Compact SFX power for small builds

The Seasonic FOCUS SGX-750 2021 is a 750 W SFX12V unit built for compact systems that still demand high output. Its 100 mm length and full-modular cable set let builders use only the connections they need, keeping tight interiors tidy and airflow clear.

750 W headroom with Gold efficiency

A single +12 V rail delivers 62 A, giving ample headroom for modern GPUs and CPUs while the 80 PLUS Gold rating keeps waste heat low under typical loads. The unit tops out at its rated 750 W, so sustained draws beyond that will trip protection circuits.

Hybrid fan control and broad protection

A 92 mm fluid-dynamic-bearing fan runs in three stages, starting with a fanless mode at low load before moving to silent and cooling modes as temperature rises. Full modular cables include two EPS, four PCIe 6+2-pin, six SATA and three peripheral connectors, while OPP, OVP, UVP, OCP, OTP and SCP safeguard the rest of the build.

商品問答

Will this SFX unit fit in a case that only accepts power supplies up to 100 mm long?

The housing is 125 mm long, so it exceeds a 100 mm limit and will not fit in that case.

Can the included cables reach the motherboard and graphics card in a mid-tower build?

The 24-pin cable is 350 mm, each CPU cable is 400 mm, and the PCIe cables are 500 mm, which is sufficient for most mid-tower layouts.

Does the fan stay off under light loads?

Yes, the hybrid control runs in Fanless Mode at low load, then moves to Silent Mode and Cooling Mode as temperature rises.
