Avalon 1346 / 1326 Conductive Copper Strip | Thickened Pure Copper Connector Kit for PSU3400 to Hashboard
This conductive copper strip kit is the PSU-to-hashboard connector for Avalon 1346 and 1326 miners. Carries the bulk DC current from the PSU3400 power supply output to the hashboard input bus. Built from thickened pure copper with a tin-plated surface for anti-oxidation and superior contact performance — critical at the current levels modern Avalon hashboards demand. Optimised for Avalon 1346 units with hash rates of 107T and above.
Ships as a complete kit: 2 pieces (positive and negative) for full PSU-to-hashboard connectivity. For Avalon 1346 models below 107T, a different strip variant applies — confirm with us before ordering if you're unsure which hash-rate tier your unit is.
When to Replace the Copper Strip
- Visible discoloration or burn marks at the strip contact points — oxidation or arcing damage.
- Hashboard intermittently dropping — degraded strip contact resistance under load.
- Excessive heat at the PSU output / hashboard input junction — corroded strip raising joint resistance.
- Bent or warped strip after a chassis-level service or rough handling.
- Fleet refit on aging 1346 / 1326 units — preventive replacement when refreshing PSU3400 stack.

FAQ — Avalon 1346 / 1326 Copper Strip
Q: My Avalon 1346 is below 107T — same strip?
A: No — the strip dimensions differ for the lower hash-rate 1346 variants. Confirm your unit's exact hash rate before ordering; we stock the alternative for sub-107T units separately.
Q: Why tin-plated and not bare copper?
A: Tin plating resists oxidation at the contact surface. Bare copper develops oxide layers that increase contact resistance over time, raising joint temperature and accelerating degradation. Tin-plated stays low-resistance for the life of the miner.
Q: Mounting torque on the retaining bolts?
A: Use the Avalon service-manual torque spec for the PSU3400 / hashboard interface bolts. Overtightening deforms the strip and reduces contact area; undertightening leaves a high-resistance joint that runs hot.
Q: Bulk pricing for Avalon fleet refits?
A: Yes — email contact@lys-sz.com for volume pricing on copper-strip kits.
