Import 900w Apfc Version Atx Power Supply — Buy in Bulk from Supplier in China

The Kineagle 900W APFC version ATX power supply is a desktop PSU rated for Intel Core i3/i5/i7 and AMD Phenom/Athlon platforms, built on a dual-switch forward converter topology with active power factor correction. The unit claims 80 Plus standard compliance with efficiency above 80%, measured at 115V AC/60Hz or 230V/60Hz input. A mean time between failures (MTBF) of 100,000 hours and output rise time of 0.2-20ms position it within standard reliability expectations for mass-market PC power supplies, while the PG (power good) signal rise time under 1ms indicates compatibility with modern motherboard soft-start requirements.

The dual-switch forward converter design, rather than more common single-switch forward or half-bridge LLC resonant topologies, spreads switching stress across two MOSFETs and allows higher power handling with reduced voltage stress on primary semiconductors. This architecture is typically paired with a CCM (continuous conduction mode) boost PFC stage for APFC, yielding power factor correction above 0.9 at full load. The 150 x 140 x 86mm form factor conforms to standard ATX12V dimensions, ensuring mechanical compatibility with mid-tower and full-tower chassis. Typical output rail configuration for this class includes +3.3V, +5V, +12V (often split across multiple 12V rails in 900W designs), and -12V, +5VSB standby.

Target buyers include system integrators, white-box PC assemblers, and gaming peripheral distributors who require volume supply of compliant ATX units without boutique pricing. The 80 Plus minimum efficiency threshold, while entry-level by current standards, satisfies corporate procurement specifications and basic regulatory requirements in most export markets. For import planning, confirm with Kineagle whether the unit carries 80 Plus certification with posted test data on the 80 Plus organisation website, or whether the 80%+ claim is based on internal testing only. Also verify the exact +12V rail amperage distribution, as 900W units vary between single-rail and multi-rail 12V designs with significant implications for high-end GPU compatibility.

Kineagle operates from Unit B, Jinlong Industrial Zone, Third Village Committee, Shenzhen 523651, Guangdong, China, situating it within the Pearl River Delta electronics manufacturing cluster. The supplier holds an imported tier and harbour trust classification, with zero recorded response rate and no average response hours in the dataset. This profile pattern suggests a registered entity with limited active engagement on the platform, so buyers should plan for extended communication cycles and consider direct contact methods beyond platform messaging.

The available profile does not disclose factory size, R&D staff count, annual turnover, or key accounts, nor does it list specific quality certifications (ISO 9001, IECQ QC 080000 for hazardous substance management). The product description omits safety agency approvals (UL, TUV, CCC, CE LVD) that are critical for power supply exports to regulated markets. Buyers should request business licence verification, factory audit reports, and evidence of UL or TUV-CB testing before committing to volume orders, as uncertified PSU sales can trigger customs rejection and liability exposure in destination countries.
