Original title: the power of N card has exploded? RTX30 graphics card installed power supply strategy source: Tencent News

RTX30 series graphics card finally came, this time NVIDIA's new flagship card is not what we think of RTX 3080Ti, but RTX 3090, although the graphics card has not been officially obtained, but to see a substantial improvement in graphics card parameters, coupled with the friendly price, so that players all over the world say: NV this time conscience.

First of all, in terms of performance, NVIDIA officially claims that the performance per watt of NVIDIA Ampere architecture is 1.9 times that of Turing. Lao Huang said on the release that RTX 3070 is faster than RTX 2080Ti, which is exciting to think about. You know, the CUDA core of RTX 3080 is more than 100% higher than RTX 2080Ti, nearly 3 times more than RTX 2080, even RTX 3070 has more CUDA cores than RTX 2080Ti, and RTX 3090 is even more grandiose, with CUDA cores exceeding 10,000!

Although the specification performance explodes the table, but after the introduction of Samsung's new 8nm technology, coupled with the "straight-through" heat dissipation design, RTX30 series graphics cards are bound to have better performance than RTX20 series graphics cards in terms of power and heating. If the thermal power consumption of TDP of RTX2080Ti and RTX2080 is 260W and 225W, then the power consumption of RTX3080Ti and RTX3080 will probably not exceed the former. Coupled with ten generations of i9-10900K or Ruilong R9-3900XT flagship CPU (TDP thermal power consumption in 125W/105W), graphics card and CPU power consumption of two major power users TDP maximum 385W, then equipped with a rated power level 650W power supply, basically enough. Of course, with conditions and budget, it is recommended to go up to the 750W and 850W level, and the operation will be more stable when overclocking.

I estimate that many players are on hold at this stage, waiting for the RTX30 series graphics cards to be officially released (the first graphics cards are expected to go on sale on September 24). If you want to choose a good power supply for RTX30 series graphics cards in advance, then XPG CR series high-end gold module power supply is a good choice: 80Plus gold certification, low-noise design, full-day capacitance, altitude 5000 meters certification, full module design, ten-year warranty …... Provide reliable and stable power supply for RTX30 series graphics cards.

There are three models in XPG CR series, which are CR850G, CR750G and CR650G, corresponding to 850W, 750W and 650W. If you choose a RTX3080Ti-level graphics card, I recommend that you consider CR850G;. If you are a high-end positioning card in RTX3070 and RTX3060, you can consider CR750G and CR650G.

XPG CR650G, for example, has passed the 80Plus gold certification, and its power conversion efficiency has reached 92%, close to the platinum level. It adopts single channel + 12V output, and the output current can reach 54.1A, which is equivalent to 650 rated power output. The maximum output current of + 5V and + 3.3V is 20A, the maximum standby output of 5V is 3A, which ensures the power supply demand of CPU, motherboard and other hardware.

The overall structure of XPG CR650G is active PFC+ half-bridge LLC resonance + synchronous rectifier + DC- DC, the fan uses Honghua's FDB hydrodynamic bearing fan, the overall mute effect is good, while there is a special chip to drive the fan, dynamically adjust the speed of the fan according to the internal temperature of the power supply, taking into account the temperature and noise. The electrolytic capacitors and solid-state capacitors inside the power supply are all big brands of the Japanese system, and the number of capacitors is sufficient.

As the first power series of high-end e-sports brand XPG, the XPG CR series has a high start. From these ten years of warranty can pry one or two, there is no high-standard workmanship materials, who dares to give such a long warranty life? Ten years later, the entire RTX30 series graphics cards may be eliminated, and the power supply will be able to fight again.
