Système de refroidissement informatique Alphacool 13335 plastique noir largeur 61 mm

The Alphacool Core ATX jumper plug (MPN 13335) is a compact plastic accessory designed to safely start a power supply unit (PSU) without powering the rest of the computer. With a slim black housing (61 mm width, 25 mm depth, 12 mm height), this jumper plug is intended for use when filling or testing water-cooling loops so that only the pump receives power while the motherboard and other components remain unpowered.

Advantages

The Alphacool 13335 jumper plug provides a straightforward and reliable way to activate a PSU independently of the mainboard. Its plastic construction is lightweight and electrically insulating, and the standard 24-pin form factor ensures compatibility with ATX power supplies. Using the jumper reduces the risk of accidental short circuits or component damage during loop filling and maintenance.

Suitable for

• Filling and testing custom water-cooling loops
• Powering pumps during maintenance without booting the PC
• Bench testing PSUs without connecting a motherboard

How to use

Unplug the 24-pin ATX cable from the motherboard and insert the Alphacool 24-pin jumper plug into the PSU's 24-pin socket. Connect the pump to the PSU or to a powered rail as required. Press the PSU or case power switch to start the power supply; the pump will receive power while the rest of the system remains off. Monitor the loop for leaks and proper flow while filling. After filling and verification, remove the jumper and reconnect the 24-pin cable to the motherboard before normal operation.

Recommendations

Use the jumper only with the case or PSU power switch and never attempt to modify the plug. Ensure tubing and fittings are secure and check for leaks while the pump runs. Always reconnect the motherboard 24-pin connector before powering the computer for regular use.
