As far as I know the PC P&C's 850W/1KW offerings are the only PSUs with true multiple 12V lines.

The multi-rail thing really tended to hurt performance anyway; many overclockers didn't find the same stability on the "lower-amp-more-rails" PSUs than the high-amp-single-rails.
So if I have two Ultra X-connect 500w PSUs with 34amps on the 12 volt rails, one for CPU's, other for video cards that comes up to a much cheaper solution (about 80$ from FS FT).
If the 34 amps for the graphics won't work for the GPUs, then the third rail (36amp) on the PC P&C won't work either. Then I can always take one adapter from the CPU PSU (2x 6-pin adapters on each card, right?) and split the load a little more. Either way, I see no reason to spend 500$ on the PC P&C PSUs. Even then, if you wanted to absolute ensure operation, get a third 500W PSU bring the total up to 120 with 3 rails each 34 amps. Definitely much better performance than the 500$ one.

I do agree that it will probably be pretty rare, since most people don't have cases that support two PSUs and water cooling probably will be required.

I get what you're saying but I don't think I'd compare two 500W Ultra's to a 1kw PC P&C. There is a drastic difference in quality and stability. A pair of high quality 400-500W PSU's would still be cheaper than a 800-1000W beast but it wouldn't be as drastic as you were making it to be.

I sure hope the new cards don't take anything too crazy in the way of power requirements. I was hoping 600W would be enough for a long while yet but looks like that might not be the case.

Added anti-aliasing info. (X16 AA and VCAA) Has anyone figured out what the hell VCAA is? So far there have been deciphers like:

Very Correct Anti-Aliasing
Virtually Correct Anti-Aliasing
Virgin Cathy Anti-Aliasing
Vagina-Cock Anti-Alasing

OK I'll stop. :D

What is this about needing a 1kw PSU and water cooling to run SLI G80? From what I've read, it will be around the same power requirement as X1950XTX Crossfire, with each 8800GTX drawing more than a 7900GTX but not significantly (don't have numbers here). An OCZ 600-700W will be fine for SLI, I'd be shocked if you even needed 600W in an average system (cpu, ram, SLI 8800, 2 HDD, one optical, 2 case fans).

Which makes sense since the point of multiple rails was nothing but to meet the requirements of ATX 2.0 specification, which says that the 12V line must not execeed a current of 18A. Yes, most PSU's with multiple 12V rails have all the 12V rails on one line, but the rails aren't individual sources, they are rather from the same line, just each one is restricted to 18A (or whatever for that particular PSU, most are 18A though). I think the intent was to prevent fires since computers can often be opened in a home or business.

Hmmm, what brands of high quality PSUs are you referring to? In most benchmarks the X-Connect 500W looks to be just as stable as antec, enermax, seasonic, etc, etc. The only thing I can find fault on it would be the 20 pin ATX adapter. The Sunbeam NUUO was a great power supply too, but no one noticed it either. I remember when OCZ ram was overlooked as well. The X-Connect is a quality PSU, and if by "high quality" you are referring to the enermax, antec, etc field, then the Ultra PSUs do exceptionally well fitting into this category.

Apologies to the OP and the topic for going off topic a bit.

PC Power & Cooling has been mentioned by name in a few posts. PCP&C PSU's are widely regarded to be amoung the best PSU's available. Antec, Enermax, Tagan, FSG, and Seasonic and a few others are all quality PSU's, but PCP&C is the top and you pay a premium for their PSU's. There are a few PSU makers that are equally regarded, such as Zippy, but they generally don't focus on the gamer market like PCP&C. Honestly, if you really want to get the lowdown on PSU's look for posts by JohhyGuru. Or check out his website: http://www.jonnyguru.com/forums/showthread.php?t=103

Anyway, back on topic, apopin posted this in the other G80 thread:

http://www.theinquirer.net/default.aspx?article=35061

...might want to add that to the first post.

Im sure AT has both the upcoming nforce 680i mobo and G80. If you go to the motherboard section of AT, AT editor Gary Key pretty much says this.

They are benching the G80 at this very moment. I know it! :D

Give us some numbers!!!

Thank you. Adding as of now.
Also confirmed is the new demo for G80 honors the beauty of Rosie O'donnelle.. Oops or Adrianne Curry.

First sign of G80 performance has been leaked. The credibility of this image is as blurry as the image itself, but it nonetheless mimicks the usual graph you can find in the back of retail box of many GeForce products. It states the 8800 series' performance as x27 of on-board video compared to x20 of that of 7900 series. I am very confused. :confused:

It's simple math, really. Integrated graphics give you the starting point, or 1x the performance. Say you get 20 frames per second with integrated, you'll get 540 frames per second with an 8800. :D ;)

Nevermind. On a close inspect, the graphs are obviously 'chopped. And I can't think of G80's performance being that low compared to G71. I removed the bits from the first post.

You know if you waited till few more months after its launch or even till march then you could buy the more updated version like 8900GTS at lower price and higher performance :(

And if you wait even longer, you will probably be able to pick up a 9-series card for cheap also...

That motherboard is pretty nice looking. I am, however, a bit puzzled by the spacing of the PCIe slots since they only have one slot between them...

I'm sorry, where does it say 7950? The images are quite probably out of thin air, but as usual nothing is taboo when you obfuscate the truth :p .

7900GPUs = G71.

7950GX2 uses 2 x G71 cores. Hence you can say 7950GPUs are 7900GPUs since they use the same core.

Btw those performance graphs are always wrong. Remember the initial R520 graphs?

That's asinine. By your logic, a 8 or 16-core Nvidia enterprise or beta test card would be fair game to put on the back of the box under the "7900" category, since those cards would simply have 8 or 16 7900 GPU's to go with a few gigs of GDDR.


A 7950 is not a 7900; yes they use the same core architecture but they have different model numbers for a reason. One of them has two GPU's. See, I can be condescending too ;) .

Heh... They were quite accurate... nowadays a x1800xt spanks a 7800gtx flat

QFT. A 7900GT was always in competition with the X1800XT. How many threads did we have when someone was wanting one of those cards again? There for a while it seemed like that's all anyone was asking. 7900GT or X1800XT? Needless to say, the X1800XT got the nod more often then not for many reasons.

I hardly saw a difference when I went from my P4 1.8Ghz 400bus to my P4 3.0ghz 800bus. But saw a massive difference when I went from my 5900 to my 6800.

My best friend has the exact same setup as my new system except he has the E6300 and I have the E6600, his score is 100 less then mine (4320 on mine vs 4218 on his) on Geforce 7900GS's.

DX10 has said it will remove even more work off the CPU and put it on the GPU... I think this is supported with why the Memory amounts have increased so big all of a sudden.

Hell, fvck that. Wait even a couple of refreshes more, and you'll be able to pick up the 8950GTX quadcore card for pretty darned cheap on eBay.

Always look forward, never buy now, that's my philosophy in purchasing computer equipment..............
