The two ATX12V CPU 2+2 (4-Pin) power cables can be combined to form an EPS12V CPU 8-Pin power cable. |
|
Sleeved Cables
All power cables are sleeved for easy cable management and improved air circulation inside the computer case. | |
| |
 |
| Multiple Safety Features
Safety features including Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection safeguard the system. |
|

Plugging the main power connector P1 into the motherboard while the product is connected to the AC power source may result in damage to the motherboard. |
|
|
Make sure that the connectors are connected to their designated locations, and that the connectors are not oriented in the wrong direction when connecting the DC output connectors. |
|
 |
If the Power On light fails to light up when the main power button is pressed after completing the installation procedure, then some devices may be plugged in incorrectly or the motherboard may be faulty. | |
