I have a fairly proprietary system that is powered by switching PSU that only seems to output 12v. The mainboard has a 10pin header that outputs 12v so you can power PCIE video cards (obviously it's a unique connector, but the breakout cable is a dual 2x3 PCIE power cable). I have no intention on installing a graphics card, instead I'd like to add an SSD and therefore need 5v. I can easily figure out which pins supply 12v and which ones are ground, obviously, but what's not so obvious to me is how to safely step down the 12v to something the SSD can reliably use.
Would something like this work: https://www.amazon.com/NOYITO-Three-Ter ... 66874?th=1 I could of course DIY a similar solution but this is an easy way to convey the idea.
