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

Just slab 2x8AWG, connect compatible with it, and call it a day.
This is insanity in written form. :p
It's beyond infuriating.
AMD actually does allow board partners to load balance and have WAY more freedom.
1kw GPU and 500w cpu are just around the corner so this just makes sense I guess..
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...
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.
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. :(
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.
The point is 120V is bad in most cases and causes issues/extra expenses for the end user once you get over 1,2kW.
Man, you must really schedule your actions in US, I guess.
For me it's around 0.13€/kWh.
