Power Supply Arms Race: Manufacturers Unveil 3000W+ PSUs for AI Workstations

Asus introduces 3000-watt PSU -- enough capacity to power 4 RTX 5090s

Asus just introduced a 3000-watt Asus Pro Workstation power supply unit, which the manufacturer claims has enough juice to power four RTX 5090 graphics cards. The PSU has four 12V-2x6 power ports and also comes with its own etched cables with CPU and PCIe power connectors. More importantly, Asus put all this power in a compact package measuring just 175 mm in length. The Asus Pro Workstation PSU is 80 PLUS Platinum certified, ensuring that the power you're consuming is used to run your computer and not being wasted as heat. At the same time, its fan is equipped with two ball bearings, ensuring that it will last up to 80,000 hours of continuous use -- that translates to more than nine years of being plugged in. Asus also designed the included cables to run 50 degrees cooler than the safety limit, helping prevent the melting connector issue that plagued high-powered RTX 50-series and 40-series GPUs. The cables themselves used pliable cables, making for easier installation and cable management, as well as helping users avoid improper cable seating. This PSU is also PCIe 5.1- and ATX 3.1-compatible, ensuring you can use it for years to come. So, even if you upgrade your components three to five years down the line, you don't have to worry about replacing your power supply because it no longer conforms to the latest standards. This much power isn't designed for the average gamer. After all, a standard U.S. 15-amp, 120-volt outlet can only handle up to 1,800 watts. If you want to use this puppy, you need 25 to 30 amps on a 120-volt outlet to ensure that you don't overload the circuit breaker. Alternatively, you can use a 15- to 20-amp outlet with 240 volts. Asus built this PSU to deliver power for AI computers that require multiple GPUs. We've previously seen 2500-watt PSUs launch at Computex last year, like the HELA 2500R, which is designed to power four RTX 4090s. But as the 5090s require more power, developers who want to take advantage of these more powerful GPUs require a more capable PSU. The average gamer would not need this much power, though. Even if you have three 4K monitors running off a single RTX 5090, and you paired it with the best gaming CPU, 3000 watts is overkill. You're much better off picking one of the best PSUs for gaming -- that way, you can put the extra cash you save towards other accessories. Besides, you don't want to trip your home's circuit breakers by plugging in a PC that uses too much power.

