Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, is its output. This indicates the maximum number of Watts the power supply can continuously deliver to the computer's components. It's a good idea to use a web calculator to work out the optimal output based on your chosen components.
Performance for compact builds
The power supply provides a continuous and stable 1000W output, easily covering the energy demands of gaming and workstations equipped with modern multi-core processors and high-consumption graphics cards. Its design is specifically optimised for Small Form Factor. Thanks to its compact SFX format, it fits into even very small computer cases. Full compatibility with the ATX 3.1 standard and support for the PCIe 5.1 bus prepares your build for current and future generation hardware. The ATX 3.1 standard places high demands on a power supply's ability to handle extreme power spikes. This PSU can withstand short-term fluctuations in consumption, which are typical for high-performance graphics cards, thereby actively contributing to the stability of the entire system even under maximum load.
Quiet and efficient cooling system
Heat is dissipated by a fan with a fluid dynamic bearing, which operates in a semi-passive Zero RPM mode. At low and medium loads, such as working with documents or watching videos, the fan stops completely and the power supply runs absolutely silently. It only activates when the temperature of the internal components reaches a preset level, maintaining optimal operating conditions while keeping noise low.
80 PLUS Platinum certification
The high electrical energy conversion efficiency, confirmed by the 80 PLUS Platinum certification, reduces the generation of waste heat and limits electricity consumption. Under typical load, the power supply converts over 92% of the mains energy into usable power for your components. Lower heat losses mean less demand for active cooling, which leads to quieter operation and extends the lifespan not only of the power supply itself but also of the other components in the case.
Reliability and durable construction
The internal construction exclusively uses Japanese electrolytic capacitors rated for an operating temperature of up to 105°C. These components are fundamental for consistent power delivery and long-term reliability. They maintain precise voltage regulation and filtering even under prolonged load in environments with an ambient temperature of up to 50°C, thus protecting sensitive computer components from power instability.
Connectivity for graphics cards
Included in the package is a native 16-pin 12VHPWR cable, also known as 12V-2x6, which is used for directly powering NVIDIA GeForce RTX 40 series and future graphics cards. The presence of this connector eliminates the need for bulky and potentially unreliable adapters. A direct connection simplifies installation, improves the build's appearance and supplies the graphics card with clean and stable power. All cables are fully detachable, which simplifies the building process and cable management in the limited space of SFF cases. It uses Type-5 Micro-Fit connectors, which are compact and reliable. You only connect the essential cables and leave the rest in the box. The result is more effective airflow, which is crucial for cooling all components in small cases.

80 Plus certification on the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. This provides users with a simple and clear way to compare different models. On the European market (where a 230V voltage is used), there are six levels of 80 Plus certification with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
