[Net]

from the specs: http://www.amd.com/us/products/desk...5870/pages/ati-radeon-hd-5870-overview.aspx#2

the Maximum board power: 188 Watts

if i overclock the 5870 but run it at stock voltage will it not go over the 188 watts?

A bump clock frequency will increase the wattage by a small quantity. A bump in voltage will increase wattage by a large quantity, even if the clock frequency remains the same. Higher wattage, higher temps
