Making q ad rail power and highly advanced power s pply design available at a pop lar wattage, the
HCG-750 feat res special High C rrent connectors and heavy-d ty cabling, earning it NVIDIA® SLI™-
Ready and ATI™ CrossFire™ certifications. At the same time the HCG-750 is also 80 PLUS® Bronze
certified for efficiency, and feat res active PFC with a swift, q iet 135 mm do ble ball bearing fan so yo
know yo ’re getting not only High C rrent, b t also high efficiency and excellent cooling. If loads of
power, High C rrent engineering and exceptional efficiency are what yo ’re after, the HCG-750 is the
perfect PSU for yo .
S TANDARDS AND F EATURES
The connectors and power specifications of the HCG-750 PSU are all compatible with ATX12V v2.3 and EPS12V
v2.91 specifications. The HCG-750 feat res Universal Inp t, which a tomatically senses when yo connect the
power s pply to any AC power so rce between 100~240V witho t setting a voltage switch. This power s pply also
feat res Active Power Factor Correction (Active PFC), which improves the power factor val e of the power s pply
by altering the inp t c rrent wave shape, helping to power transmission across the grid.
S YSTEM P ROTECTION
A variety of ind strial-grade safety circ itry will help protect yo r comp ter: OTP (Over Thermal Protection), OVP
(Over Voltage Protection), SCP (Short Circ it Protection), OPP (Over Power Protection), and OCP (Over C rrent
Protection). Sometimes the PSU will “latch” into a protected state. Yo will need to power off the PSU and clear
the fa lt before it will f nction again. There are no ser-replaceable f ses in yo r HCG-750.
80 PLUS® C ERTIFICATION
80 PLUS® certification is the most widely recognized
independent standard in power s pply efficiency. An
80 PLUS® certified power s pply ses less energy and
generates less heat to stay cooler, r n q ieter 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 yo r operating costs
and help protect the environment.

P OWER O UTPUT & C ONNECTORS
The HCG-750 power s pply distrib tes power on separate rails. Some rails req ire a minim m load in order to r n.
To see the o tp t capacity and reg lation for each different voltage, see Table 1. A list of all available power
connectors can be fo nd in Table 2.

I NSTALLATION :
1. Install the HCG-750 PSU into either the top or bottom of yo r case with the fo r screws provided. Refer to
yo r case man al if yo are ns re where the power s pply sho ld be installed.
2. Connect the 24(20 + 4)-pin main power connector to yo r motherboard. If yo r motherboard ses a 20-pin
connector, detach the 4-pin attachment on the 24-pin connector.
Note: The detachable 4-pin section cannot be sed in place of a 4-pin +12V connector.
3. Connect the 8(4 + 4)-pin connector for the CPU.
Note: Please also refer to yo r motherboard ser’s man al for any special instr ctions.
4. Connect the PCI-E connector(s) to yo r graphics card(s). PCI-E graphics cards se different amo nts of power.
For some, a single 6-pin connector is s fficient, while more powerf l cards se m ltiple connectors, incl ding
the advanced 8-pin PCI-E connector. The 8-pin PCI-E connectors on the HCG-750 can be sed as either 6- or 8-
pin connectors.
5. Connect all Molex/SATA connector(s) to yo r hard drives, optical drives (CD/DVD/Bl Ray™) and other
accessories. Please note that some devices will se either the older 4-pin Molex connectors, while others will
se the newer 15-pin SATA connector. 4-pin Molex connectors have two black wires, a yellow, and a red. The
SATA connector has an additional orange power wire.
6. Connect yo r floppy drive if present sing the s pplied FDD connector shown in Table 2.
7. When yo have all the connections sec red, connect the AC power cord to the power s pply AC inlet, making
s re the se the heavy-d ty cord s pplied with yo r HCG-750.
