3 Things to Know About the HP ProDesk 600 G6 SFF Power Supply
Regarding the HP ProDesk: 1. The power supply is proprietary and not user-serviceable HP uses a built-in 180W or 260W 80 PLUS Gold unit that cannot be swapped out for a standard replacement.
Upgrading to a higher wattage later is not possible The PSU is locked into the chassis, so you cannot increase power capacity down the road for a more demanding GPU or other components.
Order the right wattage from the start If you plan to add a low-power GPU or other power-hungry parts, choose the 260W option at purchase, because you will not be able to upgrade later.
