PSU Replace 12-pin with 8-pin cable

[Indeec]

Hello! I have a Enermax Modu87+ 500w PSU, Lepa g500-ma 500 is rebranded modu87+. I need to connect 2x6-pin video card. Unfortunately I have lost 12-pin to 2x(6+2)-pin cables, but i have 8-pin to 2x(6+2) cable from another PSU (Chieftec GPA-500C). Can I use this cable instead original 12-pin cable? Are they compatible? Shape of connectors is the same. Is there any specification for modular PSU connectors? Thanks.

PS I have seen this theme http://www.tomshardware.co.uk/answers/id-1977154/psu-pin-pci.html. But I have another question.

You should never use cables from a different brand of power supply.

Two different OEMs using different modular panel connectors and pinouts would tell you no.

Thanks, I will use 2xSATA(Molex) to 6-pin instead non original cable.
