Nvidia graphics adaptor

I am sure this has been asked a thousand times in one form or another but I have not found what I am looking for.

I have an HP Z230 XEON with a NVIDIA K620: (Specs Below)

Running SKP 2020

I want to upgrade to a new NVIDIA card with at least 4 gig ( more if I can afford it) .

I went to NVIDIA and a host of other web sites to find out what is best for cad and 3d modeling but it is quite a maze to figure out what is best and compatible.

PS is 400 watts.

Can anyone guide me to a chart or recommend a card.? I want to keep cost $500 or less.

Thank you

NVIDIA Quadro K620
Manufacturer NVIDIA
Model Quadro K620
Device ID 10DE-13BB
Revision A3
Subvendor HP (103C)
Current Performance Level Level 0
Bus Interface PCI Express x16
Temperature 42 °C
Driver version
BIOS Version 82.07.7a.00.13
Physical Memory 2047 MB
Virtual Memory 2048 MB

That is a serious limitation. Looking at what a local computer store has to offer, I find that the GTX 1650 is their only model with PSU recommendations under 400 W. The PSU recommendations of the RTX models start from 500W. The 2650s have 4 gig and cost less than half of your $500.

Make sure that the new card fits in your computer case - the K620 is a low-profile model, as far as I understand.

Is that a PCIe 2.0 slot? If so that limits what you can get. Perhaps a GTX 5xx series?

Since posting the reply below I found this online tool, Pretty handy… Has a basic and advanced mode.


Actually my PS is only 320 watts so I would have to upgrade it just to get 400 which I think is the largest I can put in this machine…
I found this:

NVIDIA Quadro P4000 … I think the 400 watt PS should be ok as long as the card is 150 watts or under ??? What do you think??? maybe the QUADRO P2200, only needs 75 watts

My machine is the Tower workstation

Its going to be over 500 bucks though unless I can get a good used one if there is such a thing as a good used one.

I stopped using Quadro based cards years ago when I noticed that my GeForce card at home ran AutoCAD and SketchUp just as well if not better for less money. Perhaps some others will chime in on their experiences but in my opinion you will not see a vast improvement with a high priced quadro.

I totally agree.

@ACVMF, I wouldn’t bother with upgrading the PSU to get in a slightly faster GPU. Your best option, I think, might be to get a GeForce GTX 1050 Ti for something like $100 (it is an outgoing model, so an “outlet” price)

For the price of a P4000 card plus your other upgrades you can buy a complete “gaming” computer with a RTX card that is faster than the P4000. That is what I did last winter when the age of my Quadro 1800 was starting to show.

Thanks both of you…

I did some reading about recommended cards for SKU and see Gaming and CAD/3d modeling have different demands. Seems the gaming cards are faster but don’t perform in other areas best for a workstation, namely precision vs speed. I don’t play games on my machine so I want the best performance for graphic design and 3d modeling. I ordered a 400 watt PS so after looking at the specs on hp.com for my machine I should have no trouble with any card that is under 150 watts.

This is not my area of expertise at all so I am listening to you…

What do you mean by this? Nowadays when everything about a display is digital, the make of your graphics card has no effect whatsoever on what your pixels look like on your screen.

The electronics inside a GeForce and Quadro cards are virtually identical. Sometime more than 15 years ago Quadro cards had available different optimized drivers for commonly used CAD applications like AutoCad, but today all those are discontinued (perhaps not for high-end systems like Solidworks or Catia).

This is, again, a thing of the past. When I bought my overpriced Quadro 1800 card I had the small benefit of avoiding a couple of irritating bugs that plagued SketchUp users with GeForce cards under Windows 7. Problems with OpenGL support in GeForce drivers seem to be history now (knocking on wood).

I don’t play games either.

I agree with Ansi. I am running an Nvidia GTX 650 ti on a 4th gen Intel core i5 while I am working from home on a Dell Precision T1700 (a workstation) with no issues what so ever while doing AutoCAD, SketchUp, Adobe Suite, Fusion 360 and Simlab Composer. I have a new Dell Optiplex at woth with a 8th gen i7 and an Nvidia RTX 2080 running the same programs including Revit. Again, no issues at all. The biggest waste of money in my opinion is buying a Xeon/Quadro based system for normal CAD/3D work.

Get a physical measurement of the existing power supply. Compare that to the specs of a 600 to 750 watt unit. Most of the units in this range are the same physical size.

Might need this…

For review…

I think I had to buy one of these 24 to 18 pin jobs for my Precision PS upgrade.

Something else to consider: the newer video cards require power connectors either 4, 6 or 8 pin from the power supply. Check the cable configuration.
