The FSP700-80PSA(SK) is engineered for industrial computing rather than consumer PCs. This 700W switching power supply combines high power density, 80 Plus Bronze efficiency and a rich set of protection features in a compact PS2 ATX housing. As an industrial IPC PSU it is ideal for server and workstation power supply upgrades, communication equipment and industrial automation power system solutions where reliability and compliance matter as much as raw wattage.

Industrial 700W switching power supply for IPC, servers and automation
According to the TPS Elektronik online product listing, the FSP700-80PSA(SK) is delivered in a compact PS2 ATX size (140 mm × 150 mm × 86 mm) with an integrated 80 mm cooling fan, IEC C14 AC inlet and a total output power of 700 W. The supply weighs around 2.13 kg and comes with downloadable technical data sheets and RoHS, CE, UL, WEEE and UKCA documentation, underlining its role as a CE and FCC compliant power supply ready for international projects.
On the FSP Group industrial platform, the FSP700-80PSA(SK) is described as an industrial level of switching power supply designed for easy maintenance. Its high-load components and active PFC circuit make it perfectly suited to harsh industrial environments, while the complete input and output feature set makes it a strong choice for server and workstation power supply roles as well as communication and automation equipment.
Electrical performance and protection features
The FSP700-80PSA power supply operates from a full range 90-264Vac input at 47–63 Hz, delivering regulated multi-output ATX rails (+3.3 V, +5 V, four +12 V rails, −12 V and +5Vsb). Voltage regulation is typically ±5 % for the main outputs, with low ripple and noise output specified as low as 50 mVpp on the 3.3 V, 5 V and 5Vsb rails and 120 mVpp on the +12 V outputs, ensuring clean power for CPUs, memory and sensitive I/O cards.
The total combined 12 V current of up to 56 A supports multi-core processors, high-end graphics and multiple drives in modern systems. Hold-up time of at least 16 ms at full load prevents nuisance resets during short input brownouts, which is crucial in industrial automation power system and communication racks.
To safeguard equipment, the PSU integrates output over voltage protection on all primary rails and short circuit protection on all outputs. In the event of a fault condition, the supply performs a resettable power shut-down so that downstream electronics remain protected until the fault is cleared. This behavior, combined with internal monitoring of temperature and current, underpins the product’s MTBF 100K hours reliability.
Efficiency, thermal design and fan cooling
The FSP700-80PSA(SK) is rated for 80 Plus Bronze efficiency, achieving around 85 % efficiency at 230 VAC input and typical load. High efficiency reduces waste heat, lowers cooling requirements and contributes to lower total cost of ownership — especially important when the PSU is running 24/7 in a server or industrial IPC chassis.
For thermal management, the design uses internal 4 cm fan cooling as part of the IPC PSU family concept and, in this model, an internal 80 mm axial fan located at the rear panel. Combined with optimized airflow vents on the housing, this ensures reliable cooling even under full 700 W loading and during burn-in tests at 50 °C ambient.
Environmental robustness and reliability
The datasheet specifies a wide operating temperature range from 0 °C to 50 °C at full load, with storage from −20 °C to +80 °C. This makes the unit appropriate for control cabinets, factory floors and telecom rooms where ambient conditions can fluctuate over time. The predicted MTBF 100K hours reliability (MIL-HDBK-217 at 25 °C, nominal input and maximum load) underlines its suitability for long-life deployments.
From a regulatory standpoint the FSP700-80PSA(SK) complies with key international safety and EMC requirements and is marketed as a CE and FCC compliant power supply. This helps OEMs and system integrators reduce the time and cost required to obtain approvals for finished server, workstation and industrial automation power system installations.

Typical use cases for the FSP700-80PSA(SK)
- Server and workstation power supply – powering multi-core CPUs, high-end graphics cards and large RAID arrays in 2D/3D design, simulation and data-logging systems.
- Industrial IPC PSU – supplying embedded controllers, vision PCs and edge compute nodes used in production lines and robotic cells.
- Industrial automation power system – feeding PLC racks, motion controllers and communication gateways in SCADA and process control architectures.
- Communication and networking equipment requiring stable multi-output ATX power with low ripple and noise output and robust protection features.
Conclusion
The FSP700-80PSA power supply delivers much more than 700 W of raw power. As a purpose-built industrial IPC PSU with active PFC circuit, full range 90-264Vac input, 80 Plus Bronze efficiency, comprehensive protections and internal 4 cm fan cooling, it offers a dependable backbone for server and workstation power supply needs, industrial PCs and communication systems. Its MTBF 100K hours reliability, wide operating temperature range and position as a CE and FCC compliant power supply make it an excellent long-term choice for engineers designing robust industrial automation power system platforms.
