Quad G5: Actual Power Consumption
I haven't seen the numbers posted, so I thought I'd share from this config:
Quad 2.5 Ghz G5 (Rev A, dual pumps)
4.5 GB PC2-4200 RAM (4 x 1 GB, 2 x 256 MB)
Geforce 6600
Western Digital 250 GB SATA Drive (WD2500JS)
Seagate 400 GB SATA Drive (ST3400832AS)
No firewire or USB devices connected (except keyboard, mouse)
Here was the measured power consumption (in watts):
455 Peak measured (with 4 CPU's at 100%, disks writing)
275 Idle (CPU at Highest)
245 Watching a DVD (CPU at Automatic)
210 Idle (CPU at Reduced)
43 Mac Sleeping
The specs page lists "At least 10A" required at 120 volts. Even if you squeezed 9 drives into the G5, I don't see how one would ever approach 1200 watts.
I use a Belkin 1500VA (830 watts) UPS, which is 55% loaded when the Quad is at its peak, and can sustain that for around 10 minutes.
At 7 cents per kWh, running BOINC could cost 77 cents per day, running idle would be 36 cents, and sleeping 8 cents.
