Seasonic Shows 3,200 W PSU, 16-Pin Connector Cooler, and Advanced Surge Protection at Computex 2025

[AleksandarK]

At the Computex 2025, Seasonic introduced a range of advanced power solutions for desktop PC performance and reliability. The real standout piece was the PRIME PX-3200, a fully modular 3,200 W power supply compliant with ATX 3.1 standards. This unit delivers 266.7 A on its single +12 V rail and achieves up to 94% efficiency under typical loads, earning 80 Plus Platinum certification, alongside TechPowerUp Best of Computex 2025 award. It can provide its entire power capacity to a single rail, designed for extreme overclocking scenarios. Key features include Micro Tolerance Load Regulation (within 1 %), premium Japanese 105 °C electrolytic capacitors, gold-plated high-current terminals, and a 12-year warranty.




Building on its reputation for thermal innovation, Seasonic unveiled OptiSink 2.0. This next-generation heatsink design improves heat conduction by up to 30 percent through optimized fin spacing and a reconfigured PCB layout accommodating compact MOSFETs. The result is quieter operation and greater long-term reliability. In tandem, OptiGuard adds targeted protection for the graphics card rail, reacting to over-voltage, under-voltage, and spikes within microseconds to preserve GPU health.

Seasonic also teamed up with hardware reviewer King of Wing to launch the 12V-2×6 Ti smart power cable. It offers real-time per-pin voltage and current monitoring, an integrated temperature sensor with an audible buzzer, and the ability to trigger a GPU's own shutdown protection under fault conditions. Builders can further customize this cable with optional heatsinks, fans, and solder configurations, and an external display module keeps vital data in clear view.

In addition to performance and protection, Seasonic emphasized personalization and flexibility. The company's Colorways series features swappable housing panels in multiple finishes, allowing users to coordinate their power supply with any build theme. The CORE Dual power supply offers universal mounting options—horizontal, vertical, or inverted—making it an ideal choice for unconventional or compact chassis designs.

Finally, in collaboration with Noctua, Seasonic unveiled the PRIME HPD PX-1200 Noctua Edition. This 1,200 W unit combines OptiSink enhancements with Noctua's NF-A12x25 G2 PWM fan to deliver whisper-quiet cooling, Micro Tolerance Load Regulation within 0.5 percent, ripple noise below 25 mV, and active power factor correction up to 99 percent. It carries a 12-year warranty and targets silent-PC enthusiasts who demand the very best in performance and acoustics.

16-Pin Connector Cooler??!!

 

[Kwadratowicz]

Yay, make the problem that did not existed, and now companys are making stuff to mitigate the problem, and sell it to customers, and main culprit is just gaining money...
Just slab 2x8AWG, connect compatible with it, and call it a day.

Regardless if problem is actually statistically relevant or not (debatable), the fact the fear of a problem exists means there is an opportunity to provide a solution. Normal economics.

 

[Vya Domus]

RTX 60 series compliant I suppose.

This is insanity in written form.

This shows how far NVIDIA has pushed everyone into a corner with their daft ideas that are set in stone. All these bandaids shouldn't be needed if NVIDIA didn't act like this.

It's beyond infuriating.

AMD actually does allow board partners to load balance and have WAY more freedom.

 

[R-T-B]

Can we talk about Seasonic and not that connector, or is that impossible?

 

[Dirt Chip]

3.2kw is about the maximum you can safely suck from a normal, 1 phase power outlet, at your home..
1kw GPU and 500w cpu are just around the corner so this just makes sense I guess..

Isn't a cable with an integrated temp sensor, a buzzer, GPU shut down option and heatsink compatibility a product we have all been waiting for for all these years? This is Ultimate PC Master Race!

Honestly that is the thing that looks interesting to me.

Not sure where you live... you'd have to have a 30A breaker serviced on your 120V line which would require 10AWG line running to your outlet... no thanks... Most I've ever seen in a home is 20A on 12AWG which is more standard, typically its 14AWG for 15A. Anything in the 1700W+ territory and you'll be looking at tripping the breaker every now and then. But that's besides the point...

This amount of power for a computer is nuts... what happened? I thought things were trending toward more energy efficient??? I mean this is like NVIDIA FERMI+++++ now in terms of power draw from GPUs. Pretty wild what's happened this gen...

 

[LittleBro]

Holy damn crap. Even mighty Seasonic went down the road for that diseaseous connector.

Instead of teaming up with others and developing new and proper connector, they decided to implement various monitoring.
You even get external display, so you can keep your eye on your pin currents. Instead of keeping eyes on monitor.
This, yet again, does NOT solve the problem, only prevents possible melting outcomes.
Introducing a cable with mechanism that can balance current between pins would be a solution, to something that is still a problem, but at least a solution.

FFS, take than piece of shit connector, scale it to 1.5x it's size, release it and call it a day.

Builders can further customize this cable with optional heatsinks, fans, and solder configurations, ...

Well, the evolved part of the world uses 220-230V and 10A-16A breakers as standard in-house no extra, nothing special or out of the norm.
So basically 220V * 16A = 3520W without accounting for heat losses. But yeah, 3kW per breaker is nothing special in a standard European household. I always feel sorry for the US electrical system.

 

[PixelTech]

12v-2x6 connector is too small. And GPU card manufacturers don't have the freedom to provide electrical protections between the connector to the board.
What I think a lot people miss is that there is the 4 sense pins that are there for the GPU and PSU to talk to each other about what wattage the PSU can provide and if the connectors are plugged in all the way. But when u have such a weak small connector there's wiggle room for the sense pins to still be connected, but the pins inside the connector to be pushed in and short!
No wonder ASUS and MSI are putting development money into their BTF and Project Zero connectors. But it won't work if all the mobo/gpu manufactures can't collaborate.

We have 230v, 16A as standard rated for max 3500w (theoretical 3680w) like in most Europe (I think)

You know it's good, if its start to melt you can breathe more air to the newborn flames

Further affirmation that the standard is trash. I cannot think of another cable standard that required these extreme measures just to make sure a part doesn't melt itself.

pretty much, why should we bend over backwards to acomodate nvidia when the previous 8 pin standard could have just safely added a 3rd connector and called it a day

We have 120/240V single phase typically for residential use, but if you want to pay, the power company can install 120/208V or 277/480V three phase services...

Cool, here you can get 3 phase 230V for residential use ... so you can go up to around 690V with 20kW of power. But yes, you have to pay extra for that and the cables from the transformer to your house/building usually need to be replaced to handle the load, so it's not really feasible for someone that's not making buckets of money and have the need for that much power.
The point is 120V is bad in most cases and causes issues/extra expenses for the end user once you get over 1,2kW.

Just one phase for stove, vacuum cleaner, boiler, dishwasher, washing machines, fridge and water kettle?
Man, you must really schedule your actions in US, I guess.

25A over here, but 220V line, and that's for the whole place. I'm not sure if any power outlet here in particular is good enough for 3200W. 2000W sure. More than that no idea.
