Nvidia 9800GX2 Power Requirements

[kpo6969]

would the corsair hx620watt PSU be able to handle this card?

thinking of getting rid of my 8800GTX (in RMA to BFG after it didnt post) and getting this as it has an HDMI port

I would think so
50amps

I heard this might be good enough to run the gx2:

Hate to say this but it won't work.

There's no 6-pin nor 8-pin connectors see?

The 9800 GX2 is basically 2 8800 GT's bolted together. As it would seem a single GX2 should consume what the 8800 GT's in SLi would. But because it only has a single PCI-E slot it needs an 8 pin + a 6pin to make up for not having the PCI-E bus power like 2x 8800 GT's would.

I can only imagine how hot this thing is going to run. A person on this forum said his 7950GX2 ran at around 102c. That's enough to easily cook an egg. This thing will be horrible if they can't figure out how to control the heat, which is probably why they're taking forever to release it. They took the lazy way out instead of putting two GPUs on one PCB, like the X2 and I think it might be their folly with this card, which was the same problem with their old dual GPU design.

Also, if the requirement for an SLI capable motherboard is still required, it'd be a better idea to buy two 8800GTS G92s instead.

Ding! We have a winner

Technically if it was plugged into a PCIe2.0 slot it would only need either one 8 pin or two 6 pins, but I don't think Nvidia allows g92 cards to draw over 75W from the PCIe slot, regardless of whether or not it is 2.0 (which is capable of 150W).

Try 2 8800GTS's

 

[Hatman]

Wrong.

For example, 7950GX2 compared to 2x 79GT/GTX cards was a power god as it only consumed like 30% more. There isn't 2 of everything.


This card will be awesome for water cooling though


Also there are already options on boards to give even up to 200watts through the PCI-E2 slot.

Let me clarify:
this was stated:

I said:

What is incorrect?

 

[homerdog]

Ya, but the 8800GT and 512MB GTS are limited to drawing 75W from the slot. I think this is to ensure backwards compatibility with PCIe1.X boards. Maybe the GX2 will allow a full 150W from a 2.0 slot, but we have no reason to believe that is the case.

 

[kpo6969]

The GX2 (from what I read) would need the 6 and 8 pin. It doesn't matter till it's released (to know for sure)

 

[systemlord]

How are you going to attach a waterblock to a card thats put together like a sandwitch on toasted bread? Theres no room for that, also you can't even sepperate the two PCB's. Having to watercool a graphics card because it runs too hot from the factory is absurd. Count me out if thats the case, not a best buy by a long shot! People will just get two 9800GTX's is this pans out to be true.

 

[FrozenGpu]

Thats way underpowered there spoonboy. :lol:

if 8,212 MW is not enough, then forget it!

Can you imagine what a power surge would do to your computer, it would land on the moon. :lol:

 

[jtnstnt]

The 9800X2 also has the special chip on the card which allows the single socket sli. So even for 2.0 express users its safe to have more power for it if it needs it.
But i have heard that the card system is downclocked and there for consumes less watts.

I was thinking that i wasnt going to need a 1000Watt psu in my new pc..... guess il have to see about the 3870X2.

AMD has a list of certified PSU's for single and Crossfire cards:

http://ati.amd.com/online/certifiedpsu/index.html

Since the Antec Neo 550 I bought last Sept didn't have a 6+2 PCIe for 8 pin power, I ordered an Antec Neo 650 with a 6 pin PCIe and a 6+2. That's one of the recommended PSU's for a single 3870x2.

The total system power for it was reported at Anandtech as 290 watts and at Tom's as 309 watts, so it's less power than that reported for the 9800gx2 in this thread. The Nvidia card's bound to be a bit faster too. Nvidia will be on top until ATI comes out with the 4870 in June.

Nordic Hardware said the 4870 will be 50% faster than the 3870. That's the range of a 3870x2. If I were you, I'd wait till June. The 4870's MSRP is $299 and the 4870x2 is $499. I paid $449 for my card. If I'd have known, I'd have waited, but now that I have it, I want to enjoy it and not send it back.

word! :lol:

The word is Belkin, as in Belkin UPS. All PC's with expensive GPU's should have a UPS.

The power draw from the 9800x2 seems ridiculous for 1 card, but for a sli configuration its pretty standard. The only problem is that it is no better then sli, it is infact worse(and sli has bad scaling to boot). 2 pcbs sandwiched together is a nono. You now have heating problems and the fact that it is underclocked doesn't help either. Oh yea, it requires a eight and six pin connecter when the regular 8800gts(g92) only requires a single six pin. Sorry but the 9800x2 looks like a let down to me. But on the other hand the 9800gtx looks very promising. I am very interested in that, single pcb, better cooling, better overclocking, very powerful single gpu etc.

Still, I would love to see how well the 9800x2 does. I know it will be powerful, but I imagine it to be very problematic as well.

Believe it!

 

[systemlord]

I won't believe anything until I see how it does for myself before I judge it.

 

[Kraynor]

looks like I'm going to have to upgrade my PSU...
*calls the boss for more shifts in work next week*

 

[systemlord]

I said there was going to be an 8pin + a 6pin power connector, thats a fact.

I hope people can see what Nvidia is doing with this thing. It is nice for those of us like me to be able to get the power of dual gpu's on a mobo that does not support sli, but waiting until ATI releases their new cards, or even waiting for Nvidia to release their REAL next gen cards is the only logical this to do. This card is just to feed Nvidia more money until that time comes later this year.

This just seems too power-hungry and rushed-to-market to be a wise purchase. ATI's dual gpu card is easily the better design in every sense of the matter. For $609, a 3870 X2 ($430 @ Newegg) and a 3870 ($179 @ Newegg) can be had. We won't know until this gets released, but I am pretty sure those 2 cards will kick this thing's ass.

I can't wait for the overheating blunders to come pouring in to the forums :lol:

 

[yipsl]

It's been floating around that the GX2 card releasing next month will have a minimum requirement of 580W. This seems a little rediculous to me, but since it is 2xGPU's in one I suppose it's possible. Does this mean you should be getting AT LEAST a 700W PSU if planning to buy this?

That doesn't sound ridiculous. My 3870x2 needs a minimum of 550 watts with one six pin and one 8 pin PCIe power connectors. With these cards, you're basically getting SLI/Crossfire in one slot (though the 9800gx2's solution lacks elegance -- Nvidia could have done one PCB, why didn't they?).

 

[Iscabis]

They might have not banked on ATI doing a dual gpu card. That would make sense. Their design was good enough before, so why change it? Their design is not completely bad, but when compared to ATI's design it is.

Nvidia was probably not expecting ATI to give them any competition. If that is what they were thinking, they were wrong.

 

[Annisman]

Dam Nvidia, if I didn't have a 680i, I would be picking up the 3870X2, and another 3870 for CF. Dam you Nvidia.
