Cooler Master Real Power 1250 Review

» Discuss this article (7)



Installation of a power supply is quite simple and only takes a couple of steps. First thing you will want to do, if you haven't already, is to remove the old power supply. To do this, first unplug it from the wall and remove all cabling from the motherboard and any components. Then remove the four screws in the back of the computer chassis going into the computer supply. Tilt the supply downward and out of the case. Since this is often so close to the CPU fan and other parts of the motherboard, I suggest you work slowly and cautiously, so that you do not cause any damage to parts already installed in your computer. If your case has a removable motherboard tray I suggest taking it out prior to changing the PSU.










Now that the old one is out, let's install the new one. Carefully slide the power supply into the PSU bay, watching that you don't damage any of the motherboard components or the CPU fan. Once into position, take the four screws included in the packaging and screw them in to secure the PSU. If you're into cable management like myself, now would be a good time to plan where you want your wires to go. Then plug in all of the cables needed and tuck away the ones not being used. This creates better airflow in the case.




Now that everything is installed and tucked away we need to connect the main power cable to the power supply. This power supply requires an outlet specified for 125V AC so make sure your house is wired for the right voltage before plugging it in and causing damage to something. Remove the warning sticker and plug in the cable. Once it has power, the LED above the plug will glow green letting you know there is power to the unit. This particular PSU does not have an on/off switch so to disconnect power you have to physically remove the plug from the unit.
