Hey all. I recently bought a new computer from cyberpowerpc and the graphics card in it is less than desirable. So now I'm upgrading from a GT 610 to a GTX 550ti. I have a 500w power supply which seems to be sufficient for the card. The GTX 550ti requires a 6pin connector, which my psu lacks. The card comes with a double molex to a 6pin adapter but the issue is that my psu only has 1 free molex. My question is if I buy a molex splitter will that single molex acting as two work with the 6pin adapter? Or will it be too much on it?
