I've bought a Wells-Gardner 19K7201 monitor. My question is about power supply. I wonder if I could connect the monitor to an standard PC ATX power supply (for example: an Enermax model). If this could be possible, I could use a powerfull one to supply the whole arcade machine (monitor, PC, speakers and lights). Other question, what the hell is an issolation transformer ? This monitor says doesn't need one, but I'm not sure what this means.
Thanks for your answers. And sorry for my poor English skills.
I'm from Spain, so I use European 230v (if this matters)

No you can't.

An isolation transformer keeps the monitor from being damaged if something is wrong with the A/C power. It goes inbetween the household current and the monitor. Yours has the isolation transformer built in.

You're going to have to look up the manual for it, most newer monitors will take 230-240 Volts. If it does, all you need to do is hook it up to your power strip. If only takes 110-120 Volts, you'll need a step down transformer (travel shops should have them, for pluging US devices into European outlets), and plug it into that.

i'm curious as to why he couldn't, if his monitor has a builtin isolation transformer, why can't he just plug into the monitor power out at the back of the compouter's power supply?

Even if he didn't have the isolation transformer on the monitor, can't you just set it up like this:
PC power --> isolation transformer --> monitor ???
Or am I missing something on isolation transformers?

PC ATX power supplies output 3.3, 5, and 12V DC, not the 110-230 VAC a monitor would need. Old AT supplies used to have a switched AC output on the back, but I don't believe Enermax makes any ATX supplies with that.

that's odd, the three ATX's i just looked at in our den have switched 120AC monitor power at the back (the reverse standard computer power cord type, (not household plug) mind you, but still:-) as do both my old AT's p/s...now, they're not enermax, but i'd wager the majority of atx's have switched monitor output.. (on the outside of the case, not where you'd find your 5 and 12 volt dc's... ;D )
