r9 280x and r9 280 crossfire !!

[cruch3rx1]

Can i crossfire r9 280x with r9 280 ?!

sorry for bad english 😀

 

[Eduello]

Yes, but it's going to be limited to the speeds of the non-X version.

This says NO.

Crossfiring a 7950 and a 7970 is possible, and those cards are essentially the same as the 280 and 280X...

Yes, but it's going to be limited to the speeds of the non-X version.

very happy to hear this , but there is a little problem
I have a cooler master silent pro m2 720w , is it enough for the 2 cards !?

 

[Eduello]

Probably not, I'd recommend at least 850W. Also, it would be best to have 2 identical cards, otherwise you're not getting all of the performance of your cards.

I thought that is true :| you saved me 😀 , so why the two cards only takes 562w Entire system ? and he Said " our test system is bare minimum - only a SSD hard drive is used with a single CD ROM and minimal cooling fans."
and here http://www.ocaholic.ch/modules/smartsection/item.php?page=14&itemid=1335
626w only entire system too .. Can you explain to me ? , I know that I disturbed you, but I need your help

The GPU benchmarks don't really put load on the CPU, so games will cause the power consumption to go a bit higher. The PSU you have is not very high quality, so I wouldn't put it under high loads.

The last question 😀 .. what about 270x toxic crossfire ? is it enough 650w ?

 

[Eduello]

Should be enough for that, although it's a bit borderline.

this would it be good ? it's for another pc.

 

[Eduello]

It's not that great, I'd recommend anything from XFX, Seasonic, or Corsair (AX, TX, and HX untis only).

i got your point , if the 270x CF with my psu Cm silent pro m2 720w , should be fine ?

 

[Eduello]

Yes, it should be enough.
