@IcY18:
Think 600W will do it? Kinda worried when you're looking at C2Q sucking up almost 200W, five big HDs, and these estimates being tossed around of some cards soaking up 250W! Maybe that new Intel PSU 90% efficiency on one rail might do the job!
@Doughbuy:
If I had $15 billion, I'd buy a South Pacific island and stock it with hot and cold running blondes. Let's put a Money Is No Object As Long As It's Not Over A Grand addendum on this!
CPUs are not sucking up almost 200W, most people out there will never use their CPU at maximun load unless they are stress testing or benchmarking there and with the new Core 2 Quad rated at 125W i don't see any CPUs nearing the 200W mark since Intel's new goal is all about price per watt, and the only reason the Core 2 Quad is has that high of a rating is because its 2, mind you
2 Core 2 Duos, the fact that they kept the rating that low is great in itself, don't expect cpu wattage ratings to go any higher than 150W in the near future
expect new native quad cores to suck even less wattage, the cpu wattage requirement should not ever worry you unless you plan on overclocking,
five big HDs...i don't think so, with Seagate and Western Digital pushing the limits of gb/platter you'll be seeing 1.5TB harddrives soon enough, we already have a 750GB HD, and that along with flash memory in combination with regular harddrives to make a hybrid drive would allow the hd to consume even less power.
what people lack to understand is that a cpu and gpu and hds will never run at full maximun load all at the same time for even a short time, and ratings by nvidia and ATi are on the safe side to prevent the community to go up in arms because they said you need a 27A psu, when you really needed a 30A+, with the pc usually never at full load even if your psu is rated at 600W and somehow you manage to get your wattage rating
no one really knows how much wattage their computer actually draws?
how much would a a power hungry (just as power hungry as the C2Q)FX-60, 2*7900GTXs, draw at full maximun load? 500W? 450W?
a measly 371W, bump that up some for the X1900XTXs, to say about 410W(overestimating) then say dx10 takes the an overestimated big leap of 150W, (thats 75W extra watts per card) and that puts you at 560W, even then after over estimating your still under 600W, granted this is when the gfx card are at full load
so in the end i think a 600W psu will be fine, but if you wanted to be on the safe side a OCZ GamerXtreme 750W would be overkill , but if you want to be safe there you go, anyone with a 1KW PSU has gone way over the top and then some...
