  • Rated 4 out of 5 stars

    Did the job but hate the cables

    This is supposed to be a small form factor power supply. Then why are the cables so long?! Used this in a Silverstone SG05-LITE case and the cables were too long. Also, multiple connects on 1 single cable. Makes it difficult to have a clean build. Ordered custom shorter cables from cablemod. The cables are my only complaint. FYI, I am absolutely no expert! I know just enough to get myself into trouble.
