Product information

Description

QOLTEC ATX 350W is a desktop power supply unit designed for standard ATX desktop PCs. It delivers a continuous total output of 350 W and connects to motherboards via a 20+4 pin ATX connector. The unit features non-modular fixed cabling, active cooling with a 12 cm fan with automatic speed control, and a compact ATX form factor with a grey finish. It supports AC mains input 230 V / 50 Hz and is intended for basic home or office computer builds that require reliable, low-noise power delivery.

Advantages

The QOLTEC ATX 350W offers a compact and straightforward design that fits standard ATX cases while occupying minimal space. Integrated active cooling with a 12 cm fan keeps internal temperatures under control and the automatic fan speed control reduces noise during light loads. Non-modular cabling simplifies installation and reduces cost, and the unit’s construction conforms to common ATX sizing for compatibility with many desktop enclosures.

Suitable for

  • Home desktop PCs for everyday tasks (web, email, office applications)
  • Office workstations with standard storage and integrated graphics
  • Small form-factor ATX cases where space is limited
  • Basic system builds and repairs requiring a reliable 350 W PSU

Key specifications

  • Total output power: 350 W
  • Input voltage and frequency: 230 V / 50 Hz
  • Motherboard connector: 20+4 pin ATX
  • Cabling: non-modular (fixed cables)
  • Cooling: 12 cm active fan with automatic speed control
  • Form factor and dimensions: compact ATX, 150 × 86 × 140 mm
  • Finish color: grey
  • Acoustic level: approximately 23 dB under typical conditions

How to use

Install the QOLTEC ATX 350W into a compatible ATX or compact ATX case following the case manufacturer’s mounting instructions. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach the remaining fixed cables to storage drives, optical drives or other components as required. Ensure the system is powered off and disconnected from mains before connecting cables. After installation, connect the power supply to a 230 V / 50 Hz mains outlet and switch on the system. Verify fan operation and monitor system stability during initial power-up.

Usage recommendations

Use the power supply in a well-ventilated case and avoid blocking the 12 cm fan intake or exhaust. For stable operation, pair this 350 W unit with systems that use integrated graphics or low-power discrete GPUs and typical consumer storage; avoid connecting high-power add-on cards or multiple high-draw peripherals that could exceed the unit’s capacity. Regularly check internal cabling for secure connections and keep the PSU and case dust-free to maintain cooling efficiency and low noise.
