Question can one pcie cable handle this gpu ?

[Miragee]

Hello, I need to know if the NZXT C750 Bronze power supply can reliably power an RX6800 when using 2 PCIe connectors through a single cable. When I bought this power supply, I thought that "2x PCIe" in the description meant there would be two cables, but there is only one with 2x PCIe connectors 🙁
Thanks in advance for answer

yes, you can use split cable for rx6800, gpu would utilise just one 8pin, second 8pin is there just for offloading power spikes (stability reasons and to cope with trash psus)

Welcome to the forums, newcomer!

Pass on a link to the card you have. You're advised to have two standalone PCIe cables feeding into the GPU. Daisychaining would be the last resort, actually.

Is one example but Seasonic have one similar to that too.

if this is your PSU and you only have a single PCIe cable, you have the wrong PSU for the job or the wrong GPU for your build. If you're using a splitter off that single cable, you're inviting trouble. Look off the internet and you'll see practically every fire start with a power splitter.

gpu in question is relatively low power for 2x8pins, even on OC edition
XT version on the other hand would be different story
