Question Add 2nd GPU to HP Z600?

[kamorrissey]

I have an old HP Z600 dual-Xeon workstation I'm not ready to retire that I use for Blender modeling and renders. It currently has a GTX 970 GPU that has served me for years. Can I add a GTX 1650 to this rig for simultaneous use? It's only 75W with no external power. Is that too much for the 650W PSU if I'm also using 2xXeon 5650 for rendering? I'm not sure how to estimate the wattage of full CPU and both GPUs and whatever other power overhead there is.

If it's too chancy, I'll wait till I can afford a newer workstation.

How old is the PSU in your build, at this point? If it's the original PSU from 2009 that the prebuilt came bundled with, then you should avoid adding anything further. even if the PSU was brand new, I'd have suggested something that's not a multi GPU rather, the single most powerful GPU that your wallet might be able to handle. The other thing is that your platform would be best off being retired if you need to look at a more powerful GPU.

It still has the original PSU. I won't try doing any expansions on this workstation.
