HolyCRAP! Check out the real photos of the new smaller PS2

it has one thing for drawing power unlike the PSO it takes a compleate 8.5V and that gets split in to 3.5v for the DVD and 5 for the board.

So the PStwo only needs at most 5v and the fan only requires the 8.5v? T'm just making sure I'm hearing right (or reading).

I don't see how not having the fan would cease the ps2 from working, so I'm saying 8.5V for the ps2.

but if the 8.5v is used for the fan and the is broken down into 5v and 3.5v, then a 5v fan would do the trick, like this one... http://www.eagletechcomputers.com/30mmcoolingfan.html[/url]

From what I can tell, the ps2 mb uses the full 8.5V. Sure it uses 5V for the psone circuitry, but it also requires 8V.

i said 3.5v for the DVD reader.

Really Awesome

So...the 5v fan would do it, right?

If we MUST use ~8.5V, I think I should consider battery options.

7.2V battery pack and several 1.2V Recharagable batteries(1.2V ones are in parallel and attached in series with the 7.2V ones) equal 8.4V.

7 1.2V batteries connected in series equal 8.4V

Rechargable "9V" batteries.

Rewire a DC-DC Converter to somehow combine the 5 and 3.3V circuits into a single 8.3V circuit, maybe with diodes....

Try to average together 5 and 12V sources or DC-DC/ITX converter paths into 8.5V (put a 5 and 12V battery in parallel with each other) WARNING: May not work and overload the 5V battery/trace unless it has a GREAT tolerance for excessive voltage...but this would result in 8.5V if it worked by some miracle, maybe by the blessed power of diodes...

12V with a 7809 voltage regulator(5-6 in parallel or use a power transistor or two)

Rechargeble 9 volts wouldn't be a good idea, imo. from what I've seen, they're only 8.4v really, and AFAIK they've got about 140 maH to 200maH. That sucks!!! 10 of them would only be 1400 maH to 200maH and 10 is way too much space. So I think rechargeable 9v batteries are out of the picture......

Yeah I figured this out a couple of years ago when my NES wouldn't boot off a 9 volt. It's a bummer it's amps are so low otherwise it could be a standard in portabilizing.

Well, I guess we could try using 9.6V RC car batteries....but we need something to drop voltage to a level for the PS2 MkII...

I would suggest 9.6V rc batteries with a 7808 ldo, but then again, if it needs 8.5V and not 8V, you'd need to find an adjustable ldo regulator, and I'm not even sure if they make them.

Or try a 7809. I think those exist...
