I have just bought a couple of DIGN HV5 cases from Japan, its a smart aluminium case. It has one major shortfall; it only has space for a Micro ATX PSU. I'm trying to build a powerful system, using an Asus P5GD2 MB, Corsair XMS2 5400 Pro Dual Memory (1GB), 400GB Serial ATA HDD, Serial ATA Plextor DVD, Intel P3.2GHz Processor. All build and ready to fire up, however the system manages to stay on for 10..20..30 sometimes 40 seconds then powers down. The motherboard has a 24Pin PSU connector and the Micro ATX is 20Pin, I have converted it with an adaptor but it doesnt make any difference. I would consider an external PSU, could anyone recommend any?????
