G1240 / G1240A 2200W Replacement PSU for Innosilicon T2T 30T Single Barrel
The G1240A power supply unit is the factory-grade replacement PSU for Innosilicon T2T 30T / 26T, T2TZ, T2TH, T2THM and T2TH single-barrel ASIC miners. Rated for 2200W continuous output with a maximum of 2300W, it delivers 12VDC at 60A across the operating range — the right output profile for the T2T / T2TH hashboard family.
Built-in output short-circuit, over-current and over-temperature protection (with self-recovery on the OTP path) safeguards the miner from electrical fault events. Greater than 93% full-load efficiency and under 210mV ripple noise keep operating cost low and the hashboard rail clean.

Where the G1240A fits in the T2T single-barrel chassis
The G1240A is the dedicated PSU for the Innosilicon single-barrel form factor: 300mm long, 135mm wide, 63mm thick. It bolts into the rear of the T2T 30T (or T2TZ / T2TH variants) and feeds the hashboard through the standard Innosilicon power connector pair. The 2200W rated output covers the nameplate load of the 30T variant; the 2300W maximum gives headroom for short transients.
Compatibility
Brand-new replacement PSU for the G1240 / G1240A position on Innosilicon T2T 30T/26T, T2TZ, T2TH, T2THM and T2TH single-barrel miners. Pair with a fresh AC power cord rated for at least 16A / 250V on the input side. For a higher-current Antminer-family PSU, see the APW17 in the broader catalog.
Common failure symptoms
- Miner does not power on — original PSU draws no current on the mains
- Audible bang / smell from the PSU enclosure after a surge event
- Output voltage drops out of regulation under sustained 30T load
- OCP or OTP latching within minutes of start-up
- Loud fan noise with elevated case temperature — degraded internal cooling
Frequently asked questions
Does the G1240A cover the T2TZ and T2TH?
Yes — the same G1240 / G1240A unit covers T2T 30T/26T, T2TZ, T2TH, T2THM and T2TH single-barrel miners.
Is the output 12V fixed?
The DC output is 12V nominal with a 10.5-14V operating range to match the miner's voltage-tuning behavior under load.
What input voltage does it need?
200-264VAC, 50-60Hz. Single-phase 220V is the standard input. The G1240A is not rated for 110V mains.
Do you ship the AC power cord with the PSU?
The unit ships without the input cord. Order the matching C13↔C20 or C14↔C19 cord separately from our cable line.
