    Default Seasonic SS 1050XM 1000watts power supply

    hi, i am upgrading my pc graphic card to 2 Sapphire AMD/ATI Radeon R9 290 TRI-X OC in crossfire & with that i also need to upgrade my Psu(smps) because currently i am using some 750 watts PSU. i decided to go with Seasonic SS 1050XM 1000watts 80+Gold psu.
    My problem is that i don't know that what kind of PSU is this one or is it a continuous power supply or is it going to be sufficient??.

    My Rig.
    processor :: Intel 4770k (not overclocked)
    mother board :: Asus Maximus VI fromula
    Memory :: G.skill 16gb 2133 Daul Channel Kit.
    Graphic Card :: Sapphire AMD/ATI Radeon R9 290 TRI-X OC In crossfire
    HDD :: Scandisc 256gb SSD + 1TB WD Black + 3TB WD Green
    corsair H80i
    6 Fans & a fan controller.
    Thank You

    A single radeon 290x tri-x oc will use about 260-300w, with occasional spikes of a few milliseconds where they go to about 350w.

    Two of them will use about 600-650w on 12v.
    The rest of your system iwll use about 150w on 12v.

    The Seasonic 1050XM is capable of delivering 1044 watts on 12, which is more than 800w (650+150), so it should be more than enough.

    Without OC a good 750W is more then enough.
