Powermac G4 MDD ATX Power supply conversion


my friend bought powermac g4 mdd 867mhz. not power on, light on power button goes on short time goes off. told him replace pram battery has not worked.
have deducted must power supply issue. not pay £65 used replacement of ebay have looked modding atx power supply fit.
if understand correctly need atx power supply of around 400w, , 20pin 24pin extension cable prevent ourselves cutting power supply cables.
cut pins match mdds pinout. (diagrams on website)

correct.
advice appreciated! power light comes on short time may not power supply issue advice on other possible issues (apart pram battery) fantastic!
