Basic Guide Purchase a New System

@Tenida, XFX 650W pro edition is enough for 6950 crossfire... If constantine has extra dough to spend, he can get TX750 V2...

 

[Tenida]

^^ok

 

[constantine]

Check Asus P8Z68-V


Quality wise GS700 < TX650 V2
If i were u, i'd get XFX 650w pro edition w/o any hesi..

Come on man ! the only difference is a SATA 6gbps port on the side. And the price difference is about 1k !

Seriously though why not the cheaper but similar MSI or Gigabyte models ? Cause i wanna save some money and go for the Tx750 v2 or XFX Pro 650w .

Also arent XFX Pro is the same as XFX Core , sure its enough for a xfire ?

Pro series is the core series...
Damn sure XFX Pro 650w for 6950 CF..
So far only ASUS has better Z68 mobos in India..

Gurur3d says 650w for basic system, for high end systems like 2600ks get a 800w unit: Radeon HD 6950 CrossfireX review

While it might be overkill I do suggest 750w units, psu's have greatest efficiency at half loads, at higher loads it drops. So overall power consumption from wall will be lower for 750w units.

I run my XfireX on 650W. What more..?

 

[nilgtx260]

^^ we got the answer, nothing more

Asingh is running 4890 CF on TX650W + OCed Q9550 @3.85GHz...

AFAIK 6950 consumes less pow than 4890

That's amazing!!! Putting asingh's config in eXtreme Power Supply Calculator, I get a minimum power requirement of 863W and recommended PSU of 913W!!!

I guess we are bit paranoid about our SMPS. A quality PSU can really handle much more than what it is rated for.

Corsair FTW!!!

 

[nilgtx260]

ya thats what I said regarding HX 650w

How you got such high ratings..?

 

[Skud]

Whatever system config you have given in your siggy, i just put them, including OC, CFX, fan controller and fans etc. And got that result.

 

[asingh]

I got like 638W.

 

[Skud]

Emm... have you OCed your CPU? And I choose high-end mobo and keep capacitor aging at 50%.

 

[Cilus]

Corsair TX750 V2 is excellent psu for your needs.Its price at Rs 6.7k+vat.Don't know about other solution.
@Cilus-Will Corsair GS700 is enough to crossfire HD 6950?

Your PSU is having 56A current on 12V rail as per I remember. So I think it can unless you are on heavy overclocking of every components.

It is just 2 years old.

 

[Skud]

^^ But still I couldn't get it at your level. It's more or less around 800W.

See this specs

Will be Gs700 enough for Intel core i7 2600k,MSI/Gigabyte Z68 mobo ,MSI gtx560Ti TF II OC,8GB ddr31600mhz ram?
