G1286 / G1286A Power Supply Unit – Innosilicon T2T 37T Double Barrel
The G1286 / G1286A is the 2400W power supply designed for the Innosilicon T2T 37T double barrel miner. It delivers 12V output from a 200-240VAC, 47-63Hz input via the proprietary Innosilicon connector set used by the T2T chassis. This is the right replacement when the stock G1286 fails or weakens — third-party 2.4kW server PSUs typically can't sustain the transient current the T2T 37T demands at full hash without the controller logging a low-voltage event.
G1286 vs G1240 vs G1266
Innosilicon shipped multiple PSUs across the T2T family — the G1240 (single barrel 30T), G1266 (double barrel 30T) and G1286 (double barrel 37T). They share the same physical form factor and connector set but differ in power rating and output voltage range. Always match the PSU model to the miner exactly: a G1240 will run a 37T board but will trip on overcurrent under load, and a G1286 on a 30T board over-delivers without harm but is wasteful.
Installation
Mount the G1286 in the T2T chassis bay, route the DC harness to the hashboard power tabs (12V positive and ground), and connect the controller cable. AC input requires a 200-240V single-phase circuit (not 110V). Power on, wait for the controller to detect the PSU through its OK signal line, and verify the dashboard reports nominal voltage and full hash rate within 30 seconds. Operating temperature range -10°C to +50°C.
