    I purchased this power supply as an emergency replacement when my main computer went down. The old power supply still ran but dumped the ability to send signal to the video card. So far it has performed perfectly.

    I wasn't sure if my older computer would work with this, but it powers my new graphics card just fine. Simple set up but make sure to mark your connection points on your mother board before removing the old cables!

    This is for your basic desktop computer, not for a gaming machine or editing machine if you are seeking plentiful molex and sata connections. Power is strong and build quality feels solid.

    I needed to upgrade my power supply because my old one wasn't compatible with my new video card. This one has a good amount of voltage and should work for most computers and graphics cards.

    The first one I bought the 400 watt was not strong enough. The 2nd one was a 520 and was just what I needed. It has no power switch that threw me off but works fine.

    easily fit in computer as replacement, only issue was there were many more connectors than the power supply in the computer and not all the connectors matched

    This was a replacement for a faux power supply in my computer. It provided the correct number of power connectors and worked as advertised.

    This Insigna cable is better that the one Samsung provides with the Note 3. I would recommend as a spare or replacement.
