What are you doing with said GPUs? Folding 24/7 on them or what?
Per Nvidia's documentation, at stock, each:
-GTX275 has a max power draw of 219W
-GTX460 has a max power draw of 160W
If we *assume* that each card is at stock at that power draw and going 24/7 all month. These are worst case assumptions based on known data...That ends up being ~550kWhrs of electricity per month (0.760kW*24*30). The key being what a kWhr costs
What does a kWhr of energy cost where you live? In California, rates can be nearly $0.50USD per kWhr...in NoWhere they are as low as $0.06USD per kWhr.
At $0.50USD/kWhr. That ends up being $270USD of electricity per month.. At $0.06USD/kWhr only $33USD per month. For all 4 GPUs going full bore 24/7.Edited by Skripka - 5/18/11 at 1:12pm
