Just bought the MB and CPU combination above. It came pre-configured with fan from the company. Installed in case with 200W power supply and it would not fully power up and would just shut down. Looked at the documentation, which said it needed at least 230W, preferrably 300W PS. I bought a case with 300W PS and installed the MB/Chip and all other necessary hardware. I checked the power up process after plugging in each board and hooking up each drive. Everything was fine. Even installedWindows XP Home Edition with no problems and set up several users. It had been powered down and up several times during the install process. Turned off the machine and moved it to another room in my house so I could get to an internet connection.It then started with the same problem as before. Turn on the power, the Chip fan comes on briefly, then everything powers down. Anyone have any suggestions? Thanks in advance for the help.
