Can 750 watt run dual gtx970? If not, do i need 2 change over 1k watt psu? Planning 2 target my next project upgrade in june next year. GST cost i am willing 2 absorb like a boss.

good old sliverstone zeus since 2006

is 1k watt overkill 4 the single GTX980? my psu is dying with constant auto shutdown while playing games and even while watching youtube after 8 years of service. so i plan 2 change together with cheap second hand GTX980 in the future.
