Thread: HP tx2500z power supply

Power inverters, unless very pricey, tend to introduce unwanted noise and alternator whine into the audio system that is very hard, if not impossible, to isolate. I hard wired a DC/DC adapter into my car's wiring by cutting the lighter plug off and using those leads. I used a Kensington 120W unit that was easy to modify. I also tapped into the leads to the computer and checked the voltage and found a 5V lead that is perfect for powering my USB hub (not as easy).

Cheers
