Better than advertised.

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.

Not so quiet, but it solved my problems

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.

Cooler Master 700 watt power supply

October 19, 2013

Size: 700 wattsVerified Purchase

One of the computers in our house had a power supply failure. I am an advanced computer technician and I am familiar with the various PSU manufacturers. I have used many of the Cooler Master products so when I saw this PSU I knew I was on the right track for a quality product. I did a search for reviews of the Cooler Master power supplies and found many favorable reviews. I decided to purchase this PSU from The Nerds because they had the best price.

My order went smoothly as have all of my transactions I have made with Amazon and their partner sellers. I received communications concerning my order. The Nerds shipped my power supply quickly and it was well packaged. It arrived several days before the estimated time. Installation was the same day and the power supply is working perfectly and has a 2 year warranty.

My experience with The Nerds was a full 5 star transaction. I would recommend The Ners to others and would buy from them again should a needs arise. I will reserve my recommendation of Cooler Master power supplies until this power supply has been in use for 1 year. You could get a DOA power supply from any mfg. I really didn't need 700 watts but chose the 700 watt to have extra power so the power supply won't have to work as hard. I am a satisfied customer as I have been with every Amazon purchase.

Cool and easy replacement!!

December 7, 2013

Size: 500 WattsVerified Purchase

This was a fairly easy replacement for my Dell XPS 420. I had to clean everything after breaking down my pc and had to rearrange my hard drives because of this PSU, but it was easy. The cables didn't reach to to bottom of the case as the previous stock PSU did but that's actually needed because the switch is for housing a new GPU...and it needs to room in my case. It came on with no issues at all. Great buy!!!

**UPDATE**
This PSU has been working like a charm! So far, no problems and it's been 2 months out. I will say this much. If you are looking to expand your system components (GPU, additional ROM drives, etc.) make sure you have enough power. It's not the PSU if your new components don't show up in the bios or in the Control Panel under your hardware devices. You may simply need more power. I found this out by adding a Blue-Ray drive to my XPS 420. It didn't show. I unplugged and additional HDD I was using, plugged in the Blue-Ray drive and viola! It worked!

I've dumped the 120GB drive (only using for small storage jobs) since in already have a 1TB drive installed.
