Hello I just bought a HP - ENVY 700 Desktop http://www.bestbuy.com/site/hp-envy-700-desktop-12gb-memory-2tb-hard-drive/8997042.p?id=1218968345257&skuId=8997042&ref=06&loc=01&ci_src=14110944&ci_sku=8997042&extensionType={adtype}:{network}&s_kwcid=PTC!pla!{keyword}!{matchtype}!{adwords_producttargetid}!{network}!{ifmobile:M}!{creative}&kpid=8997042&k_clickid=7bf2d0b4-1ecb-9869-5345-00004846fc60



and i put a gtx 660 sc into it. its pretty quite, until i load up a graphically intensive game such as bf3. I am SURE it is not coil while on my gpu or psu. it makes a hissing sound like blowing air through your teeth :( help please!
 
I am sure the stock PSU is nowhere near powerful enough for a GTX660, considering it only came with integrated video. Assuming you haven't already killed it, you'll need a PSU upgrade for that card. On a budget, an Antec VP-450 would do, or a 450W Rosewill Capstone.

Well evrything runs fine and the psu is 460 watts so its more than what you suggested. the minimum for gtx 660 is 450W
