In ATX power supply OEM projects, selecting the right specifications is the core to ensuring product compatibility, performance stability, and market competitiveness. Whether it is for home PCs, gaming systems, or industrial control equipment, every specification detail of the OEM ATX power supply affects the final user experience and the reputation of the cooperative brand. For partners seeking personalized solutions, the ability to meet ATX power supply customized needs is equally critical. This article will systematically sort out the key specifications for ATX power supply OEM projects and explain how Yijian, as a professional manufacturer, meets these requirements to support project success.
Compliance with ATX Industry Standards
Adhering to industry standards is the basic premise of OEM ATX power supply development, as it ensures compatibility with mainstream motherboards and hardware.
Compatibility with ATX Version Standards
The ATX standard is continuously updated, and the latest ATX 3.0 specification has become a key requirement for high-performance OEM ATX power supply. This standard supports the 12VHPWR 16-pin interface, which can provide up to 600W of power for PCIe 5.0 graphics cards, and can withstand 200% peak power for 100 microseconds to adapt to sudden load surges of high-end hardware. For example, when cooperating with a gaming PC brand on an OEM project, Yijian’s OEM ATX power supply fully complies with ATX 3.0, ensuring seamless compatibility with NVIDIA RTX 40 series and AMD RX 7000 series graphics cards. For partners targeting entry-level markets, Yijian also provides OEM ATX power supply that meets ATX 2.52 and other classic standards, balancing cost and compatibility.
Compliance with Physical Dimension Specifications
The physical size of ATX power supply is strictly regulated by industry standards (e.g., standard ATX is 150mm × 86mm × 140mm), which directly affects whether it can be installed in standard PC cases. In OEM ATX power supply projects, any deviation in size may lead to assembly failures and increase rework costs. Yijian uses high-precision mold processing and automated assembly lines to control the dimensional error of each OEM ATX power supply within ±0.5mm. For ATX power supply customized needs such as small-form-factor (SFF) PC projects, Yijian’s R&D team can adjust the size (e.g., designing 120mm × 86mm × 100mm mini-ATX power supplies) while ensuring compatibility with case mounting holes, meeting the personalized installation requirements of partners.
Core Technical Specifications for OEM ATX power supply
Technical parameters determine the performance and stability of OEM ATX power supply, which are the focus of partners’ attention in OEM projects.
Power and Load Capacity Matching
The power rating of OEM ATX power supply must match the hardware configuration of the target product. For example, entry-level office PCs only need 300W-400W OEM ATX power supply, while mid-to-high-end gaming PCs require 600W-800W, and workstations may need 1000W or more. Yijian not only provides a full range of power options (300W-1600W) but also ensures that each OEM ATX power supply has a 10%-20% power reserve. This reserve prevents overload caused by sudden hardware power consumption increases (e.g., CPU overclocking) and extends the service life of the power supply. In ATX power supply customized projects, Yijian can also adjust the load distribution (e.g., increasing 12V output current for high-power graphics cards) according to partners’ hardware parameters.
Energy Efficiency Certification Level
Energy efficiency is a key specification for OEM ATX power supply, as it affects energy consumption, heat generation, and user operating costs. The 80 PLUS certification system is widely recognized globally, with levels ranging from Bronze to Titanium. A qualified OEM ATX power supply should at least meet 80 PLUS Bronze (82% efficiency at 20% load, 85% at 50%, 82% at 100%), while high-end projects often require Gold or above. Yijian’s OEM ATX power supply all pass 80 PLUS Gold or Platinum certification; for example, its 650W OEM ATX power supply achieves 90% efficiency at 50% load, reducing heat output by 15% compared to Bronze-level products. This not only meets the energy-saving requirements of global markets (e.g., EU ERP Directive) but also enhances the product’s market competitiveness for partners.
Voltage Stability and Ripple Control
Voltage stability and ripple are critical to protecting hardware and ensuring stable operation. The OEM ATX power supply must maintain output voltage deviation within ±2% (e.g., 12V output ranges from 11.76V to 12.24V) and ripple below 50mVp-p. Excessive voltage fluctuations or ripple can cause blue screens, crashes, or even damage to motherboards and hard drives. Yijian implements strict voltage and ripple control in the production of OEM ATX power supply: it uses high-precision voltage regulators and low-ESR capacitors, and conducts 100% ripple testing for each unit before delivery. For ATX power supply customized projects with high stability requirements (e.g., industrial control PCs), Yijian further optimizes the circuit design to reduce ripple to below 30mVp-p.
Customization Capabilities for ATX power supply customized Needs
In OEM projects, partners often have personalized demands, so the ATX power supply customized capabilities of manufacturers directly determine project flexibility.
Interface and Cable Customization
Different PC configurations require different interface combinations and cable lengths. For example, gaming PCs may need multiple PCIe 6+2-pin interfaces for graphics cards, while industrial PCs require 24-pin ATX interfaces with anti-loose designs. Yijian supports full interface customization for ATX power supply customized projects: partners can choose the number and type of interfaces (e.g., SATA, Molex, PCIe) and cable lengths (e.g., 600mm for large cases, 300mm for SFF cases). It also provides modular cable designs—users can install only the needed cables to reduce internal clutter and improve heat dissipation. Yijian’s 20+ appearance design patents include innovative cable management solutions, making its ATX power supply customized services more competitive.
Appearance and Structural Customization
Branding and case matching often require appearance customization of OEM ATX power supply. Yijian offers ATX power supply customized options such as shell color (black, white, or custom Pantone colors), logo printing (silk-screen or laser engraving), and fan cover designs. For example, when cooperating with a white-themed PC brand, Yijian developed a white-shell OEM ATX power supply with a transparent fan cover, matching the brand’s aesthetic. In terms of structure, Yijian can also add features like dust filters or shock-absorbing pads for ATX power supply customized needs in harsh environments (e.g., industrial workshops), enhancing product durability.
Functional Customization
Special scenarios require functional customization of OEM ATX power supply. For silent PC projects, Yijian can equip the power supply with a 140mm hydraulic bearing fan and add a zero-noise mode (the fan stops at low loads). For smart PC projects, it integrates RS485 communication interfaces to support remote monitoring of voltage, current, and temperature.
