  1. He's correct. The proof is that his system runs fine.
  2. Its fine to run on 4 pin.

    Its even in manual, it tells you what 4 pin holes to use.

    4pin generally is on older PSU's. Or lower than 500W nowadays.

    yeah It was from his q 6600 rig
  4. Is this recommended?Is it ok to game on a 460w psu on a gtx 670
  5. Well I recommened at least a good 550W for that sytem... he might be running on a 460W now.. but sooner or later it wont handle and the PSU will go out.

    He can run on 430W, if the PSU is quality one.

    550W is fine.
