Upgrade GPU for motherboard 8AC1

[DanRotman]

Hi,

I’m looking to upgrade my GPU to the MSI - NVIDIA RTX 3050 GAMING X 6G - 6GB GDDR6 - PCI Express 4.0 and want to confirm its compatibility with my system.

Here are my current system details:

GPU: Intel UHD Graphics 770 (integrated)

Motherboard: HP 8AC1, KBC V12.03.27

PC Model: HP Elite Tower 800 G9 Desktop

Processor: Intel i9-12900 CPU

Operating System: Windows 11

Could you please confirm if the new GPU is compatible with this setup?

@DanRotman,

Welcome to our HP Community forum!

Yes, your HP Elite Tower 800 G9 Desktop is compatible with the smaller-sized (dual fan) MSI RTX 3050 Gaming X 8GB, as long as you got at least a 310-watt power supply, and one 8-pin PCIe power cable.  If you got a 400-watt or 550-watt power supply installed (with p/n: N03175-001 / M86264-001 respectively), these power supplies are equipped with at least one 8-pin (6+2-pin) PCIe power cable.

Most unfortunately, I don't see any purchase options for these power supplies online at the moment, not even via HP:

If you got a 310-watt power supply (open up your PC and look at the power supply's label) without a PCIe power cable, you can use a dual 15-pin SATA to PCIe 8-pin power cable adapter, such as this one: https://www.amazon.com/PCI-Cable-15-pin-Express-Adapter/dp/B07FK8SJTV/ref=sr_1_1?crid=2IVHBIE31FIA0&..., and if it is the case that you don't have two free 15-pin SATA power cables available, you'll also have to buy a 15-pin SATA power splitter cable such as this one: https://www.amazon.com/Mini-Extension-Splitter-Adapter-Chassis/dp/B07M99R88S/ref=sr_1_6?crid=8XBNB0M....

Thanks!
I checked and do NOT have 310W PSU, it's only 260. I would like to also upgrade this and was thinking of something like "Thermaltake - SMART 700W ATX 80 Plus Power Supply". I think it has all the correct connectors but I saw my motherboard has a ribbon cable from the PSU to the PWRCMD area on the motherboard. Do I need an adapter?

@DanRotman,

Interesting: I thought there was a 310-watt power supply, but instead your PC platform only has the 260-watt, 400-watt, and the 550-watt power supplies available:

Since a 260-watt power supply is altogether insufficient to power an RTX 3050, you'll need to purchase either the 400-watt or the 550-watt power supply.

Unfortunately, there is no ATX power supply adapter available for your PC.

Here are some UK-based purchase options for the 400-watt and 550-watt power supplies:

HP N03175-001 (400-watt) power supply purchase option: https://www.lambda-tek.com/HP-N03175-001-sh/B47115171?srsltid=AfmBOorWMyJitxl6I4l4DLSc5C3A3XZNfHw5w9....

HP M86264-001 (550-watt) power supply purchase option: https://www.ebay.co.uk/itm/405359783923?_skw=HP+M86264-001+SKO-PSU+550W&itmmeta=01JDE8CWXZ7ZGCM275ET....

Thanks, that is what I thought.
To make sure, this PSU is designed by HP and should be compatible, correct?

@DanRotman,

You are correct that the 400-watt power supply you referenced is made by HP, but that doesn't necessarily mean that it would actually work and/or is compatible with your PC.

You'll have to carefully check your 260-watt power supply's "P2" power connector, and see what the wire configuration is: I believe it will look like this:

And not like the 400-watt power supply you referenced:

Disclaimer: since HP does not provide a comprehensive power supply compatibility chart, sadly, you will have to experiment with power supplies like so many of us had to do.

The 400-watt power supply with p/n: L04618-800 may be your best bet if you don't want to purchase the OEM 400/550-watt power supplies I recommended, as seen here: https://www.ebay.com/itm/285458372229?_skw=L04618-800&itmmeta=01JDEBZ95BPKNZF5FYG0TAEMY0&hash=item42..., or: https://www.ebay.com/itm/275424620657?_skw=L04618-800&itmmeta=01JDEBZ95C13GB0MT9GG60PE8E&hash=item40....

The challenge is that none of us know for sure if this is going to work.

The aforementioned L04618-800 400-watt power supply is my very best guesstimate...

You are right, the ribbon pin in my desktop has 7 pins while theirs has 3. I doubt it will work.
I kept searching and found this PSU. It says its 400W and has the 7 ribbon pins. Can you confirm the compatability?

@DanRotman,

The "P2" power connector looks OK, but I cannot confirm it because the part number (M76036-001) doesn't give me any information: "No additional information found in PartSurfer." in HP PartSurfer (see: https://partsurfer.hp.com/?searchtext=M76036-001).

That doesn't necessarily mean that this power supply is incompatible with your PC. The Seller claims, and I quote: "Topic: For HP 680 G9,800 G9, Power Supply".

All I could tell you is that this power supply may work, but I cannot 100% confirm it.

Thanks a lot, I'll continue and contact the seller.
