QuabbleCrab Posted June 20, 2020 Share Posted June 20, 2020 Hi, i have the old HX650W psu also. I currently have an rtx 2060 using one of the 6+2 pins from the y splitter (i now only have one as i lost the other one). I was wondering if it would be safe to have an RX470 8gb card running off the second 6+2pin connector? People say it should be ok but i also don't understand how? There is a single 6pin going into the power supply and a 6pin = 75w rated. So how can two 8 (6+2) pins power a possible 300w (8pin =150w rated x 2) if those two 8 pins are only running from a single 6 pin on the psu. I know im continuing this thread very late but i would like to know as i have ordered an rx470 and would like to know if i need a new psu. Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted June 20, 2020 Corsair Employee Share Posted June 20, 2020 (edited) Which HX650 do you have? CMPSU-650HX or CP-9020030? If the CMPSU-650HX, that's a REALLY OLD PSU with a very antiquated platform. I would not be using that in a current build. I mean... looks like you have all new parts EXCEPT for the PSU. And where do you get the "300W" number? 6-pin PCIe supports 75W. 8-pin supports 150W. Together that's a maximum of 225W. No PCIe cable is going to support 300W. Also, card tends to use less than 167W: https://www.tomshardware.com/reviews/nvidia-geforce-rtx-2060-ray-tracing-turing,5960-8.html Edited June 20, 2020 by jonnyguru Link to comment Share on other sites More sharing options...
Vegan Posted June 26, 2020 Share Posted June 26, 2020 My R9 Fury is a real 300W card but it needs a pair of 8-pin connectors which needs a bigger PSU than the old HX650 can muster Link to comment Share on other sites More sharing options...
