ASRock Showcases ATX 3.1 & PCIe 5.1 Power Supply Units at CES 2025

[Nomad76]

ASRock is presenting its complete range of power supply units at CES 2025, featuring the Taichi, Phantom Gaming, Steel Legend, and Challenger PSU series. Fully compliant with Intel ATX 3.1 and PCIe 5.1 standards, these PSUs can handle peak power loads ranging from 200% to 235%. They are equipped with 12 V 2x6 cables, capable of delivering up to 600 W through a single cable. Additional highlights include a 5 V BOOST function for improved stability, 100% Japanese capacitors, Infineon CoolMOS, and SiC SBD technology.

The ASRock Taichi series power supply unit is certified for 80 Plus and Cybenetics Titanium efficiency and also received Cybenetics LAMBDA A+ ultra-quiet certification. These PSUs are available in 1650 W and 1300 W models, feature fully modular cables, two native PCIe 12 V 2x6 cables, all-Japanese capacitors, Infineon CoolMOS, SiC SBD, NTC sensor to monitors connector temperatures in real-time and are backed by a 10-year warranty.



Addressing to the needs of gaming enthusiasts, the Phantom Gaming series PSUs offers a wide range of wattage options such as 1600 W, 1300 W, 1000 W, 850 W, and 750 W models. The PSU series have 80 Plus Gold efficiency certification and Cybenetics Platinum & Gold ratings, along with LAMBDA A acoustic certification. ASRock Phantom Gaming features a fully modular design, native 12V-2x6 connectors, premium all-Japanese capacitors, NTC sensor to monitors connector temperatures in real-time and a 10-year warranty.



The Steel Legend series power supply units are available in "Steel Black" and "Steel White" variants, housed in a compact 150 mm casing with a fully modular flat cable design. They come in 1000 W, 850 W, 750 W, and 650 W models. The series is certified for 80 Plus Gold efficiency and Cybenetics Platinum and Gold ratings, along with LAMBDA A+/A/A- acoustic certifications. Each unit is backed by a 10-year warranty.

1650w holy...
I was going to ask how people manage to use that much power with SLI being dead, but right... it's probably still for multi-GPU but instead in the AI realm.

What is the 5V boost for?

 

[ErikG]

Keeps the 5v from drooping too low, if you have a lot of storage devices etc.

And it needs a button for that? Oh well

Let's hope they send TPU a unit to test. ASRock has never let me down as far as quality goes, would love to use their PSU's assuming they've built them right.

what is another 2-pin connector for?

5090 TI J/K , i think in case you want to use two RTX cards.

Edit: ah , the little 2 pin , got confused

 

[Bobaganoosh]

I wonder who the OEM is. The only other supply I could find with that voltage sense with the 12V2x6 connectors is an ASUS.

what is another 2-pin connector for?

It's probably for voltage sense on the other end of the cable. If you have a high-impedance pair of wires going to a sense circuit, those don't allow any current flow, so there's no voltage drop on those wires and the power supply can get an accurate reading of the voltage at the GPU connector. This can then be used to improve stability of the 12V rail.

Edit: this guess turned out to be incorrect, but was based on what others (ASUS) were doing and a fairly common power supply technique in other industries/applications.

Some temperature protection sensor I think.

Edit: yes.

Nice. This should shut down a melting connector cable.

I wonder who the OEM is.

Steel Legend - HEC
phantom line & Taichi - FSP

I have fully modular PSUs for some time, and I failed to see the point the Mainboard and recently the first12VHPWR being detachable, especially with the 12VHPWR's reputation.
That two will be used in the 99.9% of the cases.

I guess its "why not" for the price / psu class i have a semi-modular PSU , the MB cables are not detachable and its super fine.

 

[Rightness_1]

750w to 850w is more than enough for 96% of mid to high end gaming builds. But with the 5090 I hear that the recommended PSU is now 1000w.

But the way the whole ATX3.1/PCiE5.1 thing has been dealt with is just insane. I want one now, and only a handful are on the market, and they are often just an updated model sold on the same SKU, which is leading to massive confusion on most online shops still having ATX3.0 versions of the same PSU on their sites and in inventory.

By spec, every 3.0 certified modular PSU becomes 3.1 if they use the revised 12V-2x6 connector instead of the original 12VHPWR on the PSU side. Electrically speaking, 3.0 is harder to achieve.
