r9 270x crossfire question

i would like to know if ym psu would be ok for crossfiring two of the above cards (both would be the msi twin frozr 4gb OC editions)
my psu is a thermaltake 80+ bronze 630w (or maybe 650w - i need to double check the box) Berlin model

cpu: fx 6300 @4.4ghz
cooler: alpenfohn matterhorn pure
mobo: asus m5a97 r2.0
ram: 8gb gskill ripjaws @ 2133mhz
case: zalman z9 plus w/ 4 fans in, 3 out
hdd/cd rom: basic ones lol

thanks in advance.

p.s i know the mobo is not a "proper" crossfire/sli card, but from what i have read, x-firing these cards with one in X4 will only cost a small drop in performance over 2x X16

  1. See "Best Solution" post in this thread: http://www.tomshardware.co.uk/answers/id-2034660/tr2-600w-psu-run-crossfire-270x.html

    According to that you need a 750w PSU.

    I can't answer your question regarding having one of the cards in a PCIe x4 slot, except to say that some x4 slots are shorter than x16 slots, in which case the card won't fit in it. It depends how the x4 slot is wired up. See the post from Pinhedd here: http://www.tomshardware.co.uk/forum/356410-33-card-motherboard

    The Thermaltake Berlin 630W has insufficient +12V rail capacity and an insufficient number of PCI Express supplementary power connectors to power a system with two MSI R9 270X GAMING 4G graphics cards.
  3. thats a junk powersupply id upgrade it before id even consider a crossfire.

    whats your budget for the cards and powersupply and do u already own a 270x.

    budget is as little as possible (or as much as i can hide from the wife)

    yes i own one 270x already, and crossfiring seems cheaper than upgrading to an equivalent single card.
  5. i need a specific budget to work with
