is a corsair hx750w good with xfx r9 270 crossfire (non x)

the heading is self explanitory and the ggpus are non x and 6 pin both

Yes it should be more than enough. HX is very high quality, you could probably do it with 650W too but 750W is more than enough headroom for overclocking as well.

thankyou, crossfire is laggy for me which is why i ask, i run bf4 ultra 720p at 80fps but in sli 50-60fps

There's many problems with Battlefield 4 but you should be able to run it at 1080p too with 60fps if you drop MSAA down to 2x. My 270X gets 60fps ultra settings 1080p (2xMSAA) with rare drops to 30 when something crazy happens so 2x R9 270s will handle it better.

Make sure resolution scale is set to 100%, nothing more as you'll require a very powerful PC for higher than 100%.

Does GPU-Z recognize the two GPUs working in Xfire? Battlefield 4 should scale well with dual GPUs. Is your system Windows 7 or 8? Battlefield 4 is optimized for Windows 8.1.

yes it is recognized and im running windows 7 64bit

The performance benefits from running Windows 8 can be very significant when running Battlefield 4 so maybe that's your issue. Apart from that I can't think of anything that would be of issue, though there was a recent update which resulted in massively reduced performance but I think DICE patched the update by now.
