My boss has an HP z200 workstation that he bought about 3-1/2 years ago (now out of warranty) that he runs SketchUp on. Some of our models are running slow and I wanted to upgrade his video card. The only downside is the PSU on the z200 is a 320W proprietary psu (non-standard-ATX).

The system specs are:
CPU: Intel Xeon 3440 Quad-core 95W
RAM: 4x DDR3 1333 ECC 2G
1x SATA HDD
1x DVD-R/RW multi-drive

The PSU output specs are:
-12V - 0,15A
+12Vsb - 1,3A
+12,1Vcpu - 16A
+12,1Vmain - 16A
+12,1V1 - 16A
no listing for +5V or +3.3V

Any thoughts on an upgrade to the ASUS 7750 (no external PCI-E power needed)?

Here's a link to the ASUS video card -> http://www.asus.com/Graphics_Cards/HD77501GD5/

Yes, if the PSU does not matches with MB (I mean connectors) then there is nothing to do but to stick with HD 7750, unless he agrees to upgrade to a complete new PC. And yes HD 7770 uses a 6 pin connector which I forgot to mention.

Technically the GPU needs very little power to run so a 320W will work. But its better to have a PSU of a rated brand like XFX, Corsair, Seasonic, of 500/550W. It not the power consumption only, you need clean supply to protect the components. So its better to upgrade a PSU at first place.

Measured power consumption R7750
1.System in IDLE = 155W
2.System Wattage with GPU in FULL Stress = 188W
3.Difference (GPU load) = 33W
4.Add average IDLE wattage ~10W
5.Subjective obtained GPU power consumption = ~ 43 Watts

You can even run a HD 7770 :

Measured power consumption R7770
1.System in IDLE = 155W
2.System Wattage with GPU in FULL Stress = 231W
3.Difference (GPU load) = 76W
4.Add average IDLE wattage ~10W
5.Subjective obtained GPU power consumption = ~ 86 Watts

Thanks for the answer, lonewolf7.

I totally agree and had actually purchased a Seasonic x650 Gold to replace the old PSU with and an Radeon HD 7770. However, the z200 uses a proprietary psu which is larger than a standard ATX and the motherboard 20-pin connector is non-standard either (I just found this out when trying to install today).

Just wondering if I should recommend he get a new computer or go with the HD 7750.
I was only thinking of the 7750 as it uses less power and doesn't require external PCI-E power (just uses power form the PCI-E bus).

Custom adapaters can be made that will mate a standard ATX power supply connector to a proprietary mother board connector. . .

[see the reply by GeorgeBurgess, who reports having successfully made and implemented an adapter for his HP z200, and who offers his services for a small fee]

In a similar vein, some owners of consumer-grade Acer & Gateway desktops have been dismayed upon discovering proprietary connectors inside. . .
