    This was a good upgrade to the fan that we had. More powerful and much quieter than the old one.

    After reading the many reviews on power units the Insignia™ - 520W ATX Power Supply seemed to fit my requirements. Prior reviews noted that it was loud so I am not complaining since I was warned. I have gotten use to the noise but if I had it to do over I would spend a bit more money and get a quietier paowr supply.

    An intermittently bad power supply had been giving me years of trouble with my desktop computer. Finally! when it got replaced with this power supply, no more crashing & now reliable service. Not expensive & reliable power source, definitely a good purchase.

    VERY easy to install. Provided plenty of power for all of my devices. My older computer had been failing and sometimes "drawing down" because I have so many USB devices running at one time. The salesman pointed out the selection of power supplies and this was was priced in the middle range and had a great wattage level. Installed in 5 minutes and my computer is working great now.
