Product: HP Z400 Workstation
Operating System: Microsoft Windows 7 (64-bit)

I have a Z400 i need to upgrade PSU to around 850W. I tried installing 2 graphics cards worked great for 10 mins then slowed down to a crawl. I read that the 2 GPU's in crossfire use 450W on there own the stock PSU is 475W I belive the unit has to be able to power a server MOBO.... not sure....Ideas?

Hi @400workstation,

 

Using 2 Graphics card will consume more power. For Z400 power supply info, you may refer to below link for more information.
