the problem is not whether these cards will fit in the mobo but the power supply . For R9 280X you ll need 2 x 8 pins pwer connectors and extra 300W .With this psu no .R9 270X needs 2 x 6 pin power connectors and 225W .R9 270 needs only one 6 pin connector ,more likely to have it , and 175W .it is only 5% slower than R9 270X.

99% R9 270 will work , check if the psu has one 6 pin connector

for R9 270 , check whether your psu has two 6 pin power connectors , it it has , 99% probability
to be 100% sure , see how much Amp has the psu on +12V rail .

1) yes, there is a free 6 pin connector
2) +12V A -- 18A
+12VC -- 8A
+12VB -- 16A

16 A x +12V = 216 W < 175 W , so R9 270 will work

thanks, so if i want a 270x or 280x card i must change mi psu... do you think http://www.amazon.com/Corsair-Builder-Series-Watt-CX600... its a good option?


it has 2 x 6 +2 pin connectors and enough 46A on +12V rail , so it can power R9 280X
the spcs file here

R9 270x is only 5% faster than R9 270 , just a bit overclocked version . it is not worth the extra money .
