Good PSU for GTX 670 SLI?

MysteryINC · Aug 27, 2013

Hi there,

So short and simple, what is a good PSU for a GTX 670 SLI?

edogawa · Aug 27, 2013

Many are, but a fairly well priced quality unit is the SS-650KM.

Any UK sites?

Man its SLI, too weak for everything, you can have some problems with 650...
You definetely need at least 700 W. http://www.newegg.com/Product/Product.aspx?Item=N82E16817103080 This is great one.
Are you going to overclock?

Honestly don't know about stores outsides the UK that are good, so someone else may need to help you on that.

Most Corsair or Seasonic power supplies are a safe bet. A good 600 watt power supply from either of the previously mentioned brands will support SLI 670's.

For a 760, I recommend the XFX Core 650W or if on a budget, the Corsair CX 600. Both are high quality units at good prices.

MysteryINC · Aug 27, 2013

Is a Corsair CX750M Modular CP-9020059-EU good?

edogawa · Aug 27, 2013

It's budget, which means low quality.

It will work fine for SLI, but if you plan on doing any overclocking, or run your PC a lot I'd stay step it up a bit to a higher quality unit.

MysteryINC · Aug 27, 2013

I'm just stuck, I'm thinking about SLI'ing 670 or just one 770 which is easier to go with? And will the Corsair be enough to take one 770 with no further problems?

Edit: Is this better: http://www.scan.co.uk/products/750w-seasonic-m1211-750w-hybrid-modular-80plus-bronze-120mm-silent-fan-sli-xfire-atx12v-eps12v-psu ????

The 770 is just an overclocked 680, and the 680 isn't much better than a 670. Go with whatever is cheaper. You will be fine with either SLI 670 or SLI 770 power wise. A single card fast card is always good to go with, a single 780 might be a good option too to avoid SLI issues, but the SLI 670's would be much more powerful. Most new games shouldn't have many issues with SLI too.

MysteryINC · Aug 27, 2013

Well, I have a promotion that 2x 670 is only £300 and a single 770 a £274...

edogawa · Aug 27, 2013

MysteryINC :

Oh, that's a killer deal! That's a free 670 with the purchase of another. I would definitely go with the dual 670's in this case as even a single card can run almost all current games maxed out above 60FPS great.

What kind of promotion is this anyway?

MysteryINC · Aug 27, 2013

It's one of those "Scan One Day Deals"

But then I have to invest in a better PSU

Which I know sounds stupid but I'm really not that able with investing a lot of money into a rig right now but I really need it..

edogawa · Aug 27, 2013

If you need something, you need it, but that is one hell of a good deal. You could even sell the second graphics card for a profit after the promotion is over.

Anything Seasonic 600-wattish should be fine, or a Corsair CX/TX wise.

MysteryINC · Aug 27, 2013

Well, anyway thanks for your help

I'll probably go with a 670 SLI and a Seasonic PSU

No problem. Enjoy!
