Seasonic and Silverstone Announce Next Generation ATX 3.0 and Gen 5 Ready PSUs Starting at US$230 at 1000W. - Gaming PC guide explained by homebrew users

With next-generation CPU and GPU platforms launching in Q4 2022, PSU manufacturers such as Seasonic and Silverstone are looking to provide best-in-class compatibility and support for the power needs of modern hardware. In addition, we are preparing next-generation ATX 3.0 and Gen 5 compatible products.

Seasonic & Silverstone Preparing Next-Generation ATX 3.0 & Gen 5 PSUs to Meet High-Power Needs of Next-Generation GPUs

ATX 3.0 and Gen 5.0 (12VHPWR) standards are designed to fully support new-generation CPU and GPU platforms and handle the 3x power spikes created by new hardware.

As such, the PSU industry is gearing up to launch next-generation products that can meet the power needs of PCs for years to come.

Starting with Seasonic, they are producing the latest “PS Vertex” series lineup with units ranging from 1000W to 1200W and available in both 80+ Gold and up to 80+ Platinum series.

This PSU is compliant with the ATX 3.0 standard and features one PCIe Gen 5.0 connector, capable of delivering up to 600W of power to the GPU.

Seasonic’s 80+ Platinum series has a fully modular design, while the 80+ Gold series has a partially modular design.

As for pricing, US outlets Tech-America and Provantage have already listed the product.

Prices start at $231 for 1000W Gold and $258 for 1000W Platinum. The 1200W is $267 for 80+ Gold and $304 for 80+ Platinum.

A photo spotted by Harukaze5719 shows that the PSU has a black chassis and a large fan to expel the air.

The lack of gaudy RGB or colorful accents on the PSU definitely helps.

Silverstone has announced the latest PSU “HELA 850R Platinum” with 850W 80+ Platinum design certified by Cybernetics and fully compliant with ATX 3.0 and PCIe 5.0 standards.

This power supply is a standard ATX form factor design with ultra-flexible black flat cables, all-Japan electrolytic capacitors, and 24/7 continuous output (continuous) at 50°C operation.

On the other hand, ASUS also seems to be working on its 1000W 80+ Platinum designed “ROG LOKI SFX-L PSU” lineup, which will come in both white and black color models.

The OEM for the LOKI series is GreatWall and the units are certified by Cybernetics.

This PSU will come in more variants with different wattages, but 1000W seems to be the only option that will be available during launch.

Units range from 750, 850, 1000 and 1200W with up to 80 Plus Titanium ratings and a 10 year warranty.

That said, if you’re planning on building a new gaming PC with the RTX 4090 or RX 7900 XT, you’d better make sure you get a PSU within the respective wattage range of the ATX 3.0 standard.

PSU manufacturers like MSI, ASUS, Gigabyte, FSP Group Thermaltake and Cooler Master are now announcing PCIe Gen 5 and ATX 3.0 compliant designs.

Commentary:

ATX 3.0 compatible 12VHPWR equipped power supplies from male power supply manufacturers Seasonic and SilverStone

As a review, I will attach a list of how much power can be supplied with 12VHPWR and 8PX2 (X3).

Below is my current view which includes speculation.

The highest power consumption so far is 375W for 8PX2, which is probably enough for RTX4070.

RTX4080 may require 12VHPWR for some custom models.

It is better to think that the RTX4090/Ti cannot be used unless it is completely 12VHPWR in terms of power consumption.

RTX4060/Ti below the middle range can be supported with conventional 8PX2 or lower connectors.

Even if the installation is only 12VHPWR, it will probably come with a conversion connector.

Concept for 12VHPWR support

Probably, those who saw the above table think that 12VHPWR is not necessary unless it is 450W or 600W.

But in my opinion it is not.

12VHPWR may be required for models that may require power consumption of 376W or more including OC models.

For example, the RTX4080 has a TBP of 340W, which is probably the TBP of a model that doesn’t OC much.

Higher end models with wider OC range may exceed 376W and require 12VHPWR.

Will 12VHPWR spread?

I honestly don’t think this will be very popular.

The reason is that the power supply that requires 12VHPWR is from 1000W to 1200W, which is not a very popular price range.

It may come out in the 850W class, but I don’t think it makes much sense.

850W-675W is 175W, which is not very realistic.

850W-376W is 474W, but a GPU with 12VHPWR can’t be done with 376W.

Considering that the CPU consumes about 250W, there is almost no margin at 850W.

No matter how much the RTX4090Ti is said to have over 100 TFLOPS and great performance, it will not come in numbers at a price of around 300,000 yen.

I think it has a great presence as a symbol of high performance, but I don’t think there are many people who can buy it.

12VHPWR may be an unfamiliar standard for many users.

When TSMC was at a standstill at 28nm and 4Way SLi, power consumption up to 1500W per outlet, which is the limit of Japan’s power consumption, was discussed, but technological progress has calmed down.

For better or for worse, I think this era was out of balance.

I think that 800W or 900W per GPU is too unbalanced as in the above era, so I don’t think that number will come out that much.

If you use a PC that uses a full 1200W with a single outlet, you will not be able to use any equipment that is hanging on the same series breaker.

The reason is that it is common for PCs to have a large number of devices that consume power, such as monitors and printers.

Also, if you put your life into gaming, you probably have multiple monitors, Xbox, PS5, Switch, and high-grade audio equipment. (bitter smile.

Because the power supply in the room ran out, pulling the power supply from the next room with an extension cord reel is like a conte, and it is not very realistic.

Those who think that 300W has a margin is quite sick. It’s a serious self-made disease.

There are no hospitals or prescriptions that will accept it, so you have to take care of yourself.

In my opinion, the ridiculous power consumption of the GPU this time is too far-fetched.

However, if you are planning to introduce a high-end GPU such as the RTX4090/Ti or RTX4080/Ti, it will be essential, so be sure to include it in your purchase schedule so that you do not have any problems later.
