Seasonic has presented the two new top models in the Prime TX and Prime PX series with 1,600 watts and two 12VHPWR connectors. With this, the manufacturer is already taking into account the probable development of the power loss of future graphics cards. AMD's RDNA 3 and Nvidia's Ada are said to be thirsty.
2×12VHPWR per cable whip
Seasonic is expanding its portfolio of high-end power supplies with 80Plus Platinum and Titanium certification to include two new top-of-the-line models with 1,600 watts and is already serving with two 12VHPWR plugs via breakout cable (2×8-pin from the power supply to 1×12VHPWR). today the upcoming graphics card series AMD Radeon RX 7000 and Nvidia GeForce RTX 4000, which will face the duel for the GPU throne by the end of the year at the latest. Intel's first dedicated graphics card generation, the Alchemist, is not yet ready for a real three-way battle.

Which of the sometimes wild speculations in the rumor mill that the hybrid “chiplet GPUs” based on RDNA 3 and the monolithic Ada graphics processors have TDP and TGP ratings that fluctuate heavily almost every week from 450 to 900 watts, remains to be seen – but it is no longer a secret that the peak power consumption will increase significantly again.
ComputerBase has already dealt with what that means in detail.
