@Sajin,
It was just for a test, I agree with you... I still would like to know, if I were to use the correct EVGA cable, would I have any issue connecting two GPUs (rx 470s) or one Vega from the single port?
Thanks!
Two rx 470's off a single cable? Yep, as long as you're running the cards at default settings it should be ok. A single 6-pin is rated at 75w, but has a maximum power-handling capability of 192w. Based on
this review you'll be pulling 88.1 watts per card from the pci-e cable, and 54.9 watts per card from the motherboard pci-e slots, so your total power drawn would be 176.2w from just the pci-e cable alone, and 109.8w from the pci-e slots. PCI-E slots can provide a max of 75w each.
A single vega 56 off a single cable? Yep, it should be fine with the card running at default clocks on the secondary bios, and the turbo power profile selected. A single 8-pin is rated at 150w, but has a maximum power-handling capability of 288w. Based on
this review you'll be pulling 18w from the motherboard pci-e slot, and 210.3 watts from the pci-e cable itself.
A single vega 64 (air cooled) off a single cable? Yep, it should be fine with the card running at default clocks on the primary bios, and the balanced power profile selected. Based on
this review you'll be pulling 24w from the motherboard pci-e slot, and 260.6 from the pci-e cable itself.
Note: For safety purposes I would recommend using separate cables for each gpu as the last thing you would want to do would be to fry your hardware from running things over spec.
