After finding out how much power that goddamn 6800 consumes, i upgraded to an Enermax 550watt psu, costed me 120CAD. I just hope that was justified, i'm HOPING that the 6800 isn't another prescott.

Just wandering how many of us here doesn't have a 480Watt or more psu? I know i had to just upgrade from 460 to 550.

Ive got a 200 watt!!!! An upgrade was due for me anyway...

That'll be enough L1 cache for me too...

If I do decide an upgrade is necessary, I'll definately be upgrading my Enermax 350Watt PSU. I probably will soon anyways.

You guys are all a bunch of suckers.

I have both an Enermax 365 and 465. But I was planning to rebuild anyways. Just surprised that server class PSUs are required. At the time finding the Enermax 465 was a big enough pain. I have found an Enermax 651, but it's $175, so I'll wait 'til I need one and see what features are available from the Enermax, PCPower&Cooling, Fortron. I'm not fond of Antec personally (I remember there being a few issues with the R300 and NV30 at first, and so they simply slip to an A-/B+ for me). There's a new Enermax with a blower fan instead of the typical blade fan, would like to see how that one reviews. Also the smart fan running for a short while after power down is nice.

I wonder what the power differences/requirements will be for the R423 and NV45 especially since the HIS bridge chip consumes extra power (0.2w or 20 w? Will it matter overall?)

The funny thing is that Intel and ATI had said this was going to happen way back when they announced the BTX line specs and form factors. Remember we're likely to need new connectors when those come along too, so make sure you buy a PSU ready for that too, or you will have a further upgrade in your future.

Actually, you don't really know how much an 6800 consumes since it is not launced yet! But even if we believe all the rumours, I seriously doubt that my Antec True430 for example won't be enough for this kind of graphics cards. If they publicly declare a 460W PSU as a minimum requirement, then it is almost safe to assume that that figure is for cheap/generic PSUs. Anyway, only time will tell, but I on the other hand will also wait until the R420 is out. If it consumes less juice than the NV40, then there is no way in hell I am giving my money to Nvidia, even for more performance !!!

That really depends. If nV means a PSU that will deliver CLEAN 480W of power using at least the two rails, that may even discount the best of the 'lesser' PSUs that will deliver clear power around their range.

The thing is that a recommendation like this will always have wiggle room. Someone running a celeron 2ghz with just a hard drive and one optical, with one stick of memory, won't have the same power profile/needs as someone with a raided raptor laden AMD64/P4EE with PCI audio, multiple optical drives, multiple fans, multiple sticks of memory, etc.

There's going to be no way of determining what will and won't work. However if you currently need anywhere near the power of a 400+ quality PSU, then adding the NV40 or R420 will likely push the beyond the limit.

Maybe the answer is to have only one fast hard drive, 2 sticks of memory, and external optical drive, and no fans just showve your PC in the fridge. Then we can keep our 350-400W PSUs!

As I said earlier, only time will tell of course. But I find it kind hard to believe those power requirements published recently because if they are true, then 98% of all users buying the NV40 will need a PSU upgrade as well.

I don't know if it is just me, but there is a point where I draw the line between eye candy and being ripped off! (I know MANY other ways to spend USD$400(NV40)+USD$100(PSU), especially when my R9500 Pro can actually do the same job .. at least for now) Also, don't forget that BTX is just around the corner as well. If during my next upgrade I will also need to upgrade my 550W PSU to a BTX compatible model, then thanks but no thanks !!!

Btw, if I am not wrong here, trying to boot a system with an insufficient PSU can most likely fry your whole system, or at least part of it. If that is correct, then how the hell will we know if we need a PSU upgrade or not?!!!!

yes its very likely to happen



psu doesnt just turn off , as ive haard from a few people before, it undervolts one end and overvolts the other (not 100% sure about the overvolting thing, it probably depends).. which is not a good thing

I spent it because I know the card's gonna drain power with that 16 damn pipelines, maybe my 460 was enough, but i need to overclock.

Think about all those poor OEM PC manufactures, imaging how they're going to cope with it!
I currently have a generic 300W and I don't plan to upgrade it till one day it fries like sh|tz.

Sucks for those manufactures, Hope Enermax and Antec drop the price on their 460-480 range psu.
