I would like to upgrade the RTX 3090 GPU on my desktop.
Primarily working with AI models, so the 24 gig cache is essential.

Will an RTX 4080 or 4090 work in this particular chipset/ motherboard?

Can I put a second GPU in this desktop? If so, do I need to upgrade the power supply?

Does Acer offer an upgrade service in Canada?

Can a RTX 5070 ti , 5080 or even a 5090 GPU?

model: Orion Predator 7000 PO7-640 EB11


Cheers from Canada

    Hi DavinciResolveuser

    GPU upgrade compatibility — PO7‑640 EB11 Your Orion Predator 7000 uses a standard ATX‑style board with PCIe x16 slots, so current‑gen Nvidia RTX 40‑series cards like the RTX 4080 and 4090 are physically compatible and will run, provided you have enough PSU capacity (these GPUs are power‑hungry: ~320 W+ for 4080, ~450 W for 4090). Acer’s higher‑wattage PSU options in this chassis are 800 W and 1200 W — check your current rating before buying.

    The “RTX 5070 Ti / 5080 / 5090” models you mentioned don’t exist yet in retail. No specs, power requirements, or dimensions are known, so all we can say is they will almost certainly still use PCIe x16 — but board length, cooler size, and PSU needs are pure speculation until launch.

    On running 2 GPUs:

    • The PO7‑640 motherboard layout is for a single primary GPU; while a second PCIe slot may exist for add‑in cards, there’s no factory SLI/NVLink support on Ada Lovelace cards (RTX 40‑series). Dual cards would be for compute purposes only, and would require:
      • Physical clearance in the chassis for a second triple‑slot cooler.
      • Adequate PSU headroom for the combined draw.
      • Proper airflow to keep both GPUs within safe thermals.
    • This chassis isn’t marketed or thermally profiled for dual high‑end GPUs, so it’s not a plug‑and‑play scenario — you’d be in custom‑mod territory.

    Bottom line:

    • ✅ Safe bet now: RTX 4080 / 4090, if PSU is sufficient.
    • ❌ Not realistic: Dual top‑end GPUs in stock chassis without major mods.
    • 🔮 Unknown: RTX 50‑series until official launch info is out.

    Your Acer PO7-640 model desktop has a mobo with a 24 pin standard oem PSU plug, so you can upgrade the PSU to the modern wattage modular PSUs that are on the market today that have the 24 pin ATX_POWER plug, as long as these PSU sizes fit into the case and the GPUs also fit into the mainboards 2x PCIE16Х spaces, so make sure that all this can be done to the PO7-640s case and there is enough space, if you don't want to upgrade the oem case.

    If you want to use both PCIE16Х slots with 2x gpu's then of course you need to upgrade the PSUs so that both RTX GPUs will have enough power for the system and the additional GPU, as its listed below.

    These PSUs is what Acer fitted oem into the PO7-640 desktop which are both an 800W powered PSU.

    If you want to fit lets say 2x MSI GeForce RTX 5090 32G SUPRIM SOC @ USD $2879.99 into your PO7=640s desktops into its 2x PCIE16Х slots (if they will fit) then you will first need allot of money😁(like USD $5.8k plus) then you will need to fist calculate the min PSU wattage power that the system and the RTX5090 requires which is a min 1000W PSU + for the 2nd RTX5090 an addition of 575W power which is a min total of 1575W PSU power that your desktop will require.

    Just as a guide, I suggest that you consider using one of the most premium and most powerful PSUs like the Corsair AX1600i model which aint cheap, as its about USD $525.00, as this would be the most suitable PSU that the 2x RTX5090 cards that you want to upgrade to requires, so follow the guide for the exact RTX gpu's that you want to upgrade to below or follow the NVidia links to figure out other RTX power requirements. Good luck and hope this helps you out.

    1. RTX5090 = for the total system it requires 1000W min PSU (GPU only 575W)
    2. RTX4090 = for the total system it requires 850W min PSU (GPU only 450W)
    3. RTX4080 = with the total system it requires 750W min PSU (GPU only 320W)

    Great, thank you for the very detailed answer.

    But I do see RTX 5080 and RTX 5090 cards for sale. The 5090 is about $3800 CAD.

    Today I looked at a desktop with an RTX 5090 for only $5400, but this particular brand sold through Newegg have been criticized for having a cheap case.

    Thanks. It is very good to know that I can swap out the 3090 with a 4090.

    I do have one more question: can you offer me a reliable source to upgrade my RAM from 32-64 Gig.

    The best way to upgrade and/or rebuild a desktop is to build it yourself if you are computer savvy, as buying prebuild desktops you will always have a component(s) that will be cheap and nasty like you mentioned the case, so built it yourself or buy a prebuilt but change the appropriate cheap components.

    Yes I see that there are cheap newegg prebuilds like these below, but you have to wonder what components they use and if they will last past 12 months like the Acer prebuilds?

    With the ram for the PO7-640 spec i7-12700 cpu, the ram that Acer specifies is the DDR5 4400 MHz with 288-pin DIMM type ram modules, which is strange for this cpu, as the i7-12700 model has an Intel designed max speed of DDR5-4800MT/s CL40 type ram, so the PO7-640 must run at 4800MT/s speed ram with the XMP enabled in bios.

    But you need to update the last bios version of the PO7-640 version R01-B0 and then enable the BIOS > Advanced > Extreme Memory Profile ( X.M.P.) > Enabled (This item Enables or Disables Extreme Memory Profile (X.M.P.) as doing this, should enable the PO7-640 desktop to run the DDR5-4800MT/s CL40 sped ram at 4x 16GB to a max 64GB, as specified by Acer. For the ram types and manufacturers, I suggest that you look at either the Crucial Micron type ram or the Kingston type ram for best results at DDR5-4800MT/s CL40 type ram individual modules or 64GB kits. Good luck and hope this helps you out.
