last December I built this rig it was a budget build and i had planned for being able to upgrade in the future. http://pcpartpicker.com/p/6vkKsY the one thing i didn't take into consideration was my psu..
I really don't want to have to get a whole new PSU for the upgrades i would like but i was planning on getting a after market cooler on my CPU so i could do a minor over clock on it. I would also like to add a second Sapphire Radeon 7770 to the build. I wasn't sure if that 500 watt PSU will be able to handle the upgrades. I looked on Sapphire's website at the 7770s and it said the recommended PSU wattage for crossfire 7770s was 600w but I put together all the upgrades and it doesn't even come up to 400 watts http://pcpartpicker.com/user/eboy1997/saved/N9QcCJ I do understand that adding more to a low wattage PSU will make the fan rev up but i'm not worried about noise as long as its stable i'm fine with it. Besides it is a 500 watt PSU I should be able to get 400 watts out of it safely right?

Its not just about Wattage, but rather quality of PSU which is imp when CF is concerned. Sadly, yours is not reliable, even poor, for high loads and not at all recommended for CF of any 2 GPUs. 400W max wattage doesn't mean your PSU will run it. CX are ok to run only if load is less than 70% all the time, or they fail or even explode. Get a good 650W or above PSU, like the EVGA SuperNova NEX 650W. Any 650W+ PSU from Antec/ EVGA/ SeaSonic/ XFX will be good to go :)
