I had a TurboLink LC-A350ATX 350 watt power supply in the system listed in my sig. I had a 250GB SATA drive, two 40GB EIDE drives, an LG Electronics GSA-4040 DVDRW drive, a Zalman 5100 CPU fan, and a Turbo Cool DC 12V case fan installed in the system as well. Also the Radeon 9800 Pro Ultimate 128MB uses the same kind of power connector that IDE drives use. Everything was fine for a couple days. I surfed the net, let it stay on overnight while I downloaded stuff, played Half-Life, but then I loaded up Halo (final) with all the fixins at 1024x768 and that worked great for a few minutes. Then my PC turned off and I think I smelled fried circuitry. I can not get the system to power on at all. I tried taking the PC to another outlet, taking out all hard disks, using different power cables but still I push the power on button and nothing happens. Was the system underpowered? Would that cause my power supply to fry? How many watts should I go for in this system bearing in mind that I plan on adding a PCI ATA/133 controller, another 250GB SATA, a 120GB IDE, and a 250GB IDE drive later, in addition to the 3 hard disks that are installed right now? The A7N8X Deluxe v2.00 board has the ASUS CPU Overheating Protection, so that probably means my power supply is fried and everything else should be OK, is that correct? Any recommendations for anything I should do?
