PCIe Connector Type: 16-pin PCIe
The inclusion of a 16-pin PCIe connector allows direct connection to modern graphics cards that require this specific interface. This cable supports higher power delivery for next-generation GPUs, eliminating the need for multiple adapters. You should check if your graphics card utilizes this native connector, as it simplifies cable management and ensures optimal power delivery for high-performance video cards.
Design and build quality
The ASUS ROG Loki SFX-L 1000W Platinum PSU measures 4.9 by 2.5 by 4.9 inches and weighs 4 pounds. This compact SFX form factor allows installation in small form factor cases where standard ATX units will not fit. The listing states that ROG heatsinks cover critical components. This design choice aims to lower operating temperatures, which can extend the lifespan of internal parts and help reduce fan noise during operation.
According to the listing, the unit features a 120mm Axial-tech fan with PWM control. This larger fan size for an SFX unit helps maintain thermals while keeping noise levels low. The finish includes Aura Sync compatibility, allowing the unit to synchronize lighting effects with other gaming components. This adds a visual element to builds where the power supply is visible through a side panel.
The unit carries an 80 PLUS Platinum certification. This rating indicates high efficiency, which translates to less wasted energy as heat. Higher efficiency also contributes to lower internal temperatures and improved reliability. The ATX 3.0 compliance means the unit includes a 16-pin PCIe cable. This cable can deliver up to 600W of power directly to modern PCIe Gen 5.0 graphics cards. This design ensures you can connect high-end GPUs without needing multiple adapters.
Setup and everyday use
Installation begins with fitting the unit into your case. The SFX-L form factor measures 4.9 by 2.5 by 4.9 inches. This compact size allows it to fit in small chassis where standard ATX units do not. You secure the unit using standard mounting points for SFX power supplies.
Cabling involves connecting the 16-pin PCIe connector. The listing states the unit is ATX 3.0 compatible. It bundles a 16-pin cable designed for PCIe Gen 5.0 graphics cards. This cable can deliver up to 600W of power directly to your GPU. You connect this to compatible modern graphics cards. Other standard connectors attach to your motherboard and drives as usual.
During daily use, the 120mm fan manages thermals. The listing notes PWM control for low noise. This fan size is larger than typical SFX fans, which helps keep temperatures down. The ROG heatsinks cover critical components to lower operating temperatures. This design aims for reduced noise and a longer lifespan.
Efficiency is rated at 80 PLUS Platinum. This means up to 92% efficiency. Higher efficiency results in less waste heat and potentially lower noise levels. The unit supports Aura Sync. You can synchronize lighting effects across your gaming setup. This feature requires compatible ASUS hardware and software. The 1000W output provides headroom for high-end components. This ensures stable performance under heavy loads without straining the unit.
Check Compatibility Before Buying
Owning this unit requires verifying your case supports the SFX-L form factor. The listing confirms a width of 4.9 inches and a height of 2.5 inches. You must ensure your chassis has the correct mounting holes for this compact size. Since it is ATX 3.0 compatible, you should use the bundled 16-pin PCIe cable for Gen 5.0 graphics cards. This avoids using adapters that might not handle the 600W power delivery safely. The 120mm fan provides quiet operation, but you should keep intake vents clear to maintain the low temperatures listed. Regular dust removal from the fan blades helps sustain the 80 PLUS Platinum efficiency. Compared to larger ATX units, this fits in tight builds where space is limited. Check your motherboard headers for Aura Sync if you want synchronized lighting. Ensure your power cables are routed properly to avoid strain on the connectors.
Check before you buy
- Verify your case supports the 2.5-inch height SFX-L form factor
- Ensure your GPU supports the native 16-pin PCIe connector
- Confirm your motherboard has Aura Sync headers for lighting sync
- Check that your case has adequate airflow for the 120mm fan
