HD 6870 Crossfire and 600watts

[someguy198650]

I already have one Powercolor 6870 and I'm planning to do some Crossfire with another Powercolor/Sapphire 6870, Will my current specs suffice, Isn't this going to "bottleneck" my other hardwares?

Processor: Intel I7 2600 LGA 1155(Lock)
MOBO: Gigabyte Z68MA-D2H-B3
PSU: FSP Everest 600W 80plus
GPU: Powercolor 6870 1gb ddr5
Memory: Kingston 4GB x2
ATX: Corsair Carbide 400R
CPU FAN: Thermaltake FRIO OCK

Thanks

This is your PSU, right? Well, it only has 1x6pin and 1x6+2 pin.

So if you want to CF 2xHD6870 then you must use 4pin to 6pin adapter, which is not recommended...

the rest of your specs are good, I think you should get a better PSU, Antec, Corsair, OCZ, SilverStone are one of the best out there...

Thanks for your reply, so I guess my current PSU wouldn't work for CF ?

I think you'll be more "safe" with higher(better) PSU.
Take a look at this:

I have a new Corsair Enthusiast Series TX750 V2. I am getting another XFX HD 6870 Black Edition and CrossfireX them with that PSU. You should pick up a better power supply. My PSU is also 80 Plus Bronze Certified.

I think I'm going to get Corsair GS800 800W in the near future

Sure, that's a good PSU, nice choice...

You don't need it you can get basically the same one I have and you'll be fine dude and save money, its a 80 plus bronze 750 watt man, you don't need more for SLI 6870s.

 

[someguy198650]

Btw, I'm also considering this one - FSP 800watts Everest series 85PLUS 800, cheaper too

This one?

Nah, do not cheap out on PSU, It's the most important thing inside your PC. Besides, it only has 2x 6+2pin power connector for PCIE card, Corsair is MUCH better than that FPS PSU...

 

[someguy198650]

Thanks again for the reply, how about this one: Antec 750watts True Power ?

Yes, that's a good PSU, if the Antec750 is cheaper than Corsair800 then absolutely get that Antec...

 

[someguy198650]

Thanks, Antec 750watts True Power it is !!

 

[mf2385]

I bought the Corsair TX750W v2 80+ BRONZE. Anyway I am going to buy another HD 6870 Black Edition and CrossfireX.
