Is it possible to use a standard AT (old style) computer power supply just for its +5v out? I have a project and I just need 5v with a beefy amount of amps, and I have lots of AT PS's around that would fit the bill, but I'm wondering if running a computer PS just for its 5v line might damage it somehow? There would be no load on the 12v (and other) lines. Anything I should worry about?
Thanks!
