The power supply this thing is easy to let the novice DIYer or even some veteran pit accessories, the recent new high-end power supply added a new PCIe 5.0 power supply interface, in addition to stronger performance, but also for everyone to dig a new pit. When changing the power supply, I thought that the interface prepared for the next generation of graphics cards may not be enough at that time. This is what is going on, just change the power supply or prepare to buy the next generation of high-end graphics cards of the small partners to see it.
First of all, the so-called PCIe 5.0 power supply interface is actually nothing to do with PCIe 5.0 itself, it is an interface that assists the power supply of high-end graphics cards, but it is expected to be popularized in the next generation of graphics cards, that is, high-end graphics cards that support PCIe 5.0, and only then has this "synonym". Its "basic form" is a 12-pin plug, and the slender arrangement looks similar to that of the RTX 30 series public version. Its "goal" is to provide 600W of electricity.
Seeing here does not seem to be a problem, in fact, it is not, because the basic form is not the "final" or "newest" form, let alone the target form, so well... The actual power supply capacity is 450W. What is the level of this power supply? Let's take a chestnut, RTX 3090/3080 Ti/3080 12GB power consumption is 350W Oh, the next generation of graphics card well, it is said that the power consumption of high-end products is at least 450W.
Obviously, even if there is a slot to provide nearly 100W of power, the next generation of high-end graphics cards with 450W auxiliary power supply is very reluctant, and the over-frequency is even more insufficient. So the real PCIe 5.0 power supply interface came, and the change was that under the front 12Pin interface, a very inconspicuous 4 small pins were installed.
Therefore, when buying a power supply that hopes to support high-end graphics cards in the future, we not only have to look at the "support for PCIe 5.0 power supply", to confirm that there is a 600W power supply capacity, there must be the following points in the publicity, description, and labeling. The best of course is to directly mark the power supply capacity, and then the number of pins marking the interface is 16Pin; in addition, the 600W PCIe 5.0 interface has a special standard, that is, 12VHPWR, which can be marked on the interface or cable, so that the power supply is more trustworthy.
