My system, that u will be buying soon

Well, nvidia says for one min 600w, so just add the tdp of the other and its around 850w, that way you'll have a bit of head room, depending if you have a haswell or not.

I would recommend a 850W PSU just so you can overclock them really high as well as your CPU and you wont have to worry about maxing out your PSU.

[GrievingJosh]

I would say about a 800-900W PSU, because I think it won't be overkill but will still be sufficient, assuming you want to overclock them.

[TygerStrype]

I wouldn't get anything less than an 850 watt powersupply, better safe than sorry.

750w it's sweet spot for you

[TTesla]

Ohh, and for your system get a hx series power supply. Your current is to overpriced, and for what? Better 80 plus?

Also change your ram to vengeance low profile (low profile with compatibility) . The extra clock speed of your current will result in VERY small extra overall performance. Also try a better case, this has quite of few downsides. Check out

Also the 4770k offers little to no extra gaming performance over the 4670k. Your motherboard is overkill. Unless you REALLY want the amazing sound on it.

750w it's sweet spot for you

Hmmmm. That's a bit low? Add 100w and THAT's the sweetspot allowing for lots of overclocking

760i should cut it but with the current price rise on parts in Australia since the dollar dropped back I would say there is way too much money being spent on that rig on irrelevant things. 260 bucks for a psu is criminal when http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=15350

Would do the same job for less.

[WoodenMarker]

A 750-850w bronze would be plenty.

As for the ax760i, it's a bit on the overkill side. 

 

Why a WD green and black though? Just get 2 seagate barracudas in raid 0 for much better performance.

Have you looked into the G45 Gaming mobo instead?

[CoolBeans]

750 but if you want more headroom you should get 850

[tedjani]

Hmmmm. That's a bit low? Add 100w and THAT's the sweetspot allowing for lots of overclocking

the system needs 737w of power so yeah you are right but not 100w 800W psu is good for the job
