According to Corsair's website that PSu has 4 PCIE cables: http://www.corsair.com/en-us/cx-series-cx850m-850-watt-80-plus-bronze-certified-modular-atx-psu-na

A Rx 570 shouldn't have more then 1 PCIE plug.... if you have a model that takes 2 I suggest selling it and buying a different model. Wink You should be able to run 4 Rx 570s with that single PSU that you have already.

Hi thanks for the reply,

I have (850w):
Corsair CP-9020099-UK CX850M
https://www.amazon.co.uk/gp/aw/d/B00P2GDQZ8

I also have (650w):
Corsair CP-9020098-UK
https://www.amazon.co.uk/gp/aw/d/B00PGUSEBG

And I have ordered (1200w):
Corsair CP-9020070-UK
https://www.amazon.co.uk/gp/aw/d/B00SGW51I0

If possible I want to be able to power up to 6 cards, although I don’t think this will be possible?
I can overclock and undervolt - although I don’t want to do that until the system is set up.

Many thanks,
Tim

Could you post the exact model of Corsair PSU you have? Unless it's a really old model I think all 850 watt PSUs would have more then just 2 PCIE connectors.

As for using 2 ATX PSUs together the best option is to buy an add2psuadapter for $10-20 depending on where you buy it.

Hi all,

- I have an AsRock H81 BTC pro motherboard (mobo)
- A Corsair 850w psu and a Corsair 450w psu.
- 2 RX570s (each require 1x 8pin & 1 x 6pin power connectors).
- I have many powered usb risers.

I currently have 1 GPU connected up to my mobo, have have another RX570 sitting in a box as I am not sure how to power it up.

I am running my system on the 1 x 850w psu currently, which only has enough PCIe connectors for 1 GPU?

I am going to order a couple more RX570s if there is a way to power them?

I am more than happy to buy a better PSU etc but I am not sure which one / how to?

Any help I’d greatly appreciate,

Many thanks,
Tim
