Have Duron 1200+ with 768 sdram and on board graphics and lan and such . Will a 230 watt power supply run this with out problems mobo is a m810LR7 PC-Chips (which i know is junk) but have this setup in another computer and thinking about updating it and put old stuff in another comp for a back up.
I set up a MATX motherboard with onboard video, sound and LAN and a CDRW and floppy drive in a POWMAX case with a 230 watt PSU. And 256 MB of 2100 DDR. I only have used it as an experiment and it has never crashed and I played Soldier of Fortune on it a little bit and it worked fine. I would not plan on adding any other hardware to this computer without changing out the PSU.
Wattage load calculator This site has a calculator to determine the load the components in your system will put on a power supply....hope that helps answer the question.........
