If you picked up an ASUS Ascent GX10, a Dell Pro Max GB10, an HP ZGX Nano AI Station, an MSI EdgeXpert MS-C931, a Lenovo ThinkStation PGX, a Gigabyte AI TOP ATOM, or an Acer Veriton GN100 instead of an NVIDIA-branded DGX Spark, you're probably searching for the same answer: does the DGX Spark cable work with your box? Short answer: yes. All eight of these systems are built on the same NVIDIA GB10 Grace Blackwell Superchip reference design as the DGX Spark, with an identical ConnectX-7 200GbE port on the back (sometimes called the QSFP/CX7 port, sometimes just labeled "ConnectX-7" depending on the vendor). It's also commonly called the GB10 stack cable or the GB10 interconnect cable - different name, same part. The cable doesn't care which logo is on the chassis - it cares about the port, and that port is the same across all eight systems.
Short answer: yes
One cable covers all eight GB10 platforms — $79 or $174 at Resilient Tec
The NVIDIA GB10 reference design is shared across DGX Spark, ASUS Ascent GX10, Dell Pro Max GB10, HP ZGX Nano, MSI EdgeXpert, Lenovo ThinkStation PGX, Gigabyte AI TOP ATOM and Acer Veriton GN100 - same ConnectX-7 200GbE QSFP port, so the same cable links any pair.

Which GB10 Systems Does This Cover?
Eight vendors now ship a GB10-based desktop supercomputer. Each documents its own port slightly differently, but they all reduce to the same ConnectX-7 200GbE interconnect:
| System | Vendor | ConnectX-7 port | Direct 2-unit DAC |
|---|---|---|---|
| DGX Spark | NVIDIA | 2× 200Gbps QSFP | Yes |
| Ascent GX10 | ASUS | 2× 200Gbps QSFP | Yes |
| Pro Max GB10 | Dell | 2× 200Gbps QSFP | Yes |
| ZGX Nano AI Station | HP | 2× 200Gbps QSFP | Yes |
| EdgeXpert MS-C931 | MSI | 2× 200Gbps QSFP | Yes |
| ThinkStation PGX | Lenovo | 2× 200Gbps QSFP | Yes |
| AI TOP ATOM | Gigabyte | 2× 200Gbps QSFP | Yes |
| Veriton GN100 | Acer | 2× 200Gbps QSFP | Yes |
The Cable You Need
Part number: MCP1650-V00AE30. A 0.5-meter, 200G QSFP56 Passive Direct Attach Copper (DAC) Twinax cable, equivalent to the NVIDIA/Mellanox MCP1650-V00AE30. This is the exact same cable used to connect two DGX Spark units - because the underlying ConnectX-7 200GbE port is identical, it connects two ASUS Ascent GX10 units, two Dell Pro Max GB10 units, two HP ZGX Nano AI Station units, two MSI EdgeXpert units, two Lenovo ThinkStation PGX units, or two Gigabyte AI TOP ATOM or Acer Veriton GN100 units the same way. Resilient Tec sells the MCP1650-V00AE30 for $79.
If your units are not side by side, or you are cabling to a switch, the same Ethernet-coded cable comes in longer lengths: MCP1650-V001E30, 1 m ($97), MCP1650-V01AE30, 1.5 m ($104), MCP1650-V002E26, 2 m ($115) and MCP1650-V003E26, 3 m ($145).
"Note: While the port and cable are identical across brands, the physical location and labeling of the ConnectX-7 port on the rear panel can differ by chassis. Confirm the port location in your vendor's own manual before cabling, rather than assuming it matches the DGX Spark's layout exactly."
What Software Do You Need?
Once cabled, configure the ConnectX-7 ports as a direct Ethernet link, the same as on DGX Spark. NCCL handles GPU-accelerated collective operations and MPI handles inter-process CPU communication. Each vendor ships its own Linux-based OS image (DGX OS for NVIDIA, and each partner's own Ubuntu-based image for ASUS, Dell, HP, MSI, Lenovo, Gigabyte and Acer), so confirm your NCCL and driver versions match the minimums documented for GB10 systems.
