What's the deal with the PW-120 on Ebay?
I've seen the PW-120 powersupply on these threads and also on Ebay, and it looks identical to the PW-70 made by Ituner. However Itunder doesn't mention it on their site. So is this a remarked Power Supply or something else?

Yeah - was told the same thing in an email 3 weeks ago. Their own FAQ says to check back in September!

The supplied Casetronic 60W supply was woefully underpowered, and this PW-120 was the only one I could find to fit in the case. I should get mine in a few days, so I'll be able to test it and answer questions. I'm very interested in how they can double the power rating without adding a regulator and massive heatsink somewhere.

The story behind how an Itunes PW-70 becomes an Audioforge PW-120:
Pop the old reg off.
Government solder a new, (hopefully higher rated one) in.
Fashion and apply a sticker saying "PW-120" exactly over "Itunes PW-60"
Presto-chango - sell 'em on ebay.
Before anyone asks, I'm not flipping that regulator over to get the number, you can all guess. I bought this one to work.

Oh man, that soldering job is horrendous. Is that the only component that is replaced? I guess you can just look at which componets have big solder blobs and flux mess and assume they were replaced.
Its amazing he is doing that. Replacing components is not a good way to change the power ratings, you also have to look at the power handling capacity of the copper tracks on the PCB.
You would think he could at least remove the silk screen ITuner markings. Bad news all around.

So, has anybody contacted Andrei at Ituner and told him about this knock off? I would think he would be grateful to know about it.

The funny thing is the motherboards that people are hooking these to don't need 7 amps on the 12 volts. The +3.3 and +5 are the bottle necks, even on a Pentium 4 application. Plus, I wouldn't trust this thing with a pentium 4 VRM in a car.
You know the stereo recievers that have an outlet on the back of them that is switched with the main power switch? This is like somone saying the 300 watt stereo reciever is 2000 watts because the outlet is rated at 1700 watts and the stereo is rated at 300. FALSE ADVERTISING.
This thing doesn't do anything to the 12 volts, it just lets more of the input go to the output. It doesn't regulate it filter it or anything. Just turns it on or off.

I bet no one has done any thermal testing on this thing at 7 amp draw on the 12 volts. That Mosfet is suppose to be soldered down to a board for heat sinking. Looks like they are relying on it not generating any heat. It is a good thing most people who buy these only drive a 1000 dollar car..

Be careful about this ebay listing!
I just dealt with this guy and he was COMPLETELY rude and unprofessional to me.
I would be VERY wary about his product as well as his customer service...especially after seeing some of the pictures of his "work"...
There are other ITX power solutions out there with higher wattage...my advice is go with those instead and steer clear of this guy...
