your power supply might be too "small", but some high quailty power supply can handle these much stuff. eg the last "server box" I built has a Dual-300w power supply (hot swapable, you can pull out one while the server is on, and nothing will change), each single 300w unit can handle a 1Ghz intel cpu + 4 SCSI HDD in a mobile unit (with a huge fan) + RAID SCSI card + NIC + 4 case fan (2 x 9cm, 2 x 12cm) + ATi AGP card (common for server, same chip integrated on many server mobo) + a CDRW drive + floppy drive. but I still recommend you get a better power supply unit, at lease 300w.
