FSP launches multiple new ranges for 2026
FSP is one of the longest-established power supply manufacturers in the PC industry, with decades of experience producing PSUs both under its own brand and as an OEM partner for a wide range of well-known companies. Its manufacturing spans high-volume consumer products through to industrial and enterprise-grade power solutions, giving FSP a perspective that extends well beyond the retail PC space. As part of the EHA Tech Tour, KitGuru was invited to FSP’s main office in Taipei to look at several new products coming to market in 2026.
We first visited FSP’s Taiwan factory back in 2018, back when they were creating the CC1 power module, intended for crypto mining rigs. Fast forward to 2026 and FSP is now introducing the Cannon Pro 3300W.
In the UK, a typical household electrical supply uses a 230V single phase supply with sockets rated at 13A, translating to roughly 3,000 watts at 230V under ideal conditions. Running a system that can legitimately draw close to that limit continuously is not something most domestic installations are designed to do. We would never recommend any of our readers take close to 3,300 watts from a single plug socket in a home, even though in theory it could be fine. These workstations are destined for commercial environments where three-phase power is the norm.
Something you will hear more and more about in 2026, is an emerging concept called ‘desktop sovereign AI’. These are powerful, locally hosted AI systems (for example inside a workstation-class chassis), that allows organisations/departments to develop and run models locally – keeping any data, training and outputs under total control – without relying on external cloud services. The FSP Cannon Pro 3300W has the ability to support the hardware in such a system – with a ‘fully loaded’, single chassis workstation costing anywhere from £20,000 to £120,000.
Why is FSP so focused on AI-capable power supplies? Well, according to the data they presented, the demand for AI-capable PCs increased past 55% in 2025. When investing so much into new systems, uptime becomes crucial and we were shown a number of PSU products that have been designed with redundancy/hot-swap capabilities.
Back in 2017, FSP launched the 700W version of this PSU with Gold efficiency. It’s a way to get a pair of ‘SFX-type’ PSUs into a single/standard size PSU external housing. This was the TWINS 700W version. The idea has continued to develop, and the latest iteration is the TWINS Pro 1400W. The efficiency rating has gone up to Platinum, and the overall unit is on the deep side. It is 150mm wide and 86mm high, but the depth is 220mm – as opposed to the 180mm you might normally expect on a large PSU. It supports PMBus and USB port functions with fan failure protection and active PFC.
Focusing on size, the FlexGURU 650W is a lower-cost, smaller form factor power supply that still delivers up to 650 watts with efficiency levels that peak at Gold level. The external dimensions are 81.4mm x 40.5mm x 150mm. FSP claims that even with this compact design, they can offer 100,000 hours (over 11 years) mean time between failure in a 25-degree ambient environment. Given that 100% of these units shipped by FSP will undergo/survive the kind of Hi-Pot (lightning) test we saw on a previous visit – their confidence is probably well placed. Although exact figures were not available when we saw the product, FSP claims that it will be at a ‘surprisingly low price’ for the specification.
It seems that, in 2026, Gold efficiency really is the new entry level.
FSP’s MEGA and DAGGER ranges will also be getting an update.
The MEGA GM range of fully modular power supplies comes in 850W, 1000W and 1200W versions, aimed at gaming and high-performance PCs, with Gold efficiency ratings and support for the latest Intel ATX 3.1 and PCIe 5.1 standards. FSP believes the MEGA GM units exceed the ATX 3.1 spec, using its proprietary MTLC (Micro Tolerance Load Control) technology. MTLC should increase the lifespan of high-end CPUs and GPUs, according to FSP. MEGA GM power supplies are ‘fanless' up to 50% load. As the draw passes 50%, the fan system ramps up smoothly, emitting less than 15dBA. Overall, this PSU is fully modular with embossed cables. UK pricing is expected to be around £160 for the 850W version, with the 1000w and 1200w coming in closer to £179 and £199 respectively.
Top of this particular line-up is the MEGA TI, which comprises a 1250W and 1650W supply with Titanium rating. Both have dual native PCIe 12V-2×6 connectors and cables. This also features the semi-fanless design – promising zero noise when pulling under 50%.
The DAGGER small form factor products that we first reported on back at the start of January 2024, have now received another update and the 1200W unit now offers Platinum efficiency with Japanese bulk capacitors. The FSP product managers seemed very happy that they’d achieved Platinum in a smaller unit.
In terms of chassis products, FSP has a full line-up for 2026 with:
- Six high-end gamer/enthusiast cases: M580, U691, U580, M580 Pro, U590 and M581
- Seven mainstream cases for the DIY market: M340, S340, M220, M320, M330, S342 and M341
- Six options for entry-level, system integrator and business markets: S140, S190, S120, S133, S112 and S210
Arguably, the most attractive on show was the updated M580P-BA case – which measures 460mm x 285mm x 398mm and comes with 6 ARGB fans pre-installed as well as an FSP ZenFan. This case is likely to be around £180 in the UK and it could be interesting if FSP has picked up on the earlier M580 we reviewed back in February 2025 – including strengthening the build and including modular fan brackets. As with all FSP products, increased availability in the UK would be a bonus.
Lastly, FSP showed us a system that had produced to show off the idea of a Battery Back Up (BBU) that can step in ‘instantly’ if you suffer from a catastrophic drop in your mains power. FSP says that it has new/next-gen interruptible technology in products like the EnerXCube 450-M and 550-M. This is a solution for users who live in an area where frequent power outages and blackouts happen. It’s not immediately clear which parts of these new BBU units are covered by FSP’s patent application but you can get full details here.
KitGuru says: The promise from FSP’s new and improved products is huge. The reality will be uncovered in KitGuru Labs. One thing is for sure, we would like FSP products to be easier to buy.
