Power Supply options for Z220

[HGNSS_IT]

I have a user that wants to use an nVidia GTX 670 in a Z220 Workstation. I need to upgrade the PSU to at least a 500W.

Can I use any brand PSU, or is the PSU proprietary to HP?

If I have to use an HP PSU, can I use the PSU used in a Z420 (600 W)?

Thank you.

I believe the Z210 power supply is the same as the Z220 PSU in most respects (possibly the Z220 includes some newer low power features which may not exist in the Z210). In any case, the Z210 PSU is a HP proprietary design and unfortunately not interchangable with a standard of-the-shelf ATX PSU....

Also my Z210 PSU is approximately 156x100x147mm (LxHxW) in size while an ATX supply i have lying around is approximately 141x86x152 which means a standard ATX PSU may be too wide to fit in the Z210/Z220 chassis. And then theres the spacing on the mounting holes/screws which are also different between the HP and ATX designs...

Further, the connect wiring is again different with the Z210 PSU having an 18 pin main connector (according to the Z210 Maintenance and Service Guide "pinout" section) while an ATX PSU has a 20 pin main connector. See the the following diagrams for pin wiring of each design (HP & ATX):

Anyway, this means upgrading the PSU in a HP Z210/220 machine using an ATX standard design is not plug and play as there are mechanical fit issues, attachement issues and wiring issues to resolve should you want to go down this path.

And, obviously, HP will not continue to provide any warranty on your machine should you go down this path...

Now the Z220/Z420 Maintenance and Service Guide may still include the main connector pinouts (if HP still provides such info in their docs - they did for the Z210). As such, you may be able to compare the main connector pinouts and determine if Z420 PSU is a better electrical fit into a Z220 than a standard ATX PSU. This should be a simple doc check if the detail is in the Maintenance and Services Guide...

Since i don't have a Z420 system, i can't say if a HP Z420 PSU is the same size or larger than the Z220 PSU so i don't know if the Z420 PSU will still have fit & attachement issues if trying to install in a Z220 chassis... Again this should be a simple doc check but HP does not provide dimensions for the components within a system, though you may be able to infer some PSU dimensions from the Z220 vrs Z420 chassis dimensions, which i belive HP provide in their quich specs...

Good luck...
