Key Takeaways
- The FSP700-80PSA is a 700 W industrial switching power supply designed for IPCs, servers, workstations and industrial automation systems.
- Active power factor correction (PFC), a wide 90–264 VAC input range and 80 PLUS Bronze efficiency support stable AC/DC conversion in international deployments.
- Low ripple and noise levels are specified on all output rails, together with output over-voltage and short-circuit protection for connected electronics.
- An internal fan-based cooling concept and a defined operating temperature range support continuous operation in enclosed IPC chassis.
The FSP700-80PSA(SK) is developed for industrial computing rather than consumer PC applications. It combines 700 W output power, 80 PLUS Bronze efficiency and multiple protection functions in a compact PS2 ATX form factor. Typical applications include server and workstation power supply upgrades, communication equipment and industrial automation systems where reliability, documentation and long-term availability are relevant design factors.

Industrial 700W Switching Power Supply for IPC, Servers and Automation
According to the TPS Elektronik product listing, the FSP700-80PSA(SK) is housed in a PS2 ATX enclosure measuring 140 × 150 × 86 mm. It features an IEC C14 AC inlet, an integrated 80 mm fan and a total rated output power of 700 W. The unit weighs approximately 2.13 kg.
Technical documentation, including datasheets and conformity information (RoHS, CE, UL, WEEE and UKCA), is available to support system integration and project documentation for international use.
On the FSP Group industrial platform, the FSP700-80PSA(SK) is positioned as an industrial-grade switching power supply designed with serviceability and long-term operation in mind. The use of high-load components and active PFC supports continuous operation in IPC, server and automation environments.
Electrical Performance and Protection Features
The FSP700-80PSA(SK) operates from a full-range 90–264 VAC input at 47–63 Hz and provides standard ATX output rails (+3.3 V, +5 V, four +12 V rails, −12 V and +5 Vsb). Voltage regulation is specified at ±5 % for the main outputs.
Ripple and noise levels are specified up to 50 mVpp on the 3.3 V, 5 V and 5 Vsb rails, and up to 120 mVpp on the +12 V outputs. This supports stable power delivery for processors, memory modules and I/O devices.
A combined +12 V output current of up to 56 A supports multi-core processors, graphics accelerators and multiple storage devices. A minimum hold-up time of 16 ms at full load helps maintain operation during short input voltage interruptions, which can be relevant in industrial and communication installations.
Protection functions include output over-voltage protection on major rails and short-circuit protection on all outputs. In fault conditions, the power supply enters a resettable shutdown state until normal operating conditions are restored. These measures are intended to reduce the risk of damage to connected systems.
Efficiency, Thermal Design and Cooling Concept
The FSP700-80PSA(SK) meets the requirements of the 80 PLUS Bronze efficiency class, achieving typical efficiency levels of approximately 85 % at 230 VAC input under standard load conditions. Improved efficiency reduces power losses and thermal stress in continuous operation scenarios.
Thermal management is achieved through an internal fan-based cooling concept. In this model, an 80 mm axial fan is integrated at the rear of the enclosure and works together with ventilation openings in the housing to support heat dissipation during continuous operation at elevated ambient temperatures.
Environmental Robustness and Reliability
The specified operating temperature range is 0 °C to 50 °C at full load, with a storage temperature range of −20 °C to +80 °C. These limits make the power supply suitable for use in control cabinets, industrial PCs and equipment rooms with variable environmental conditions.
The predicted MTBF of 100,000 hours is based on MIL-HDBK-217 calculations at 25 °C, nominal input voltage and maximum load. This value provides a reference for reliability planning in long-term industrial installations.
From a regulatory perspective, the FSP700-80PSA(SK) is supplied with documentation indicating compliance with applicable CE and FCC requirements, which may support system-level conformity assessments for servers, IPCs and industrial automation equipment.

Typical Applications
- Server and workstation power supply for systems with multi-core CPUs, graphics cards and RAID storage
- Industrial IPC power supply for embedded controllers, vision systems and edge computing platforms
- Industrial automation power systems supplying PLCs, motion controllers and communication gateways
- Communication and networking equipment requiring stable ATX power with defined ripple and protection characteristics
Conclusion
The FSP700-80PSA is a 700 W industrial IPC power supply designed for continuous operation in server, workstation and automation environments. With active PFC, a wide input voltage range, 80 PLUS Bronze efficiency and defined protection functions, it addresses typical requirements of industrial power system designs.
Its specified MTBF, operating temperature range and availability of regulatory documentation make it suitable for long-term projects where reliability, traceability and international deployment are important design considerations.
