Old power supplies can be dangerous to use with new graphics cards. If you need a 12VHPWR connector, then it’s better to buy an ATX 3.0 block

The PCI-SIG organization warns that using old-style power supplies to connect to the new 12VHPWR connector on video cards through adapters can be dangerous.

Old power supplies can be dangerous to use with new graphics cards.  If you need a 12VHPWR connector, then it's better to buy an ATX 3.0 block

Power supplies that do not comply with the ATX 3.0 standard can be connected to very powerful video cards in two ways: directly with three eight-pin connectors, if the adapter is equipped with them, or by using an adapter from three of these connectors to one new 12VHPWR. In the first case, there will be no problems, but in the second they may be.

The reason is as simple as possible. The 12VHPWR connector is designed for a maximum load of 600W, while each eight-pin connector is only capable of transmitting 150W, that is, three of these connectors provide only 450W of power. If the card consumes much more, this can lead to disastrous consequences. At the same time, there are already adapters on the market from two eight-pin connectors to one 12VHPWR.

Be aware that PCI-SIG has become aware that some implementations of the 12VHPWR connectors and assemblies have exhibited thermal dispersion, which can lead to security issues under certain conditions. While the PCI-SIG specifications provide the necessary information for interoperability, they do not attempt to cover all aspects of good design, relying on numerous industry best practices and standard design practices. Since the PCI-SIG Working Groups include many knowledgeable experts in the field of connector and system design, they will study available information about this industry issue and provide assistance in any resolution as needed.

As new details become available, PCI-SIG may provide additional updates. In the meantime, we encourage members to work closely with connector suppliers and exercise due diligence when using high power connections, especially where security concerns may exist.

Ryzen 9 7950X at 6.5 GHz consumes as much as a non-overclocked Core i9-12900K

Ryzen 9 7950X at 65 GHz consumes as much as

The Ryzen 9 7950X processor continues to impress with advances even before it hits the market.

Ryzen 9 7950X at 6.5 GHz consumes as much as a non-overclocked Core i9-12900K

This time the processor showed how energy efficient it can be even with extreme overclocking. So, the Sampson overclocker managed to overclock the CPU to 6.5 GHz for all cores using liquid nitrogen.

And at such a high frequency, the processor consumed only 270 watts. For comparison, the Core i9-12900K requires about the same amount without any overclocking, just under maximum load. The Core i9-13900K, when overclocked to 6.2-6.3 GHz, requires about 400 watts.

With such overclocking, the new AMD scores more than 48,200 points in Cinebench R23, and in Cinebench R20 the result reaches 18,605 points. There is also a result from another source with overclocking to 6.7 GHz and 50,395 points in Cinebench R23.

Recall that the Ryzen 9 7950X will be on sale on September 27th. Intel on the same day will introduce its Raptor Lake processors, but they will not go on sale until October.

Intel is finally ready to release its top end Arc graphics

It looks like we finally have the exact launch dates for the older Intel Arc graphics cards.

Intel is finally ready to release its top-end Arc graphics cards.  Reviews due October 5th

There are reportedly at least two dates for the Arc A770. First, unpackings of the adapter will be published on September 30, and then on October 5, thematic resources will be able to publish reviews as well.

Earlier, Intel itself said that the Arc A750 will be released along with the A770, so, apparently, the indicated dates are also valid for the younger card. But there is no data about Arc A580.

In addition, it is expected that on September 27, the day of the announcement of the Raptor Lake processors, Intel can share new details about the graphics cards. In particular, to finally name the prices, which she promised to make very competitive.

Recall that the top Arc A770 is reportedly capable of competing with the GeForce RTX 3060 and RTX 3060 Ti.

GeForce RTX 3090 is everything. Nvidia is phasing out the Ampere line of flagships

GeForce RTX 3090 is everything Nvidia is phasing out the

Even before the official premiere of Nvidia Ada Lovelace video cards, there were rumors that after the premiere of new products (and, in particular, the GeForce RTX 4090), Nvidia might discontinue the production of the GeForce RTX 3090, and it all happened: there is no place for GeForce in the current Nvidia line RTX 3090. Moreover, the age of the GeForce RTX 3090 Ti turned out to be short-lived.

GeForce RTX 3090 is everything.  Nvidia is phasing out the Ampere line of flagships

This is what the current line of Nvidia 3D cards looks like after the announcement of the GeForce RTX 4090 and RTX 4080

If the GeForce RTX 3090 has lived quite a long life, then you can’t say the same about the GeForce RTX 3090 Ti. At the same time, this model performed the important function of a test platform for the GeForce RTX 4090. Well, since the GeForce RTX 4090 is already officially presented and will go on sale pretty soon, then there is no point in it: the current and previous flagship would simply compete with each other, which clearly not in the hands of Nvidia.

However, the fact that the GeForce RTX 3090 and RTX 3090 Ti are discontinued does not mean that these models will immediately disappear from sale. They will be available for purchase until stocks run out. Even now, these models are presented in the official Nvidia online store.
