3090 extra 8pin power help (ghetto rig)

[OpenLooper]

So im that guy who gets a 3090 and forgot about getting an extra 8pin for my modular psu (850w corsair).

Could this ghetto rig work?

Step 1- Two molex to 6pin:

Step 2- 6pin to 8 pin converter

What you think?

Thank you

those 2x6>1x8 adapters are awesome for starting fires.

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.

Never thought I’d see 3090 and ghetto in the same post but you have succeeded. Congratulations on your accomplishment.

From my experience, they're pretty shitty at starting fires. Much more reliable ways to do that.

Probably shouldn't do it either way though.

Not enough RGB. Needs more tbh.

No tape, no foil, no tie wraps? Needs more work, tbh.

Glad you got it sorted.
