    Good product, worth a purchase

    Posted by: from San Diego on 03/27/2013I've used this for a couple years, and it's done well. Runs a Phenom quad-core gaming computer effectively. After a couple years, it is now making a grinding sound, but it does not seem to interfere with its function. I will be purchasing another, and I recommend that you purchase one too. Good value, good quality, decent life.

    Posted by: from Yakima, WA on 02/09/2013I got this power supply for around $55.00. Big upgrade over my 400W that died. Very easy to set up an install. The extra cords were the only thing that I had an issue with. A great value.

    Good for certain applications

    Posted by: from Long Island, NY on 01/21/2013I bought this Dynex power supply to upgrade a PC that I was installing a new video card on. The video card is a NVIDIA - GeForce GTX 550 Ti and required a 400W power supply according to the Best Buy website. I purchased this Dynex 520 watt power supply and thought that should be fine. Upon installation of the power supply and video card, anytime the video would start working hard the computer would crash and go into a safe mode. The power supply just couldn't handle it. After further review of the video card's requirements I realized it could run on 400 watts but needed much more amperage. The Dynex was not up to the task. Not that there was anything wrong with the Dynex, it just didn't have the amperage I needed. That said, not many power supplies do. I had to step up and buy a Thermaltake SMART Series 850-Watt ATX Power Supply to get the amperage I needed. So the Dynex is a fine power supply. Just be sure you check your amperage requirements as well as the wattage requirements. The amperage specification isn't mentioned very often in product descriptions or specification requirements. Check with the manufacturer of your components for the exact requirements before buying a power supply. I figured it out after reading the specs on the Nvidia box. The amperage requirement was not published on the Best Buy website where I purchased the video card.
