Wanting to upgrade a ProDesk 600 G3 MT

@raynebc,

Excellent news!

Here is a 942332-001 with a "P2" 7-pin, 6-line with 6+2-pin PCIe power cable purchase option via eBay (best price I could find) -if I may: New For HP PA-3401-1HA 942332-001 400W 280 288 480 600 800 G3 G4 Power Supply | eBay

Kind Regards,

I coincidentally bought one of the PSUs from that auction a couple days ago and it should arrive sometime next week.  Thank you for recommending it.

The ASUS GTX 1660 I bought seems to be taller than the card in your thread, to the point that I can't insert the drive bay tray.  I could use metal shears or something to cut it up, but it will require a bit more modification than yours did.  Luckily it looks like there are two different 2.5" rails I can use, and the upper one could stay intact after I cut out some of the middle of the tray.

@raynebc,

Yes, used shears as well to install the Dell Nvidia GeForce GTX 1660 Ti 6GB GDDR6, but eventually -because I installed the oversized CPU heatsink/fan combo, I removed the drive bay tray altogether:

This desktop has three drives: two M.2 NVMe SSDs (one is installed in the M.2 NVMe SSD slot, and one in the PCIe x4 slot using an M.2 NVMe SSD to PCIe adapter), and one SATA SSD which is Velcroed on top of the power supply. Btw, upgraded the "G3" motherboard with a "G4", and installed an i7-8700K, plus installed an RTX 3060 12GB GDDR6 card. UserBenchMark scores: HP ProDesk 600 G4 MT Performance Results - UserBenchmark, and filled the optical drive "gap" with an ODD bezel cover: Re: Upgrading to an HP ProDesk 600 G4 MT - HP Support Community - 8610054.

It took longer to find my aviation snips than to cut up the drive bay insert, but the snips made short work of it:

@raynebc,

Well done! -Everything working A-OK?

I'm still waiting for the correct power supply to test everything out thoroughly, but hopefully soon.

Would there be any significant hit to the video card's bandwidth/performance if I installed a PCIe x4 card to add an NVME for more fast storage?

[NonSequitur777]

@raynebc,

No, there wouldn't be any significant hit on your graphics card's bandwidth/performance. I imagine you want to use an M.2 NVMe SSD adapter card in the PCIe x4 (the white) slot for this addition?  Also, the number of PCIe lanes your motherboard supports (16 lanes) only has an effect on the speed the data gets sent from the CPU to your graphics card. Not on how fast the graphics card performs by itself.

You are good to go.

OK, I just wanted to make sure I didn't cause a problem.  The Sabrent PCIe to NVMe adapter I'm looking at (https://www.amazon.com/Sabrent-NVMe-PCIe-Aluminum-EC-PCIE/dp/B084GDY2PW) is physically sized to fit in the other PCIe x16 slot (for added stability) but is defined as only using 4 lanes and looks like it is keyed to be able to fit into an x8 slot or an x4 slot.  My use of the secondary x16 slot won't halve the bandwidth available to the primary x16 slot (where the video card is) simply for plugging in an PCIe x4 device, would it?  Or would it be better to use the x4 slot specifically to avoid problems?
