i've been noticing that my pc seems slugish and not running how it should (at least i think). my current setup is... ASUS P4B533-E i845E P4 (Northwood) Skt478 DDR ATX Motherboard Pentium 4 2.26 533Mhz Northwood 512 DDR (forget the speed) Nvidia Geforce 4 TI4600 Sblive 5.1 Plat Pioneer DVD-ROM Plextor cdrw Sony DVD-(+)RW and currently powering 5 hard drives. now my question is i have a 330W power supply. am i under powering my pc? would this be one of the reasons for such sluggish performance?
