Product information

Description

Evolveo EP350PP12B is a 350 W ATX power supply unit designed for basic office and home desktop systems. The unit provides 350 W of total output with approximately 80% efficiency and complies with Standard ATX 2.2. It includes a 20+4 pin ATX motherboard connector, passive PFC, four SATA connectors, a 120 mm cooling fan and a stainless steel housing. Cabling is non-modular with a motherboard cable length of 35 cm. CE certification and RoHS compliance are provided.

Advantages

The power supply combines a compact 350 W output with a 120 mm active fan for stable thermal management. A 20+4 pin connector ensures compatibility with ATX motherboards while the included SATA connectors allow direct connection of storage devices without additional adapters. The stainless steel casing offers mechanical durability and EMI shielding, and passive PFC helps maintain input power stability. Non-modular cabling keeps setup simple for basic builds.

Suitable for

  • Office desktop PCs for everyday tasks such as web browsing and document editing
  • Home systems with basic multimedia playback and light productivity workloads
  • Small form factor ATX-compatible builds that require a standard 20+4 pin connector
  • Upgrades or replacements for existing low-power desktop power supplies

Key specifications

  • Total power: 350 W
  • Efficiency: 80%
  • Motherboard power connector: 20+4 pin ATX
  • Standard: ATX 2.2
  • Power factor correction: Passive PFC
  • Fan diameter: 120 mm
  • Cabling: Non-modular; motherboard cable length 35 cm
  • Storage connectors: 4× SATA
  • Material/colour: Stainless steel / grey
  • Certifications: CE, RoHS compliant

How to use

Install the Evolveo EP350PP12B into a compatible ATX chassis, aligning the mounting holes and securing the unit with screws. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach the SATA connectors to storage drives as needed. Ensure the case fan orientation and cable routing do not obstruct airflow. Connect the mains cable to a properly grounded outlet and switch on the system. Verify stable boot and monitor fan operation and voltages in the BIOS or with system utilities during initial power-up.

Usage recommendations

Use this power supply in systems where total system power draw stays well below 350 W to maintain efficiency and longevity. Keep internal case airflow unobstructed around the 120 mm fan and perform periodic dust cleaning. For systems with high-power graphics cards or multiple power-hungry components, select a higher-capacity PSU with appropriate connectors.
