GTX280/260 power requirements

PCinlife.com managed to get a screenshot of the Nvidia GTX 200 installation guide showing the recommend power requirements:
(for comparison the 9800GTX recommended 450W and 24A and 8800Ultra recommended 500W and 34A)

^ crap

i don't think i have 40 A....

thats really annoying... its a new power supply to... got t after my old one quit working =( very very annoying

actually... I have 4 12v rails... 2 with 30 A and 2 with 18 A... would it work?

Reply to thogrom

Probably; 40A is for the entire PC - not just the video card.
List the make and model and someone should be able to tell you for sure. Have an 8pin PCI-e connector?

Reply to WR2

yes

Reply to jaydeejohn

Yes if you connect two pcie 6pin connector from the two strongest rails to the card.
Maybe someone can explain beter? >.<

I am so NOT buying these cards.

Reply to HyperBladeST

40A is reccommended for an entire system, with LOTS of periphials.

Hmmm...I'll wait for the 55mm fab, that shouldn't be as power hungry.

Well, crap, I just bought a new PSU for this card, and it doesn't have an 8-pin connector or 40A... Any recommendations as to what PSU I should get? Guess I am sending this one back when it gets here tomorrow: http://www.newegg.com/Product/Prod [...] SXS%2b600W

Kyle, I don't know about that PCP&C PSU there.... it's RED ! That's obviously not meant for an nVidia card.

That's true.

But if these really are the requirements, then that's crazy.

I think the 48xx are gonna be selling like crazy in comparison.

It is crazy,thats the point!

Reply to Milos-stancene

Think that this gpu pulls 200 watts, or about 17amps, thats steady in 3D. Youll want another 15 amps for your system, so a 35amps psu should work for total 12v rails. And thats a good psu, no room for cheapies here

Looks kinda fake.
But if it is true, I'm not buying a card that needs a PSU bigger than 500 w period.

Maybe it's ATI time for me, or discrete graphics maybe

No it wouldn't work... first off you did your math wrong... 3 X 17A 12v rails would put the total at 51 amps.... not 37.... and the GTX 280 needs an 8 pin connector... which you say your PSU doesn't have... so it wouldn't work...

could you make one in photoshop and show me? I'd like to see your complete uberness in photoshop =D

No sir you are doing your math wrong. If you look at it this way.. 12v * 51amps = 612 watts. That is not what my PSU is rated for. Lucky for me, my PSU tells me the total wattage of the 12v rails on the power labels. The total wattage of the 12v rails are 456 watts. Divide that number by 12 and you will get the total amperage, 38amps. I dont feel like scouring through PSU guides but can somebody else get a link to prove my point. btw they make 8pin molex to pci-e. And I have 1337 photoshopz skillz XD

Reply to terror112

At 17 amps per rail, thats max, meaning the most any given rail can produce. That doesnt mean that all 3 rails at the same time can give max. The max nomber is the 38 amps, which is available to the 12v rails, Got it?

Its showing 22 amps per rail, not sure about total amps on the 12v rails. Looks a little on the edge, it MIGHT work, but itll be close. I myself, wouldnt do it. Im thinking something in the 550 to 600 watt range, with at least 24 amps each rail,on a 2 rail 12 volt.

I believe it says 32 amps total for the 12v rails for the 500watt enermax. As for me I might want to upgrade to the 610watt PCP&C unit. 50amps on the 12v rail. Plus the fact that I will probably never get SLI or Xfire. Just that my main game doesnt support either (CSS). But I do still play Oblivion, COH, and COD4 which can make use of it.

+12V1 = 22A
+12V2 = 22A
32A

Reply to Milos-stancene

Oh man, about anything. Best case, the computer keeps rebooting, or doesnt boot, worst case, the psu goes, and takes something or things with it, because of the surge. The psu will keep drawing til it spikes, when it fails, that spike can be bad news

Thermals cause resistance. At peak usage, thermals are high. As the demand goes up on an underpowered psu, itll ask for more and more, and thermals keep rising causing more resistance etc, til something gives

Reply to jaydeejohn

Its like a chain reaction. Exactly what jaydeejohn said. It is always nice to have a powerful powersupply, just so you dont have to buy a new one every time a new video card comes out. Although if your rig uses much less energy than the powersupply is rated for, you will heavily lose efficientcy. So it is always nice to find the balance. IMO I would say that choosing the Psu is the hardest decision you will have to make when you build a new rig.

If anyone would like to compare to mine. I have an Antec NeoHE 550w, which has 40a on the +12v rails, and I am getting the PP&C 750w in order to run this card. But I have 4 hard drives, an OC'ed CPU, which is about to go about 400mhz faster in the next few weeks. 4gb of ram and other peripherals not worth mentioning. I do not trust my 3 year old 550w NeoHE to get the job done.

Now take this for what you will. If it were new and I were running only 2 hard drives with a mild or no OC. Then I think it would do the job just fine. So if you are one that is in the former...like myself, and want this card I would recommend upgrading. If you are the ladder then you will probably be ok.

Best,

i bring you nub to this link http://extreme.outervision.com/psucalculatorlite.jsp for all of your psu/watt/amp calculating needs. This calculator seems to overestimate by ~2-6% in 3 of 4 of my machine specs, or theres something wrong with mah own calculator orz. GTX280 isnt listed as an available option for lite yet, but add 280w's to the calculation input, leaving videocard 'empty.' Yes, the GTX280 will draw ~280w MAX under full stress. While playing max options on CoD4(and running torrentsorz), in the middle of a huge fire fight and airstike is happening in mah face the system was recorded to be drawing a peak of 530w's.

Im getting the new Intel i7 CPU along with the Asus P6T Motherboard and a GeForce GTX 280 graphics card.

I need help finding a power supply that can handle this. My main concern is the GTX 280. On the box it says it needs at least a power supply with 550 watts and a 40amp on the +12v rail.

Should I get a multi-rail or single rail? Modular or non-modular? I have heard all the debate between these differences but still not to sure.

Any help would be appreciated.

I wouldnt go for anything less than CORSAIR HX1000 - advantages : not very expensive, high quality with solid capacitors inside, modular, 83-86% efficiency, pretty quiet, not running very hot even at high load and the MOST IMPORTANT THING: due to high quality components used is NOT SQUEALING under heavy load like 80% of the existing PSU's are !
