WHAT IS THE CAPACITY OF SMPS


Hello Mkmanishbit2 hi, SMPS means switch mode power supply. The capacity of an SMPS unit is from 200 watts to 1500 watts, and some can be 2000 watts. Now for your Gigabyte Motherboard, a standard 350 watts unit will do, for medium end gaming, 500 watts will be enough, and for high end gaming, use the 800 to 1500 watts unit. Reminder the higher the watts number the higher the price, but the safer it becomes.

No power coming on intel desktop motherboard d845


Check the power supply to the motherboard i.e the SMPS, if it is working the fan of the SMPS will rotate. If the SMPS is ATX you can check it without connecting it to the motherboard. Unplug all the SMPS power connectors from the motherboard and then short circuit the green and the black wire of the 20pin connector of the smps, if the SMPS is working the fan of the SMPS will rotate. If the SMPS is in good condition and working, than it might be a problem in the internal circuit of the motherboard.

Power supply works but pc doesn't power up no lights and fans dont work


Have you checked the power supply in different system? If yes then first replace CMOS battery and switch the CMOS battery jumper. And while doing this please unplug the hard disk or optical drive data cables and power. If it does not work then check the power switch is working or not or it is perfectly connected with the front panel PINS on the motherboard. If it is not connected perfectly computer will not start after pressing power button.
Second Level Test : Remove the CPU Fan - replace the CPU perfectly - again place the Fan.

Third Level (motherboard test): Just take the motherboard removing CPU,RAM, SMPS - use another same type CPU, RAM and SMPS - if it does not work so it is motherboard problem. If it works may be CPU problem.

I have a D946GZIS motherboard. It does not boot whenever i switch it on and press the power button. Also the power led is not glowing. What must be the problem..? pls help ..


Starting at the begining. The wall socket, the plug, the cable, the power socket on the SMPS at the back of your PC, the SMPS, the Output connectors from the SMPS to the motherboard. The power LED not glowing means that the power is not reaching the motherboard. Disconnect and reconnect the power connector on the motherboard. start. No start. Does the fan on the SMPS work? If yes then all components before the SMPS are doing fine. If no then most likely connection socket power cable to the SMPS may be the culprit. This has a lot of load on it. The PC and the monitor both take power from this socket. the answer to your problem lies in the answer to my question whether the fan starts in the SMPS or not. If yes then there is no output from the SMPS and the SMPS need to be given the due attention and if no then there is no power input to the SMPS and various cables and socketc need that attention. In case you need to and can remove and open the SMPS look for bulged or burst capacitors. If found, replace them. Those round cylindrical components.
