6800, and PSU

[M3ltd0Vvn]

Sort of OT, but informitive none-the-less:

Which I got from a post I made a few months back asking a "similar" question.

Basicly gives info on what is needed on what rail. Most you probably know this allready, but for those {like me} that wonder why we speak of 12v, 5v, and 3.3v these links answer it.

Besudes, some people won't even buy ATI, and likewise, some people won't buy nVidia, so there.

are there any signs that the X800 will not stack up with the 6800U? if so, please post some leads. otherwise, i assume this is all speculation

back on topic, the TT is an excellent PSU. just read some of the reviews that newegg has linked to. @ $60 its a steal.

 

[stardust]

I think something with active PFC would be more stable. I bought a TT 420W w/ PFC... we shall see if it will run an OC'ed A64, 2 harddrives, audigy2, AND a 6800 If not, I guess I'm going to have to buy 500W...

My electricity bill will just keep on rising!

Also, you will only need that if you are going to spring for the ultra. I am sure that the $299 part and the midrange derivation when it comes out will not have that burly of power requirements.

Thank you, Rudee had that coming

Ugh. I want to build a new system now with an Antec Sonata case that comes with a 380watt True Power PSU. I'm guess that's really enough, since the 6800 Ultra dosen't really draw much more than current cards, but it would really suck to have to drop another $100 on a PSU in a month.

EDIT: Just checked, and my current Antec True Power 380 supplies 18amps on the 12 volt rail...which I guess is good, since some of the 450PSUs in that article don't supply that much. Man this is getting confusing. Now we can't even just make sure our PSUs have enough watts, we've got to be concerned with efficency, power on different rails, etc. This hobby really sucks time

EDIT2: The True Power 480 supplies 22amps on the 12 volt. An extra 4 amps...not TOO worried about that.

PWNED my a$$. My posts on these issues go back days, not weeks, not years. You have no clue what a fanboy truly is.

 

[Acanthus]

As for the power/heat issue, its a trend with all computer components.

Oh no! My memory needs a heatspreader!

Oh no! Look at that giant HSF!

Oh no! More than 100w power consumption on my cpu!

Oh no! 2 slot coolers on my graphics card!

Oh no! 3 fans in my power supply!

Oh no! High case temps!
--------------------------------------------------------------------------------------------------

More performance = more heat and more power consumption. Seriously, get over it.

Edit:

I mean just think about it logically, you want a card with a chip bigger than a P4EE AND 256-512MB of memory to consume less power and be cooled by a heatsink 1" tall?

Even in light of all the amazing results the NV40 has produced, you have had not one good thing to say about it. Just bad things that are unfounded.

Thanks again and keep up the good work!

A simple search for keysplayr2003's posts in the video Form make your post reek of irony. Beautiful!!

 

[Godofmosquitos]

It doesn't make sense. look at Toms and Techreports conclusions about power. It doesn't add up. That much higher load (24W) does_not_justify_recommending_a_480W_PSU_!_FFS_!!! It has to be a worst case scenario. "In case you have a cheap PSU and because we know most ppl just don't HAVE 2 dedicated molex's for our card we highly recommend u use a 480W PSU when using our new card. Just to be on the safe side. If you however HAVE a good PSU (good 300W PSU's perform far better than cheap 400W etc) and can connect dedicated cables to our chip, u shouldn't have a problem". I mean, otherwise it doesn't make sense. U saw the watt requirements in the review. It doesn't justify going up to a 480W PSU. I dare Anandtech to try and see what PSU's they can make the card run on. Take three expensive from 350W up and three cheap from 350W up and see if they can make the card run without probs.

I must admit, I have my moments. But just so you know, my 11 year old neice is profoundly deaf and a little autistic, therefore she does need
to take the short bus to school.. I only pray that nobody you love has to do the same.

 

[DoobieOnline]

Hey Sneaky, check this one out: Tagan 480W

It was recommended by Tates and after seeing the 6800 review today I jumped. Based on some of the reviews I've seen, it's one of the best psu's you can get for <100 clams. Strong rails, plenty of leads, and excellent build quality. It should definitely keep the 6800 happy.

Besudes, some people won't even buy ATI, and likewise, some people won't buy nVidia, so there.

actually it is stacking up in their favour.

600/1200 presumed clock speeds with 16 pipelines vs. 400/1100 and 16 pipelines for Nvidia

This would mean that Nvidia's efficiency per clock cycle must be at least 50% better than ATIs just to equal the performance of the GPU alone.

Even though ATI is going to use an older architectue I doubt Nvidia does 50% more work per clock cycle in comparison to a 9800Pro/XT. Look at the benchmarks, NV40 beats 9800xt by 2x at most things. Now ATI will double the pipelines, and increase the clock speeds from 412 to 600 or about 45% thus making the theoretical fillrate already double that of 9800xt with pipelines alone. With a much faster GPU this is going to definately give ATI an edge on paper if these specs are true.

I am not saying this will translate to real world performance, but on paper ATI seems like a faster GPU. That is my opinion of course so if you think otherwise let me know.

 

[klah]

Go read sfftech's Shuttle XPC review. 3.2E and 9800Pro on a 250W PSU and it works fine. From the tests I've seen today, the 6800U only uses 10-25W more than current cards.

Did Nvidia actually release a statement mentioning this 480W figure, or is it just something they suggested to reviewers?

60 to 80 million extra transistors maybe?

It is rumoured to have 160~180m transistors in total.
The NV40 has 220~.
Both made with a similar process (or same), so it would be logical to assume that the ATi product will have at most the same power requirements.

It's not the same.. ATI is low-k and using less transistors. It's been said all over the place that the 420 looks exactly like the 9800XT and only requires one molex.

Keys, you started the name calling. And what?s with the FB documentation ?.Yiks ? you must have better things to do..right ????

The guys just speculating based on what we know so far.

How did you reach that conclusion? link?

It?s not a ?conclusion? ?.he said chances are?.

And I would agree. The NV40 is 222 million transistors. The info on the R420 is ~ 180 million -- plus the R420 is going to be using a 0.13 low-k process. If the low power consumption and cool running of the 9600XT is any indication, this low-k process could give ATI a sizable advantage. The downside for power consumption for the R420 is that it will probably be running a higher clock rate than the NV40.

I think it?s very likely the R420 will consume less power than the 6800, how much less remains to be seen.

Well, what would you call him blast? Every post I see from the guy trashes NV40 somehow. I will buy the R420 if it is faster than the
NV40. So, although this is all very kewl competition, I just want the best one out of the bunch. I have never splurged and bought the Ultra high
end card at the time, but this time I think I will treat myself to a shiny new titan and a nasty PSU. So I didn't start it Blast. I would have left him well alone. I don't just call someone a fanboy without reason.

that enermax has 26A on the 12V line... and at 350W too. Look for a strong 12V line.

Enermax always overrates their PS. Don't believe those numbers.

From what i've seen the Tagan is prolly the best PS you can buy. If u really need it, thats another question.

Some of the people who are complaining that the 6800 ultra might require them to get a better psu are just stupid. If someone can afford to buy the 6800 ultra then getting a new psu if you need one isn't going to break the bank! :disgust:

I meant over the current high end ATI cards. R3xx has 107 million, thats my guess why power requirements could go up for the next gen Radeon cards.
