As the launch draws near, NVIDIA's partners are busy readying retail boxes.
NVIDIA remains tight-lipped over the card's specifications, but we can confirm from the box that it will have 1,536MB of GDDR5 memory.
The power requirements are such that it needs more juice than twin 6-pin plugs can supply, and the setup is the same as a Radeon HD 5970's.
A chunky PSU is recommended, pitching in at 600W - 42A on the 12V line - for a single-GPU system. Add at least 250W for a second card.
Now all we need is a card to test NVIDIA's claims of upcoming high-end graphics hegemony.

Well I would say 600 watts for a single card system is quite high considering a crossfire setup from ATi that has two of the latest GPU chips asks for the same. Either Nvidia are being extra conservative with their figures like LuckyNV said or their cards are considerably more power hungry for very little tangible benefit.
Well my whole system consumes 300W at full load, CPU and GFX card. And that's at the wall. So say my PSU is 85% efficient, we're talking about 260W for the full system. And it's saying I need a 550W. Yeah, they're just giving shed-loads of headroom on their statement.Quote
I was under the opposite impression - that the 480 was definitely going to have a 384bit bus.
I thought that was already known ... a supposed Fermi unit with 1GB RAM must be a fake ... as a consequence of the 384 bit bus ...
As with Snooty, the 384bit interface has been known for a while.
Fair enough - memory fail on my part then I guess ;) I had it in mind that the 480 was going to be 448bit and the 460 384bit - can't remember where I thought I saw that now though! :mrgreen:Quote

Don't forget everyone in this thread probably spent more than £30 on their psu, and the purchasing decision involved more than just looking at the big number next to the W. 85% might be a dim and distant dream for some PSU's out there :)
I really hope Nvidia are just covering themselves for those people that bought cheap ass PSU's though - otherwise things are getting a little bit silly. At least with the ATI 5xxx series the idle draw was a huge improvement, even if the load figures were higher than the 4xxx's (iirc).Quote
Irritating they arent supporting displayport. And minihdmi? urgh. thats going to be a bitch to secure properly.Quote
Am I the only one who finds that power draw questionably high? It's 100 watt above the minimum for a 5870, and is on par with a crossfire setup of two of them.
You are not, the power draw is ridiculous.Quote
