Should your GPU draws 75W or fewer you don’t have to have supplemental electricity in the PSU. Actually, if you have a GPU that’s involving 75W and 120W you’ll be good using the inventory PSU (280W for G2 Minitower).???? ???? ???? ???? ????? ?????, ?? ???? ????? ?? ????, ????? ?/?? ?????, ??? ??? ????, ???? ????? ???? ????? ????? ????? ?????
