So I got a new graphics card in the mail today,i ordered the graphics card wednesday and ordered the power suppl sunday. So the graphics card comes,i stick it inside of my computer fits fine,turn it on and it comes on. I noticed some odd things,it didn't need that power supply 6pin thing inside of it to run it just turned on by itself. I stuck my finger inside of it to see if it was on and it cut me. So i unplugged it went downstairs and got a band aid. But when i turned it on again it didnt do anything,as soon as i stuck my finger in it it stopped moving so i guess that was the problem. I moved it a little bit and placed it back in. Then it just sounds like its about to explode,like a very large fan about 100x bigger then the small fan. The power supply I have is very cheap and is 200W...Is a 430W Corsair Power supply the minimum or the required power supply to have for this graphics card. My graphics card is a MSI Nividia GeForce GTX 650 OC 1GB. Thanks guys!
