PSU protection with resettable polyfuse

Hi folks, The PSU for my Executel 8085 system is an Astec AC8151-01 40W 5A unit that puts out +5/+12/-12V. A while back somone suggested using an ATX PSU in its place which TBH I'd forgotten about untl I saw a breakout board that you plug a 20 or 24 pin ATX supply into and it terminates each rail
