6-pin PCIe to 4-pin Molex

[Ej24]

So I have some proprietary PCIe x1 add-in cards for communicating with a microscope. They require auxiliary power through a female 4-pin molex receptacle on the cards. My Dell OEM PSU only has two spare 6-pin cables. No molex at all. I have some adapters for molex to 6-pin, that is, two female molex and making one male 6-pin, for systems that lack a 6-pin for graphics cards. I need the opposite. One 6-pin female to two molex male. I cannot find this anywhere. Is there a reason for it? Is that not technically feasible? I was just going to make one by switching around the connectors. Is this a bad idea?

molex has 5v and 12v on it, GPU's only use 12v, so if your device requires 5v and 12vt, an adapter won't work.

Unfortunately it's an oem Psu from Dell. They only give you the exact number of Sata power plugs you needs. I guess I could split the Sata into 3 or 4 and then tap into those for Molex?

yup

yup

Cool. Thanks. Glad I won't be feeding a pcie card 12v when it only needs 5v
