The SFX power supply for modern compact builds
Building a small form factor (SFF) or mini-ITX PC in South Africa demands a PC power supply that delivers significant power without occupying excessive chassis space. This Dagger Pro unit answers this need directly. It is an SFX power supply engineered to meet the ATX12V 3.0 and PCIe 5.0 standards, ensuring forward compatibility with next-generation components. A dedicated SFX power supply solution, it fits into the tightest enclosures, yet comes with an ATX adaptor bracket for standard cases. An ideal choice for builders prioritising both footprint and performance. A robust PC power supply is essential.
ATX 3.0 & PCIe 5.0 readiness for next-gen GPUs
Modern high-end graphics processing units require a stable and robust PC power supply. This PC power supply model features native ATX12V 3.0 compliance, supporting temporary power excursions up to 200% of its rated 850W output. A dedicated 16-pin PCIe 5.0 connector handles GPUs like the RTX 40 Series directly, eliminating bulky adaptors. This PC power supply ensures clean power delivery for peak performance during demanding gaming sessions or rendering tasks. Reliability is paramount.
Efficiency & quiet operation in a small form factor
An SFX power supply must balance performance with thermal management and acoustics, especially in confined builds. A quality SFX power supply also runs cool. This power supply unit carries an 80 PLUS Gold certification, achieving 90% or higher efficiency at typical load. Less waste heat generated translates to a cooler system. A 92mm ball bearing fan ensures active cooling when needed. The semi-fanless design keeps this desktop PSU silent until loads exceed approximately 20%. Your PC power supply keeps your system quiet.
Build quality & longevity for South African conditions
This PC power supply is built with Japanese electrolytic capacitors. This component choice is critical for stability and extending the operational lifespan of this PC power supply. The Dagger Pro is designed for consistent performance, even in challenging environments like fluctuating power stability common in some Jozi builds. Protection mechanisms (OCP, OVP, SCP, OPP, OTP) are integrated to safeguard your expensive components. A 10-year warranty backs this commitment to durability. Long-term peace of mind.
Simplified installation with full modularity
Compact PC builds are often challenging regarding cable management. This SFX power supply is fully modular, meaning only necessary cables are connected. An efficient PC power supply minimises clutter. Flat ribbon cables enhance flexibility, allowing tighter bends and improved airflow within the chassis. The included ATX adaptor bracket means this power SFF can also be used in standard ATX cases, offering versatile deployment options. Installation becomes simpler for this SFX power supply.
