The FSP350-51TAC is a 350 W AC/DC power supply built in the slim TFX form factor for space-limited computer cases and industrial PC applications. Designed for 230 V AC mains with an input range of 180–264 V, it delivers full continuous power with 80 PLUS 230V Bronze efficiency to reduce wasted energy and heat. It follows the Intel TFX12V v2.52 design guide for fit and compatibility in standard TFX PSU bays. A single +12 V rail combined with DC-to-DC conversion helps provide stable outputs under varying loads. The unit also features active PFC with a power factor of up to 0.99 for improved input power utilization. Its smart fan speed control supports quiet operation during normal use. With compliance for CB 62368, CE, EMC, TUV, and KC, it is suitable for commercial and industrial integration.
The FSP350-51TAC is engineered for compact systems that need dependable power in a slim TFX footprint. Its 350 W output, single +12 V rail, and DC-to-DC architecture make it a practical choice for small form factor PCs, industrial controllers, kiosks, POS systems, and embedded platforms.
Built for 180–264 V AC operation, this model is especially suited to 230 V regions and environments where efficiency, compliance, and quiet cooling matter.

FAQs
for FSP350-51TAC 350W TFX Industrial AC/DC Switching Power Supply
No. This power supply is designed for 180–264 V AC input only, covering standard 220–240 V regions. It is not intended for 110–120 V mains operation without a suitable step-up solution.
It indicates the PSU is designed to reach Bronze-level efficiency on 230 V AC input, helping reduce wasted energy and heat generation. In practical use, this supports lower power loss and cooler operation compared with less efficient units.
It uses the TFX form factor with dimensions of 175 × 85 × 65 mm. It is intended for TFX-compatible small form factor cases and will generally require an adapter bracket for installation in a full-size ATX chassis.
A single +12 V rail allows the available 12 V output to be delivered from one rail rather than split across multiple rails. This simplifies power distribution and can make integration easier for systems with higher 12 V demand.
The smart fan speed control adjusts cooling performance according to system load and temperature. At lighter loads, the fan can run more slowly, which helps keep overall system noise lower during everyday operation.
The unit is specified with CB (IEC 62368), CE, EMC, TUV, and KC compliance references. These certifications support safe integration and regulatory suitability for a range of commercial and industrial environments.
Intel TFX12V v2.52 is a design guideline for Thin Form Factor power supplies. Compliance means the unit follows expected TFX dimensions, mounting conventions, and electrical design expectations for compatible compact desktop systems.
Yes. Its compact design, stable power architecture, active PFC, and listed compliance credentials make it well suited for industrial PCs, kiosks, POS systems, and embedded applications that require reliable continuous operation in a small footprint.
