Seasonic FOCUS GX-750 ATX 3.1 v5
A compact v5 supply with connector uncertainty kept visible
FOCUS GX-750 ATX 3.1 v5 is worth comparing when 750 W meets the build requirement and a short 140 mm PSU body helps the enclosure layout. Identify the v5 revision explicitly; older FOCUS GX models are not interchangeable evidence. Before selecting a graphics card with multiple conventional power inputs, verify the included harness arrangement rather than assuming every listed connector is an independent cable.
Consider it when
- A checked single-GPU build whose exact cable requirement is confirmed for the v5 package.
Look again when
- The purchase depends on an unverified simultaneous 8-pin connector count or native-cable wattage.
THE SPACE IT NEEDS
Leave room beyond the PSU body
- PSU body length
- 140mm
The body length excludes the working space needed for plugs and cable bends. Drive cages and the case layout can reduce that space.
Check power and cable requirements ↗Based on the manufacturer specification record, checked . Check the exact revision and installation instructions before buying.
The checks that can change your choice
One independent conventional run is established; the rest needs confirmation
The catalog confirms one single-connector PCIe cable and records another dual-connector cable whose PSU-side arrangement was not established. It therefore leaves total simultaneous 8-pin capacity unresolved. Confirm the actual package and native 16-pin rating with the exact v5 manual before finalizing the GPU.
Check the whole power path
Compare the CPU and exact graphics card requirements with the PSU capacity and included connector arrangement. Count independent cable runs where the GPU manual requires them. Use only cables approved for this exact power supply; similar-looking modular plugs do not establish compatible wiring.

Explicit v5 model, not 2019 FOCUS GX or 2024 v4. Manufacturer cable table lists 1 single-connector PCIe cables plus one cable with two PCIe connectors. The PSU-side connection and simultaneously available 8-pin capacity of that dual cable were not established, so automatic connector totals remain unknown. Native 16-pin wattage also requires confirmation.
