ASUS ROG Loki SFX-L 1000W Platinum Review

If you're searching for the ASUS ROG Loki SFX-L 1000W Platinum, or just looking for a solid 1000W 80 PLUS Platinum PSU in a SFX-L form factor, here's the full rundown on specs, price, and how it stacks up.

Short answer: the ROG Loki SFX-L 1000W Platinum is a fully modular 1000W unit built to the ATX 3.0 spec, and we'd recommend it if you want Platinum-tier efficiency at this wattage without chasing a flagship price tag.

Efficiency and Build Quality

The ROG Loki SFX-L 1000W Platinum carries an 80 PLUS Platinum certification and Cybenetics Platinum efficiency / A noise, built on a CWT platform. Its 92mm Axial-tech fan, 0dB mode keeps noise down, with Zero-RPM fan-stop under light loads.

Connectors and Cabling

You get 1x 24-pin ATX, 1x EPS 4+4, 1x 12V-2x6 (600W), 4x PCIe 6+2-pin, 6x SATA, 2x Molex. Cable lengths run 24-pin 550mm, EPS 600mm, 12V-2x6 600mm, PCIe 600mm, SATA 700mm, and the cables are standard black ribbon/flat, not sleeved. It's rated for a 17ms hold-up time and backed by OCP, OVP, OPP, SCP, OTP, UVP protection circuitry.

Comparison to Alternatives

Compared to the ASUS ROG Loki SFX-L 850W Platinum, the ROG Loki SFX-L 1000W Platinum lands in the same efficiency tier at a different capacity, so the choice mostly comes down to how much wattage headroom you actually need. It's also worth cross-shopping against the Corsair SF1000L if you're weighing Platinum-tier options in this wattage class; both land in a similar price bracket, so the deciding factor usually comes down to form factor, cable sleeving, and warranty length.
