PSU requirements for 2 x GTX660's

[CraigRobbo]

As per title, I currently have a corsair 620W HX.

I would presume this wouldn't be enough?

I have i7 3770k OC to 4.2ghz and 16gb ram.

Thanks

I would only use a minimum of 700W for that system.

 

[BriT]

A good 750watt should do.

 

[CraigRobbo]

Thanks for that guys!

any specific recommendations?

YOUR BASKET
1 x Akasa Venom 750w Modular '80 Plus' Power Supply £79.98
Total : £89.88 (includes shipping : £8.25).



These get a good rating and a good write up. I am poor with PSU's though, so I would rather someone else gave a recommendation sorry.

The HX will be fine for two 660s.
They use next to no power, something like 130w tops (each)

I tried a Antec 650w with two 660's and although it worked it sounded like it was under a lot of stress. I have replaced it with a XFX 750w.

 

[CraigRobbo]

Thanks guys, I will look to upgrading

I don't think you need to replace your PSU.

your pc with 2 660 should use around 500W.

This, no point upgrading unless you really want to get yourself a newer model or have disposable income.

Should be fine, upgrade if it's an old psu I suppose.

If you are going to upgrade a PSU now or soonish make sure you get one that is fully compatible with the new Haswell ultra low power state requirements, it would be silly not too.

Please see our link to suggested PSU needed for GTX660 SLI.

Our 650W Gold PSU would work fine for this set up.

Already tested and approved to be working for Haswell.

Snap! Although I was using 2x 670's. Bagged the XFX 750 silver that was on offer on ocuk recently.

Out of interest which antec 650 was yours? Mine was the TP trio (about 6 years old I think).

It was the 650w new Truepower, the first one went up in smoke after 3 months and the replacement makes such a noise that it is unbearable when running SLI. I can't be bothered to RMA so I have put it down to experience and won't buy Antec again.

Its more than enough mate, absolutely plenty. My overclocked 680 and 3570k barrly draws 400w from the wall so your sli 660 will draw slightly above it around the 500w mark. No point upgrading, put the money towards an ssd or something else.

I would keep the 620 HX, here is a review where it was operated at 750W @ 48C ambient and handled it very well (900w from the wall socket )

I would say this power supply will have no problems running right up to it's maximum spec, which is more than enough for 660SLI
