Can power supply fuse (F12.5A) be replaced wih a 12A fuse?

The F12.5A ceramic fuse for 700 watt ATX power supply is blown, I think it may have been because of an accidental short. I have searched widely and although different sites list the fuse, no one has one and seem to indicate that the fuse is no longer produced. Would a 12A fuse work or is that half amp a deal killer? The load would be MB, 3 HD, 1 optical drive. Video would not be a gaming one.

Yess O.5 amp lower is acceptable, make sure to test fuse by checking its continuity through a tester meter always before installing it.
