ASIC Power & Electrical Requirements
Before you buy an Antminer, check the electrical: most modern ASICs require a dedicated 240V circuit and will not run on a standard 120V outlet. This reference gives the stock wall power, required voltage, recommended breaker, matching Bitmain PSU and typical plug for every in-stock model.
Quick answer
Every ASIC miner has two electrical facts that decide whether you can even plug it in: how many watts it pulls at the wall, and what voltage it needs. Most modern Antminers are NOT 120V appliances — they require a dedicated 200-240V circuit, the same class of service as an electric dryer or EV charger, and will not start (or badly under-deliver) on a standard household outlet. This reference gives the stock wall power, the required voltage, a computed dedicated-circuit/breaker size, the matching Bitmain PSU and a typical plug for 11 in-stock models, so you can size your electrical BEFORE you buy.
The single most important buyer fact: of these 11 models, only the Antminer S9 and Antminer L3+ run on a standard 120V/15A household outlet — every S19, S21, T19 and L7 REQUIRES a dedicated 200-240V circuit (plan the electrical first; an S21 on 120V simply will not run). Figures are stock nameplate (Bitmain ~+/-5%, and firmware/tuning move them); breaker math assumes 240V single-phase, so 208V commercial service draws ~15% more current.

| Model | Hashrate | Stock power | Heat output | 120V? | Recommended circuit | Matching PSU |
|---|---|---|---|---|---|---|
| Antminer S9 SHA-256 Bible TDP = 1400W; Bitmain rated wall power for the 13.5T variant is ~1323W, so 1400W is conservative. Breaker: 1400W/120V=11.7A -> /0.8=14.6A -> 15A; at 240V only 5.8A. S9 stock variants vary (13.5T/14T, S9j 14.5T); D-Central S9s are typically refurb/as-is — verify per unit. | 13.5 TH/s | 1,400 W | 4,777 BTU/h 120V plug-and-play (heater-class) | Yes — 120V OK Runs on 120V. This is the ONLY model here that flexibly accepts 120-240V at full output, because the APW3++ PSU has universal 100-264V input. Ideal home/space-heater unit. | 120V / 15A (dedicated) OR 240V / 15A C13/C14 IEC inlet on APW3++ PSU; standard NEMA 5-15 cord at 120V (NEMA 6-15 if run at 240V) | APW3++ 1600W (or APW7 1800W) — both 100-264V universal |
| Antminer T19 SHA-256 84TH/3150W is Bitmain spec — Bible confirms model+chip (BM1398) but carries no T19 nameplate wattage. Breaker: 3150W/240V=13.1A -> /0.8=16.4A -> 20A. ~37.5 J/TH (lowest-efficiency S19-gen unit). | 84 TH/s | 3,150 W | 10,748 BTU/h 240V dedicated circuit | No — needs 240V REQUIRES 200-240V. Stock APW12 PSU will not start / under-delivers on 120V. Not a 120V unit. | 240V / 20A (dedicated) C19/C20 IEC inlet on APW12 PSU; 240V wall plug per install (commonly NEMA 6-20 for a dedicated 240V/20A circuit) | APW12 (12-15V, 3600W @220V) |
| Antminer S19 SHA-256 Bible stock = ~95 TH @ 3250W (34.2 J/TH); the 126TH-bin S19 tunes 67-130TH (1630-4700W). Breaker: 3250W/240V=13.5A -> /0.8=16.9A -> 20A. 120V derate path: APW3++ @1200W = 35-45 TH. | 95 TH/s | 3,250 W | 11,089 BTU/h 240V dedicated circuit | No — needs 240V REQUIRES 200-240V — Bible lists S19 as not 110V compatible (needs 240V). On 120V via APW3++ bypass it derates to ~1200W / 35-45 TH only. | 240V / 20A (dedicated) C19/C20 IEC inlet on APW12 PSU; 240V wall plug per install (commonly NEMA 6-20) | APW12 (12-15V, 3600W @220V) |
| Antminer S19 Pro SHA-256 Bible nameplate (BM1398 step-0): 675 MHz / 13.8V / 3245W / 110 TH/s ~= 29.5 J/TH. Breaker: 3245W/240V=13.5A -> /0.8=16.9A -> 20A. 114 chips/board (vs 76 on plain S19). | 110 TH/s | 3,245 W | 11,072 BTU/h 240V dedicated circuit | No — needs 240V REQUIRES 200-240V. Stock APW12 will not run at full power on 120V. | 240V / 20A (dedicated) C19/C20 IEC inlet on APW12 PSU; 240V wall plug per install (commonly NEMA 6-20) | APW12 (12-15V, 3600W @220V) |

