PSU +5V Problem

I just finished building a new computer yesterday, but the PSU seems to be giving me problems. The BIOS shows that the +12V and the +3.3V readings are adequate, but the +5V has a reading that tends to hover around 4.5V which, according to what I've read, is extremely low.

I understand that the BIOS is not an accurate source for PSU readings (and I have yet to use a multimeter, though I am going to try that next), but I can't imagine that the BIOS differs from the actual readings by such a large amount.

I am hoping that I won't have to return the PSU (if that is actually the device that is causing the problem), so I am just wondering if there is anything that I can do (as a novice at computer-related issues) that would alleviate this problem.
