Upgrading my C24-1751. upgarding RAM, PSU and graphics card

Hi, I bought the above desktop after my last one from 10 years ago finally powered down. Managed to snag a display set at very low cost and decided I’d spend the savings upgrading it.

So far added RAM to 64Gb (manual says max is 32Gb but the system is reading and using all 64 just fine). Also added a 2Tb SSD. Now I’m thinking of tackling GPU and CPU but I need some advice first.

Right now the power supply is at 65W. I’m wondering if it’s possible to increase that given this uses an AC adapter and Acer doesn’t have a higher wattage charge using 3phy output.
I saw from the specs of the other models that the motherboard of the C-series can handle up to Core Ultra 7. Does anyone know if it can go beyond that?
I’m also thinking of adding a MXM or PCI graphics card but due to the power supply limitation, can only select a low power option like RTX A500 Mobile or 1030. The alternative is to buy a 4050 card and power it down which seems like a waste. Any recommendations for graphics card?
Also wondering if anyone has any experience swapping out the monitor for a better quality one? I found some displays that match the measurements etc but am not sure what will happen if I plug it in… last thing I want is the board to blow after I spent on all the upgrades.

Thanks

D

I believe the 1750 and 1751 use the same form factor motherboard. They likely also have the hooks for a SKU with a discrete GPU as shown, but I don't know of any versions of that one the market. If you look at this portion of the motherboard:

There is a place for a connector between those two screw holes at the right edge. That's what the GPU would plug into. So, to upgrade an existing system to use a discrete GPU you would have to find a SKU that has the GPU included, then go to the parts list for that SKU and order a replacement motherboard and GPU card. Not a simple process and likely more trouble than just buying an AIO that has a GPU already included. That's one of the main reasons I don't typically suggest an AIO to any of my friends, they are much harder to upgrade than a desktop since their designs look more like laptops.

The C24-1751 has a cpu integrated UHD Graphics and its cpu is soldered onto the mainboard and can't be changed. To change the cpu you need to buy a new mainboard with a more powerful cpu than the oem i3-1215U cpu like the i5-1240P or the i7-1260P which are available from Acer. The ram and M.2 SSD upgrades that you have done should speed your C24-1751 considerably as that is all the upgrades that you can do as a plug and play types upgrades.

With a dedicated gpu, you can go for an external eGPU setup, you can only connect the eGPU to the WLAN M.2 internal slot as the C24-1751 doesn't have a Thunderbolt port that these eGPU kits come with and connect with, as afterwards, you will not have a WLAN card as you will only be able to connect this AIO with its LAN Cat7/RJ45 port to the internet. Have a look at this excellent article "Connecting an external graphic card via PCI-E" as it explains it all for you. With the C24 screen, if you are going to go to all these upgrade extents you would be much better off buying a gaming desktop like the Acer Predator range like the PO3 or PO5 as these desktops are specifically built as gaming desktop and will be allot better no matter how much you upgrade the C24-1751 AIO. Good luck and hope this helps you out.

Hi Steven thanks for the suggestions. I did think of an eGPU but I was somehow under the impression that I could add a separate graphics card - I do see some of the configs for C24 with a separate GPU card and my mainboard has a space between the fan and board itself, that's joined by the heatsink. I mean, even an Arc A380M would be fine.

Just to clarify, my motherboard is the i5-1240P one. Not the i3.

As for the Predator, unfortunately they weren't on sale. I just want to see how far I can push this desktop to in terms of usability. I do some video and graphics work on it now, so a separate GPU would definitely help.

NO, with the C24-1751 AIO you can NOT add a gpu card, there is no room for it as its a slim AIO PC. There is no PCIe x16 slot for a gpu card on the mainboard as it would be impossible to add a gpu card and Acer does not have a slim gou card that can be added to this PC.

The 64GB 2x 32GB DDR4-3200MHz ram and the M.2 SSD PCIe4x4 drive which the quickest is either the 1TB or the 2TB Samsung 990 Pro, so hope you added that drive your C24, as with the 64GB ram those upgrades are the best upgrades to make your C24-1751 allot faster and better for gaming and editing and general use, but it will never make it into a gaming PC. Hope all this helps you out.

Note that the USB-C port is not a Thunderbolt, so many, if not all, eGPUs will not work. You can drive multiple monitors using a full feature dock, but the performance won't be too useful for gaming.

Thank you for your explanations, everyone.

So there is a version of the C24-1751 with a discrete GPU, there’s a manual and lifecycle extension guide for it.

In the image below, the mainboard is at the bottom, and the graphics card bridges the mainboard and fan.

My internal has an empty space where the graphics card is here. That’s why I was asking about the add-in.

The link to the guide is here:

But I’m super confused by how it connects to the mainboard and where I can get this component if at all.

Thank you. Thanks to your sharp eyes, I managed to narrow it down to a PCI-Express X1 Nvidia GeForce MX550 graphics card with max 35W TDP/TGP and will reach out to Acer to see what the cost is.

billsey

Very likely there is more involved than just soldering a connector in there. There are also probably support chips that aren't installed on the SKUs that don't have a GPU, hence the need for a MB replacement as well as the GPU card.
