I would advise you to check the HP support site for the HP ProDesk 600 G1 for a list of compatible graphics cards, that will work with your current PSU.įor example, I found this AMD Radeon HD 8490 DP (1GB) PCIe x16 Graphics Card on the list, which is a somewhat decent card, which is guaranteed to work with your system.Īs mentioned in the other answers, trying to get a standard PSU to fit the case/motherboard would be a major hassle. This is clearly not compatible with a standard PCIe 6 pin GPU connector.
I happened to have a HP G600 standing right next to me from a customer, so I took some pictures:Īs visible in the top picture, the blue and purple cables going into the 6 pin plug are not as thick as the other 4, so those would be the ones carrying the power on signal, with the 4 black and yellow ones carrying power.
