Slim Specs Table

ATX 3.1 and PCIe 5.1 Compatibility

This PSU meets the ATX 3.1 specification. It handles power excursions common with modern graphics cards. The unit includes a native 12-pin PCIe connector. It also provides standard 6+2 pin PCIe cables. This ensures broad compatibility with current and next-generation components. You can connect high-end GPUs directly without adapters.

Quiet Active Cooling

A 12 cm fan uses Rifle bearing technology. This provides long life and low noise. The cooling type is active, but noise is rated at just 31.6 dB. So, the unit stays cool under load without intrusive sound. It is ideal for quiet office or gaming builds. The fan curve is tuned for minimal noise at typical loads.

High-Efficiency Power Delivery

The unit achieves 80 PLUS Gold certification. Efficiency reaches 90.6% at typical load. Active Power Factor Correction (PFC) ensures clean power draw. This reduces wasted energy and heat. The single +12V rail provides 83.4 A. This supports power-hungry CPUs and GPUs reliably. Hold time is 17.82 ms, aiding system stability during brief outages.

Comprehensive Protection Features

Your components are guarded by multiple protections. These include Over Current (OCP), Over Power (OPP), and Over Voltage (OVP). It also has Overheating (OTP), Short Circuit (SCP), and Surge & Inrush Protection (SIP). Under Voltage (UVP) is included as well. This suite ensures safe operation under various conditions. The 100,000-hour MTBF indicates long-term reliability.

Connectivity and Cabling

The PSU uses a non-modular design. Key cables are fixed to the unit. It includes a 20+4 pin ATX motherboard connector (55 cm). CPU power is 4+4 pin (60 cm). You get three 6+2 pin PCIe connectors (60 cm) and one 12-pin PCIe cable. SATA power cables are provided in multiple lengths (500–950 mm). One Molex peripheral connector is included (800 mm). Note: Cable ties and screws are included for installation.
