Connecting a GTX 770 to power supply

[Johnny20270]

Hi, what am I missing here?

I have connected the PCIe 6pin cable to the 6pin slot on the GPU but I get a message at boot up "Please power down and connect the PCIe power cables for this graphic card".

I have a 500W PSU and my old graphics card (Radeon 1950XTX) is working fine on the 6pin PCIe connection


PS: my system is an i7-4770k & 1 SSD, H60 cooler and no other devices so would have though the 500W supply is enough.

Iirc most 770's require 2x 6 pin pcie connectors.

Its a crap one, coolermaster RS 500. Only has 1 x 6pin cable

setter: So as the ASUS GTX 770 has a 8pin and 6 pin connections, do i need to connect to both? I guess I am stuck then?

You can get adapters that convert 2 4 pin molexs into a PCIe adapter. There may be one in the GPU box.

Personally I would strongly advise you to invest in a better PSU.

ok good. Yeah i might just buy a decent PSU. Any thoughts on the correct PSU to buy. I would like a modular one as I have an mATX case

If you are going to stick with a single card then a good quality 500 - 650W will be ample. 750W and over if you want to go with a future multicard setup.
