## Summary description

FSP FSP400-70PFL is a 400 W internal computer power supply unit with a non-modular cabling design, an 80 mm cooling fan and grey housing. It provides stable DC rails for desktop PC builds, basic gaming or office systems, and component upgrades where moderate power is required. Suited for ATX-compatible cases and standard PSU installations.

## Long description

FSP FSP400-70PFL is a 400 W internal power supply unit designed for ATX-compatible desktop systems, industrial workstations and communication equipment that require a reliable, compact power source. The unit features a non-modular cabling design, an 80 mm cooling fan and a grey metal housing. Built with active PFC (power factor correction) and high-load electrical components, this PSU delivers regulated DC rails and complies with modern safety and EMC standards suitable for both office and industrial environments.
Advantages
The FSP400-70PFL offers stable 400 W output with active PFC to improve power efficiency and reduce line distortion. Integrated protection circuits include over current protection (OCP), over temperature protection (OTP), over voltage protection (OVP) and short-circuit protection across outputs, while resettable shut-down behavior aids recoverability after faults. The internal 80 mm fan with IEC 62368-compliant venting ensures consistent cooling, and the unit is manufactured with high-reliability testing including hi-pot and burn-in procedures to support continuous use in demanding ambient conditions.
Suitable for
Basic gaming and office desktop PCs with moderate power demands
Industrial workstations, servers and communication appliances
System upgrades where a dependable 400 W supply is required

How to use
Install the PSU into an ATX-compatible case following the case and motherboard manufacturer instructions. Secure the unit with the appropriate mounting screws, connect the main 24-pin motherboard connector, CPU power connector and any required peripheral connectors to drives and expansion cards. Ensure the PSU input is connected to a correctly rated AC source and that the case airflow is not obstructed to allow the internal 80 mm fan to provide adequate cooling. Verify BIOS and system settings after first power-up and monitor voltages under load to confirm stable operation.
Usage recommendations
For reliable long-term operation, use the FSP400-70PFL in systems with moderate power draw, maintain clean case airflow and ambient temperatures within the device testing range, and employ appropriate surge protection on the AC input. For industrial or server deployments, allow for adequate ventilation around the PSU and schedule periodic inspections to ensure connectors and cabling remain secure.
