You need three +12v wires to feed a PCIe 8pin. The two molex to PCIe 6-pin only provides power from two.

This, plus you would want all 3 of those wires coming straight from the PSU, when in this case they're likely going to originate from a single wire, and PCI-E power wires are usually thicker than what you'd find going to a molex connector, to cope with the extra current that the device would be pulling down. Highly do not recommend.

Just get the appropriate cable.
