Kilowatt power is not enough 4090 may take 1200 watts of power

Now the performance of computers is becoming electric tigers. More than a decade ago, the era of 300 watts everywhere has long passed, and now it can't move the graphics card, and the new 4090 is said to have further increased the requirements for power supply.

Previously, it was announced that the large core number of the 5nm Lovelace architecture will be AD102, there will be as many as 12 GPC (graphics processing clusters), 72 TPC (texture processing clusters), 144 SM (streaming multiprocessors), and each SM continues to have 128 stream processors (CUDA cores), then the overall number of up to 18432 stream processors, compared to the current ampere architecture GA102 core of 10752 cores increased by 71%, Double overall performance.

However, at the same time as the performance has soared, the power consumption of the RTX 40 series graphics card is also soaring, after the news said that its Total Graphics Power entire card power consumption is not less than 550W, which is 200W higher than it is now.

While the power consumption of the graphics card has risen sharply, the requirements for power have also increased, and the latest news says that the RTX 4090/Ti graphics card with a 1000W power supply is no longer enough, at least 1200W power supply.

In the past, the power supply of more than kilowatts did not intersect with mainstream DIY players, but with the arrival of a new generation of graphics cards and processors, this may have to become daily, in fact, do not have to wait for the next generation of products, CES released on the RTX 3090 Ti graphics card recommended power supply is 1000W.

If you are ready to upgrade the full PC platform at the end of this year, it is necessary for high-end players to consider the 1500W power supply on the market.
