I don't know the exact current draw of my A3000UX (CSPPC, Meditator, etc). But, with just the computer and all 12 hard drives spinning, the UPS of course running, and all sitting idle, it makes the 'lectric meter spin faster than 2 Sparcstation 20's with an equal number of hard drives. My A3000UX is also a source of heat. It keeps my office warm on the coldest days, honestly!
