Jesi probal vratiti natrag 13600K s kojim je sve bilo kak spada?

GPU and PSU wattage must be taken into account as well - a 600W load requires a 1200W rated CORSAIR PSU or higher. 450W load requires 1000W or higher. customers can now order official CORSAIR 12VHPWR 600W cables compatible with all CORSAIR type-4 PSUs, connecting directly to the PSU via the existing PSU-side connectors for unfettered power straight for your new graphics card – no PCIe adapter required. With sense-wires configured to 600W, your graphics card will know it’s able to draw its maximum power load.

nVidia RTX 4090: 450 W vs 600 W 12VHPWR - Is there any notable performance difference?

Citiraj:

There is a slight difference between the 450 W and 600 W connectors at overclocked speeds, but with this specific RTX 4090 implementation, the increase in power spikes means that the VRMs are pushed hard. Given that the average gaming power consumption of an RTX 4090 is around 350 W, it doesn't make much difference whether you use a 450 W or a 600 W 12VHPWR connector. If you plan to overclock the card hard, notably decreasing its efficiency, using a 600 W 12VHPWR connector will make a difference since it will allow the card to draw more juice. The lower temperatures under stock and OC speeds with the 600 W 12VHPWR connector, compared to the 450 W one, are most likely to do with the card's VRMs, which operate better with the full capacity of the 12VHPWR connector. It seems that the 450 W limiter, when Sense0 and Sense1 on the 12VHWR connector are set to open and ground, affects the VRM's operation, increasing ripple as the limiter is engaged, leading to higher GPU temperatures.
