Technology Features

High Quality Japanese Made Electrolytic & Solid Capacitors

Toughpower XT PLATINUM features 105℃/221℉ Japanese made electrolytic capacitors & solid state capacitors with low ESR, which greatly improves the durability and offers the highest stability and reliability.

Full Bridge & LLC Resonance and Interleaved PFC Circuit Design

Toughpower XT Platinum adopts full bridge & LLC resonance circuit  for extremely stable performance & reliability. Besides, built in the interleaved PFC circuit, Toughpower XT Platinum also provides extremely high PF value and high PSU efficiency.  

S.P.T. Indicator: Quick Status Monitor

Every time you open the side panel of your chassis, you can see the PSU status quickly and easily. The S.P.T. Indicator with 3-mode LED (standby / power good signal / temperature) offers real-time monitoring over the power supply which not only helps users to know the PSU working status, but also indicates abnormal situations to protect the system.

Hybrid SLI / CrossFire X & Intel C6 State mode support :

  For best compatibility For C6 state CPU & Hybrid GPU mode  

C6 State CPU Mode

CPU load range from Max. to only 1W.

Nvidia & ATI/AMD multi graphic cards configuration

Hybrid mode will cause graphic cards load range from Max. to only 1W. Toughpower XT GOLD & PLATINUM series are able to maintain an ultra tight DC regulation to support the C6 state CPU mode and the hybrid graphic card power saving mode by its ZERO LOAD (0W) Design.

Fan Speed & Noise Level

Smart Fan control circuitry design, which offers three distinct operation modes, fanless mode, silent mode, and cooling mode. The Toughpower XT 1275W automatically adjusts fan mode and speed according to the ambient temperature level. This new design not only optimizes heat dissipation, but also keeps the most silent operation for your system by reducing unnecessary fan rotation.

ECO Design

80 Plus PLATINUM Certified

Toughpower XT Platinum 1275W saves energy through its high energy efficiency up to 94% and is 80 PLUS Platinum certified

ErP Ready
Toughpower XT 1275W fulfils the EU guideline for ErP (Energy-Related Products) that are scheduled to apply starting in 2010.
