How's it goin guys, got something I need help with! I recently built my first gaming rig before the release of fallout 4 and realized what I have won't cut it. I currently have a 500W power supply and a Sapphire Radeon R9 270x Dual X GPU. It appears that that alone won't run fallout 4 on ultra settings. So I'm buying an identical Sapphire Radeon and need a power supply that will compensate both. I've been looking at the Cooler Master 750W but everyone says the cables aren't long enough for a full tower. I don't have a full tower but I'm about to buy one too. So is there another power supply you guys think would work? Thanks!
