Hi friends, today I had opportunity to make some measurements for my own. I hope some of you might be interested :-) My system: Cube 450 MHz - 1,5 GB RAM - 60 GB WD-HD Graphics: ATi Rage Pro 128 (=original) - GeForce 4 MX (without fan!) - ATi Radeon 8500 Mac Ed. Display: Formac Gallery 17' ADC I tried several conditions and noticed the power consumption. Cube with GeForce 4 MX ______________________ & Formac at ADC: OFF 9,5 Watt without Formac OFF 8,3 Watt with Formac SLEEP 10,5 - 12,9 Watt running, without HD read/write 59,8 - 60,5 Watt with HD read/write up to 68,9 Watt read/write from DVD-R to HD up to 73,7 Watt Cube with ATi Rage 128 ______________________ running, without HD read/write 59,8 - 60,5 Watt with HD read/write up to 68,9 Watt Cube with ATi Radeon 8500 Mac _____________________________ cause this is a card with DVI/without ADC, it is run with Dr. Bott DViator, that means no power from the cube, just signal Cube OFF 8,3 Watt SLEEP 9,5 Watt running, without HD read/write 44,1 - 44,8 Watt with HD read/write 51,2 - 54,1 Watt Unfortunately the the fan of the Radeon 8500 is relatively loud. My conclusion: Using the cube with electrical support of harddisk and DVD-R could give me ca. 10 - 15 Watt, may be the ADC is without effect on the DV-Board (?) But another case than the origin is necessary. Nice weekend Stevie
