With the rise of high performance hardware like PCIe 5.0 graphics cards and overclockable CPUs, ATX 3.0 has become the mandatory standard for modern power supplies. For OEM orders targeting gaming PCs, workstations, or professional equipment, an 850W power supply that fully supports ATX 3.0 (and its upgraded ATX 3.1 version) is a core requirement. Selecting such products requires balancing technical compliance, customization flexibility, and manufacturing reliability. As a professional atx 3.1 power supply Supplier and OEM 850W power supply manufacturer, Yijian has developed mature solutions that meet global OEM needs. This article details the key selection criteria and why Yijian stands out in this field.
Core Technical Specifications for ATX 3.0/3.1 Compliant OEM 850W power supply
To qualify for OEM orders, an 850W power supply must first meet the rigid technical requirements of ATX 3.0 and its enhanced ATX 3.1 standard. These specifications directly determine compatibility with high end hardware.
12VHPWR Interface and Peak Power Handling
ATX 3.0 and 3.1 both mandate a 12VHPWR 16 pin interface to support PCIe 5.0 graphics cards, but ATX 3.1 raises the bar for power delivery. A qualified OEM 850W power supply should provide up to 600W through this interface (with adjustable 450W 300W 150W modes) and withstand 200% peak power for 100 microseconds. This ensures stability when GPUs like NVIDIA RTX 5080 or AMD RX 8000 series experience sudden load spikes. Yijian’s OEM 850W power supply exceeds these requirements: its 12VHPWR interface uses reinforced H++ terminals to prevent overheating during high load operation, and the peak power handling capability reaches 220% for 150 microseconds, providing extra safety margin for OEM clients’ high performance hardware configurations.
Single 12V Rail and Voltage Stability
ATX 3.0/3.1 prioritize stable 12V power delivery, as modern CPUs and GPUs rely entirely on this rail. An 850W power supply should adopt a single 12V rail design with at least 70.8A current output. More importantly, voltage deviation must be controlled within ±1% (stricter than ATX 2.52’s ±5% standard) to avoid hardware damage. Yijian achieves this through DC DC digital independent 稳压 design and collaboration with NXP on customized control chips. Its OEM 850W power supply maintains 12V output deviation below 0.8%, with ripple and noise under 30mVp p—far superior to industry averages. This level of stability is critical for OEM orders targeting gaming or professional workstations where hardware longevity is key.
Energy Efficiency and Wide Voltage Adaptation
Energy efficiency directly impacts the market competitiveness of OEM products. ATX 3.1 recommends 80 PLUS Gold certification or higher, meaning the power supply achieves at least 90% efficiency at 50% load. Yijian’s OEM 850W power supply exceeds this with 80 PLUS Gold certification, reaching 92.6% efficiency at 50% load and 90.1% at full load. This reduces energy consumption and heat generation for end users. Additionally, global OEM orders require wide voltage support: Yijian’s unit covers 90~264V AC, adapting to unstable grids in regions like Southeast Asia and Brazil. It also operates reliably at 5000m altitude and 35℃ ambient temperature, making it suitable for diverse geographic markets.
OEM Customization Capabilities for 850W Power Supply Orders
OEM clients often have personalized needs tied to their brand and product positioning. A capable atx 3.1 power supply Supplier must offer flexible customization to align with these requirements.
Interface and Cable Customization
Different OEM products demand specific interface configurations. For example, gaming PC clients may need multiple PCIe 6+2 pin connectors, while small form factor (SFF) desktop clients prefer compact cable designs. Yijian provides full interface customization for its OEM 850W power supply: clients can choose the number of SATA (up to 8), PCIe 6+2 pin (up to 4), and EPS 4+4 pin (1 or 2) interfaces. It also offers modular or non modular options—modular designs use braided or snake skin cables (700mm CPU cables 600mm PCIe cables) for easier case management, while non modular versions reduce costs for budget friendly OEM lines. As an experienced atx 3.1 power supply Supplier, Yijian can even adjust cable colors to match clients’ brand aesthetics (e.g., white cables for minimalist PC lines).
Appearance and Structural Adjustments
Branding and case compatibility drive appearance customization needs. Yijian supports shell color customization (black white or custom Pantone shades), laser etched logos (minimum order 300 units), and fan cover designs (transparent or branded). For structural flexibility, its OEM 850W power supply maintains standard ATX dimensions (150mm×86mm×140mm) for universal compatibility, but can be modified to 130mm depth for SFF cases with minimal efficiency loss. Yijian’s 20+ appearance design patents enable these adjustments without compromising performance—a key advantage over competitors with rigid designs.
Parameter Tuning for Specific Scenarios
OEM clients in different industries need tailored performance parameters. For example, industrial PC clients may prioritize low noise over peak efficiency, while gaming clients want aggressive fan curves for cooling. Yijian’s R&D team (14 dedicated engineers) can tune parameters like fan speed thresholds (zero noise mode at <30% load) and overcurrent protection levels for the OEM 850W power supply. For a Southeast Asian client targeting cybercafés, Yijian modified the power supply to operate silently at 50% load and added surge protection for unstable local grids—customizations that helped the client capture 20% market share in the region.
