Power should handle peaks up to 1800W

We have already talked a lot about PCIe Gen5 power. In fact, the new connection 12VHPWR Allows single cable to transmit up to 600W continuous power. We have already tested one of these power supplies Gigabyte UD1000GM PCIe 5.0. Like the current RTX 3090 Ti, the upcoming NVIDIA GeForce RTX 4000/5000 and AMD Radeon RX 7000 cards will use this connector. But that is what we are learning here Stephen EstmanIntel’s Power Specialist, next gen graphics cards can sometimes claim the pinnacle 1350 watts (For the 3090 Ti given at 450W) 100 ms. So, with An RTX 4090 For example at 600W, lPeak consumption will reach 1800 watts. Specifically, it should be considered that the DGP of the card can be tripled in the short term.

ATX 3.0 Power Supplies: More important than you first think

To handle this properly, you need to pass New ATX 3.0 standard. As we have already explained, current is very primitive in terms of design. We live in a great evolution. With ATX 3.0, the PSU can supply power to other PC components such as CPUs, RAM, and SSDs, as well as power spikes. This is to prevent the PC from malfunctioning due to lack of power in the power supply. So these new generation modules use more powerful and larger capacitors. Similarly, high-voltage blocks are recommended for future graphics cards for this reason, so they can withstand such consumption without moving for the short period of time required.

As we saw during our test, the new cable for PCIe Gen5 has four signal wires. These allow communication between the power supply and the graphics card.

A board manufacturer now knows that it is allowed to push the maximum power rating to 200% of the power supply per 100 microseconds or to push the PSU maximum power rating to 120% for 100 milliseconds.

According to Intel, if you have a GPU with a consumption of 300 watts, a CPU at 300W and 150 watts for the rest of the configuration, well-designed ATX 3.0 power from 750W will suffice. On the other hand, with a module in the ATX 2.X, it will take a module with a power of 1100 watts so that the module can cope with the consumption peak of the GPU. As you can understand, ATX 3.0 power is a major development that should not be overlooked.
