looking to crossfire 7970's, need new motherboard,psu and case..

post #1 of 9
Thread Starter 
Got a bit of a issue. Currently i have a z68 pro3 gen3 motherboard with a 3570k and a 7970 with a corsair gs 600w psu, my motherboard doesn't support crossfire, neither does my psu or aerocool case.

In fact my aerocool case couldn't even fit 1 7970 in it as i had to use pliers on the hdd bay to squeeze the 7970 in. For the record the 7970 is a HiS model and is a bit larger than the reference model i think @ 30cm, or 11.8".

So i have $500 with which i am looking to upgrade the case, the psu and the motherboard. I need a case that will fit these huge 7970's, i dont mind if it's via removable hdd bays or not. Most cases i have been looking at are around 12" and i assume that's for 1 slot not 2.

The motherboard needs to be able to do crossfire properly as i have read that some support it but dont do full speed on the second slot. And the psu obviously needs to be able to run this thing. So far this is what i am looking at, any suggestions are more than welcome...


PSU:

Corsair TX850 $165 or Corsair HX750 $198



Motherboard:

Asrock z77 extreme4 $135 or Asus P8z77 V-LE-PLUS $159



Case:

Corsair cc600T white $185 or Antec 300 Hundred 2 $77 or coolermaster HAF 932 $161


Anyone with better/ cheaper/superior ideas or that can see issues with what i have selected please post as this will be my first system build. Cheers!

The above Corsair PSUs are overpriced for what they are. Since I don't know where you live, I'll use newegg:
- Capstone 750M
- Aurum 700
- Silencer Mk III 750W

All are from this list:
http://www.overclock.net/t/183810/faq-recommended-power-supplies.

Extreme4 is good value (forget the LE) but you can also get the UD3H for around the same price:
Gigabyte Z77X-UD3H.

Case: Rosewill Thor V2 is also good value (you can get it in white).

I'm in australia, this is basically my selection for psu, case and motherboard.. http://www.msy.com.au/Parts/PARTS.pdf

That gigabyte is about $40 more, is it better? If it is i would gladly get it, but if it's basically the same then obviously i would save the money and put it towards the case or psu.

From the PSU list, the TT ToughPower XT 775 & Corsair GS800 are best values.
Extreme4 is a good budget board (I have one) with one of the fastest boot times I've ever seen. UD3H has better components (Phases, VRMs, MOSFETs....etc).
CoolerMaster 922XM is a solid case & good value that will fit any card:

I dont know that the 775w would be enough would it? I think im gonna go with the asrock extreme 4 , i know my way a little bit around the z68 pro3 gen3 and this is my first build so it might help a little, If their isn't a reason to change to asus or gigabyte then i wont. Liking the look of the antec p280 case aswell. Bout to check out some reviews of the coolermaster 922xm aswell, couldn't find many good youtube videos of it.

3570K consumes 77w (around 120w oc'ed)
7970 consumes around 240w + 240w for another 7970
50w for other components.
If the CPU + GPUs are under 100% load @ the same time (which is very rare unless folding), total power draw would be less than 650w.

Mine is the Haf-X (side 20cm fan) which cost more thus not a great value.
Good luck with your purchase(s) mate & enjoy your 7970s thumb.gif
