Powering the Future
The HX1000W joins the family of well received HX Series Enthusiast 
Grade Power Supplies known for their rock solid stability, enhanced 
modular cable design and high efficiency. The Corsair HX1000W Power 
Supply sets a new standard by which all other high wattage power 
supplies will be judged. 
The Corsair HX1000W features six PCI-Express connectors, both 6-pin 
and 8-pin compatible, to power multiple high-end graphics cards and two 
EPS12V connectors for dual CPU configurations. The truly independent 
dual transformer, dual rail design allows for optimum load balancing 
resulting in greater performance and stability. Industrial-grade 105°C 
primary, secondary and solid state capacitors provide up to four times the 
lifespan of traditional components. 
The HX1000W not only delivers 
one thousand watts of clean 
power for the highest 
performance enthusiast systems, 
it does so at greater than 80% 
efficiency thanks to the 
double-forward switching design 
and multiple rail DC-to-DC 
converter. Due to its best-in-class 
efficiency the HX1000W is able 
to run cool and quiet with only a 
single 140mm thermally 
controlled fan.
