No 5v in new PSU power to CPU lead. Where can I get it from?

[Coupebuilder]

Im replacing a burned up NX-3000 300w power supply in an older CNC Plasma that uses a Pentium III processor. The old PSU had a 5 pin plug carrying (2) grns (2) 5v and (1) 12v to the CPU connection. I realize 4 is normal but I can jumper one...however my new Corsair 750 modular unit only features twin 4 pin plugs with (2) grd and (2) 12v connections. Where can I pull the 5 volt from or do I need to find a different power supply? The Peripheral cables with 3 outlets could be jumpered but already all three sockets are in use and I feel its asking too much to pull more from it or am I overly concerned? First post and ty for any help!
