    I purchased this after my power supply was hit by lightening. (surge protectors are not guaranteed against acts of God) It is made for a slightly larger system than what I use. It works well, there are extra cables if I expand.

    I bought this to resurrect an old PC just to stream movies and music. It won’t win any flashy awards and you’re not going to run a beastly gaming rig on this thing but for General home use it’s been very reliable.

    When you need a replacement power supply, it is very convenient to have a local Best Buy and pick one up that same day for a reasonable price.

    Only needed it to see if the older one was getting bad or not. Turned out to be something else. Going to keep it as a backup or for someone else who may need it.

    This was a quick removal and replacement of my computer power supply after it died when we had several power surges in a very quick span of time. The new unit fit perfectly where the old one was and had all the connections where I needed them. It also looked much nicer in appearance than the original unit.(wires wrapped in bundles, looked cleaner). Good unit at a good price.
