This article covers ASUS ROG Loki SFX-L 1000W プラチナ電源.

Overview

The ASUS ROG Loki SFX-L 1000W Platinum is a compact yet powerful power supply unit capable of driving high-end PCs with ease. It holds both 80 PLUS Platinum and Cybenetics Platinum certifications, achieving up to 92% efficiency. The fully modular design complies with the latest ATX 3.1 and PCIe 5.1 standards, and the included 12V-2x6 cable can deliver up to 600W to next-generation graphics cards. Equipped with a 120mm Axial-tech PWM fan, the PSU balances silent operation with effective cooling. A 0dB fan button allows the fan to stop completely under low loads. ROG's proprietary heatsink covers key components, reducing temperatures and improving long-term reliability. Aura Sync compatible ARGB lighting unifies the look of your gaming build. This unit adopts the SFX-L form factor (125x125x63.5mm), making it ideal for users aiming to build a high-end system in a compact case. Backed by a 10-year warranty, the ROG Loki SFX-L 1000W Platinum is positioned as a top-tier small-form-factor PSU, offering premium features that few competitors match.

Compatibility Guide

  • Form Factor: SFX-L (125×125×63.5mm) – an included ATX bracket allows installation in standard ATX cases as well. - Electrical Standards: Fully compliant with ATX 3.1 and PCIe 5.1. The 12V-2x6 (12+4 pin) cable directly connects to GeForce RTX 40 series and other PCIe 5.0 GPUs. - Cable Configuration: Fully modular – you only attach the cables you need. Includes 1x 12V-2x6, 2x EPS12V (CPU), 6x PCIe 6+2 pin, 12x SATA, and 4x Molex cables. - Case Compatibility: Requires an SFX-L compatible case. Many ITX enclosures (e.g., Cooler Master NR200, Lian Li Q58) and compact mid-towers work. Always check your case's PSU clearance before purchasing.

Product Info

Launched in January 2023, the ASUS ROG Loki SFX-L 1000W Platinum sits at the pinnacle of compact high-end power supplies. With dual Platinum certifications, it delivers top-tier efficiency and build quality. - Efficiency Certificates: 80 PLUS Platinum / Cybenetics Platinum - Fan: 120mm Axial-tech PWM fan with 0dB mode - Protection Circuitry: OPP/OVP/UVP/SCP/OCP/OTP - Warranty: 10 years - Price: Approximately ¥57,740 on (tax included)

Best Use Cases

  • Small-Form-Factor Gaming Builders: Users who want to pair a compact case (e.g., ITX) with a top-tier GPU like RTX 4090. The 1000W headroom and native 12V-2x6 cable provide clean, stable power delivery. - Silence-Seeking Enthusiasts: The 0dB mode ensures total silence at idle or light load. The Axial-tech fan remains quiet even under heavy load, and the ROG heatsink helps keep fan speeds low. - Long-Term PC Investors: 10-year warranty, Japanese capacitors, and rigorous quality testing mean this PSU can outlast multiple builds. A strong choice for users who value durability over price. - Not for budget-constrained users: If cost per watt is your main metric, there are cheaper 1000W units (e.g., from Corsair RMx or EVGA). Also, if you use a large ATX case, a standard ATX PSU often offers better value and cable length.

Things to Consider

  • Case compatibility: SFX-L is longer than standard SFX. Many ITX cases support it, but always double-check your case specs. The included ATX bracket works, but cable lengths are optimized for compact builds – large towers may need extensions. - 12V-2x6 connector handling: Ensure the connector is fully seated into your GPU to avoid overheating. Listen for a click and verify with a visual check. - Overkill scenarios: For mid-range GPUs (RTX 4060, RX 7600) with a modest CPU, 1000W is excessive. A 650W unit would suffice. However, buying ahead for future upgrades is a valid strategy. - Competitors: Corsair SF1000L and SilverStone SX1000 also offer 1000W SFX-L. The ROG Loki distinguishes itself with ARGB, Aura Sync, and the 0dB button. If these extras aren't important, the alternatives may offer better value. ## FAQ
    Q: What's the difference between SFX-L and SFX? A: SFX-L is about 30mm deeper (125mm vs. 100mm), allowing for a larger fan and more circuitry, enabling higher wattage. The mounting screw pattern is the same, but the extra length may interfere with front panel connectors or drive cages in some cases. Always check your case's PSU clearance. Q: Is ATX 3.1 backwards compatible with ATX 3.0 GPUs? A: Yes. The new 12V-2x6 connector is electrically identical to the older 12VHPWR. You can use this PSU with any PCIe 5.0 GPU without issues. The updated connector offers improved mechanical retention. Q: Should I buy this PSU for a mid-range build? A: It's technically possible, but overkill unless you plan significant future upgrades. A 650-750W Platinum unit would be more cost-effective for a mid-range PC. The ROG Loki excels in high-end small-form-factor builds where every watt and every feature matters.
