Posted August 31, 2022 Country: norway Hello. Do i realt need to have 3 pci-e cables in my rtx3090 asus Strix oc. Or can i use 2 pci-e cables and 3 8pins. Thats 500w. My power supply only had 2 pci-e cables, and can i order one more psu that is just the same and use one of thats pci-e cables if i realt need 3 pci-e? Powersuply i have now is a Cooler Master V850 SFX Gold. i guess i cant use 2 psu in one pc so many i gang use the cable from the second psu in the first? Do i make sense?

Posted August 31, 2022 If you have a extra cable that is compatible with the V850 you're fine. I wouldn't recommend running the graphics card with only 2 PCIe power cables. Other than that the only thing I can mention is that 850W is right on the edge of what I would consider "good enough" for a PSU that is powering a RTX 3090. If you experince sudden shutdown without warning, it might be because you are tripping the OCP in the PSU. This can only be fixed by getting a more powerful PSU. Please mention or quote me if you want a response. ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ Link to comment Share on other sites More sharing options...

Posted August 31, 2022 Your powersupply should have four pcie 6+2 connectors according to their specifications. If you lost the cables that came with it you should be able to order the replacements from the company.

V850 SFX Gold 850W Full-Modular 80 Plus Gold SFX Power Supply | Cooler Master As far as I can tell, the PSU in question only comes with 2 PCIe powercalbes with 1 6+2 connector at the end. So the best solution would be to buy another cable. I found these cable on Cooler Masters store, but I am unaware of which is the correct one for the V850 SFX (don't know if it uses type 1 or type 2 cables): https://store.coolermaster.com/eu/pci-e-8-pin-to-2x62-pin-modularflat-cablemodel-1 https://store.coolermaster.com/eu/pci-e-8-pin-to-2x62-pin-modularflat-cablemodel-2 Please mention or quote me if you want a response. ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ ¯\_(ツ)_/¯ Link to comment Share on other sites More sharing options...

I was sleeping. I have now idea of its a type 1 or a type 2. Maybe it si written in the manual. If i dont find anything there, i will buy one more Cooler Master V850 SFX and use one cable from that. So glad i dont have to buy a new case Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
