  • ramborobert,

    You could give a single RAIL PSU a shot. If you have at least 24A on the 12V RAIL it would eliminte the PSU as your problem.

    Take Care,

  • Buy the Enermax EG465AX-VE(G)(FMA) 460W ATX1.3 Power Supply from http://www.overclockers.co.uk/acatalog/Enermax_Power_Supplies.html

    I bought for my other PC and it has 33A on the +12V rail. At £35.19 it's good value.
