SFX-L 850 W Platinum PSU

The ASUS ROG Loki SFX-L delivers 850 W of continuous power in a 125 mm long fully modular chassis. It targets compact gaming builds that need ATX 3.0 compliance and a native 16-pin PCIe Gen 5 connector for modern graphics cards. The 80 PLUS Platinum rating guarantees up to 92 % efficiency across typical loads.

Lambda A noise and axial-tech cooling

A 120 mm PWM ARGB fan keeps acoustics below 25 dB at low to medium load, earning Lambda A certification. ROG heatsinks cover critical components to lower internal temperatures and extend unit lifespan. The fan curve stays quiet during everyday workloads while maintaining thermal headroom for sustained output.

Compact footprint with ATX adapter included

The 125 x 125 x 63.5 mm form factor fits SFX-L bays and, with the bundled bracket, standard ATX cut-outs. Full modular cabling includes two CPU 4+4-pin leads, three PCIe 8-pin leads, one PCIe Gen 5 16-pin lead, six SATA and four peripheral connectors. Aura Sync RGB integration synchronises lighting with compatible motherboards.

Perguntas sobre este artigo

Will this 125 mm long unit fit in a standard SFX-L case?

The housing is 125 mm deep and an ATX-to-SFX bracket is included, so it matches the SFX-L form factor used by most current small-form-factor cases.

Can the single 16-pin cable deliver 600 W to a PCIe 5.0 graphics card without adapters?

Yes, the bundled 16-pin cable is rated for up to 600 W and plugs directly into the PSU, meeting ATX 3.0 requirements for Gen 5 cards.

How loud is the 120 mm fan under typical gaming loads?

Lambda A certification confirms noise stays below 25 dB, and the PWM fan stops completely at low load for silent idle operation.
