As the basis of the computer, the power supply is really durable, one refers to physical durability, on the other hand, it refers to the fact that it is less likely to be eliminated due to upgrading.
Do the graphics card to earn a lot of pots, do the power supply can only do part-time to do chargers, sell plugs, rice cooker lines...
In order to fix the bug that the power supply is too durable, the motherboard CPU manufacturer, graphics card manufacturer, power supply manufacturer hit it off, and soon, Intel This ATX 3.0 specification... The PCIE 5.0 power supply specification information and physical objects in have been exposed.
The delayed release of the RTX 3090Ti is said to be the first to use this very different interface.
PCIE 5.0 power supply is longer than the traditional 6Pin, 8Pin PCIE power supply interface, up to 12Pin, but the pin spacing is smaller, so the original two 6 Pins can not be plugged in.
In addition to this 12Pin, there are 4 additional little brothers above it, which is very recognizable.
If you just change the appearance to eliminate the old power supply, it is estimated that you will be scolded by consumers, and the power supply in my hand has 9 years of warranty left, you will ask me to change!
But in fact, in addition to the power supply is too durable, there are more important factors, after reading maybe you have to say thank you Intel.
The first thing that can be seen directly is that the computer consumes more and more power, and naturally needs a higher power supply.
This generation of RTX 3080Ti, 3090 (350W), 3090Ti (450W) alone has no small challenge to today's power supply. It is rumored that the power consumption of RTX 40 has soared, and the next A and N companies seem to have plans for dual-core graphics cards.

Just the simple value of power consumption is fine, the stacking material is ok, 1000W is not enough, then 1500W, 2000W.
But now the power supply interface is indeed limited.
PS effect, for entertainment only
The double 8Pin, three 8Pin scheme is also a simple copy, the increased unnecessary costs will still be passed on to the consumer.
The new 12+4Pin is a tube that provides a 600W rating at its highest level.
Of course, the increase in power supply capacity may only make sense for high-end gamers, but when it comes to the second change, it is related to everyone: PCIE 5.0 power supply will be more strictly controlled power consumption.
When the RTX 3090 exploded frequently, most of them were not due to insufficient power ratings, but because the graphics card would also be emotional, and the instantaneous power consumption soared to several times the rated power, and it exploded.
Even if it is a normal graphics card, there is also an instantaneous power surge, want to experience fried chicken may wish to doughnut grill crazy press space, crazy Thursday is not your crazy.
In simple terms, the PCIE 5.0 power supply specification will more strictly limit this instantaneous power consumption to a reasonable value that the graphics card terminals, power cords, and power supplies can withstand.
Since Nvidia and AMD accept this specification, they will also find ways to reduce the instantaneous power consumption of graphics cards.
Of course, the normal operation of the rated power consumption will also be limited, now the graphics card to give as much power as many completely regardless of whether they can be kept or not, after the power supply can control their own speed before the car accident.
It also controls different power levels from 150W to 600W depending on pin ground (whether connected or not).
The quality of the power supply is largely determined by the material, and therefore uneven, and a wave of garbage power supply takes away the overall computer from time to time.
Although it is a matter of probability whether it is fried or not, if it is not fried, it is 0%, and if it is fried, it is 100%, and no one can say it clearly.
This specification for PCIE 5.0 power supply is an additional protection measure, which alone should be thanked intel, the cause of global warming has been found. After the replacement, it does not mean that the old power supply cannot be used, the adapter will not be more troublesome to do, and I believe that the price of high-power traditional power supplies can also be reduced, but the sense of security brought by the new specification is not felt.
