No it does not but not all Rosewill power supplies are reliable as far as brand goes no that is not how you pick a power supply IMHO anyway.Because as much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have an or several dedicated video card(s). As a general rule of thumb, you are aiming for the highest number on the 12V line.
