@OzyDeskTop,

Welcome to our HP community forum!

Yes, this graphics card would work just fine in your desktop.

However, the RX 6600 you referenced has a 132-watt TDP, requires an 8-pin PCIe power cable, and according to the manufacturer requires a 500-watt power supply. According to HP's specs, the stock power supply of your HP Envy Desktop 750-514 (Z5M38AA) is only a 300-watt unit, unless that has already been upgraded -please verify.

So, in order for this card to work, you'll have to upgrade your power supply.  Fortunately, your Odense2-K motherboard is 24-pin ATX-power enabled, meaning, you can use any industry standard ATX power supply, as long as you watch its dimensions (LxWxH) for fit inside your case.

Hope this was helpful.

Thanks.  I don't suppose you could recommend one that would be a decent upgrade but doesn't require the additional expense of purchasing a new power supply?  The issue is that I am using my computer for recording audio and I get some glitching which I have determined is due to the CPU (i upgraded to an i7, and replaced the fan)  being overused.  I've been advised that an external graphics card can help by taking over the plug in activity.

@OzyDeskTop,

Then something much less expensive ($53.76) would be, for example, this GTX 1050 Ti 4GB purchase example: Amazon.com: GTX1050Ti 4GB Dual Fan DVI HDMI VGA Gaming Graphics Card, 128bit, DDR5, 700MHz, PCI Expr....

Thank You, If i decide to go with a more expensive graphics card and upgrade the power supply, i noticed some power supplies say "ATX, PCIe"  if i get one of these that say PCIe  does that mean I don't need an extra cable?  is that the issue?  Other wise i could just get a power supply that just says ATX connector?  Sorry, last question, I promise.

@OzyDeskTop,

Let's give you a show-and-tell example.

This 500-watt ATX power supply purchase option with these dimensions: 150mm (W) x 140mm (L) x 86mm (H) (5.9 x 5.5 x 3.3 inches), will probably fit just fine in your desktop.  It is a 500-watt unit, and it has one 6+2-pin PCIe power rail/cable which you need to power your RX 6600: Amazon.com: ARESGAME AGV Series 500W Power Supply, 80 Plus Bronze Certified, Non Modular Power Suppl...:

Hmm, I replaced the power supply with the 500w AGV Bronze.  That p[art works fine.  I also put in the AMD Radeon RX6600 graphics card but I can't detect it.  I had to plug my screen back into the default hdmi input that comes with the computer to see anything. Any thoughts?

@OzyDeskTop,

This may be too obvious to ask, but I do it anyway: did you plug in an 8-pin PCIe power cable in your RX 6600?

1.) Download the RX 6600 driver from here -don't install it yet: AMD Radeon™ RX 6600 Previous Drivers.

Second, with your RX 6600 card installed, download and run DDU:

2.) Download and run the freeware "DDU" ("Display Driver Uninstaller") program in order to remove your previous graphics card driver. Don't worry, your PC will continue to work/display video. You can download DDU from here: https://www.guru3d.com/download/display-driver-uninstaller-download/: click on the "Download Mirror (USA)", and the zipped "[Guru3D.com]-DDU.zip" file will automatically download. Open File Explorer and click on Downloads, then right-click on the aforementioned file, and select "Extract All...", then click on "Extract", and the unzipped file will appear in your download folder.

Double-click on the unzipped file, then right-click on the "DDU v18.0.7.6" file (or newer version if offered) and select "Run as administrator". It will ask for your permission: click on "Yes", and then on "Extract". Then look for the file "Display Driver Uninstaller", right-click on it, and then choose: "Run as administrator". Answer the questions -don't run in "Safe Mode", choose the default "Options" screen, click on "Close", from the "---Select device type---" choose "GPU", then from the drop-down menu just below it and choose "AMD". Then choose the "Clean and restart" option.

As a visual, here is a YouTube instructional video on how to use DDU (just skip to timestamp: 3:35 because the extra step to run your PC in Safe mode is unnecessary, and it makes this process only more complicated) : https://www.youtube.com/watch?v=xn8z39tiEL0.

3.) Once DDU has done its job and has restarted your PC, go to your Download file, and right-click on the RX 6600 driver and choose "Run as administrator".  When prompted, only choose the "Game Ready Driver".  The actual RX 6600 driver installation will take a few minutes, your screen may flicker once in a while, and your PC may (or may not) restart once or twice.

Hopefully things have improved by now!
