Dell G5 5000 PSU Upgrade

Hi all,

Just a quick and simple question - I have a Dell G5 5000 desktop with the 360w PSU, I'm wondering if I can upgrade it to the 500w PSU so I can upgrade my video card. I know both PSUs are proprietary to Dell, so PSU upgrades are limited to Dell products, but I can't find pin specs for either anywhere, so just curious if it's as simple as quick swap or if it's not possible.

Thanks!
