I have a Clarion car audio system. I want to use it as an outdoor system on 120v. What kind of power supply does I need? Does something else should I take care of?


Car stereos require power for both red and yellow wires. You can twist them together, then black for ground. Not sure about your power supply setup. A standard ac to dc should work. Run speakers externally. Usually white and grey wires are front left and right and purple and green are the rear. good luck

Im putting power locks on my truck wanted to know where to connect the wires from the actuators to the alarm


Does the alarm support keyless entry if not you will need another alarm. If it does support look for any unused wires on the alarm module. Hook up a multimeter and look for 12vdc when pushing the unlock button on your remote

Most inverters create a modified sine wave output, which is similar to, but not the same as the AC you get out of the wall. The power supply for many laptops (and most transformers in general) will not run with a modified sine wave input. There are devices available that skip the inverter and the power supply. They go directly from 12VDC to what your laptop needs.

Will not boot to operating system or the bios. no messages and no beeps


You probably have a bad power supply or one of your components is bad. I don't have enough info to point to anything specific, but here is some ideas you can try.
1) unplug all components internally but the power supply and check for bios beeps. Not the front panel wires though.
2) swap power supply or check with voltmeter for +5vdc, +12vdc, and -12vdc.
3) check for operation of fans attached to motherboard.
4) most likely suspects are motherboard, processor, or power supply.

Want to use the atx-300-12z as a hobby power supply. Need 12vdc.


You're asking for a fire or just burning out the power supply. But,at your own peril, check the yellow wires for 12v or buy a power supply test adapter from ebay. It bypasses the power switch usually done by the motherboard & will fire up the power supply like it was connected to a board. Then test the wires for 12v. Should be any yellow wire,red is 5v. Green is 3.3 or 3v.
