I agree with you. I find it very hard to believe that a 600W dual rail powersupply would not be able to run a single G80.

On multi-rail PSU's, yes. Not on single-rails, however, which means that if you had a single-rail with 38A you could still use whatever leftover power the processor doesn't take for the rest of your components. This is why dual-rail PSU's are inferior to single-rail PSU's. ATX standards specify no more than about 22A/per rail on multi-rail PSU's. That means on a dual-rail PSU you will have at most 22A to run every component but your CPU off of that takes power from the 12v rail (optical drives, hard drives, case fans, leds, sound card, graphics card, etc).

Unless you are going tri or quad-rail, it is better to go for a strong single-rail PSU.

And whoever asked me about the Silverstone ST56ZF (sorry, I don't remember who you were) -- yes. It would have no problem running an 8800GTX.

I really hope a 400w psu be enough to run a single GTS.

well i run 3HDDs 1 S-ATA 2 S-ATA II on S-ata controllers
X-Fi xtreme music
1optical drive
A64 3700+
1024mb ram dont know if these use power

and a ASUS 7900GTX

no BSods yet had it a few days

all this on a 480W PSU

so perhaps it can run a 8800 with 2 HDDs

well if i buy it and probalby wont in a while

ill deal with the PSu issue then


but 2 in SLI would be so cool

Since everyone is arguing about PSU requirements and wether it would run, I thought I'd chime in with my two cents. Back when I got X1900's in X-Fire, there were debates as to what PSU's could or couldn't run them. What it came down to was not how many rails you had but how well it was built. I run two X1900s in X-Fire with a PC Power and Cooling 510 Watt PSU and it runs fine, yet in some reviews the Tri rail 750 watt POS PSU's wouldn't even start an X1900 Cross Fire setup.

So yes it sounds like G80 is going to be a beast and I would imagine for SLI you need a good 750 Watt PSU or better for 8800GTXs in SLI. I would how ever go with quality over quantity, if you get a junk PSU it can have all the 12V rails you want it to have or what ever and it still won't run 8800GTX's in SLI. As to the debate about a 510 running 8800's, I bet it would run one just fine. At least I know my PC P&C 510 will.

That's unfortunate, because now I'd put you in the same boat as mike686. Might want to look into a new PSU. Dual-rail PSU's are horribly optimized for gaming, and the reason is because your graphics are almost always sharing resources with other devices in your computer, and with a card that's going to take up as many amps as 8800GTX will (15A+, most likely) it doesn't leave you a lot of breathing room (3-5A) on either one of those rails.

you have the most flawed calculation ever. Consider if 8800GTX really draws 15A from 12V line, that is 15X12 = 180W right there, and if it also draws the full 75W from PCI-E slot, we're talking about 225W in total just for the graphic card. That number is ridiculous since 7950GX2 (and that is over 540million transistor count with 1gb of ram) only takes around 140W. Consider a linear increase in power with respect to transistor count (and not taking into acct that GX2 has more ram etc), G80 should consume around 180W. 15A+ current draw is just not true.

And to quote you again:

So let's consider the amp distribution in Average Joe's computer and see if the #'s add up.

1) Your hard drive(s). 1 HDD ~2A

2) Your optical drive(s). 2 drives ~3A

3) Your motherboard/memory. ~2-3A

4) Your case fan(s). 2-3 fans ~ 2A

5) Your sound card. ~ 2A

Total amps available on 12v2: 19A
Total amps used in this equation: 12
Total amps left for graphics: 7
now that is just retarded. To say 19 friggin amps goes straight to your processor is wrong. Even if you use a Pentium 840 EE, which is probably one of the hottest processors, consumes around 150W stock. Let's say you have it overclocked madly, and it consumes 200W. Well if it only draws from 12V rail, that is 16 to 17 amp, and that's assume power draw from 5V and 3V is zero. And that's worst case possible. Both Athlon64 X2 and C2D's power usage is a lot lower than 840EE.

and how did you know a Hdd draws 2amps from 12V rail?? Well the truth is a HDD uses aound 10W in total power, and not all of it comes from 12V. Same goes to your optical drive (which only draws some power when it spins up), and your fan draw 2amp?? Well, as far as I know, a 92mm tornado will draw 1amp, but how many ppl runs 2 tornadoes in their case?? Most fans draw max of 4 watt. A 120x120x38 panaflo medium at 2100 rpm draws about 340 MILLIamp.

For a system with 955EE, 2X7800GTX512, 1gb of ram, 2 hdd in raid0, under 3dmark06 takes 310W DC output.
http://www.pcper.com/article.php?aid...e=expert&pid=3

and in the end, let's consider Mike's system listed in his sig:
AMD 4000+ | Zalman 120mm | MSI K8N Neo4 Platinum SLI | OCZ Platinum PC3200 2x1GB | eVGA 7800GT | WD Caviar 250GBx2 (Raid 0) | Antec NeoPower 480 | MGE Titanium Case

AMD4000+: 90W max. PCIE connector for 8800GTX: 75W, assume that's all from 12V line: 165W / 12V = 13.75A.

ram, HDD and all the fans, let's make it big: 50W and assume all the power is from 12V line. So that gives: 50W / 12V = 4.2A.

and let's add 2 optical drive running at full speed all the time: 25W / 12V = 2.1A

Add one 8800GTX, let's say it draws 200W only from 12V line alone, subtract 75W from the mobo, that gives 125W / 12V = 10.5A.

Guess what, the Antec NeoPower 480 with dual 12V rail at 19amps each is plenty!

JoKer--I never said that the CPU itself takes up 19A. I said that it has its own dedicated rail on dual-rail PSU's, which it does. It's the way dual-rail PSU's are designed; you cannot use rail #1 for anything but your processor. I spelled that out rather explicitly and explained it's the reason why dual-rail PSU's are inferior to single-rail. Whether a processor would take 19A or not, it doesn't matter. The first 12v rail is not designed to provide amps to any other components. Therefore, any excess amperage cannot be used.

Okay, with this little PSU argument going on, I'm seeing only a couple possible outcomes:

1.) Xion is correct, and those with weaker PSU (less amps than necessary) try running a GTX and end up with an unstable system, or damaging a compnent (hopefully not their new 8800GTX ).

2.) Xion is wrong, and people with weaker PSUs can run an 8800GTX just fine. This would mean that the 8800GTX would have to consume less power than predicted.

Me, I'm hoping for the second, as that would then mean I could run dual 8800GTXs without having to sacrifice any other components in my rig.

But, if Xion does end up correct, then I will still be capable of running two 8800GTS's no problem.

In all honesty, I find it kind of odd that people willing to shell out well over $500 for a video card are complaining about having to spend a little over $100 for a decent PSU. This logic seems completely @$$ backwards as the PSU is, without possible argument, the most important and critical component in your computer.

It only seems logical, that after dumping down so much money on just a single graphics card, you would have no problem getting a PSU that is guaranteed to run the card and the rest of your system just fine.

Atleast, that is the stance I took. And one way or another it is going to pay off, either in dual GTS's or dual GTXs. Right now, I'm going for the dual GTS's as it seems Xion's arguments do add up.
