DX10 cards power draw? what u think

[jaws104]

I've heard the new cards are going to draw heavily (r600 especially)

Recently got an enermax liberty 620w, u think it would be enough for O'clocked single card system??? (intel E6600)

Hi Jaws,

I recently brought a Seasonic 600 S12 watt from overclockers, and at this time, was searching overclockers forums for other people using this psu. Someone does crossfire (X900XT) on this psu>>>> http://forums.overclockers.co.uk/showthread.php?t=17532530&page=2&pp=30 <<<<< ("Raja" poster #36) (18 amp x 2) so would have though 620 to be sufficient - who knows though

What amps do you have on your rails(s) if 2 rails (like mine) what is the total?.

Me and Raja both used the Seasonic S12, but unfortunately it didnt hold up in Crossfire.

Raja ended up with the Tagan 900W and i opted for the Sparkle 700w

Im sure it will handle the single cards fine though

 

[Slam62]

how ridiculous, presumably at sometime there'll be lower power version for most people to use.

 

[Cyber-Mav]

without any real cards out on the market it can;t comment on their power consumption.

Just looked at my crystal ball, but its to foggy to see owt, so i can't say how much power they'll use.

 

[HicRic]

If I were to take an educated guess, I'd imagine we'd see a continuation of the current trends. The high-end cards will continue to draw a fair amount of power (think X1900XT?) whereas the slower, more middle/low end dx10 cards will draw less.

Having DX10 support won't intrinsically increase power requirements, so just expect business as usual really. I'm sure if you stick to a single card the enermax liberty 620w will be fine.

Not 100% on this but i see 22Amps on each 12vrail = 432W total?

I would'nt, x1950 is due, and thats an 80nm process, and so draws less power.

 

[Jokester]

Rumour I've heard is that R600 will use less power than R580 (or whatever the current one is).

Nvidia wise not sure, they're not so bad at the moment anyway.

[iraiguana]

just read over the inquirer that its possible the power draw for the g80 will be in the region of 180-200W :S so who knows what u will need.

 

[jaws104]

Today's inquirer -

"The short story is this, G80 form Nvidia is looking to suck down 175W on a 90nm process, probably a bit less on 80nm. R600 from ATI is looking to take about 200W in 80nm, and less if they pull off a shrink to 65nm."

EDIT /\ beat me to it

 

[Jokester]

If that's true, my PSU won't cope.

They're making PSUs just for graphics cards. They were demoed at CES.

Fortunately AMD and NV are pulling back after the next gen (X1950 is current gen for all intents and purposes), reducing power consumption. Or so rumour has it.

 

[Cyber-Mav]

i doubt there will be much of an increase in power consumption. the way things go with technology it just gets smaller, faster, less hotter and eats up less power.

new gpus will have an efficiency increase and also and gddr4 is also less power hungry.

 

[Jokester]

Actually, new hardware generally uses more and more power, particularly when it comes to CPUs and GPUs.

I refuse to buy a new card that consumes more power than my x1900. My guess is that cards with a unified shader architecture will be more efficient than those currently. Hopefully, this combined with manufacturing process improvements will mean that a PSU upgrade isn't needed every time a new generation of graphics cards comes out.
