    I wouldn't no. If this is your PSU, it only has a 13a and 14a +12V rails rated for 324W, and only has one 6 pin PCIe power connector for a card that needs 2.

  2. Thank you!
    I just posted to make sure i was not wasting money on the psu, but looks like it is needed
    Probably a Corsair 500w 80+ will do the job.
  3. What about this one ? It has 18A on 12+
    http://tinypic.com/view.php?pic=333ux6v&s=6#.VARiG8NPexo

    CPU: i5 3450

    GPU: Shapphire R9 270X

    Ram: 8 GB

    HDD: 2
    No DVD
  4. Radeon R9 270x needs only 24A
    FSP Group SAGA+ 450R 450W has: +12V1@14A, +12V2@13A
    Can i combin 2 +12 together in 1 ? That would be +12 27A ?!
    Using somthing like this: http://www.amazon.com/StarTech-com-PCIEXSPLIT6-6-Inch-Express-Splitter/dp/B004NNTVT6
  5. No, you can't just add them together to see how many amps you have. You have to know how many watts it puts out on the +12v line(s) in total which for the FSP Group SAGA+ 450R is 324W, then divide it by 12v to get 27Amps. In this case, adding the two 12v line's amps up works out to be the same, but that's not always the case.

    I would consider that one marginal for the R9-270X. Does it even have 2 x 6 pin PCIe power connectors?

    The R9-270X is a 180W card: http://www.hwcompare.com/15657/radeon-r9-270x/
    At +12V, that will draw 15A when it reaches its TDP. Where did you come up with 24A?
  7. 24A when V1 and V2 are combined in 1!

    What about this one ?
    Its again FSP saga but 500watt and gives 18A on +12V1 and 18A on +12V2

    Again... does it have 2 x 6 pin connectors for the card?
    That "500W" PSU has the same +12V ratings as my little Seasonic 300W! So it is not anything I'd consider for a R9-270X. You need a +12V rail that is at least 40+ amps and 480W to be able to run the card and the rest of your system w/o problems.

  10. Well, it does appear to have the necessary PCIe power connections the card requires. But with that small +12V capacity, I don't think it will be a good PSU for the R9-270X. At 408W on the +12V rail, that is only 34A capacity. Personally, I wouldn't use it.
