Monitor/PSU Question (bartop build)

Pages: (1/3) > >>

EvilGreenDevil:

OK I have been holding off on posting this question for a while because I was determined to find the answer through some research on my own. After a lot of googling and thread skimming, I am still stuck.

It's my first build and its a bartop cabinet so space it tight. I basically bought a whole new computer system (nothing too fancy) for the build except for a monitor. I saved a 17" 4:3 lcd from my college days and I'm glad I did. Here's a link

I've read all over the place about wiring your monitor to the PSU so long as everything stays properly grounded and there's enough power output from the PSU. My question is that based on the specs of the monitor (listed in the link), would it even be possible to wire to a standard 450w PSU?

I know the PSUs that I have beeen looking at have 12V rails to work with. Call me crazy but 12V doesn't really translate to the 110v-220v that the monitor needs and that comes from the wall.

Sorry for the rookie question but I feel like I can't find the answer I'm looking for.



Bramlet:

You probably know this but both your computer power supply and the monitor take in 120 volts AC and convert to various voltages DC.

Nobody is powering their monitor off the 12v rails unless they are bypassing the monitors internal transformer since the 12v rail is already DC. Your monitor does run on DC but takes in AC and converts to DC. So you will need to be bypassing the monitors internal power supply cicuitry.

You could probably do it but you would need to be opening the monitor and finding an appropriate place to solder wires out of the power supply.

GregD:

 Is the power supply inside the monitor or does it have an external power brick?

BobA:

If it has a power brick you can determine the voltage and the amperage of the brick.  It says your monitor uses 34 watts so at 12 V that is close to 3 amps at 120V it is .3 amps.   If it is a 12V brick you can usually supply your monitor from it but if its not 12v you will have to use the brick to supply power.  The latest monitor I used had a 19V DC brick so I had to put the brick in the cab since 19V was not available.

The brick or monitor should also show what the polarity of your plug is.  This is essential to know if you are plugging into your computer's 12V rail.

If your unsure could just use a powerstrip and stick it somewhere.
