If the server segment of the FSP booth was focused on the future of AI infrastructure, the retail lineup demonstrated how this future is gradually penetrating everyday workstations, gaming PCs, and professional desktops.

In 2026, FSP offered not just a set of power supply units with different labels, but a clearly structured ecosystem where each series addresses its own range of tasks, and the technical solutions of older models eventually become the standard for younger ones. This is no longer "choosing by watts," but a conscious design of power supply with an eye on increasing loads, stability requirements, and noise levels.

MEGA Series — Ultimate Performance

The flagship MEGA series is based on the MEGA TI (Titanium) and MEGA GM (Gold) models. At Computex 2026, the leading MEGA TI model with a power of 1650 W was presented, which received 80 PLUS Titanium and Cybenetics Titanium certifications, confirming not only high efficiency (>94% across a wide range of loads) but also parameter stability in real operating conditions.

However, behind these figures are several key technical solutions.

Firstly, it's the Interleaved PFC (Power Factor Correction with interleaved channels) topology. Unlike classic single-phase PFC, this uses two parallel channels operating with a 180-degree phase shift. This significantly reduces input current ripple, improves the power factor even at partial load, and noticeably reduces the requirements for input filters and electrolytic capacitors. Combined with Infineon power MOSFETs and silicon carbide (SiC) diodes, this architecture provides high accuracy in regulating output voltages under sharp current surges—typical for modern graphics cards with dynamic overclocking.

Secondly, the patented FSP Micro Tolerance Load Control (MTLC) technology. This is an active compensation system for output voltage deviations that keeps it within ±0.5% on all main lines (12V, 5V, 3.3V). For comparison, the Intel ATX 3.1 specification allows deviations of up to ±5%. Such accuracy is especially important for systems with multiple high-power GPUs, where a drop on the 12-volt rail can cause driver resets or instability in neural network algorithms. MTLC is implemented not at the software compensation level, but at the hardware level—using a separate controller and precision voltage dividers with low temperature drift.

Thirdly, the MEGA series received Cybenetics A++ noise level certification. This is achieved not only due to high efficiency (minimal dissipated heat → quiet fan) but also due to thoughtful case aerodynamics and the use of fans with a hydrodynamic bearing and optimized impeller. In low and medium load modes, the fan either stops completely (semi-passive mode) or rotates at minimum speeds, making the unit virtually inaudible even in an open case.

In addition, all MEGA series boards are covered with conformal coating—the same protective coating that was previously found only in military and industrial electronics. In conditions of working with a powerful GPU, when the temperature inside the case can exceed 50–60 °C, and condensation or dust become real risk factors, this coating provides long-term reliability and corrosion protection, especially in regions with humid climates.

The MEGA lineup also includes MEGA PM 1350 W and MEGA GM 1000 W models, which inherit the same Interleaved PFC and MTLC architecture, but optimized for platinum and gold efficiency levels, respectively. All units are equipped with native 12V-2x6 connectors (ATX 3.1 / PCIe 5.1), support dynamic load monitoring, and are compatible with proprietary FSP Guardian software for real-time parameter control.

VITA Series

The VITA series represents the foundation on which the bulk of retail sales rests. These are balanced power supply units aimed at a wide range of users—from office systems to mid-range gaming PCs. However, the word "balanced" in this case does not mean "simplified."

The VITA lineup covers three efficiency levels:

• VITA PM (Platinum) — for systems requiring high efficiency and reduced heat dissipation, but where the budget does not allow for the MEGA series. The same LLC + SR topology (resonant converter with synchronous rectification) is used, but without Interleaved PFC, which provides savings while maintaining 80 PLUS Platinum.
• VITA GM (Gold) — the optimal choice for most mid-range builds. Fully modular design, 100% Japanese capacitors (450V, 105°C), protection against overheating, overvoltage, and short circuit. The fan with automatic speed control ensures low noise levels even under load.
• VITA BD (Bronze) — the budget segment, but with a fundamental difference from older solutions. Now, even here, DC-DC conversion is used for the 5V and 3.3V lines instead of outdated group stabilization. This ensures voltage stability during load imbalances (for example, when a graphics card consumes 300W, and the rest of the system consumes much less), which is critical for modern motherboards and SSDs.

All VITA models are in ATX form factor and fully comply with ATX 3.1 and PCIe 5.1 standards, guaranteeing compatibility with the latest graphics cards without adapters. For enthusiasts building systems without unnecessary wires, options with full modular cable management are available.

ADVAN Series

The ADVAN series occupies a niche between VITA and MEGA, adding an emphasis on silent operation and ease of assembly to good efficiency. These are units aimed at users who spend many hours at the computer, working with graphics or video.

ADVAN GM models are 80 PLUS Gold certified and optimized for low noise levels even at loads up to 80% of the nominal. This is achieved through the use of fans with an increased impeller diameter (135–140 mm) and a specially selected speed curve, as well as improved radiator geometry inside the unit, which allows for efficient heat dissipation at lower impeller rotation speeds.

In addition, ADVAN GM is equipped with an improved input voltage filtering system, making them a good choice for regions with unstable power grids. The design provides surge protection up to 4 kV and operation in a wide range of input voltages (100–240 V) without manual switching.

Like all new FSP models, ADVAN supports 12V-2x6 and has a fully modular cable system with flat wires for easy routing in cases with limited space.

VIC Series

The VIC series replaces outdated lines like PNR and demonstrates that even in the affordable segment, modern architecture can be offered. In 2026, FSP expanded VIC to three levels.

• VIC PM (Platinum) — a solution for the budget series: 80 PLUS Platinum, which was previously rare even in the mid-price range. This model is aimed at office PCs and thin clients operating 24/7, where every percentage of efficiency saves energy and reduces heating.
• VIC GM2 (Gold) — an updated version with improved output voltage regulation and reduced ripple levels (< 30 mV on the 12V line), which meets the requirements even for sensitive peripherals.
• VIC BD (Bronze) — a basic model, but with a mandatory DC-DC converter and 80 PLUS Bronze, making it more stable and durable compared to outdated group topologies.

All VIC units have a non-modular design (except for certain variants), which reduces cost, but they use Japanese capacitors in the primary circuit and Taiwanese ones in the secondary, ensuring a stated service life of at least 100,000 hours at 25°C.

General Technological Trends in the 2026 Retail Lineup

A unifying element for all four series is the complete transition to ATX 3.1 and PCIe 5.1 standards. This means not only the presence of the new 12-pin connector but also support for power excursions—the ability of the unit to momentarily deliver up to 200% of its nominal power for 100 µs, which corresponds to the behavior of modern graphics accelerators during sharp changes in frame rate or the launch of heavy computational tasks.

In addition, the entire FSP retail lineup is now equipped with a self-diagnosis system at startup—the unit checks all main components (PFC, resonant stage, output rectifiers) and only after successfully passing the test does it send a Power Good signal to the motherboard. This reduces the risk of component damage in case of abnormal situations.

It is also worth noting the unification of cable sets within the series. All modular models use the same pinout for connectors on the unit side, allowing the power supply to be replaced within the same series without re-routing cables in the case—a convenient solution for upgrades.
