Hello!
I've been having trouble with my HP computer and it seems like the PSU has been acting up. I would like to replace it. Does anyone know a good PSU for my computer? it's Windows 7 - Nvidia Quadro 4000.
Thank you in advance

i recommend posting workstation models (like your z400) in the workstation forum
have you done the power supply "BIST" test? if it passes chances are it's not the source of your problems unless your overloading the power supply by drawing more wattage than it's rated capacity
