Parmenedes Posted September 10, 2020 Share Posted September 10, 2020 (edited) Hi, I'm planning to get the EVGA RTX 3080, and it requires three 8-pin connectors. Will my RM850x handle this ok? I'm pretty sure that 850 watts is plenty of power for this card (along with an i9 9900k cpu), but I'm not sure about the connectors themselves. The RM850x has five 8-pin outs on the unit, but I don't know if they all deliver the same amount of power, or if some of them are designed for other stuff. Am I ok connecting any/all of those 8-pin outs to the new GPU? Edited September 10, 2020 by Parmenedes Link to comment Share on other sites More sharing options...

All of the 8-pin outputs on the PSU are the same and do the same thing and deliver the same voltage and are capable of outputting the same amount of current.

Parmenedes Posted September 11, 2020 Author Share Posted September 11, 2020 One more question: Are the PCIe cables that come with the rm850x bi-directional? I ask because the 8-pin PCIe cables that came with it have an extra 6-pin connector hanging off of one end, and I'm wondering if I can plug that end (the 8-pin part of that end of course) into the power supply so that I don't have to see the extra connector hanging out in my case near the GPU. Incidentally, I do also have an extra 8-pin cpu cable that came with the PSU. The connectors look exactly the same as the PCIe cable (without the extra 6-pin hanging off of one end), but I'm guessing I shouldn't use that for PCIe since it's labelled for CPU?

No. They're not keyed the same. Incidentally, I do also have an extra 8-pin cpu cable that came with the PSU. The connectors look exactly the same as the PCIe cable (without the extra 6-pin hanging off of one end), but I'm guessing I shouldn't use that for PCIe since it's labelled for CPU? The only thing similar between the CPU power and the PCIe power connectors is they're both 8-pin. The polarity is reversed and the keying of the connector is different. Please only use cables as they are intended to be used. Link to comment Share on other sites More sharing options...
