Antminer S23 — Bitmain’s Most Efficient Miner, Real Prices, In Stock

The Antminer S23 is the first Bitmain generation to reach roughly 9.5 J/TH. That single number is why it exists: it produces a terahash for about a quarter of the electricity an S19 needs, and it is the only current machine that stays profitable on expensive grid power. It is also hydro-cooled and rack-native, which means it is a build, not a purchase. Prices below are live and final — four S23 variants from $13,489.88 to $34,800.88.

If you have landed here from a spec sheet, the thing worth understanding before you look at price is that the S23 is not a faster S21. It is a different deployment model. There is no air-cooled S23 you plug into a socket. Every variant assumes a water loop, three-phase power and a rack. Budget for the room before you budget for the machine.


antminer s23

The Antminer S23 is Bitmain’s 2025–2026 SHA-256 generation, delivering roughly 580 to 1,160 TH/s at about 9.5 J/TH — the most efficient Bitcoin mining hardware the company currently ships.

Put the generations side by side and the trajectory is the whole story. An S9 burns about 98 J/TH. An S19j Pro burns 29.5. An S21 burns 17.5. The S23 burns 9.5. Each generation roughly halves the electricity bill attached to the same amount of work, and the S23 is where that curve finally makes mining viable on ordinary commercial power rather than only on subsidised hydro.

Concretely: at $0.12/kWh, producing one terahash-hour costs about $0.00114 on an S23 and about $0.00354 on an S19j Pro. You are buying a three-fold reduction in your only recurring cost. Over a four-year hardware life that gap is usually larger than the purchase price difference.

Antminer S23 HYD580 TH/s$13,489.88~$23.26

Two honest observations about that table, because nobody else will point them out:

First, the Antminer S23 HYD at $13,489.88 is the cheapest entry to this generation and the best $/TH of the five at roughly $23 per terahash. If you want S23 efficiency and can only justify one machine, that is the one.

Second, the S23 is the most expensive hardware per terahash in our entire catalog — about $23–$30/TH against roughly $9.36/TH on an S21 Plus. That is not a mistake in the pricing. You are paying up front to cut your electricity bill by two thirds. Whether that trade pays depends entirely on your power rate, and it is the single calculation you should do before ordering.


bitmain antminer s23 hyd

The Bitmain Antminer S23 Hyd is the hydro-cooled 580 TH/s variant, drawing roughly 5,510 W at about 9.5 J/TH.

Hydro cooling is what makes the efficiency possible. Air-cooled machines throttle because you cannot move heat out of the chassis fast enough; water carries roughly four thousand times more heat per unit volume than air, so the chips run at their designed clock continuously instead of backing off.

What it actually requires, stated plainly so nothing arrives as a surprise:

  • A closed water loop with an external dry cooler sized to your total heat load.
  • Antifreeze — we stock AFC02-AZ at $880.88. Do not run plain water.
  • Three-phase power, typically 380–480 V, with the distribution to match.
  • Floor loading that takes the weight of a filled loop.
  • A rack — the ANTRACK V2-EC4-DTHP at $8,888.88 or a full ANTSPACE container.

The upside nobody mentions: a hydro machine is dramatically quieter than an air-cooled one. The 75 dB problem that rules out home air-cooled mining largely disappears, because the noise was always the fans.

antminer u3s23h 1160 th/s

The Antminer U3S23H is the rack-native 3U variant producing 1.16 PH/s — 1,160 TH/s — from a chassis measuring roughly 900 × 486 × 132 mm at about 11,020 W.

One 3U module does the work of approximately 86 Antminer S9s while drawing under a quarter of the power those machines would collectively need. That is the density argument, and at farm scale it is decisive: the same megawatt of interconnection produces several times more hashrate, and interconnection — not hardware — is the thing you actually wait years for.

The U3 designation means it is designed to slot into a standard rack rather than sit on a shelf. If you are building rather than buying, this is the unit the rest of the build is sized around.

antminer s23 vs s21

The S23 runs at roughly 9.5 J/TH against the S21’s 15–17.5 J/TH, but costs about three times more per terahash to buy. Which one wins depends on one input: your electricity rate.

Here is the arithmetic, using a 580 TH/s S23 HYD at $13,489.88 against three S21 Plus units at $2,199.88 each ($6,599.64 for 705 TH/s):

Your power rateWhich winsWhy
Under $0.06/kWhS21 PlusElectricity is cheap enough that the efficiency premium never pays back. Buy more cheap terahash.
$0.06 – $0.12/kWhClose — model itThe crossover sits in this band. Hardware cost, expected holding period and difficulty growth all swing it.
Above $0.12/kWhS23 HYDPower dominates. The S23 saves roughly two thirds of your only recurring cost, every hour, for years.

The second factor most buyers forget: difficulty only goes up. An inefficient machine’s margin is squeezed from both ends as difficulty rises and its output falls. The efficient machine survives further into that curve. If you plan to hold hardware for three or four years rather than flip it, that argues for the S23 even inside the middle band.

FAQ

How much does an Antminer S23 cost?
Between $13,489.88 and $34,800.88. The Antminer S23 HYD (580 TH/s) is $13,489.88, the Bitcoin Miner S23 Hyd is $17,400.88, the S23e U2H is $19,030.88, and the 1.16 PH/s U3S23H variants are $29,800.88 and $34,800.88.

What is the efficiency of the Antminer S23?
About 9.5 J/TH, the most efficient Bitcoin mining hardware Bitmain currently ships — roughly 1.8x better than the S21 at 17.5 J/TH and about 10x better than an S9 at 98 J/TH.

Is there an air-cooled Antminer S23?
No. Every S23 variant is hydro-cooled or rack-native and requires a closed water loop, an external dry cooler and three-phase power. If you need an air-cooled machine, the Antminer S21 Plus at $2,199.88 or S21 Pro at $3,744.88 are the current options.

What hashrate does the Antminer S23 produce?
580 TH/s for the S23 Hyd variants and 1,160 TH/s (1.16 PH/s) for the U3S23H rack modules.

Antminer S23 or S21 — which should I buy?
Below about $0.06/kWh, buy S21 Plus units; cheap power means cheap terahash wins. Above about $0.12/kWh, buy the S23; electricity dominates and its ~9.5 J/TH saves roughly two thirds of your recurring cost. Between those, model it with your own rate and holding period.

What infrastructure does an Antminer S23 need?
A closed water loop with an external dry cooler, antifreeze, three-phase 380–480 V supply, floor loading for a filled loop, and a compatible rack such as the ANTRACK V2-EC4-DTHP. It is an electrical and mechanical project, not a plug-in purchase.

Is the Antminer S23 quieter than an air-cooled miner?
Yes, substantially. The 75 dB noise of an air-cooled Antminer comes almost entirely from its fans, which hydro-cooled machines do not have.

What warranty comes with the Antminer S23?
365 days from ship date, with the manufacturer covering replacement freight. See warranty for full terms.