Breaker: 3050W/240V=12.7A -> /0.8=15.9A -> 20A. | 100 TH/s | 3,050 W | 10,407 BTU/h 240V dedicated circuit | No — needs 240V REQUIRES 200-240V. On 120V via APW3++ bypass it derates to ~1200W / 40-50 TH only. | 240V / 20A (dedicated) C19/C20 IEC inlet on APW12 PSU; 240V wall plug per install (commonly NEMA 6-20) | APW12 (live probe: APW121215a, FW 0x71) |
| Antminer S19j Pro+ SHA-256 120TH/3355W is Bitmain nameplate (27.5 J/TH); Bible catalog gives a 21-profile band (65TH@1450W -> 159TH@5900W) with no explicit 'stock' row — nearest profiles bracket 116TH@3200W and 122TH@3500W. BM1362 5nm. Breaker: 3355W/240V=14.0A -> /0.8=17.5A -> 20A. | 120 TH/s | 3,355 W | 11,448 BTU/h 240V dedicated; garage / Hashcenter | No — needs 240V REQUIRES 200-240V.

| Antminer S19k Pro SHA-256 Bible explicitly: stock 120 TH @ ~2760W (23 J/TH). Breaker: 2760W/240V=11.5A -> /0.8=14.4A; a 15A breaker (12A continuous) technically holds but 20A recommended for headroom. BM1366 5nm. | 120 TH/s | 2,760 W | 9,418 BTU/h 240V dedicated circuit | No — needs 240V REQUIRES 200-240V. On 120V via APW3++ bypass it derates to ~1200W / 52-56 TH only. | 240V / 20A (dedicated); 15A minimum C19/C20 IEC inlet on APW12 PSU; 240V wall plug per install (commonly NEMA 6-20) | APW12 (12-15V, 3600W @220V) |
| Antminer S21 Pro SHA-256 234TH/3531W is Bitmain spec (~15.1 J/TH) — Bible confirms model+chip (BM1370) and APW17 PSU but no air-cooled S21 Pro nameplate wattage (only Hydro variants in the catalog). Breaker: 3531W/240V=14.7A -> /0.8=18.4A -> 20A; at 208V draw 17.0A -> 30A. | 234 TH/s | 3,531 W | 12,048 BTU/h 240V dedicated; garage / Hashcenter | No — needs 240V REQUIRES 220-240V (200-277V PSU range).

| Antminer S21 XP SHA-256 270TH/3645W is Bitmain spec (~13.5 J/TH) — Bible confirms model+chip (BM1370) + APW17 but no air-cooled XP nameplate wattage. Breaker: 3645W/240V=15.2A -> /0.8=19.0A -> 20A (only ~0.8A headroom under the 16A continuous limit — tight; recommend 30A for OC/208V).

| Antminer L3+ Scrypt Bible nameplate (Operator-confirmed): 504 MH/s @ 800W. BM1485 28nm, 144 chips. Breaker: 800W/120V=6.7A -> /0.8=8.3A -> 15A; at 240V only 3.3A. Older/as-is unit — efficiency (~1.6 J/MH) is poor vs L7; verify wall power per unit. | 504 MH/s | 800 W | 2,730 BTU/h 120V plug-and-play (heater-class) | Yes — 120V OK Runs on 120V fine — only 800W, well within a standard 120V/15A outlet.

Breaker: 3425W/240V=14.3A -> /0.8=17.8A -> 20A. | 9.5 GH/s | 3,425 W | 11,687 BTU/h 240V dedicated; garage / Hashcenter | No — needs 240V REQUIRES 200-240V. The L7 uses the 14-17V APW12 ('APW12+') variant and will not run on 120V. | 240V / 20A (dedicated) C19/C20 IEC inlet on PSU; 240V wall plug per install (commonly NEMA 6-20) | APW12 (14-17V / 'APW12+', 3600W @220V) — the higher-voltage L7/K7/DR7 variant, NOT the 12-15V S19 APW12 |
