Product information

Description

The Seasonic SSP-300SFB 300W power supply unit is a compact SFX-style PSU engineered for reliable desktop and small-form-factor PC installations. It delivers a rated total power of 300 W with a 20+4 pin ATX motherboard connector and non-modular cabling. Designed for universal compatibility, the unit supports an AC input range of 100–240 V at 47–63 Hz and includes active cooling. The stainless steel enclosure and multiple international safety certifications make it suitable for continuous operation in office, home, or light industrial environments.

Advantages

The SSP-300SFB combines a compact SFX form factor with a stable 300 W output and high efficiency. With an 80 PLUS Bronze certification and stated peak efficiency figures consistent with SFX design expectations, the unit reduces wasted energy and heat compared with lower-efficiency models. Its non-modular cabling ensures a simple, cost-effective installation, while the stainless steel housing improves mechanical durability and EMI shielding. Multiple safety approvals provide assurance for regulated deployments.

How to use

Install the Seasonic SSP-300SFB in a compatible SFX or adaptable small-form-factor chassis following the chassis manufacturer’s mounting instructions. Connect the 20+4 pin ATX cable to the motherboard and attach peripheral cables to components as required. Verify that the system’s combined component power draw stays within the 300 W rating. Ensure the unit receives proper ventilation and attach the AC input cable to a grounded mains outlet within the specified 100–240 V range.

Usage recommendations

For reliable operation, allow unobstructed airflow around the unit and avoid exceeding the rated load. Use the PSU in systems with compatible SFX mounting or with an appropriate adapter bracket.
