Will a R9 270x which a PCI-E 3.0 card apply to a PCI-E 2.0 slot?

So there is this discount in a store of my country that has the R9 270x like 30% off and seems a pretty solid investment the thing is that i don't know whether my mobo (foxcon G31MXP) will support the card . I was planning to do an upgrade on my pc but for the moment that deal seems pretty good... Should I go for it ? And also ATM i have an 430w PSU which i will also change to an Corsair Builder Series CX600 80Plus Bronze. My pc consists of :
PSU: 430W unknown brand
Mobo:Foxconn G31MXP
GPU :Nvidia GeForce 9600GT
CPU:Intel Pentium 2.6 GHz
HDD:1TB + 250GB

In conclusion with the new psu will i be able to cover the aformentioned CPU,the HDDS and the new gpu? Just keep in mind that this will be temporary as i plan on an upgrade i just want to see that if i bought the R9 if it will able to run on my current system . Thanks in advance :D

  1. Best answer
    Yes the CX600 should be able to handle a CPU upgrade too, so you can keep it for when you do that.

    And the R9 270X should work on PCI-E 2.0, most AMD boards (if not all imo) still runs PCI-E 2.0, i myself ran a 7970Ghz/R9 280X in a PCI-E 2.0 slot. :)

    So no worries here ;)
  2. So i will be alright using the R9 on the foxconn? If thats the case then those are great news
  3. Will an r9 270x fit on a Gigabyte 78LMT-USB3? It only has one pci-e x16 slot. It has one pci-e x1 and a pci x1. If so, will a 280x fit?
    Thanks.

    Yes, because the x16 is PCI-E 2, so the motherboard should support any new gpu with PCI-E 2.0 or PCI-E 3.0.
    Both cards you mentioned are PCI-E 3.0.

    Please make your own forum question next time, since this is non-important for the OP in this one, and he'll probably get a notification like if someone was writing to him. ;)
  5. Oh okay sorry about that ;)
