Iceriver BP-H-3640W Replacement PSU – KS3 / KS3L / KS3M / KS5L Kaspa Miners
Get your Kaspa miner back online with a direct-fit BP-H-3640-11-R-BG (S1) power supply. The unit accepts 180–285 VAC at 50/60 Hz and delivers a 10.5–14 V / 3,400 W main rail for the hash boards plus a dedicated 12 V / 240 W rail for the control board and fans. It is the factory-specified PSU for the Iceriver KS3, KS3L, KS3M, and KS5L, so all connector pinouts, mounting holes, and cable lengths match without modification.
Diagnosing a Failed Iceriver PSU
Common failure symptoms include the miner not powering on at all, fans spinning briefly then stopping, or intermittent shutdowns under load. Before ordering a replacement, check the AC input fuse and the mains cable. If those are intact, measure the standby voltage at the 12 V rail — if it reads below 11.5 V or is absent, the PSU's primary side has likely failed. A replacement BP-H-3640W resolves all of these symptoms and restores the miner to full Kaspa hashing output.
Installation and First-Power Checklist
Disconnect mains power and wait 60 seconds for internal capacitors to discharge before removing the old PSU. Slide the replacement unit into the chassis, secure the mounting screws, and reconnect the hash board power cables and control board cable in the same order as the original. Before powering on, verify that all connectors are fully seated and no cables are pinched. On first boot, monitor the miner dashboard for stable voltage readings and confirm the hash rate ramps to the expected level within the first five minutes.
