PSU4100-03 Power Supply for Avalon Q Miner | 1700W Original Canaan PSU

PSU4100-03 Power Supply | 1700W Original Canaan PSU for Avalon Q Miner Replacement

The PSU4100-03 is the original Canaan Creative power supply for the Avalon Q cryptocurrency miner. Rated at 1700W with a universal 110-240VAC input, it delivers a primary 21.5-26V rail at 1700W for the hashboards and a secondary 12V / 100W rail for the control board and fans. Direct drop-in replacement when the original PSU fails or degrades.

Built-in overvoltage, overcurrent, and short-circuit protection safeguards both the PSU and the miner during transient events. C20 receptacle on the AC-input side — pairs with any standard C19-to-C20 mining-rack power cord.

When to Replace the PSU4100-03

• Miner refuses to boot — no LED activity at power-on.
• Intermittent restarts under load — PSU dropping mid-mining session.
• Audible coil whine not present during normal operation — internal degradation.
• Burning smell — component failure, immediate replacement required before further damage.
• Upstream breaker trips — failed PSU drawing short-circuit current.

FAQ — PSU4100-03 Avalon Q Power Supply

Q: Can I run the PSU at 110V residential mains?
A: Yes — universal 110-240VAC input. But at 110V the input current draw roughly doubles vs 240V (~20A at full load), so verify your circuit and wiring can handle that current. North American 120V mining setups typically use 240V service for this reason.

Q: How do I verify the new PSU is working?
A: After installation, measure rails with a multimeter at the hashboard connectors: main rail should read 21.5-26V (depending on load), auxiliary rail should read 12V ±5%. Run the miner for 10-15 minutes and check for stable hashrate before returning to production.

Q: Will this PSU work on other Avalon models?
A: No — the PSU4100-03 is specifically rated for the Avalon Q's 1700W power envelope and 21.5-26V hashboard rail. Other Avalon models (A1066, A1166, A1246) use higher-power PSUs (PSU3400 series).
