system power consumption - Corsair link

Jon_39 · Mar 9, 2017

I am running an i7-6700k at stock clocks
rx 480 8gb at stock
16gb of ddr4
3tb seagate barracuda
500gb 850evo
d5 pump
3 ek vardar fans
3 noctua fans

and my corsair rm1000i says that the power draw is at 270W when im stressing cpu, fpu, ram and gpu with aida 64 ...surely that cannot be right ?? all psu calculators estimate at about 550w

That is right. An i7 would only draw up to 100W+ when heavily overclocked. An an RX 480 would only draw ~160W when it too is heavily stressed. Online PSU calculators are just rubbish. Adding the smaller 3-10W for the lesser components and you'll see that the number that your Corsair Link reported is most likely the correct number.

That's why I keep telling people they need a smaller PSU. So many people running around buying 750-1kW PSUs for a single GPU setup. The online calculators have to take into account the cheap/junk PSUs that can only output off the of the claimed power. If PSU calculator said 270W, so a 450W PSU would work, people would be mad when their cheap/junk 450W "max output" PSU gave out. By over estimating how much power is needed they are taking into account the junk PSU. You get problems when you get a quality unit like you have and instead of putting out half it's rated power it's only doing 30% at best.

I will be putting in 2 1080ti's so she'll end up using a bit more power

That would be better IF you get them. Output jumps to 650-700W. Or up to 70% of the rated output. In the mean time the PSU is doing nothing.
