Until I see otherwise anyways.
Explain to me how its not enough. I'm really curious, because I am planning to go SLI 470's on my wimpy little 650w unit. Apparently I need a 1200w now?

Go do some reading on power draw, and quality PSU's, then come back and argue.

Enlighten me please.

Will you calm down?
Whats with the teenager attitude and rude tone?

This is a thread about helping someone with a purchase, personally I don't mind the shells little instigators like you have, it don't bother me but lets attempt to be polite here ok? Grow up.

How about go mature some?
And comeback and argue?

Why do you think I want to argue?
Is this a competition to you?

Post proof and calm down or for the benefit of us all, be polite.

If you want go for it. Phaedrus recommended against that for me but you do have a different PSU.

Capwn (here on OCN) runs SLI 570's off a TX650. His fan speeds up a little under a full P95 + Furmark load, but otherwise it runs fine. He's recorded 600w power draw from the wall assuming 80% efficient.

So yes, a 450w will EASILY power a single card of any caliber short of MAYBE a 580 and 480.

What attitude and rude tone? Because I said you're ignorant? Do you understand what that word means? Ignorance means that you are not informed, which clearly you don't know PSU's that well...thus you are ignorant.

Exactly. Why would you recommend him to buy a PSU, when his current unit is MORE than sufficient for just about any GPU on the market? It's not like he's going to get into a super power hungry card with a $250-300 budget anyway.

EDIT:
And no I am not arguing, just preventing the spread of uninformed posts. If you want proof, google is your friend. I don't see why I should have to post proof when its common knowledge.

Not to get into another "debate" with you, but you could spare these boards a lot of arguments if you just listened to people instead of pretending to know everything...

Just sayin'.

With a PSU don't you want to have more then enough?
And thats great a super nice 650W PSU can power SLi-GTX 570's.
Quite impressive actually.

Most rigs I see 750W or 800W atleast.

That chart shows TOTAL SYSTEM POWER DRAW FROM THE WALL. In other words, you're still not even looking at the efficiency of the PSU. If the PSU was 80% efficient at that power output, that would be 320 x 0.8 = 256w worth of power draw from the PSU.

So the ENTIRE tested system pulled 256w from the PSU. So a quality 300w unit could power their test system with ease.

I didn't bother responding because pioneer would probably have a better explanation. And like he said read the article cuz that's power from the wall. the only thing is it doesn't factor in CPU load but that won't pull too much at all.

So the ENTIRE tested system pulled 256w from the PSU. So a quality 300w unit could power their test system with ease.
A 560Ti at load uses 358W!
I agree he can run a 560Ti, maybe a 6950...thats about as far as I would go.

He is pushing it, even with a good 450W.
A good 650W is pushing it with 570's.

In both cases its enough but its cutting it close.

Again...that is SYSTEM POWER DRAW FROM THE WALL. Would you like to argue this point further, and continue being wrong? Just read the chart.
