I just bought a 430W antec true power less than one week ago (!!!) and now im hearing that the next gen cards might need a 480W power supply. Will mine be enough or am I going to have to buy another one :(

i think a true 400w will do the job!! :angel2:

However, amongst other things, this picture confirms our earlier story when we got our hands on an NV40 sample at CeBIT.

We exclusively reported here that “the primary shocker was that the board requires two large 4-pin power connectors as opposed to the single power connector on current high-end products”.

We speculated that "perhaps a lot of end-users who have been thinking that they might wait and upgrade to NV40 when it becomes available, should start saving their shekels to upgrade to a new power supply unit (PSU) as well."

Today we can confirm that Nvidia recommends that the PSU for GeForce 6800 Ultra should be no less than a stonking 480W!

And don't be thinking that a PSU bundled with a cheap ass system case or PC typically sold for thirty squid or so will be up for the job

. If Nvidia doesn't produce a detailed list of 'approved' 480W PSU for GeForce 6800 Ultra, then perhaps it should bundle a 480W PSU with each GeForce 6800 Ultra?

No doubt savvy resellers like Dabs or Scan will be rubbing their hands together concocting GeForce 6800 and PSU bundle deals. If GeForce 6800 Ultra ships at say circa £399 ex VAT @ 17.5%, then early adopters who don't have the kind of PSU that Nvidia have in mind, should perhaps budget for another £60 or so. This would mean that the 'solution' price, including UK taxes could be vertical of a whopping £540 (almost a $1000 USD)!

antec 430 is weak.. look at the 12v rail.

We're having topic creep across many threads tonight. ;) Anyway, I'm not sold on the blanket statement that the NV40 will "require" a 480W PSU. I could be wrong (we all could until 4.14.04). For one thing (as Templar points out), the 12v rail is what is most important and varies amongst PSUs. Secondly, PSU wattage is not the end-all-be-all...we all know that PSUs are not created equally. ;)

UPDATE: I can now confirm that NV40s have been successfully tested/benchmarked just fine on 430W PSUs by more than one individual.

Any quality psu with 20A rated output on the +12V rail should do the job.
The Antec 430W psu is not a 'weak' psu by any means and easily powers +12V rail stressed systems that I have seen and used. Its rated output on the +12V is rated at 20A.
I would recommend a number of power supplies, with PC Power&Cooling units probably topping the list, but I would not put aside an Antec 430W TP as an inferior psu for a high performance system.

mm.. i was looking at pricewatch for powersupply and this is
what i found

$43 - 650W
$22 - 600W
$14 - 550W
$13 - 500W
$12 - 480W
$14 - 460W
$9 - 450W
$14 - 430W
$14 - 425W
$10 - 420W
$7 - 400W
$11 - 350W
$11 - 300W
$13 - 250W


not bad.. some of them are so cheap that can be includded for free in cereal boxes.. i think that any 400+ supply should do the Job. but as other have said is more important the quality of the PSU than the numbers.

btw.. i know of people that MOD their Case ,to use 2 powersupplys..
There should be in internet tutorials how to do it.. in that way.. you can use your old PSU together with a new one a save $$ . if you dont want to buy another one. but for someone who have $500 for the NV40 should be better buying a new one.. if money is not a problem.

Just saying a 480W psu is required is a little weak, IMO. The requirement needs to be qualified something like what AMD does by having a recommended listing. Does not really have to go in to that much detail but should identify the important specific requirements the psu needs to meet.

I had a 350W Enermax that actually providied peaked power of 380W while I also had a 420W rated psu that only actually supplied approximately 365W. Stick with quality brand name psu's such as Sparkle, Fortron, Enermax, Antec, PC Power&Cooling just to name a few. My 'guess' would be to look for the +12V output rating. Any of these units with a 20A rating should be sufficient with maybe even less for the PC P&C units due to their high quality components and reputation for supplying quality units.

I've been testing with an Antec True430 and haven't run across any problems so far.

This model has five peripheral power connectors that connect to devices like a HDD or CD/DVD. Two of the power supply leads have one connector on each lead. Neither one of them is shared with any other device, which is very important, and are connected directly to the NV40.

A second lead has two connectors, both of which are connected to hard drives.

The dilemma I faced was that the third lead only had one connector and I needed to get power to two DVD's. A power 'Y' splitter cable solved that problem.

The only case fan I have is powered by the motherboard, which is an nForce3 150 running an Athlon 64 3400+. I use the on-board LAN, but have a Sound Blaster Audigy2 ZS add-in sound card.

NVIDIA recommends the Antec True550, Antec True480 or NEO480, or Enermax EG475P-VE SFMA. I went ahead and ordered a True550 from Newegg the other day just in case :)

seems like our own admin of NVnews has a shiny nv40 and a big smile on his face. When will you be allowed to put up a review? april 13 at midnight? as for psu, wow have they gone that much in price? I remember last year a 500w psu was like $100+

Abit overkill to have an 550w PSU!!

Let me see....
I have 3 hard drives, 4 case fans, 1 cd burner, 1 dvd rom, 1 dual cold cathode like kit and I have 1 connection free though it is bridged from the light kit.

Any suggestions on a power supply that is going to let me have 2 free connectors for the NV 40 with all of this?

No big deal, just Y-split as necessary and you should be fine...what kind of PSU do you have?

Getting an Enermax PSU. Ordered it today.

I should be set with this one for a long time to come. I hope...

I honestly do not even know, it was given to me.
I am looking at the box and it is only 400w though which I was lied to about, lol.
STandared low noise / dual fan with two different colored LEDs so I may as well grab a new one also, I will just make sure to pick up some extra Y connectors.

Think you will be happy with that one (mine is much quieter than my 430 and 480W Antecs) and it should easily take care of your power requirements for a long time to come.

I ordered a Thermaltake 420w PurePower PSU last night http://www.newegg.com/app/ViewProductDesc.asp?description=17-153-006&depa=0 . Power should not be an issue since I have my eyes fixed on the x800 pro w/ 12 pixel pipes.

Not a good idea to buy ones of those crap brand power supplys. Any good brand will cost you around $45-$55 bucks at least, and thats the lower end of whats is acceptible. Pretty steep considering the card itself costs $500. I know I'm not paying that much for a card and a PS, I just barely bought a Fortron 350w for $50. Hopefully the R420 isnt as power hungry.
