I have an M92p with an I7 3770 with upgraded 400watt psu and a GTX850M(I know the best they say you can get is a 1650 because these GPU's dont have a 6 pin..).however the upgraded psu has multiple sata leads that I can buy a 5 dollar adapter for and make them power supplies for a gpu. Does this mean I could find a more powerful gpu that requires a power supply as long as it will fit physically in the case? Or will some other reason prevent it from working? I'm probably gonna have a i7 6700k in about a week and either way I'm trying to find a gpu that won't bottleneck the CPU or vice versa. Thanks