Super Flower shows off not one but two 3000W PSUs at Computex 2025

Super Flower has hit Computex in full force this year, showing off a wide suite of new power supplies and other components for those present in Taiwan. As the OEM behind the success of EVGA's acclaimed PSU line, Super Flower has been making a name for itself in the years following EVGA's soft retirement. And while its new 3300W power supply is the clear star of the show, the rest of its offerings are nothing to sneeze at. Super Flower's "Leadex" badge is where our coverage begins. (As is the case for many PC component makers, it's unclear what, if any, differences exist between Super Flower's Leadex, Combat, and Zillion badges.) The Leadex PSUs are named for their Cybenetics PSU efficiency rating, with the Leadex Titanium leading the pack. Following in the footsteps of the Leadex Titanium 2800W, which launched for pre-order in March, the Titanium 1700W was seen at Computex this year. With a rare Cybenetics Titanium rating, the oversized PSU is ATX 3.1 and PCIe 5.1 compliant. Designed for high-end AI workflows, the PSU is currently aiming for a pilot run to arrive soon. And while the voltage of the 1700W model is a mystery, the 2800W unit requires 240V and ships with a "medical grade power cord", making it likely that the 1700W variant will be similarly overkill. The slightly more down-to-earth options are the Leadex VIII Platinum, the next generation of the standard Leadex line. The VIII Platinums are all fully-modular units with wattages ranging from 850W-1500W and lengths ranging from 150mm down to 125mm, close to the shortest high-end modular units on the market. All come with the Cybenetics Platinum rating, and will ship compatible with the new ATX 3.1 standard. The Leadex VIII Platinums also utilize an interesting Super Flower quirk with the company's 9-pin universal "super connectors." Beyond a motherboard ATX header and one 12V-2x6 header, the remaining ten power connectors are Super Flower's proprietary 9-pin universal connectors. The company has been using the unique design for years -- even spreading it to some EVGA models in the Western market, but the connections still seem shockingly new. No release date was placed on the Leadex VIII Platinum PSUs. Rounding out the Leadex neck of the woods are the Leadex III Gold PSUs, a range of 80 Plus and Cybenetics Gold-certified units. Running from 750W to 1300W, the Leadex III Golds have mostly already hit the shelves, with the ATX 3.1-compatible models ready to ship by June. The Leadex III Gold Pro-A models, which can be seen in the above images, feature ARGB lights coming from the 9-pin headers. Super Flower's new Combat badge, debuted in 2024, reaches down to include some more budget-minded models, but still has some pep in its step. The Combat II FP series is the newest wave from the company, with a 3000W crown. Yes, in addition to Super Flower's 3300W monster that ranks as the largest PSU on the Computex floor, Super Flower announced the Combat II FP 3000W, a Cybenetics Platinum, ATX 3.1 and PCIe 5.1 ready beast. The oversized and overkill model can support multiple 12V-2×6 GPUs for server or enterprise loads and is expected to ship in Q2 2026, likely near the $1,000 mark. The Combat II FP line also includes ATX units from 850W-1200W, all Cybenetics Platinum rated. The FP line's fluid dynamic bearing fans claim an A+ noise rating from Cybenetics, the second-highest score from the Cybenetics labs. Coming with ATX 3.1 certification, the Combat II FP line will begin mass production in September. Just below the FP power supplies is the Combat II FG, a Cybenetics Gold-rated line ranging from 750W to 1200W models. The same Lambda A+ noise rating applies to this line, as well as its ATX 3.1 readiness. The Gold series will begin mass production in November. Finally, the Combat badge has some new SFX options to bring to market. The Combat SFP 850W and 1000W will bring the Platinum rating to SFX, with the Combat SFG 750W and 850W models in the Gold category. Both beginning mass production in August, the SFX models are otherwise stat-matched to the larger Combat II ATX models. Finally, Super Flower's Zillion line is where the budget-minded PSUs come out. The Zillion line is still young, so offerings are light, but not to be ignored. The Zillion SFX Platinum is a Platinum-rated SFX power supply with ATX 3.1 readiness, arriving in 850W and 1000W flavors. With as much connectivity as can be crammed into the micro-sized form factor, the Zillion SFP models will be ready to ship in August, paving the way for the cheaper Combat SFX units. Super Flower also showed off the currently-available Zillion DB and FB series. The non-modular DB series is Cybenetics Silver certified, arriving in up to 850W models, and still carries ATX 3.1 readiness as a new model. With its capacitors made in Taiwan rather than Japan like the rest of the Super Flower family, the DB comes in as the cheapest option shown -- though it's not on shelves in the West. Super Flower's Zillion line also displayed a new case option in the Zillion Direct: an all-mesh-panel mid-tower ATX case. The case uses a patented adjustable slope for directing airflow from the front fans to the GPU intake, seeking to prioritize airflow above all else. The case also includes a GPU support bracket and four ARGB fans to match the built-in ARGB lights. Front panel I/O includes two USB 3.1 connections and one USB-C port, as well as power and reset buttons. The Direct is a nice take on the mesh-forward case design trends of 2025, and is currently available on Newegg for $129.99. The Super Flower booth was a veritable tour de force for the OEM, which has so far failed to break into the U.S. market in a major way since its entry in 2020. With not one but two of the show's 3000+ watt PSUs, a smattering of SFX units, and several of the 50 Cybenetics Titanium-rated PSUs to exist, Super Flower made a convincing argument at Computex this year.

3,000W PSUs are taking over Computex -- Seasonic and Superflower debut behemoth power supplies

As hardware gets more powerful and power hungry, makers of power supplies have to keep up to offer relevant PSUs to interested parties, and to that end, we see even more and more powerful PSUs at every Computex. If last year we thought that 2,800W was crazy, then this year we see that several manufacturers have managed to build 3,000W+ power supplies. Seasonic introduced the Prime PX-2300, a 3,200W 80+ Platinum ATX 3.1 model, at the show, beating Asus's 3,000W PSU that the company showcased earlier this week. The new unit features four 12V-2×6 connectors for high-performance gaming or AI/HPC GPUs, and to that end, it powered a server running four Nvidia datacenter-grade graphics cards and an AMD datacenter processor during the demonstration. Such a setup is common for datacenter environments, though as this is an ATX-standard PSU, it can perfectly fit into a workstation, or even into a gaming desktop, though 3.2kW of power is an overkill for the vast majority of machines that are out there. But as if 3200W is not enough, Super Flower stole Seasonic's thunder with a 3,300W PSU. In fact, Super Flower again displayed the most powerful PSU at Computex -- the Leadex SF-3300F14HP. This 3300W monster is also fully ATX 3.1 compliant, offers five power rails, and is capable of supplying power to high-end processors and four GPUs using four 12V-2×6 connectors. The company expects to start its mass production late this year, so expect its wide availability in late 2025 - early 2026. As for pricing, the company's current-generation flagship 2800W PSU costs some $899. Since the new 3300W does not really replace the previous-gen, but rather enhances the product lineup, expect it to exceed the $1,000 mark. In any case, such high-output power supplies are not universally deployable due to electrical limitations. In North America, typical 120V/15A outlets can only support PSUs up to around 1800W (though keep in mind that the ratings of power outlets are made for peak loads, not continuous loads, so 1600W or less is a more realistic target). So, in the U.S., these CPUs are good for facilities with upgraded power circuits. By contrast, a European 16A/230V outlet (not in all countries and not in all homes, though) can easily support PSUs rated at 3,000W+, depending on efficiency and continuous load. Despite the limited market, demand for such PSUs exists in areas like AI research, custom GPU compute systems, and advanced desktop workstations. Users owning such machines are likely to invest in the necessary infrastructure to support PSUs delivering over 3kW of power, and the cost of infrastructure greatly exceeds the costs of actual PSUs.

