I have a Corsair CX750M power supply I got used its a modular unit and is missing the 8 pin PCI-E cable. Is there a way that I could purchase one that would work with the unit or would I have to get a SATA or Molex adapter? I have leaned away from the adapter cause I have a 1070 and I don't think they'd have enough power for the card. The Model Number is 75-002019 the Part Number is CP-9020061. I hope the information I have provided can help. Thank you in advance!
