Can my Powersupply run an R9 295x2?

[jaypremier]

EVGA SuperNova Nex 750b is my powersupply and I was curios if it could run an R9 295x2 without any problems?

Theoretically yes, since the card pushes 500w alone.

Linus explains here about what you need to do to power that sucker.

Terve!

That depends a little on the rest of the system.

In theory its no problem, since the card only uses about 500W.

But I assume that you want to run a CPU, MB, some RAM and HDDs with it.

Please let me know:

-what the rest of your system is and

-why you want to use a 295x2 over a CFX config

Sayonara!

It's says a 1000minimum on a 295x2

You have mada a very good point there.

With what I read from there you cannot run the card, because Linus said you need 28 amps at least.

The PSU does only 20 amps though. But you can still go crossfire with two 290x graphics cards, which I recommand anyway.

You have two cards, so you can use one on an other system if you needed to.

Also you can RMA them seperately (huge deal for me, having dead stuff all the time).

And I think that it just looks so good, having the two cards over each other.

the card only uses about 500W.

 

I remember the days when we talked about cards that only used 75 watts so they didn't need external power, only took up one slot, and only had one fan.

now they only take up two slots, only have two power connectors, and only draw 500 watts. nbd

leave it up to AMD to solve any problem with brute force instead of proper innovation.

hard to argue with the performance for the money though.

I have a 4790k running at stock, 4 case fans, 16 gbs of ram, 1 HDD and an SSD.

And the reason i want it over cfx if because it is cheaper and it will run cooler.

I'm not a huge fan of these specs.

I ran a 7970 crossfire setup with an i7 and all that off a 650W PSU.

Yes, the min power recommandation for a 7970 was 500W (if I recall correct though), but I am shure that it rises with an other one of them.

Also a 295x2 is not that different from a 7970 cfx setup.

[jaypremier]

so i cant run it then?

As said above, you don't have enough power on your rails of your PSU.

Two 290x will run, if you hook them up correctly. But not the 295x2.

Also a 295x2 runs at about 70°C no matter the liquid cooling and a non reference cooler on the 290x does well (not shure about exact temps).

For the cost:

vs.

You get pretty much the same price.

Where woud you buy the cards that it makes such a difference?

well the 295x2 was $550 and it would have been easier than messing with cfx in my opinion  but i guess i will just wait for a price drop and on 290x's hopefully when the 300 series comes out and pick them up then. thanks for helping

Well the R9-295X2 IS literally two R9-290X in Crossfire...but on one board.

I don't quite see how two separate R9-290X's have much more hassle; I mean, you no longer need a Crossfire bridge, and you still need a similar PSU with the amount of power output.

Well there's that:

Guess you won't have that with a single card.

And the problem with his PSU is not that it does not have enough power. It's just that the rails itsself don't deliver the needed power.

I'm sure you can run that card off of a 850watt PSU just don't do any major overclocking and you should be fine. But 1000watt if you are paranoid

Are we talking about the same nvidia? You know, the company that made the FX Ultra AGP 8x hairdriers and until just recently with the Maxwell architecture wasn't all the power conscious?
