Precaution

Please do not plug out the AC power cord when the Power Supply is in use, since even if done in a flash-like manner would cause damage to the components. Please do not store or implement the switching power supply under high humidity or temperature conditions. When putting an ATX type switching power supply under testing condition (Plug in alone / not installed in a PC case), it must be connected to a “Load” (e.g., HDD), before the switching power supply can be turned on (the Fan starting to rotate) and DC power output will be in operation. If not authorized, do not unscrew, open or tamper with the power units’ case for any reason what-so-ever!

Trouble shooting

If the Power Supply does not function normally, please check following: Check if the AC inlet connector is firmly plugged into the power supply receptable. (Be sure not to connect the power source) Make sure that the power connectors connect firmly to appropriate positions. Set the “I/O” switch to “O” status after the above checking and connect the power supply and power source. Select the “I/O” switch to “I” status and turn on the computer. Check if it can function normally. If the power supply still does not function normally after the above checking, please send the power supply back to your retailer or distributor.
