How many Amps does a OC 6970 use, and how many is expected on a voltage OC

post #1 of 19
Thread Starter 
So how many Amps does a OCed 6970 draw off the 12V p6 and off the 12V p8 cables


I cheaped out on the size of my PSU when I bought it late Nov., and I changed back to wanting to CF, and now the 69xx s out.

I think I'm going to get a XSPC Rasa 750 RX360 for the CPU and CF 2 69xx with the full waterblocks....so I can potentially OC them quite well.

But anyway for now my Seasonic M12ii 520W should do for 1 card.

But later when I get the other 69xx, I would like to use a spare generic 500W PSU for the 2 needed PCIe, (I would green+gray daisy chain the PSUs so they turn on/off together)

It might not be safe to use a generic PSU like that. Why not just replace the M12II with a quality 650W? That's all you'd need, really. Or, maybe a quality 700W.

well your first two problems with that PSU are that it has 2 rails instead of one, and it isn't high enough wattage, I would suggest a higher quality 650watt, 700watt at most.

Look into corsair, they normally will go on sale on newegg alot.
another good brand is PC power and cooling.

Antec has some good PSU's for the price but just make sure you get a good one, ask around before committing to an antec.

Unfortunately PC Power & Cooling is not as good as they used to be:

So, Antec's 650W TruePower New is one of a few very good low-price options.

well that sucks. I remember when OCZ was amazing stuff, now people just look at them as kinda half assed.

I am very glad I bought a TX650 when i did. I got it on newegg for 75 dollars with a 25 MIR. So for 50 dollars I got an extremely good PSU.

No, well, yes, I remember when PC P&C and OCZ were both considered amazing products, Memory for OCZ mainly. But then OCZ fell of the board for memory and now PC P&C are gone, we have corsair for PSU's now i guess.

What i find funny is kingston hasn't lost their foothold in the market after so many years.

I don't remember a time when OCZ was considered a great choice for power supplies, but that doesn't mean much.

Anyway, today we have Antec's TruePower New series, XFX's Black Editions and XXX series (and I guess even their Core series or something), SeaSonic's S12II's, M12II's, Rosewill's Green Series, Silverstone's Element series (I think), Antec's ECO series, Antec's High-Current Gamer series, and a few others.

I was trying to avoid Corsair because even though their HX and AX series are hot, I am almost growing tired of seeing people think that every single Corsair PSU is the best of the best. So, I don't want to encourage it.

I ment OCZ for memory, and various other accessories. But I just got the TX650 which is a very nice supply even if it isn't up with the super high end ones, and you can't argue with 55 dollars for a supply of this quality.

I suppose. But I have a couple of contenders that are supposed to be superior:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182191

Both of these are the Rosewill Green series. smile.gif
