Thermaltake and SilverStone prepare 3000 W supplies that do not work in American 120V plugs

Building a computer with several high-end graphics cards is no longer just a matter of space in the case or cooling. The real bottleneck, many times, is in the power supply, and that is where Thermaltake and SilverStone have just made a move with two models designed to leave anyone who needs to power several GPUs at the same time without excuses.

Both manufacturers have listed new sources that exceed the 3000 W barriersomething that until recently seemed the exclusive province of professional servers and workstations. The Thermaltake AX 3200W and the SilverStone HELA 3000Rz They share a feature that makes them especially attractive for multi-GPU configurations: four native 12V-2×6 connectors, the standard that ATX 3.1 and PCIe 5.1 require to power the most demanding graphics cards on the market without resorting to adapters or improvised cables.

Four 12V-2×6 connectors to satisfy multiple graphics cards

The Thermaltake AX 3200W meets the standards ATX 3.1 and PCIe 5.1and each of its four 12V-2×6 cables is certified to deliver up to 600W. To that we must add nine 6+2-pin PCIe connectors, two EPS connectors, sixteen SATA connectors and eight peripheral connectors, a display of connectivity that makes it clear that this source is designed for chassis that will house several graphics cards at the same time, whether for rendering, mining or artificial intelligence workloads in home or content creator environments.

The AX 3200W works with a single 12V rail capable of delivering 266.6 A and 3199.2 W, it has the 80 PLUS 230V EU Internal Platinum certification and uses 105°C Japanese capacitors, a detail that is usually synonymous with greater durability against the heat generated by sustained loads. Cooling is provided by a 140 mm double ball bearing fan, and the unit measures 150 × 86 × 200 mm, dimensions that, despite the power it moves, are still reasonable for a high-end tower.

The SilverStone HELA 3000Rz gains 500 W without changing size

For its part, the SilverStone HELA 3000Rz also ATX 3.1 compliant and PCIe Gen 5and its single 12V rail is capable of delivering the full 3000W up to a maximum of 250A. It’s a fully modular unit that includes the same four 12V-2×6 connectors, plus four EPS connectors, seven 8-pin PCIe connections, eight SATA connectors, and four peripheral connectors. For cooling, SilverStone has opted for a 135mm double ball bearing fan, and the measurements remain the same 150 × 86 × 200 mm as Thermaltake’s proposal.

The most striking thing about the leap that the HELA 3000Rz takes is that SilverStone had previously launched the HELA 2500Rzwith the same number of 12V-2×6 connectors but 500 W less power. The new version maintains the same depth of 200 mm, which means that the increase in performance has not translated into a larger chassis, something that will be appreciated by those who have already planned a specific space for the fountain within their tower.

Price and availability, still up in the air

Neither Thermaltake nor SilverStone They have confirmed price and availability date for their respective 3000 W and 3200 W sources. There are also, for the moment, no indications that they will arrive accompanied by a specific communication for the European market, although given that both sources are calibrated for higher voltage electrical networks, it would not be strange if Europe were one of the priority markets in their distribution.

What is clear with this movement is where the high-end power supplies are heading in 2026. The jump to 3000 W, added to the massive arrival of 12V-2×6 connectors, confirms that the next generations of graphics cards will continue to demand more power, and that manufacturers such as Thermaltake and SilverStone are moving forward so that no system with multiple GPUs is left short of watts when the time comes to release the next flagship graphics card.
