How to properly upgrade to a better GPU? And some PSU wattage help.

[AntDeek]

Just do it.

Edit: There's always a chance that a proprietary system such as yours does something that we can't expect. But it should work.

Edit2: Went looking for that PSU. It appears that it comes with a 6 pin PCI-e connector. Link

Actually, Its an odd design where the 6 pin plugs directly into the motherboard, and the motherboard has connectors for HDD power, so that is not a GPU 6 pin, that's a motherboard 6 pin since theres no ATX 24 pin.

But thank you, I am buying the ASUS GTX 950 tomorrow!
