If I was going to get a high wattage power supply, I'd certainly try and get a PCP&C. Unfortunately I'm a gamer on a budget lol. Cant afford to spend >$100 on PSU. Would this run two G80 GTX's in SLI?

No one will know for sure until release but I hope its enough lol. Also these psu's may not be as good as PCP&C's but they are a lot cheaper and a lot quieter. This is a very nice psu imho

yea it's hard to say, i read that supposed a single 8800gtx will draw as much as 175w, making 2 in sli draw 350w.... yikes. even if the efficiency rating on this thing is 85% which is high, that would yield ~722w peak power output. leaving around 370w for other components, which the c2d draws around 240w and the x2s draw around 255 (at full load), still leaving you with about 100w to your other components, now if you plan on going quad that's another story....:p

I'm betting it will. Thermaltake also release an 850W with 4 PCI-E connectors on it. The only diff between the 750W and the 850W is that 2 of the rails can go up to 30A a piece, even though the overall amps is still around 60.

You don't have the money to spend more than $100 on a PSU, but you can afford 2 G80s?

Well, I already purchased the 750... and so far I've heard great things about it.

Maybe on my next build, when I'll be going all out with the best of the best for every component, then will I consider a beefier PSU. :p

Oh, and Imbroglio, I believe your power consumption numbers are drastically off. I've never heard of an A64 consuming even near 200 watts- even under full load. Not sure where you got those numbers from...

200watts?! Isn't it closer to 75-90?

For the A64? No, I'm quite certain they can get up to around 130 watts, still a far cry from 200 watts though.

That is for the s754 3700 (what I have), and at 2.4 GHz it consumes around 89 watts, that's about 58 amps.

For a s939 4800 @ stock clocks, that is about 110watts and 80 amps.

Yeah, Imbroglio, your numbers are messed up there bro. ;)

According to this review at Guru3d, the 7900GTX in SLi consumes around 360 watts, and the 7600GT in SLi consumes around 198 watts.

So, let's say you are correct at the total available power with this PSU if it has an 85% rating, and the available wattage is 722 watts peak.

722 - ~ 140watts for an FX-62 = ~682 watts left over.

Now, with all the info available it seems that the 8800GTX will consume up to 225 watts. Let's pit two of them in SLi for this example.

We now have:

~682 watts - up to 450 watts (2x8800GTX's in SLi) = 232 watts left over to power your ram, your case fans, your optical drives, your hard drives, and any other accessory in your system.

That should be more than enough. Even on my power supply. Except with my rig the numbers would alter a bit as my PSU is the 750 watt version- so knock off ~100 watts.

That'd bring our number to 132 watts. Now, I don't have the FX-62, I have the 3700. So, we now have:

132 watts plus (140 - 89 ) = ~ 183 watts would be the new figure left over for the rest of the system assuming that I went with two 8800GTXs.

That would still be more than enough for a rig with dual DVD-Burners, two hard drives, and say 4 or 5 decent case fans.

Again, I'm really not sure how you got the numbers that you came up with.

here (http://enthusiast.hardocp.com/article.html?art=MTIxMyw5LCxoZW50aHVzaWFzdA==) are the numbers, for you all to see.

click on power consumption, the new lower watt x2s consume 90w idle, where the hell are your numbers coming from. before they reduced power consumption a normal x2 consume 120w at idle, IDLE being the key word.
in the link you'll notice that these numbers are being recorded by the psu and someone with a multimeter at the component. so this is power being consumed directly from the psu.

my numbers are there, and they are right, and since there are dual 12v pci-e connectors you know that the power consumption is >150, otherwise you would only need one. all my numbers are at full load, not sitting there idle barely running so that you get a bsod the second a game loads. if were wanted to use your numbers we could run 2x8800gtxs and a quad core with a 500w psu, which isn't gonna happen

and btw in one of your very own links, two 7900gtxs consume 360w at load, and seeing as how 8800gtxs consume even more, my numbers are actually a touch low, but thanks anyways.

The latest version of Extreme PSU Calculator puts the 8800 around 230Watts. Just my $.02

yikes 230:eek:

sli draws 460w, 850w psus are gonna be the new standards for sure with these things, either that or the thermaltake video psus that go inside the case will sell like hot-cakes.


edit: and after re-reading above posts, note that single core cpus consume a lot less than 2 core

edit 2: oh god, 8800gtx even more. apparently the 230 stat is at idle, it can consume as much as 321w at full load, link (http://www.dailytech.com/article.aspx?newsid=4812), holy shiznit 642w with dual 8800gtxs at full load. All the sudden buying a thermaltake video psu along with a psu >700w sounds tempting, if not a 1kwpsu... not that you would really need that much, but to provide it the cleanest power and have the best stability, those are the terms i'm speaking in

I got power requirements for the CPUs off of AMD's website, and I provided links to the exact pages listing the power consumption.

As to the 7900GTX, that is two 7900GTX's in SLi. A single consumes about half of that, about 160 watts.

And for the PSU requirements of the 8800GTX, it is not physically possible for it to consume more than 225 watts. Each PCI-e connector can only supply up to 75 watts. So, for the two connectors there is a total of 150 watts. Now, the PCI-e slot can only supply up to 75 watts as well. 150 watts from the two pci-e connectors plus 75 watts from the pci-e slot would be 225 watts max. If you went any higher there would be major problems, regardless of your PSU.

the reason they recommend 18amps on the 12v rail you are powering the card with is simple, because that rail can then supply 216w. where are you getting these 75w numbers from. hence why you need to plug in two pci-e connectors, because it needs more than 216w at IDLE. all those numbers you pulled are amd's bs IDLE numbers. not real world draw from actual components.

the reason i mentioned as to the 7900gtx in sli, is because the original question pertianed to running 8800gtxs in sli, hence i double the original wattage i had heard for the card being 175w and came up with 350w. which i then turned and said was too small because you need 2 pci-e connectors for the 8800gtx meaning they draw more power, so obviously if the 7900gtx only has 1xpci-e plug, then it must draw more than those, meaning my numbers are low because i used 7900gtx wattage numbers in sli as opposed to 8800gtx numbers in sli, which is practically double.

just the mere addition of a second pci-e connector on the card should indicate something to you about voltage levels with the card, and them being off the charts. so why are you comparing IDLE cpu numbers and a single 8800gtx to what the original question was?

I was giving an idea of what the over all system as a whole consumes.

According to your figures my s754 3700 would consume over 100 watts under full load- and that would be without an oc. If this were the case, it'd be comparable to a Prescott in regards to heat generated. And we all know that isn't the case.

Tell you what, I'm not feeling too hot right now, and am in no frame of mind to continue this debate. Though I definitely want to find out whether or not you are correct. I'm now concerned about being able to run two 8800GTSs if your numbers are accurate.

I'll pick this up sometime tomorrow, and I'll have all the appropriate info (wattage per pci-e connector and PCI-e slot, CPU power consumption under full load, etc).

Untill then, I'll just say that I do hope you are wrong...

hehe :o

hope you feel better....


i've been rethinking this for a while now. so i went over to the psu calculator, and running 8800gtxs in sli with a c2d 6600 oc'd to 3.4, recommends a 780W psu. so it does indeed look as though my numbers are correct :)
