Hey, recently the power supply on my workstation blew out and the motherboard on my other computer as well, so i decided to combine them. The problem is that im not sure if the power supply in the working computer is big enough to handle all the components. The specs are: P4 2.8ghz (either northwood or prescott), 1gb ddr (433mhz), 160gb Sata, 120gb Ide, nvidia 5500 gfx card, dvd-rom, dvd-rw. The power supply is a new Antec 350. Also, i hear a very highpitched noise coming from the computer, could this be the power supply straining?