Important Limitations to Know
- Direct DAC connections cover two units with one cable, or three units in a ring with three cables — each unit uses both of its QSFP ports, and no switch is needed.
- Four units: the supported route is an external switch, which is how most of these manufacturers document four-unit clustering. Four units can also run switchless as a ring of four cables using a custom NCCL build — it works, but it is not NVIDIA-supported.
- Confirm your vendor's exact port labeling, placement, and Ethernet/InfiniBand mode before cabling - see the note above.
Quick Checklist
- Two GB10-based systems: any combination of DGX Spark, ASUS Ascent GX10, Dell Pro Max GB10, HP ZGX Nano AI Station, MSI EdgeXpert MS-C931, Lenovo ThinkStation PGX, Gigabyte AI TOP ATOM, or Acer Veriton GN100
- One MCP1650-V00AE30 DAC cable (0.5m, 200G QSFP56, $79), or a 1–3 m MCP1650-V if the units are farther apart
- Confirmed ConnectX-7 port location per your vendor's manual
- NCCL and MPI installed and matched to your vendor's OS image
Where to Buy
Resilient Tec stocks the MCP1650-V00AE30 at $79 under a single listing that covers all eight platforms. Because the NVIDIA DGX Spark, Dell Pro Max GB10, ASUS Ascent GX10, HP ZGX Nano AI Station, MSI EdgeXpert MS-C931, Lenovo ThinkStation PGX, Gigabyte AI TOP ATOM, and Acer Veriton GN100 all share the identical GB10 Grace Blackwell reference design and the same ConnectX-7 200GbE port, the exact same cable works with every one of them - so there is no separate per-brand part to buy. Whichever system you own, this is the cable:
- NVIDIA DGX Spark, Dell Pro Max GB10, ASUS Ascent GX10, HP ZGX Nano AI Station, MSI EdgeXpert MS-C931, Lenovo ThinkStation PGX, Gigabyte AI TOP ATOM, or Acer Veriton GN100: MCP1650-V00AE30 — 200G QSFP56 passive DAC, 0.5 m — $79

FAQ
Does the DGX Spark cable work with the ASUS Ascent GX10, Dell Pro Max GB10 and HP ZGX Nano?
Yes. The ASUS Ascent GX10, Dell Pro Max GB10, HP ZGX Nano AI Station, MSI EdgeXpert MS-C931, Lenovo ThinkStation PGX, Gigabyte AI TOP ATOM and Acer Veriton GN100 share the NVIDIA GB10 reference design and the same ConnectX-7 200GbE QSFP port as the DGX Spark, so the same 0.5 m DAC links any two of them. Confirm the port location in your vendor’s manual before cabling.
Which cable connects two GB10 systems, and what does it cost?
The MCP1650-V00AE30 200G QSFP56 passive DAC, 0.5 m — $79 at Resilient Tec, with 1–3 m versions from $97 to $145. If you need NVIDIA’s named part, the NJAAKK-N911 QSFP112 stacking cable is $174. Both are sold new with a lifetime warranty (prices checked November 6, 2026).
Where can I buy the GB10 stack cable?
Directly from Resilient Tec, which ships from Knoxville, Tennessee, with POs and net terms available: MCP1650-V00AE30 — $79 at resilient-tec.com · NJAAKK-N911 — $174 at resilient-tec.com
Can I connect more than two GB10 systems with DAC cables?
Yes. Three units connect directly in a ring with three DAC cables, each unit using both of its QSFP ports, with no switch; three NJAAKK-N911 cables are $475 at Resilient Tec as a ring kit ($174 each separately), or three MCP1650-V00AE30 cables $237. Four units can also run as a switchless ring with four cables ($696 in NJAAKK-N911, $316 in MCP1650-V00AE30) using a custom NCCL build, which works but is not NVIDIA-supported. A switch remains the supported route at four units, and the only route past four — cable it with one MCP1650-V per unit at 1–3 m ($97–$145).
