Now question that the HX1050 has abundant power for hardcore gaming. The Corsair HX1050 is also rated 80 plus silver. The efficiency means now longer is the gaming room hot as hell when playing an action shooter. The Corsair HX1050 utilizes advanced DC-to-DC circuitry and Corsair claim that it exceeds 80 PLUS Silver certification standards, with up to 88% energy efficiency (115v). There are plenty of flat, low profile modular cables supplied, with the ability to power 3 high end graphics cards, 6x 6+2 pin PCI E power connectors are supplied. There are also 2 x 8 pin EPS12V connectors for higher demand system builds.

Inside, the HX1050 has a Yate Loon D14BH-12 140mm fan. This fan has been used in many quality power supply designs in recent months and can generate up to 140cfm of air at 2,800 rpm while emitting 48.5 dBa. Obviously we would assume it won’t need to generate these speeds in operation, but the potential for some hardcore cooling is available.

CWT is the OEM for Corsair for this DC-DC Circuit design and the layout and build quality is exceptionally good. We would expect this from CWT however as all their designs to date have been engineered to the highest standards. There are several carefully placed heatsinks with thermal control sensors, ensuring the PWM fan generates the correct level of cooling.

The two primary capacitors are rated at 470uF/450V. Noise suppression is stellar with both +3.3V and +5V output peaking at 15mV, while the +12V output hits only 30mV under full load conditions, well within the ATX rated tolerance guidelines.

The carbon pile shows the HX1050 does put out the claimed power. Testing at max had the fan spinning like mad but this is typical. The 12V only sagged slightly as the load reached 1050W.
