Power for multi-GPU workstations

The Thermaltake Toughpower XT TPX-1275M is a 1275 W ATX power supply built for systems that draw sustained high current. Its modular cable design lets you connect only the leads a dense build requires. The unit meets ATX 12V 2.3 and SSI EPS 12V 2.92 specifications for modern platform compatibility.

80 PLUS Platinum efficiency

Certification confirms 89 to 94 percent efficiency across 20 to 100 percent load, reducing waste heat and operating cost. Active PFC and a full-bridge LLC resonant topology with DC-DC modules keep voltage regulation tight. Japanese capacitors rated at 105 °C support long-term electrical stability.

Continuous output at 50 °C

The supply is rated to deliver the full 1275 W continuously with an internal chassis temperature of 50 °C. Hold-up time is at least 16 ms at 70 percent load on 115 V input. Smart fan control adjusts speed to thermal load while the S.P.T. indicator reports standby, power-good and temperature status.
