    Took my computer in. No wait. Guy figured it out right away. Put in new motor. Done and finished in less than 30 minutes. Plus being a member of Geek Squad was a money saver.

    If you need a cheap but effective power supply in a pinch, this one's great. 20-24 pin connector, 4-8 pin board power, pcie 6 prong connector, powers most mid range video cards.

    Instructions were clear, it did take a little bit of reading. Make sure you mark or take pictures of what you take apart so you can make the correct connections.

    Nothing to report other than it does what it is supposed to do. Needed a new power supply for my wife's computer - Geek Squad recommended this one, and it works as described.

    Our computer wouldn't power up and Best Buy checked it out and found it was the power supply. They directed me to this unit and I had them replace it instead of doing it myself and they did it right away and I was able to go back in a couple hours and pick it up. The unit is working great and they did a good job. They explained everything involved and I was very happy with their service. Nice job Best Buy.

    I bought this as an open box item at a really good price. Had an older computer that used IDE and ATA drives that got zapped with a power surge. Fortunately the PS took the hit and the motherboard was OK. This PS had both connections and worked fine. Not tons of power but unless you are running a high end CPU and graphics card there is plenty of power for what ever you need.
