Some as noted at http://www.tomshardware.com/answers/id-2302723/elite-desk-800-psu.html are proprietary and not upgradable.
Hello everyone, first thank you for just taking the time to read this. I have a hp elitedesk with an i7 and purchased a 1060 6gb gpu, I had to upgrade my psu turns out my original psu has a 6 pin connector instead of the 24 pin connector. So my new psu doesn't have that connector, it goes on the motherboard on a slot called pwrcmd p2. I did see some adapters online but theydont have the same colored wires. What can I do? thank you!!
