BitsPower 24‑Pin ATX bridge/tester con connessione ventola — BPTA‑PSC‑SOC

BitsPower 24‑Pin ATX Bridge/Tester with Fan Header (BPTA‑PSC‑SOC) is a compact adapter that connects to a standard 24‑pin ATX power cable to provide a reliable temporary power bridge and an integrated fan power output. The unit is intended for situations where a motherboard is absent or being tested: it allows ATX power supplies to be started and supplies a +12V fan header to run case fans or small 12V peripherals. The design simplifies bench testing of PSUs and short-term setups requiring a stable fan feed from the ATX connector.

Advantages

This adapter enables safe and quick activation of an ATX power supply without a motherboard, reducing the need for improvised wiring. The built‑in fan header delivers a direct +12V output for powering one standard case fan or other small 12V devices. Its compact form factor and standard 24‑pin connector make it compatible with a wide range of PSUs and convenient to carry for diagnostics or testing. The product is plug‑and‑play and minimizes handling of individual wires during setup.

Suitable for

• Bench testing and diagnostics of ATX power supplies
• Running a case fan or small 12V device without a motherboard
• Temporary test rigs, open‑bench systems, and repair work
• System troubleshooting where a dedicated fan power feed is needed

Key specifications

• Interface: Standard 24‑pin ATX female connector
• Fan output: Single 3‑pin or 4‑pin +12V fan header (provides +12V and ground)
• Primary function: ATX power bridging and fan power provision
• Form factor: Compact inline adapter for cable connection
• Compatibility: Designed for conventional ATX power supplies and standard case fans

How to use

Connect the adapter to the 24‑pin ATX cable from the power supply, ensuring the connector is fully seated. Attach a compatible case fan or 12V peripheral to the fan header. Once connected, power on the ATX supply using its switch; the adapter completes the necessary circuit to allow the PSU to start and delivers +12V to the fan header. Use this setup only for testing, temporary power, or diagnostics and avoid prolonged operation in uncontrolled environments.

Recommendations

Use the adapter on a non‑conductive surface and avoid connecting high‑current devices to the fan header. Verify fan polarity before powering on and monitor temperatures and fan operation during tests. Disconnect the adapter when not actively testing and follow standard safety practices for working with ATX power supplies.
