BP-F-500-05-R-BG Power Supply for Iceriver KS2 Lite & AL2 Lite

BP-F-500-05-R-BG Power Supply Unit | OEM Replacement for IceRiver KS2 Lite and AL2 Lite Miners

The BP-F-500-05-R-BG power supply is the OEM-spec PSU for the IceRiver KS2 Lite (Kaspa, kHeavyHash, 2 TH/s) and the IceRiver AL2 Lite (Alephium, Blake3, 2 TH/s) home miners. Both miners share the same 500W power envelope, which is why one PSU fits both models — released late 2024 as part of IceRiver's "Lite" home-mining series.

The PSU delivers 4.5-6.5VDC output at up to 100A on the main rail, accepting a universal 100-240VAC 50/60Hz input at 6.5A max. The wide AC input range makes the BP-F-500-05-R-BG compatible with virtually any global mining setup — North American 120V, European 230V, and Asian 220V infrastructure all work without modification. The S0.2 hardware revision is the current shipping variant.

When You Need a BP-F-500-05-R-BG PSU

• KS2 Lite / AL2 Lite won't start — original PSU dead, no startup tick from the transformer.
• Repeated overcurrent / overvoltage shutdowns in the miner controller logs.
• PSU draws AC input but produces no DC output — secondary-side bulk caps failed or main switching MOSFET shorted.
• Visible damage on the original PSU — burn marks, swollen capacitors, cracked PCB.
• Field-replacement for home-mining setups — bring a Lite miner back online same-day.

FAQ — BP-F-500-05-R-BG PSU

Q: Will this PSU work on the larger KS series (KS5, KS5L, KS7)?
A: No — the BP-F-500-05-R-BG is rated for 500W and matches only the Lite-series miners. Larger KS5 / KS5L / KS7 models pull 3000-3500W and require their own dedicated PSU (e.g. BP-H-3640 for the higher-power models).

Q: Same PSU for KS2 Lite AND AL2 Lite — is that really correct?
A: Yes — both miners use the same 500W chassis and the same low-voltage DC output spec (4.5-6.5V at 100A). The algorithm difference (kHeavyHash vs Blake3) is handled entirely on the hashboard ASIC side; the PSU sees the same electrical load.

Q: How do I confirm the PSU has failed vs the miner mainboard?
A: Disconnect the PSU output cables from the miner and measure the rails with a multimeter — some PSUs require a load to start. If both rails read close to spec, the failure is downstream. If outputs are missing or wrong, the PSU has failed.

Q: Can I run the PSU at 110VAC?
A: Yes — the universal 100-240VAC input means North American 110-120V residential service works without a transformer.

Q: Bulk pricing for repair shops or distributors?
A: Yes — email contact@lys-sz.com for volume pricing on IceRiver Lite-series PSU stock.
