    Was very pleased with the Geek Squad! Brought in my tower at 10:30am and they diagnosed the problem immediately. Installed the new CPU in a short amount of time and was ready to take home around 1PM the same day, did not have to go home and come back another day!! Great job in a timely fashion! Kudo's Geek Squad :-)

    I purchased this at Best Buy when my PC stopped running. After evaluation by Geek Squad, all I needed was a new power supply, and I was up and running. Great price that didn't break the bank. My computer runs quieter than it did before.

    In my business, PC always break at the worst moments. In this case at the end of the day, when you are pass the shipping cutoff time, and nothing will be shipped until the next day. Best Buy happened to have this in stock and ready to go. It was plug and play for a Dell Optiplex 330, everything mounted up perfectly!

    This power supply is low at 300 but it doesn't matter because our servers only air text and some small jpeg photos. Therefore it is all that we need. The two Geek Squad techs installed it within 15 minutes and I was right back at work running everything. Thanks Downers Grove Best Buy!!!

    This unit is replacing the replacement I installed about 2 years ago. It is always running in this DVR PC (in a bank). It is inexpensive and has the right plugs on it, and it installs easily.

    We wanted to upgrade power to drive two monitors and gaming graphics cards. The Geek squad recommended this unit. They were right on target. It has proven to be more than enough power. It easily hands all tasks. Great job, Geek Squad.

    Seems to be a good product for the price. I installed the first on my self and though I had installed it incorrectly, but when checked by the Geek Squad it turned out to be a bad power supply purchased right off the shelf.
