i decided to swap the power supplies as the antec psu has a higher wattage and the thermaltake psu is much quiter and would suit a HTPC better. after about an hour of attempting some sort of cable management i put my case back together, plugged in my bits, turned on the AC and hit the power button. nothing. i turned the ac off and on and tried again. the cpu fan twitched then.....nothing. i just don't understand. the Antec psu powers the intel pentium system absolutely fine and so does the Thermaltake. but the Antec will not power up my AMD main system at all. i'm completely lost and have spent the last four hours googling and swearing and hoping someone can tell what the hell is going on! Please help!!

i appreciate this but the power supply is working. however it only works with the intel system. it won't even turn on at all in the amd system. i have checked all plugs and cables numerous times and the amd system is functioning but only using the thermaltake power supply
