Think you know your power supply requirements? Have a go at this then A friend has tonight been playing with a plug in power meter to see what the computer he's playing with pulls from the wall. He's running a 990FX-UD7 with an AMD FX-8150, 16GB DDR3, 2x 6990s, one mechanical HDD and a 1200W 80%+ gold PSU His first test was running BF3 on ultra with everything at stock. What do you think he saw the meter peak at? He then OCed the CPU to 4.4GHz with 1.5Vcore and ran Furmark's burn test along with Superpi 32M. Again, what do you think he saw it peak at? Finally, with the CPU still OCed but just sat idle on the Win 7 desktop (all power saving features off) what do you think he saw the meter read as the peak draw? Unfortunately I don't have pics of the results but do know them so will reveal them after a few days of guessing. I do reckon most will be surprised though.
