

Size: 600 WattsVerified Purchase

I had this PSU in my computer over the course of a variety of upgrades since I bought it. New video card, new motherboard, more memory, 2 more hard drives, several more fans, etc.
My computer's load went from about 500w to about 750w and this thing endured. When I went over its recommended capacity it already had some age on it. I ran my 750w system (based on newegg's calculator) with this power supply for at least a year of gaming. By gaming I mean 3d graphics and my load increased because I put a video card that permitted me to run everything on ultra. So I basically put as much load on this PSU as I possibly could.
Mine died and I took it the case off of it to see if I could tell why. There was a part that was visibly expanded and a clump of dust right next to it. So I suspect that the PSU did not quit from wear but actually from that clump of dust shorting something out.
If you are building a system on a budget with upgrades planned in the future, from my experience, this thing is a great value. It will likely outlast and outperform your best expectations.

Power

Works great with; my NVidia GTX 560 Ti video card (according to NVidia, required at least a 400W power supply), my Intel 2nd generation i7 2600K 3.4 GHz processor, and my corsair vengeance 8GB DDR3 memory cards

Unreliable: Died after about a year and a half. Cooler Master would not honor warranty.

ByJack of Tradeson November 23, 2014

Size: 500 WattsVerified Purchase

I purchased this in 2013 and was happy while it worked (would have rated 5 stars). However, over a month ago, it failed. I contacted Cooler Master and was happy to find out the Warranty would cover replacement for the PSU. I paid about 15 dollars to ship the PSU to Cooler Master's HQ in California, and after about a week they sent Email confirmation that my RMA was received. 2 weeks past and I heard nothing back from them and sent in a support ticket and talked to a live representative who promised to find out what was going on and E-mail me. My support ticket was ignored and was automatically closed by the system, and I never received an Email from the person I spoke with. I have since filled out additional support tickets and now after nearly a month there is still no replacement for my part.

I can no longer function working through other computers, and am forced to purchase another Power Supply Unit form a different company. I Will Never Again Purchase a Cooler Master Product. I am so disappointed with this company that I use to have a lot of faith in.

RS700 : Can't power up an HD7950

ByAutoManon June 13, 2013

Size: 700 wattsVerified Purchase

I had used a coolermaster 550W power supply for my system three years ago and it did work perfectly without any issue with a HD5770 video card.
so I thought that a new coolermaster psu would be a good idea, but when I updated my videocard to an HD7950 I thought a coolermaster RS700 could
power the new system but it didnt..
It worked well for 10 days but then,the hard disks failed to boot the OS an sometimes the fans didnt start.

I have changed to a new XFX PSU using the same motherboard and I dont have any trouble now
Its a pitty this PSU dont have enough power for the new cards, so be very carefully if
you think in buying it for a new system.
Look for XFX/Seasonic PSUs or other coolermaster models.

Good Price, Good Product

ByIkerryon March 22, 2013

Size: 600 WattsVerified Purchase

I purchased the 600W over the 500W to go with my Gigabyte Radeon 7850 video card for a gaming computer and couldn't be happier. I easily replaced the old 250W psu from my Lenovo K410 desktop with this psu. It has plenty of power cords with it. Initially the fan on the psu was making all kinds of noise. I set the computer on its side to check it out and the fan all of a sudden became quiet. I set it back upright and now it is soooo quiet its unbelievable. I give it 4 1/2 stars only because of the initial noise of the fan. It is handling the 7850 with ease. Great gaming set up. It's so quiet I can hear the keys on my keyboard as I type this. I highly recommend this psu and the price is competitive as well.

A Good Bang For Your Buck

ByJonathan Jungon April 20, 2016

Size: 500 WattsVerified Purchase

It's a great PSU. I've had it for 2 years and it hasn't given me any problems since. Very quiet and very cheap. Does its job. The only reason why I gave it a 4 star is due to it's design. Yes, it's cheap and there's no reason to expect many things from this PSU but it does serve its purpose. If you don't have much money, I recommend buying this PSU.

Not so quiet, but it solved my problems

ByThe TechnologistVINE VOICEon November 22, 2012

Size: 500 WattsVerified Purchase

My 10 year old desktop, which I built myself started to freeze, shutdown and was becoming just unreliable. I did a little research and noticed that the voltage that the machine was getting was just all over the place, so I knew it was time to replace the power supply. The Cooler Master was in the price range I was willing to pay for such an old machine (especially with the $10 rebate card), plus I put in the 500w, which was more than the original Antec True Blue 430 watt already in place. Installation was a breeze, just a matter of looking what you unplugged where and plugging the same plugs on the new power supply after you mount it up. Mounting is easy, just use the included screws and line them up with the mounting holes in your case. The power supply appeared to solve all of my issues. Since its installation my computer is running fine, and the voltages are exactly where they should be. I hope this power supply lasts as long as my original did, it seems pretty rugged, so it has a shot. The fan on this drive is slightly louder than my previous power supply which had both a rear mounted fan and a downward pointing fan. It's not "super silent" as the manufacturer claims.
