You should be ok - what is the system spec?

Where did my reply go? :confused:

Is this a single card. If so then yes with loads to spare. You can run just about any single gpu pc comfortably off even a 550w psu.

It turned into my reply

Not sure, it might of been forum blip.

Not for crossfire unfortunately, which is ashame as it's a decent PSU you have. I'd be looking at a 850w PSU minimum.

i54970k - oc to 4ghz (haven't increased voltage yet)
maximus hero IV
H100i
8gb 1660 ram
samsung 840 pro 128
1 tb WD black
CD/RW drive

And I know im going to get a lot of flac for this but the keyboard mouse and headset I have are all Razer products.

I done a wattage calculator and it said I should have about 80-watts spare. Is that too close for comfort?

thanks

With overclocking yes, you want a bit of headroom.

dinoman88 · 6 Jul 2015 at 14:33

Thanks all for your replies.

looks like im getting a new PSU as well. Any suggestions would be greatly appreciated.

thanks

edit: bad grammar

The XFX and the Antec are made by Seasonic.

Some are semi modular while others are fully modular and gold or bronze rated.

850W is what I use to recommend in the past for a pair of 290s in Crossfire with that sort of CPU and overclock, wattage calculators tend to be a bit "off".

RJC · 6 Jul 2015 at 18:38

Bare in mind wattage calculator give recommended PSU and not actual power draw of the system.

I'm running a pair of XFX DD R9 290X's ( stock ) with a 4690k @ 4.2, on 1.2v, and have seen a peak pull of about 730w, I went with a 1000w just for headroom, and for the whole efficiency curve thing.
