kayjay010101The day that'll happen is the day we'll see GPUs rated in kilowatts. We'd need a new electrical system as most electrical installations in houses is capped at 230V/10A in Europe or 120V/16A in North America, which works out to 2300W and 1920W respectively, per course. If a card is drawing 1.2kW, then the rest of the PC is probably drawing close to 1.6 (300W CPU, plus some loss due to inefficiency in the PSU and other power draw from SSD/HDDs, fans, LEDs, etc.), which is only 320W off the limit of the breaker. Guidelines say to never exceed 80% usage on a single course, and that number is already 75W over. So when we start seeing 1.2kW cards we'd also probably need to get bigger courses, atleast in North America.
Not to mention the hard limit of 5nm as it seems quantum tunneling is a major barrier to go denser than that in the consumer space and still be able to turn a profit. With 5nm being the barrier, the only way to get anywhere close to 600W+ would be MCM.


Rumors are the FE cards will ship with the required adapter to use 3x 8pin PCIe connectors. So no need for a new PSU or new PSU cable just yet. If we are to believe the rumors, at least.


Rumors indicate they are, and it'll only be for the FE cards. AIB cards will still use traditional PCIe power connectors.


More likely 3x 8pin, as dual 8pin is only capable of 300W, which these cards are rumored to exceed at stock. Hence the new 12pin connector being able to go upto 600W.
