@Cris: It's not he 5V rail, it's the 5VSB (standby) rail. All ATX compliant power supplies do this.
@Frankino: That's also been discussed again and again and again. If you cut the +5VSB rail going into your motherboard, then it will pull PSON low which signal sthe PSU to turn on. The solution is to use a relay to break the 5VSB and PSON signals whenever the PSU and your ignition is off. If you really want to save time, read the thread, implement the solution, be happy.
The Opus 90W and M1 don't have this problem because they can be jumper configured to disable the +5VSB rail. The M1 however has a very minimal 12V rail. I doubt it will be able to power your Athlon XP based system.
