Power supply unit CHIEFTEC GPA-700s 700 W 20+4 pin ATX PS/2 Silver 120 mm fan

CHIEFTEC iArena GPA-700s is a 700 W power supply unit designed for PCs and servers, with a 20+4 pin ATX motherboard connector. It operates on 200–240 V AC (47–63 Hz) and features active cooling via a 120 mm fan. The unit comes in a silver finish and carries CB, CE and EAC certifications. Cable lengths include approximately 50 cm for the motherboard connector and 500/650/800 mm for peripheral connectors; overall efficiency is rated at 80%.

Advantages

The GPA-700s provides a stable 700 W output compatible with European mains (200–240 V, 47–63 Hz) and uses a standard 20+4 pin ATX connector for broad motherboard compatibility. Built-in active cooling with a 120 mm fan helps maintain operating temperatures, while the silver housing and regulator certifications (CB, CE, EAC) indicate conformity with applicable safety and electromagnetic standards. Cable length options support flexible internal layout.

Suitable for

• Mid-range desktop PCs
• Small office servers and workstations
• System builders assembling custom builds for European markets
• Upgrading older systems that require a 20+4 pin ATX supply

How to use

Install the PSU into a compatible PC or server chassis using the standard mounting points. Connect the 20+4 pin ATX cable to the motherboard and attach peripheral connectors to drives and other components as required. Ensure the mains input matches 200–240 V before powering on. Provide adequate case airflow so the 120 mm fan can dissipate heat effectively. Follow the chassis and motherboard manuals for connector seating and cable routing to avoid strain.

Recommendations

Use the GPA-700s in systems whose combined component power draw stays well below 700 W to ensure longevity and stable operation; maintain dust-free airflow around the 120 mm fan and verify mains voltage compatibility (200–240 V) before installation.
