mini-itx 780G board

I am thinking about purchasing this board, but what is the fastest capable chip you can put into one of these? The recommended TDP is 65 is that really the highest it can go?

Say with water cooling what is the fastest chip you could pair with this board?

Parts:

Nexus Psile case - white/aluminum
J&W 780G mini itx
4 GB DDR2
WD green cavier 500GB SATA
picopsu 120 w/ 110 watt AC/DC brick
AMD Athlon X2 4850
Windows XP
Scythe ninja mini
92 mm fan

Not the easiest build. The case comes with IDE DVD drive w/ standard 80pin cable. Unfortunately the power connector is right next to IDE connector on the motherboard and the picopsu doesn't fit well with the IDE cable in place. I might have been able to jam it in. Instead I just bought a 20-24 ATX converter. The motherboard manaul says it would work w/ just a 20 pin connector. Also had to buy a P4 power cable. The power supply is just dangling on a plastic hook I mounted inside the case. Works fine. The case has mounts for a small board DC power supply if you can find one that fits.

I have a dumb question. What do you use the P4 power cable for? I'm just starting this same build now and I'm struggling with it. I see the picoPSU has the 20 pin ATX connector, a 4 pin Berg connector (I think...which connects to the slim internal dvd-rom?), an SATA connector (for hard drive I presume), and finally it has a 4-pin molex connector. Is that what this P4 power cable is for - to connect with the 4-pin molex? What do I need to hook this up to? Perhaps the case fans? The motherboard should have enough fan connectors for case fans, shouldn't it?

Thanks for your help! It's been a while since I put together a rig, so I'm having a hard time catching up with the newer standards.

Around the debut of the Pentium 4, CPU started requiring far more power than they had in the past. This lead to motherboard manufacturers including an additional 4-pin connection between the PSU and MB. Pretty much any socket-based motherboard you buy these days will have it. Depending on what CPU you use, it is not always necessary to make this connection. The P4 cable he is talking about is just an adapter between standard 4-pin molex and this connection -- it is used since the PicoPSU model he has does not natively come with a P4 output.

Thanks for the quick reply! I have the exact same setup as gtguan, which is a j&w minix 780g mobo and an AMD 4850e cpu. Does this mean that it won't power on unless I have a P4 cable connected between the picoPSU and the motherboard?

Maybe I need to ask when is a P4 connection needed? Will a Core i7 920 cpu need it with an X58 motherboard?

It's needed with almost any modern board. An i7 will absolutely need one. Probably an 8-pin on most boards.

I got stuck again trying to finish this build even though I'm in the final stages. I've posted a new thread in the Systems Advice forum: viewtopic.php?p=471208#471208

Anyone see gtguan post on the forums lately? Hope someone else can help me out!

i wonder hows the new Minix 785G is going... we aret heard anything since Computex 2009 about it.
