Default Molex to 12V DC Adapter

Anyone know where I can buy a Molex to 12V DC Adapter?
Like the one:

I can't find them anywhere. I made one myself, but the DC wire I used was very low quality and parts of the positive and negative wires were touching, causing it to short out.

I want to use a proper one instead.

You pic doesn't work.

EDIT: I've never seen one of those ever.

I've never seen one either, and I suspect that since 12V DC adapter sizes aren't standard they probably don't exist.

Only thing I could suggest would be to pick up one of the laptop universal adapters for the DC adapter part and then solder the leads from that onto the pins of a molex fan adapter.

I wouldn't suggest such a thing after my experience trying to wire an external HDD to a computer power supply. When I flipped on the HDD the computer would restart (and this was a Seasonic M12 PSU). I'd assume some stuff that accepts a "12V DC" from an adaptor present a load that the computer PSU is not used to, maybe too much capacitance or static electricity from not being grounded properly that make the PSU unstable.

the issue may been that polarity was wrong to restart system or PSU 12v was over loaded by the ext.HDD

add a 2.2k MfD electrolytic capacitor to line watch polarity stripe goes to negative

no problem here doing what SSW said just added the cap for a buffer

mind you my 12v rail has 87 amps yours was 24 amps
