Computex 2004 Update: More NV45 Information

The mysterious power connector still puzzles us, and in fact it seems to be puzzling most add-in card partners as well. We are still working on finding out exactly what plugs into this port and what sort of voltage/current it will deliver and where it will get it from. Until then, here's some gratuitous photography:
And finally, some of you have asked about the connector at the top of NV45. We're not certain about its role either, but we have some meetings scheduled for today that may help clear that up.
Another change we noticed was this heatsink over some of the power circuitry on NV45:
Keep checking back, there's much more information coming, including a very interesting rumor we're following up on involving VIA and their AGP/PCI lock...

Could the 6-pin plug be part of the BTX specification, or am I getting my specifications confused?Icewind - Tuesday, June 1, 2004 - link
Ok, im officially confused. WTF is Nvidia trying to accomplish with this. NOW we have to buy a new PSU to support this power connector?Sigh, i'll be sticking with good old maple leave ATi I think.

It's a power connector.3 pins for +12V, 2 gnd pins, & one sense pin. According to PCI-E spec, graphic card consumes more than 75W need this power connector.

Looks like a 3 phase molex power conn.DoctorM - Tuesday, June 1, 2004 - link
Doh, you're right it's 6-pins not 4 like on the +12v line.A 6-pin auxillary connector could deliver the power needed with an adapter cable, but why would you change the connection if it's already part of the ATX standard (v2.03 I believe.)
Wasn't that originally developed as an aditional AGP power connection?
Ok, so I'm officially stumped (and stupid for the previous 4-pin conjecture).

If they can standardize the plug and make an adapter for old hardware I'll be OK with it. Otherwise...Chuckles - Monday, May 31, 2004 - link
I just noticed something rather interesting regarding the 6-pin power connector.ATI's partner PCI-E cards have the mounting holes for a similar power plug on their cards, as illustrated in the following picture:

Notice the holes in the upper right-hand corner of the card.

Call me crazy, but that extra power connector looks just like the +12v Atx power connector on motherboards.That would explain the need for a big heat sink, there's probably a power transformer underneath.
Looks like the double 4-pin molex thing wasn't enough.
Now where can I get a Y-connector.

who is computex's targetted audiance? why is it held in taiwan?
