Windows 7: PSU advice

Even the fastest HDD will not saturate a USB2 interface, so you will not get any benefits from connecting it with a USB3 cable. In addition, although the USB3 sockets will accept USB2 cables as well as USB3 ones, the same is not true of the reverse, so it is extremely unlikely that a USB3 cable will fit your external enclosure anyway.

Assuming that you do have an enclosure that accepts a USB3 cable, you still won't get an increase in speed when using a HDD due to it being an electro-mechanical device. For that, you require an SSD, and even those will not saturate a USB2 interface (although they are getting closer).

Also ensure any PSU you buy has at least 2 12V rails. I had a 600w ezcool which had only 1 12v rail and it failed big time as it couldn't supply the necessary amps. I now have an OCZ which has 4 12v rails each supplying 18A giving me 72A in total whereas the excool could only manage 25A with the same wattage. Amps are far more important these days.
