Seasonic SSR-750FA Power Supply Unit 750 W

The Seasonic SSR-750FA is a 750 W ATX power supply unit designed for desktop PCs. It is 80 PLUS® Gold certified and delivers high efficiency, a fully modular cable set, and active cooling to support stable operation. The SSR-750FA pairs with the Seasonic CONNECT backplane concept that simplifies cable management by converting and distributing voltages from the main PSU to peripheral outputs and mounting inside the case by magnets. The package and availability may vary by region; contact your local Seasonic representative for time-to-market information.

Advantages

The SSR-750FA provides 750 W of continuous power with 80 PLUS Gold efficiency (approximately 90 % at 50 % load), modular cabling for cleaner builds, and an active cooling solution tuned for quiet operation. When used with the Seasonic CONNECT backplane, it reduces visible cable clutter by allowing two main power cables between the PSU and the backplane, which then distributes +12 V, +5 V and +3.3 V outputs as required. The unit’s black finish fits standard PC aesthetics.

Suitable for

• High-performance desktop systems requiring up to 750 W
• PC builds where cable management and a clean interior are priorities
• Systems using modular PSUs and magnetic backplane solutions such as Seasonic CONNECT

How to use

Install the SSR-750FA into a compatible ATX case following standard PSU mounting procedures and connect the 20+4 pin ATX connector to the motherboard. Use the modular cables provided for CPU, PCIe and SATA connections. If using the Seasonic CONNECT backplane, route the dedicated cable set from the PSU to the CONNECT device and mount the backplane inside the case with the supplied magnetic mounts; the backplane will convert and distribute required voltages (+12 V derived to +5 V and +3.3 V) to peripherals.

Recommendations

For best results, pair the SSR-750FA with the Seasonic CONNECT kit when aiming for minimal cable clutter. Ensure your case supports the CONNECT mounting method and verify cable lengths before final assembly. Maintain good airflow and follow manufacturer's safety instructions when wiring and testing the system.
