how much power does a 480 need?

[Jericho.u.k]

hi all
i was having a disagreement with someone about how much power a nvidia 480 uses. I think it uses 300 watts at least but the person thinks its a lot less than that. I just didnt want this person to go buy one then find out they needed a new power supply because they think thier 620 watt psu will be enough.

If anyone can help clear this up then thank you in advance

Thanks for the reply m8

i had no idea the 480 used so much.......i knew my 4870x2 used a lot but the 480 uses even more than that and the 5970 too ,im shocked.......as another question does anyone know how much power any of the new 6 series cards use?

thanks again stulid that awnsered everything i needed to know.
Looks like the 6 series are quite low demanding. Now if only the person i was trying to tell would actually listen that i was right about the 480 using a lot of power. But alas they are just one of lifes know-it-alls lol

Running a 480 gtx and done some testing with a plug in power meter.

615w with Prime & Fur Mark running
405w with Prime running
503w with Fur Mark running
272w Idle

615 watts just wow

what psu do u have RJC? because the fella i was trying to tell that a 480 used a lot of watts would never be able to run the prime and furmark tests together as you did with a 620 watt psu lmao

I`d like a card which is very powerfull, quiet ,low wattage at both load and idle and where the temps are low at both idle and load............any ideas if such a card exsists? LOL

i`ve had experience with the 5970 and the only reason that would fail my perfect graphics card test would be the load wattage even though its only 10-20 more than my 4870x2 LOL
