The default PSU is 600W
I am running a GTX Titan with the current PSU and would like to install another Titan to do SLI. But the PSU needs to be upgraded, I am looking for 850W with at least 2×6-pin and 2×8-pin PCI-e connector.
Problem is, HP uses a proprietary 18-pin power connector to Motherboard for Z420, whereas industry standard is 24-pin. I can overcome this by using some aftermarket 24-pin to 18-pin adapter
- Can I upgrade the PSU by buying a standard ATX PSU or something else?
- Will a standard ATX PSU fit the cage inside the case?
Appreciate the help.
I take no responsibilty for damage to your HP workstation, but I've seen these around

Don't know if they work or not
