Hi All, I'm having weird USB problems on my main server. ... What I'm assuming to be power related - Just want a second opinion b4 I go out and buy a 425 watt PSU one. . . PUS - Generic 300 Watt Motherboard - Genuix XI Processor - 2 PIII 500's with active cooler Video - ATI 2000 Network - 2 3com, 1 intel (onboard) Disk - SCSI 10k Seagate & 1 Maxtor D740X, 1 52x CDROM Fans (excluding CPU & PSU) - 2 x 80mm YS-Tech & 1 x 40MM generic on SCSI disk cooler. What happens is. . . . From boot up everything is cool. . . USB works, fan work. 5 minutes or so into operation, the USB device dies - NO power to is at all. I have tried using a powered USB hub - same. (that's what confused me - as this is supposed to solve USB power problems. When the machine is under heavy load. . . I can sometimes hear the fan's slow down for a second - is this normal? Opinions?
