Hey fellas, I was thinking to put another 980ti to my PC, but I have only 750W Super Nova G2 Power Supply. In Calculator it shows me I need Recommended PSU Wattage in load 729 W. I have 4790k, 16GB RAM DDR3, 4HDDs and one SSD(system). I have NZXT Kraken X41 and my 980ti is watercooled from Gigabyte. All in NZXT h440 case with 3x 120mm fans in front, gaming keybard and gaming mouse. I powering up 3 screens 1080p. Do you think I will really need new PS or I should be ok with mine now without any OCing ? Thanks for your answers :)

ya, like blackbird said at minimum a solid 850w my 980 ti at full load sucks 280w and some cards bios are higher then that limit like 400w

980ti classy

Board power limit
Target: 300.0 W
Limit: 425.0 W

980ti

Board power limit
Target: 250.0 W
Limit: 275.0 W

zotac amp extreme 980ti

Board power limit
Target: 390.0 W
Limit: 435.0 W

then i'll bet you want to overclock them as well plus x2 ???

then add any cpu overclocking that 4790k could draw up to 100w over its stock 85 . things start to add up quick and AMP's get to be a premium

good luck

I would do a grand / 1050w at least my self

so you figure at full load 2 cards pulling 390w + 90 for your cpu oc just that = 870w at 72.5 amps right there easy . that maxed out that 850 w psu @ 70amps at the 12v , now what ???
