I'm looking for specs on the new 9xxx series to determine if I would need to upgrade my PSU and mobo.

Any info?

It depends on which video card you get. Likely though, as long as you stay with one video card, you will always have way more than enough power. It's very overkill the way it is.

Your PSU is just very average nothing wrong with it other then its very loud at high loads

It's a SeaSonic S12II just like the 620W Antec High Current Gamer, but with slightly inferior components (that's the best that I can remember).

The review called it average and loud but nothing other then that

Might be one of those famous IBM concrete fans it has

Ooo, a fan made from concrete!

hehe

Anyway, even so, it has a +12V capacity of 576W (48A) which is much more than enough for any typical single-card setup.

You dont know that old joke?

Back when i was a kid my dad would always say IBM made their fans out of concrete

Think that was back in the early-mid 90´s

It must not have made its way across the pond. lol

Although, I wasn't into computers back then. I liked them, but I didn't know anything about them.

Got my first PC when i was 3 years old

Thats was 24 years ago (well almost turn 27 in 3 weeks)

Anyway off topic

Amps on the 12v rail(s) is the most important issue. Second is if there is a connector compatibility problem, such as only have 6pin when you need 8pin or 20pin when you need 24 pin. But that can be fixed with a simple bridge from spare cable. The two additional pins are both ground in the case of PCIe power connector.

Your PSU is more than enough.

I'm assuming you're guessing. 7950 requires 500W, 7990 requires 750W. logically speaking, 99xx should need 950W or greater but then again AMD is known for GPUs with low relative power consumption. Unfortunately there's no early scoop on the 99xx's power req. I guess we have to wait and see because no one knows really for sure.

Newer hardware use less power not more

You almost never see newer hardware use more power its almost unheard of

We are actually talking about graphics cards.

Yes thats still hardware

They are not going to use more power

Before I say anything, I want to point out that this thread is not asking about the 99xx series, but it's asking about the entire 9000 Series.

Anyway, the 7990's 750W power supply requirement is due to the fact that the card is two 7970 GHz Edition GPUs on one PCB.

Also, don't take the power supply requirements literally because they are for peak-rated PSUs, not continuous-rated PSUs. I don't know of any peak-rated PSUs that are recommendable.

So, peak-rated vs. continuous-rated: take the 500W PSU requirement. The typical 500W peak-rated PSU is going to have a +12V capacity of about 360W, or 30A. There are good 400W PSU's that have that +12V capacity (some even have 396W). Then, take the 750W PSU requirement. The typical 750W peak-rated PSU is going to have a +12V capacity of 504-576W (or 42-48A). There are decent 550W PSUs that have a +12V capacity of 504W, and there are decent 650W PSUs that have a +12V capacity of 576W.

As for AMD being known for GPUs with relatively low power consumption, that's not what I've found with their most recent offerings. Compare the power consumption card-for-card between AMD and NVIDIA in their latest offerings (excluding the GeForce 700 Series because that will be compared to the retail 8000 Series), and you'll find that NVIDIA's GeForce 600 Series GPUs have a lower power consumption than AMD's 7000 Series, GPU-for-GPU. Just as an example, the 7970 vs. the GTX 680:

http://www.guru3d.com/articles_pages/amd_radeon_hd_7970_review,8.html

http://www.guru3d.com/articles_pages/geforce_gtx_680_review,9.html

Ignore their recommendations for a power supply capacity because they too are talking about peak-rated PSUs. For now, just compare the power consumption differences between these two.

However, take a look at the previous generations:

http://www.guru3d.com/articles_pages/radeon_6950_6970_review,11.html

http://www.guru3d.com/articles_pages/geforce_gtx_580_review,7.html

Both consume more power than their newer counterparts (the newer generation requires less power than the older generations), but here we see the GTX 580 requiring more power than the 6970. I won't say that this is predicting the future of how they will compare due to how it seems to be reversing where NVIDIA has lower power consumption, but at least right now this is what we're seeing. However, when the 9000 Series equivalent to the 7990 comes out, I sincerely doubt that they will be recommending a 950W peak-rated PSU! Even if they did, then that would still mean a good quality-made (i.e. continuous-rated) 750W PSU as opposed to the good quality-made 650W PSU that you can use today for a system with one 7990 in it.

Therefore, as long as he stays away from the equivalent of the 7990, his PSU should be more than enough, even if he were to get the equivalent to the 7970.

And I know you don't know that the power ratings that AMD and Nvidia for their cards are at best can be construed as suggestions. I don't need to speak on this further as Twocables posted the logic. There is 48 amps~ on your 12v rail for your PSU. You are not a Vulcan, k?

TY Twocables.

I don't know what you're talking about. What's a Vulcan, aside from Star Trek?
