Coolmax CUL-750B - User Manual

Model: CUL-750B
1. Function Description
This power supply is designed for personal computer. There are DC outputs:
+3.3V, +5V, +12V1, +12V2, +12V3, +12V4, -12V & +5V
SB
, and it provides
power to all computer systems and peripherals with maximum protection.
Here are some of the key features:
● Full Range Input Voltage (OPTIONAL)
● Active Power Factor Correction(OPTIONAL) ●
Surge Current Protection
● Input Transient Voltage Protection ●
Over Voltage Protection
● Over Load Protection
● Short Circuit Protection
● Low noise design ***
Compare with the conventional power supply which hires 80mm fan
assembled at the side of chassis, the power supply is assembled with a
120mm led fan horizontally located at the top chassis, with bigger fan blade, and
just right assembly location, it cools down the heating components
more effectively, and much low noise also gained.
2. How to Setup
It is rather simple to install this power supply to your precious computer tower.
Follow the steps below to finish the setup.
Step1: Open the computer tower cover; put the power supply into the
corresponding location of the tower, and then use right screws
to fix the power supply to tower.
Step2: Put the Main Power Connector, ATX12V Connector, Peripheral
Connectors, Floppy Connectors, PCI-Express Connector and many
others (when available) to the corresponding male sockets such as
main-board, peripheral devices (i.e. HDD, CDROM etc.) and floppy
drivers respectively. When you connect connectors, please pay
attention to the orientation of them because of the different hole sizes. Find
the proper orientation and push down firmly making sure that
the pins are aligned.
