Iceriver KS3 KS3L KS3M KS5L Control Board Power Cable for Stable Power Supply

Iceriver KS3 / KS3L / KS3M / KS5L Control Board Power Cable | Dual 6P Voltage Adjustment Cable for BP-H-3640 PSU to Control Board Connection

The Iceriver KS3 / KS3L / KS3M / KS5L Control Board Power Cable is the dual 6P voltage adjustment cable that connects the BP-H-3640 power supply unit to the control board on the Iceriver KS3 generation miners. Drop-in replacement when the original cable shows wear, scorch marks, or intermittent connection — restores reliable power delivery from the PSU to the control board and clears the boot failures, voltage drift, and random reboots that come from a degraded power cable.

Crafted from high-temperature resistant nylon with sustained-current copper conductors — handles the continuous load profile of an Iceriver KS3-class miner without thermal degradation. The dual 6P voltage adjustment design carries both the high-current rail and the regulation signals the control board needs to monitor the PSU. Direct OEM-equivalent replacement: same connectors, same pinout, same wire gauge.

When to Replace the Control Board Power Cable

• Visible damage on the original cable — scorch marks, melted insulation, frayed conductors at the connectors.
• Intermittent miner power-on — control board sometimes boots, sometimes doesn't, with no other obvious failure.
• Voltage drift readings in the miner dashboard — degraded cable resistance dropping voltage between PSU and control board.
• Random reboots under load — connector contact resistance rising under sustained current.
• Preventive PSU + control board service — refresh the connecting cable during a complete miner overhaul.

FAQ — Iceriver KS3 Control Board Power Cable

Q: Will this cable work for the KS5 (non-L) or KS5 Pro?
A: Designed for the KS3, KS3L, KS3M, and KS5L specifically — these share the same BP-H-3640 PSU + control board layout. The KS5 and KS5 Pro use different PSU families and need their own cables.

Q: How do I diagnose a degraded cable vs a PSU or control board fault?
A: Check both connector ends for discolouration or visible damage first. Then probe the cable resistance end-to-end with a multimeter — should read near-zero. Voltage-drop test under load is the definitive test: significant drop = cable is the problem, no drop = PSU or control board fault.

Q: Is it OK to splice / repair the original cable instead of replacing?
A: Not recommended for the high-current rail — splices add resistance and become a new failure point under sustained mining current. Full cable replacement is the reliable fix.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your monthly volume for tier pricing.
