Msi z77a-g45 motherboard, intel i5 3570k, thermaltake smart series 750w power supply. I tried plugging it in and it fit. But the question is will it work? lol
if it fits in then it should work, power supply connections are meant to be installed only one way and if it didnt fit then id worry lol, plug in and power up
On new power supply's will be the 24 pin atx cables and one or two sets of video power cables. On most new power supply's there blue and are six pin cable plus two. The CPU power block on a mb can be four or eight pins.
On new power supply's there an be one four pin cable...two for pin cables that lock together or one welded together eight pin black cable.
