It is the OEM PSU spec'd to feed the T21's BM1368-class hashboards across their working voltage window, with the C20 mains inlet and the P13-style DC output cabling Bitmain uses on the latest generation of S21\/T21-class miners. We ship it brand new from our Shenzhen warehouse for fleet refresh and field replacement of failed units.\u003c\/p\u003e\n\u003ch3\u003eWhen to Replace the APW11A1216-1a\u003c\/h3\u003e\n\u003cp\u003eTypical APW11 family failure modes: full-power shutdown after a few minutes (fan or thermal sensor fault), no DC output with a slow blue or red LED blink (PFC stage failed), audible buzz \/ coil whine that wasn't there before (capacitor degradation), or output voltage drifting under load (degraded primary switching MOSFET). The APW11A1216-1a is field-repairable but the cost of a 3-4 hour bench session usually exceeds the unit replacement cost — standard ops practice in a T21 fleet is to swap to a known-good unit and either bench-repair or scrap the failed PSU.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003ePower down the miner, isolate the rack from mains and wait 5 minutes for capacitor discharge. Unplug the C20 mains, then unplug the P13 DC output cables from the miner shell. Note the orientation. Remove the failed APW11 from its mount, slide in the new APW11A1216-1a, reconnect the P13 cables to the same hashboard positions, then reconnect the C20 mains cable. Power up; the miner should see the new PSU within a few seconds. Verify hashboard voltage and current on the kernel log are within Bitmain's spec window for a T21 under full load.\u003c\/p\u003e\n\u003ch4\u003eAPW11A1216-1a Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAPW11A1216-1a (Bitmain original)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDC Output Range\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e12V to 16V (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eMax Output\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e3610W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatible Miner\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAntminer T21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eMains Inlet\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eC20 (200-240VAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDC Output Connector\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eP13 4-pin (per Bitmain spec)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCooling\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eInternal axial fan, temperature-managed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBrand new, Bitmain factory PSU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated APW11 \/ T21 \/ S21 Power Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/bitmain-antminer-apw17-1215a-power-supply-s21-s19jxp\"\u003eBitmain APW17 1215A PSU – S21 \/ S19j XP\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-hydro-psu-cable-power-bitmain-apw11-power-supply\"\u003eAntminer Hydro PSU Cable – APW11 \/ S21 Hydro\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/g5s12010c-silicon-carbide-power-schottky-diode-bitmain-antminer-apw11-power-supply-repair\"\u003eG5S12010C SiC Schottky Diode – APW11 PSU Repair\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/premium-c20-p13-ac-power-cord-bitmain-antminer-s21-s19jxp\"\u003eC20 to P13 AC Power Cord – Antminer T21 \/ S21\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEquipping a new T21 site or restocking spares? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for pallet-quantity pricing.
