HCG-750
Making quad rail power and highly advanced power supply design available at a popular wattage, the
HCG-750 features special High Current connectors and heavy-duty cabling, earning it NVIDIA® SLI®-
Ready and AMD Crossfire certifications. At the same time the HCG-750 is also 80 PLUS® BRONZE
certified for efficiency, and features active PFC with a swift, quiet 135 mm double ball bearing fan so
you know you're getting not only High Current, but also high efficiency and excellent cooling. If loads of
power, High Current engineering and exceptional efficiency are what you're after, the HCG-750 is the
perfect PSU for you.
STANDARDS AND FEATURES
The connectors and power specifications of the HCG-750 PSU are all compatible with ATX12V v2.32
and EPS12V v2.92 specifications. The HCG-750 features Universal Input, which automatically senses
when you connect the power supply to any AC power source between 100 - 240V without setting a
voltage switch. This power supply also features Active Power Factor Correction (PFC), which improves
the power factor value of the power supply by altering the input current wave shape, helping to power
transmission across the grid.
SYSTEM PROTECTION
A variety of industrial-grade safety circuitry will help protect your computer: Over Current Protection
(OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP),
Over Power Protection (OPP), Surge & Inrush Protection (SIP) and Brown-Out Protection (BOP).
Sometimes the PSU will “latch” into a protected state. You will need to power off the PSU and clear the
fault before it will function again. There are no user-replaceable fuses in your HCG-750.

80 PLUS® CERTIFICATION
80 PLUS® certification is the most widely recognized
independent standard in power supply efficiency. An
80 PLUS® certified power supply uses less energy and
generates less heat to stay cooler, run quieter and last
longer. The HCG-750 has been 80 PLUS® BRONZE
certified to be at least 82% efficient at a wide range of
operating loads; this will lower your operating costs
and help protect the environment.

INSTALLATION
Install the PSU into either the top or bottom of your case with the four screws provided. Refer to your
case manual if you are unsure where the power supply should be installed.
Connect the 24-pin main power connector to your motherboard.
Connect the 8-pin or 4+4-pin connector for the CPU. If your motherboard has an 8-pin socket with a
cover on some of the openings, we recommend that you remove the cover and use the 8-pin
connector.
Note: Please also refer to your motherboards manual for any special instructions.

6
Connect the AC power cord to the power supply AC inlet. Be sure to use the heavy-duty cord supplied
with your PSU.
PCI-E graphics cards use different amounts of power. For some, a single 6-pin connector is sufficient,
making the hardwired connector the preferred choice. More powerful cards use multiple connectors,
including the advanced 8-pin PCI-E connector. The 8-pin PCI-E connector on the PSU can be used as
either a 6- or 8-pin connector.
Hard drives, optical drives (CD/DVD/BluRay™) and other accessories will use either the older 4-pin
Molex connector or the newer 15-pin SATA connector. 4-pin Molex connectors have two black, one
yellow and one red wire. The SATA connector has an additional orange power wire.
When you have all the connections secured, turn the switch on the PSU to the “|” position.
