Here's my system which I'll be building soon:

3570k oc @ 4.5
cm hyper evo 212
asrock z77 extreme4/ msi z77a-g45/ gigabyte z77x-d3h
8 gb ddr3 1600
corsair 60gb ssd
seagate 1tb 7200rpm
cm haf 922 case
sapphire 7950 x2 (crossfire)

I was thinking about the power supply and have read in various threads and the Guru3d review that 750watt is enough for 7950 crossfire.

Here are my options: http://www.canadacomputers.com/index.php?cPath=33_443&bsort=0&brand=0&price=1&location=0&&page=2

Here is my GPU: http://www.newegg.ca/Product/Product.aspx?Item=N82E16814202006

I like canada computers because the store is close by and there will be no shipping, but I am also okay with NCIX/newegg canada.

Can you guys recommend me a PSU for this config? I was thinking corsair 750m or the PC & power cooling 750w - I can wait a few weeks to get them on sale.

Thanks!

7950 Cf needs ~360 W on peak so you are reall good. Maybe drop down to XFX 650W Pro Core. Or if you have that PSU its just great

I have decided on the corsair tx750m, which is on sale for $99 locally. I figure it will be a good PSU to use even for future builds and it's also semi-modular. Ideas guys?

well if you decided upon it, then go for it; it is a fine PSU.

BUT is it the older 750m that is 80 bronze rated or the new non 80+ certified?

from the choices before . . .
Seasonic X-660 Fully Modular 80PLUS Gold $149.99

yes its pricey but damn well worth it!

and it will handle a 7950 Xfire set up . .with overclocking.

Thanks for the quick reply! I actually looked into it, and I guess I spoke too soon lol. The tx750 v2 seems to be made by Seasonic, while the first generation and the modular versions are not. Plus they can go on sale to as low a price as $75, which I think is a good deal.

The Seasonic that you pointed out is just too expensive for me, if the price drops in the next few weeks I might consider it.

I want decent overclocks on the 2 GPU, but I will be OCing the CPU to about 4.5ghz, with the hyper evo. The tx750 v2 should handle that, right?

A side question, what do you think of my build? I want to run games like black ops 2, bf3, dota 2, heroes of newerth and that's about it.

Thank you for taking the time.

no problem. glad you did catch that PSU difference a 750 is be plenty for ANY crossfire/SLI configuration - well except the 7970 matrix, power hogs!

as far as your build . . ok you asked :lol: 

i really wonder about spending $600+ on a Xfire configuration but get a dinky 60gb SSD. prices have dropped considerably - at least here in the states. so really my thought is get a 120+gb or just skip it for now. esp with having to micro manage it . . . :p 

but hey the rest is fine, anyone can give a preference for a motherboard . .i don't have one.

Hehe, the thing is I don't download much, nor do I run many bulky apps/games; as a matter of fact my current PC (which I use heavily daily) has a 250gb hd and I am only using 100gb (2gb apps and 98gb of junk)...lol.

I got my 60 gb corsair force 3 from newegg.ca on sale @ $75 - there were cheaper ssds but I chose this primarily because I know corsair to be a decent brand and the reviews (http://www.newegg.ca/Product/Product.aspx?Item=N82E16820233223)

Most of the other SSDs that were priced in the $100 range had many reviews of dying out within a year - I am an ssd newb and I primarily chose it to run my OS and few games off it, I hope it doesn't fail me lol.

Can you give me a link to a good site which explains this ssd "micro-managing"?

Really appreciate it.

Really appreciate it.

some of the micro managing is having to change default locations for user files and programs. like explained in these articles:
How to Change the Default Location of User Folders in Windows 7 and Windows 8
Change Default Installation Directory In Windows 7 For SSD

there are a bunch of references, guides and tips in theis post:
Useful SSD Articles - Part 2
though it is a little dated by now.

with a larger SSD you don't need to worry about that. btw, you ought to keep the used volume under 80% of the space for you have room for the garbage collecting. after you install windows that will leave you close to nothing.

or if you care not to do a bunch of tweeting, you can always install on the hard drive and use the intel's smart response technology and have the SSD as a big cache drive that will speed up your boot time and most used apps.
