I previously gave this power supply, and other CIT psu a good review. Since then I have unfortunately learnt that these supplies are absolutely 100% USELESS for using in a computer that will be used for gaming. You will find yourself replacing it every 6months-1yr and it will undoubtedly occur at a really really awful time.
Save yourself a lot of grief and splash out on a OCZ supply, or similar, instead. It is WELL worth it. The detachable cables on these are also a nice touch in saving space and improving air flow in your case.
If, however, you are just planning on using your computer for general light use (or anything other than gaming) just buy this. It functions perfectly well in the average computer.
