HP ProDesk 400 G4 Microtower Power Supply upgrade.

HP ProDesk 400 G4 Microtower
Microsoft Windows 10 (64-bit)



Just bought a HP ProDesk 400 G4 Microtower that I thought I change in to a gaming pc.

My plan was just to put a EVGA GTX 1050 TI SC in there but I ran into some problems.


I saw that the power supply was only 180W, and there is a 310W version of that same power supply. 

And I know to run the 1050 TI i need atleast 300W.


Does anyone know where I go from here?

Do I buy a completely new power supply from another company? Does HP sell the 310W?

And I saw that the motherboard dont have 24 pin, is that going to be a power issue? 

Please help.

@Ref_UG, welcome to the forum.


Here is the Maintenance and Service Guide for the workstation.  On Page 129 there is a section for the power supply unit (PSU).  It doesn't give any maximum power requirements.  However, I believe that the 310W PSU is maximum.  Also, on Page 16 it has a list of compatible Graphics Cards.  Normally, workstations aren't built for gaming.
