Yes. MINISFORUM specifies upgradeable RAM and storage for the AtomMan G1 Pro, and a hands-on review reports that its graphics card can be replaced. The limits are important: memory and SSD support have stated specifications, but MINISFORUM does not publish a validated list of replacement GPUs. A graphics-card swap therefore needs careful, model-specific fit and power checks.
What can be upgraded?
| Part | Manufacturer specification | What a review observed |
|---|---|---|
| Memory | Dual-channel DDR5-5200 SO-DIMM, up to 96GB | Tom’s Guide found a second memory slot on its review unit; that sample had one 32GB module installed. |
| Storage | Two M.2 2230/2280 PCIe 4.0 x4 NVMe slots, up to 4TB per slot | Tom’s Guide found a 1TB SSD installed and the second slot free on its review unit. |
| Graphics card | PCIe 4.0 x16 internal connection, 350W power supply; factory configuration lists an RTX 5060 | Tom’s Guide describes the factory low-profile card as replaceable, but no supported replacement-card list is published. |
Specifications are from MINISFORUM’s AtomMan G1 Pro product page. Review-unit observations are from Tom’s Guide’s 2026 review; configurations may differ between retail units. The two stated SSD capacities add up to 8TB when both slots are populated at their specified maximum.

Upgrading RAM
The stated memory format is DDR5-5200 SO-DIMM, with dual-channel support and a maximum capacity of 96GB. The review’s one-module, 32GB arrangement is specific to its sample, not a promise about the configuration in every box. Check the modules already installed in your unit before buying: adding a matching module may be possible, while reaching a different capacity may require replacing one or both modules.

- Match the SO-DIMM form factor and DDR5-5200 specification.
- Check module count, capacity, and current arrangement before deciding whether to add or replace memory.
- Do not treat a particular third-party kit as certified: the consulted sources do not validate specific kits.
Adding or replacing an SSD
MINISFORUM lists two M.2 2230/2280 PCIe 4.0 x4 NVMe slots, each specified for drives up to 4TB. Choose an NVMe drive in a supported physical length; the specification does not establish compatibility with SATA M.2 drives. Although Tom’s Guide found the second slot empty beside a 1TB drive, inspect your own unit rather than assuming it is unoccupied. The reviewer also noted an additional SSD heatsink in the review box; that is not established as a universal bundle inclusion.

- 【Expandable Storage】This Mini Computer has pre-installed 32GB DDR5-5200MT/s RAM and 1TB M.2 2280 PCIe4.0 SSD. However, you could expand the DDR5 RAM up to 64GB and 2TB for the SSD. There is another M.2 2280 PCIe4.0 slot available for expanding the storage. Without worrying about lack of capacity, you can run software smoothly, watch and storage large-scale movies, photos without any stress.
- Confirm the drive is NVMe, not merely an M.2-shaped SATA drive.
- Check whether it is 2230 or 2280 length and whether that slot is available in your unit.
- Keep the stated limit in view: up to 4TB per slot.
Replacing the GPU: possible, but not a guaranteed drop-in upgrade
The product specification identifies a PCIe 4.0 x16 internal connection and a 350W power supply. Tom’s Guide reports that the installed low-profile graphics card can be swapped. Together, these establish a physical upgrade possibility—not that any particular replacement card is supported. The manufacturer page does not provide a compatibility list, and the available sources do not confirm a specific next-generation replacement.
Before buying a card, verify the exact model’s height, length, thickness, power draw, required power connectors, cooling needs, and display outputs. Confirm fit and support for the particular AtomMan G1 Pro configuration with MINISFORUM or the seller. A card that uses the same PCIe connection may still exceed the system’s physical, electrical, or thermal limits.

What to check before ordering
- For RAM: inspect the installed modules, then match DDR5-5200 SO-DIMM format and plan capacity up to the stated 96GB maximum.
- For storage: check which slot is free, verify the drive is NVMe, and match a supported 2230 or 2280 length; the stated maximum is 4TB per slot.
- For a GPU: identify the exact replacement card and verify dimensions, power, connectors, cooling, and support for your precise system configuration. Do not infer compatibility from the PCIe x16 connection alone.
