Product information

Description

The Chieftec GPF-400P TFX Power Supply Unit delivers 400 W of reliable and stable power for compact computer systems and servers. Featuring a space-saving TFX form factor, this grey power supply unit is engineered to fit into smaller chassis without compromising on performance. It incorporates active cooling with an 8 cm fan to maintain optimal operating temperatures during daily computing tasks. With support for a wide AC input voltage range and multiple safety compliance certificates such as CE, EAC, and RoHS, it ensures safe and efficient operation for modern PC configurations.

Advantages

This power supply unit offers high reliability and efficient power delivery thanks to its active PFC and adherence to the ATX 2.3 specification.

Additionally, its wide input voltage range allows for stable performance under fluctuating electrical conditions.

  • Compact desktop computers and small form factor PCs
  • Entry-level and mid-range office or home servers
  • Systems requiring a TFX power supply unit replacement or upgrade

When it may not be suitable

How to use
