After I saw the first couple of messages, I started thinking the same thing. I've seen systems w/ 4 IDE devs. get loaded down. 8 disks plus whatever else on that system is a LOT of devices sucking a lot of power. Dedicate a seperate PS for some of those drives, and see if that doesn't help out. Just saying that its "plenty" w/out trying does nothing to further this. ...and how much "coddling?" Hell....that is a LOT of devices there. You toss that much hardware in a box...you NEED power.

Check with PC Power > and Cooling, SuperMicro, etc. for suitable power supplies. No, 300 watts is plenty. IDE's do not use as much current as SCSI drives and I have run more scsi drives than that on a 300W Power supply. Now I suppose it would depend on the amount of activity and the drives particular sensitivity, but that only makes the case more so in some ways. How much coddling do the IDE's need then?
