Can I utilize both 8 Pin ports on the cx750m for PCIE cables?
Can I utilize both 8 Pin ports on the cx750m for PCIE cables?
Hello everyone! I just received a new 40 series card that needs two separate PCI-E cables to power the GPU. I have the Corsair cx750m, which has two 8-pin ports. Between these ports it mentions "6+2 PCI-E Connector & 4+4 CPU." My concern is whether I can use both ports for PCI-E cables or if one should be dedicated to PCI-E and the other to 4+4 CPU. I’m hoping to be certain before I start using the card extensively.
Thank you for your prompt response and for clarifying the situation. Based on what you described, it seems your PSU is indeed hardwired with the CPU cable. When I checked yesterday, there was only one PCI-E (from an old card) and one SATA connected in a modular setup. It has been used regularly for years in that configuration. Does this align with your understanding?
not knowing the full specs of the pc, it is possible your mobo/cpu combo does not need the extra cpu power. so only what is hardwired is needed. not a big deal if that's all it needs.
some more power hungry cpu's use that extra 4+4 to the mobo to feed the cpu beast. been working as is so no need to second guess it now
so just plug the second pcie power cable in and you're good to go.
upon closer inspection, it appears you already have a 4+4 hardwired setup active on your motherboard. you possess an additional modular cable, but your motherboard doesn't require it—particularly for a 5600x. you're supplying it with more power than necessary. i have a few of these and they consistently handle under 100w in testing; i suspect you might have pushed them to around 125w if you've removed restrictions and allowed them to operate freely.
