Can My 450W PSU handle a 500W GPU

Hi,
I have a 450 W PSU [ CIL - ODYSSEY ] JANUARY 2012 Model no. 450 PA 10091 link- http://www.bazaar99.com/2008/07/odyssey-450w-computer-power-supply-smps.html

And the GPU i am planning to get is
" Sapphire AMD/ATI Radeon R7 250 with Boost R7 250 1GB DDR5 1 GB DDR5 Graphics Card " link - http://www.flipkart.com/sapphire-amd-ati-radeon-r7-250-boost-1gb-ddr5-1-gb-graphics-card/p/itmdqz82gsj4gcmw
Now it needs 500W

The motherboard i am planning to get is "Gigabyte GA-H61M-D2H Motherboard"
link - http://www.flipkart.com/gigabyte-ga-h61m-d2h-motherboard/p/itmd5rrr4fjkzyrx?pid=MBDD5RRR4FJKZYRX&icmpid=reco_pp_recoBundle__tab2_2&ppid=PSRDKFVUQXAD7HUU


Will my PSU work with the motherboard and most importantly will the PSU be able to run the graphic card.

Thanks

    I don't know where they get 500W from. I don't think they even have a power connector - so they don't use any more than 75W from the pcie slot.

    http://www.realhardtechx.com/index_archivos/Page362.htm says 380W which sounds right.
  2. wowowowo hold it! r7 250 is totally NOT worth it, if you are that tight on budget get an HD 7750 GDDR5 version, much better performance for a very similar price
    http://www.tomshardware.com/answers/id-1840450/250-7750.html
    and the 7750 only needs 450w PSU as max (and it will use much less)

    well that is something i am confused about, i asked around this site and people said R7 250x is better than 7750
    And i saw some benchmarks and saw that R7 250x outperformed 7750.
    Though i could use some advice as i am still confused

    Thanks

    that is an R7 250, not an R7 250X and the 7750 outperforms the 250, for example it has more shaders
