How much power does it take on each connection of the GTX 280
 
It has a 8pin PCI express and a 6pin Express connector .how much power or watts does each connection use.

If know one knows the answer to that question ,Do you know how much the main GTX280 uses and how much the slave or secound GTX280 uses.I would think the slave or secound one would use less power then the main one.I just want to know what the card needs in power not none of the other componets .I have read somewhere that it uses 237watts under load ,just the card nothing else,and other places say 330watts.I still don;t under why it need a 8pin Express if the two extra pins are negative.

pci-e (slot) = 75w
pci-e 2.0 (slot) =150w
6-pin =75w / 108w??
8-pin=150w

These numbers are from random googling and are the complete opposite of the question you are asking :)

Nvidia says 236w

How many 8 pin pci-e plugs do you have , Are you using a converter that connects 2 gnd leads to fool the card?

I have no idea whats going on ,I just like typing:headexplode:

what are your PSU specs?

That is one of the main questions I wanted a answer for ,how much power each connector needed or used.I was always just curious of the 8pin PCIe because I would have thought it use a extra 12v plug instead of just two added negative plugs.I don't understand how it provides more power ,It looks to me that a 6pin PCIe would be enough if they are not useing no more 12v lines.I was'nt going to use two GTX280 in SLI ,I never had any problems with my 8800GTS 640mb running in SLI.It is going to be my Birthday on the 18 of this month and my mother surprised me and bought me a GTX280 ,so I guess I will run SLI this time to.I have a SilverStone OP650watt that has 54amps on the 12v rail ,I will be useing that to power my secound GTX280 or the Slave one and one the main GTX280 I will be useing a 450watt(550watt Peak) Thermaltake ToughPower VGA PowerExpress that has 38amps (46amps Peak) so all together I should have around 92amps for my system.All the reviews I have seen have been good on the TT 450watt VGA Epress.One guy is running both of his GTX280's on it and he says he has'nt had one problem and others that are running two GTX280's have not had any problems either,but they are just running one off it and the other off there main power supply,so I am hoping I don't .It comes with a 5 year warranty and it is just $69.It saved me over $200 not haveing to buy a bigger power supply.It looks like a good setup ,they even have a 650watt version for $109 but it is twice as big and I did'nt need that much more power.I will have Three 8pin PCIe and Four 6pin PCIe.I will not be useing no adaptors.

Dude. Its called an enter button. It creates paragraphs. Learn it, use it. Thanks.

You question the 2 negative pins but use a double negative yourself,

Oh the irony. j/k

They made a new one (TT) ,Thats great, Kinda pricey though over here.

The 450w version would be a little short sighted.

Where are you seeing official documentation that pci-2 2.0 is 150 watt (vs. 75 watt for pci 1.0). I see a post here and there by random people (such as yourself) claiming pci-e 2.0 provides 150 watts of power, but official pci-e 2.0 spec pages make no mention of this, as best I can tell.
