We must start from the fact that a graphics card takes electrical energy to operate from the PCI Express port itself, which provides 75 W of power in combination with a double or single 6 or 8 pin connector. The former provides an additional 75 W, and the latter 150 W. So far, graphics cards consume a maximum of 375 W. However, cWith the arrival of the new 12+4 pin connector, consumption can go up to 675 W with a single connector or if it is doubled up to 1275 W. Although at present there is no graphics chip or video memories that excessively support such consumption.
This translates into new challenges, especially in the relationship between the computer’s power supply and the graphics card. And it is that, apparently, one of the reasons why the RTX 40 would have been delayed is for him misunderstanding with font makers diet and Nvidia
The problem of consumption peaks
There are times when a graphics card can consume double what it normally consumes. These are small peaks lasting a few milliseconds, but at the same time they accelerate the rise in temperature and this can lead to the dry shutdown of said card in the event that one has a lower quality power supply. .
To understand how it works, we must start from the fact that there is a maximum safe temperature, which is lower than that supported by the least heat-tolerant component on the board. When a very high consumption peak suddenly appears, then the security system interprets that the download speed has accelerated and causes a sudden shutdown.
The bone Power spikes occur when there is a sudden change in voltage or amperage. In this case, it is the amperage that rises and therefore the current. so heThe power supply must have the capacity to withstand these sudden surges. Which last very little in time, since they can last a maximum of thousandths of a second and in the best case of millionths.
What does this mean for the most powerful RTX 40?
Well, something many of you may have realized a long time ago is that it will not be possible to install a high-end graphics card that uses the new PCIe Gen 5 slot on power supplies that do not provide a minimum power of 1000 W or more.
However, consumption peaks can be mitigated by using quality components in power supplies that allow us to use power supplies that consume little. This will be the key so that the electricity bill does not increase, of course, these components are expensive and many power supplies, no matter how much power they provide, can end up on a blacklist by NVIDIA, which has caused an internal controversy in which the two parties accuse each other.
Keep in mind that if the RTX 4090 suddenly starts crashing with sporadic crashes, this will be a problem for NVIDIA and its custom card makers and quite a serious problem. Therefore, what appears to be a minor issue may have turned into a nightmare for Jen Hsun Huang.
Who’s right, NVIDIA or the font makers?
Once we have already commented on the issue, we will move on to information that has apparently leaked in various media in recent weeks. Currently NVIDIA would have finished several of the Founders Edition of its future RTX 40 based on the AD102 GPU and therefore on the most powerful GPU in the family. Well, the point is that the RTX 40 would test them with different power supplies with a 12+4 pin connector.
What was the surprise? Without disclosing any brands, NVIDIA has apparently noticed that during peak consumption the card suddenly stops working. This causes crashes in games and even worse, it can render your PC’s power supply useless if it uses poor quality materials. Which made them prepare a list of recommended sources. On the other hand, it caused the various PSU manufacturers to throw their hands over their heads. Several of them are already in manufacturers’ inventories and others in stores. So it’s a huge problem. The way to fix it? Apparently, the RTX 40 would have been delayed for at least a month because of this.
In any case, don’t be surprised to see some RTX 4090 models sold in a bundle with the recommended power supply for the system. Especially with some manufacturers of custom graphics cards, since they are also PSU manufacturers and it is with them that they will be able to test them in complete safety.
