upgrade EliteDesk 705 G5 Small Form Factor

[diolula]

Good morning,
I would like to upgrade the graphics card of my EliteDesk 705 G5 Small Form Factor.
Could SAPPHIRE TECHNOLOGY AMD Radeon RX 6400 (4 GB) be a good solution?
Are there any problems with the power supply?
Are there any other graphics cards you would recommend?

Thanks for your suggestions

@diolula,

Welcome to our peer-to-peer HP Community Forum!

An RX 6400 has a 53/55-watt TDP. It appears that your 180-watt "platinum" power supply should be able to power an RX 6400 like this HP EliteDesk 705 G5 SFF User shows.  Make sure that the Sapphire card's dimensions (LxWxH) are a fit for your case.

Unfortunately, I could not locate a power supply upgrade for your desktop.

Don't bother with any other graphics card such as a GT 1030, as it will not be a graphics upgrade.

Kind Regards,

I installed the SAPPHIRE TECHNOLOGY AMD Radeon RX 6400 graphics card and it fits, unfortunately the power supply is not powerful enough. Can you recommend me a 350W or higher power supply that I can install on EliteDesk 705 G5 Small Form Factor?

Thanks!

@diolula,

I dug deep trying to locate any power supply upgrade for your HP EliteDesk 705 G5 SFF -but again, I could not find one unfortunately.

Speaking of your Sapphire RX 6400, there are a number of its users who claim that this card runs well with a 180-watt power supply:

Not sure what to recommend.  For all intents and purposes, there really should be a power supply upgrade for your desktop -but it is exceedingly elusive.

When the card is installed, the pc fails to start. The same happens if I try to start the pc without a graphics card. The PCI slot works, because I installed another card and everything works correctly. I suspect it might be the defective graphics card. Tomorrow I'm looking for another pc to test the graphic card. In the meantime, thank you very much!

You will need a small low profile card to fit in that case preferably one that is powered only from the PCIe unless you wanna make a PSU that will independently power the GPU only

I installed the graphics card on another PC and it works.

Unfortunately I am increasingly convinced it is the power supply: when the card is inserted the power supply fan starts and stops, starts and stops...

The worst thing is that from the reviews that @NonSequitur777 showed me, for other people everything works perfectly.

Does anyone have a suggestion?

My PC is an HP EliteDesk 705 G5, AMD Ryzen 5 Pro 3600, 16 GB RAM, 512 GB SSD.

Is there an alternative power supply for this case?

Thank to all

Just make an external PSU for your card like the good old days of 3DFX
