yes you ill be fine with an 800watt PSU and you have plenty of headroom to overclock other parts on your computer :)

thanks it's very reassuring lol i was a little confused as to how i work out my power usage :)  i have found a thermaltake website which is perfect and it says i use around 400W at full load or 100% usage on both graphics card fans and CPU