Asus continues power supply arms race with new 3,000W PSU that handles up to four RTX 5090s

In a nutshell: Since January, several manufacturers have released power supply units rated at over 2,000 watts - enough to run an air conditioner and far beyond what standard US outlets can handle. Now, Asus has raised the bar with a 3,000-watt model that supports up to four flagship Nvidia GPUs. Asus has unveiled the Pro WS 3,000W platinum power supply, the company's highest-capacity model yet. Packed with advanced features, the unit is the latest in a wave of high-end components built for increasingly power-hungry AI workstations. Thermaltake kicked off this year's PSU arms race in January with the D2000, a 2,000W unit aimed primarily at the European market. Super Flower raised the bar in March with a 2,800W model featuring four 12V-2x6 connectors and a $900 price tag. Then, in late April, SilverStone launched the 2,500W 2500Rz, capable of powering four RTX 5080s or three 5090s. Asus has joined the high-wattage fray with its 3,000W juggernaut, capable of powering an RTX 5090 on its four 12V-2x6 connectors. No one builds a rig like that for gaming - users build them to handle rendering or AI workloads. The "Asus Pro Workstation" label on the PSU's rear panel highlights the growing prominence of these use cases in the consumer GPU market. Like other recent high-power PSUs, the ATX 3.1-compliant Pro WS 3000 supports PCIe 5.1 connections. Each bundled cable delivers up to 600W. Its 80 Plus Platinum rating means it runs at 89 percent efficiency at full load and 92 percent efficiency at half load - one step below the Thermaltake model's titanium certification. Asus included dual-ball bearing fans for cooling, which the company says can last up to 80,000 hours - longer than fluid dynamic bearings and up to twice as long as sleeve bearings. However, the PSU has yet to receive a noise level certification, so the fan noise level remains unclear. Extended aluminum heatsinks improve heat dissipation, while gold-plated copper pins can reduce 12V-2x6 connector temperatures by up to 10 degrees Celsius. The Asus Pro WS 3000 packs its astounding power capacity within an impressively compact 175 x 150 x 86mm shell. Pricing on the company's global storefront is unclear, but the PSU isn't available on the company's US site because American sockets don't support such a high power draw.

Superflower Goes Big With 3300W Leadex Platinum PSU, New Combat & Leadex Designs Plus Cooling Solutions

Superflower has showcased the biggest PSU capacity at Computex, a 3300W behemoth, with all the latest ATX 3.1 and PCIe 5.1 standards. Superflower's Leadex Platinum ATX 3.1 Goes Up To 3300W & Can Easily Run Four RTX 5090 GPUs For Workstation AI Builds Many companies are rolling out their 3000W+ PSU designs at Computex, but Superflower takes the cake for having the highest-rated PSU under its Leadex lineup, which is the flagship product family. The Leadex Platinum ATX 3.1 "SF-3300F14HP 3.1" PSU is a monster, with a Cybenetics Platinum "230V" rating, an ATX 3.1 and PCIe 5.1-ready design featuring full Japanese capacitors and top-tier performance with stable output. This PSU is rated at 3300W and features a large mesh structure on the top and back to vent hot air out of the chassis. The PSU features a single 140mm fan, and we were told that the company did try experimenting with a three-fan solution, but it didn't look nice, hence the use of only a single fan. The PSU comes in an E-ATX form factor with both black and white color schemes. There's also the Combat Dual PSU series, which feature up to 1200W in the form of two 600W PSUs which feature ATX PS2 redundant size, have an efficiency rating of greater or equal to 90% at a typical load, and utilize full Japanese capacitors. Both PSUs share the load, so a 1200W PSU would be split into 600W for each PSU and when one PSU goes bad, the other PSU can sustain the full 1200W. There were also several updated designs within the Leadex, Combat, and Zillion series, including a Mini-ITX/SFF design that offers up to 1200W capacities. Lastly, there were several cooling solutions on display, including 120mm fans that go up to 3000 RPM, the Linkable HyperLink series, which features a locking mechanism that provides the 12V ARGB power, plus the new air and liquid cooling systems.
