It features ROG Heatsinks for lower temperatures and extended 0dB operation, and a dual ball bearing fan for a 2x longer lifespan. The 0dB Technology allows the fan to shut off completely at loads of 40% or below, contributing to quiet operation. It boasts an 80 PLUS Titanium certification for high efficiency and uses low-ESR Japanese capacitors for reliability. The PSU is ATX 3.0 compatible, featuring a 16-pin PCIe cable for up to 600W of power to PCIe Gen 5.0 graphics cards. The Loki also includes an ARGB-illuminated fan with Aura Sync compatibility for customizable lighting. This PSU comes with a 10-year warranty for peace of mind.
This guide is for PC builders looking for a high-performance, compact power supply unit (PSU) for Small Form Factor (SFF) builds. The ASUS ROG Loki 1200W Titanium PSU offers quiet operation, high efficiency, and supports the latest hardware, including PCIe Gen 5.0 graphics cards. While the SFX-L form factor provides more power compared to SFX PSUs, it is crucial to ensure it fits your case before purchase.

Extended Product Information
FAQs
What is the SFX-L form factor?
SFX-L is a power supply form factor that's slightly larger than standard SFX, allowing for higher wattage and better cooling within a compact design. It's ideal for small form factor (SFF) builds.
What is 80 PLUS Titanium certification?
80 PLUS Titanium is a certification that indicates a high level of power efficiency. Titanium-certified PSUs must achieve at least 90% efficiency at 50% load, reducing energy waste and heat.
Does this PSU support PCIe Gen 5.0 GPUs?
Yes, the ROG Loki 1200W Titanium PSU includes a 16-pin PCIe cable capable of delivering up to 600W of power, making it compatible with the latest PCIe Gen 5.0 graphics cards.
How do I control the ARGB lighting?
You can control the ARGB lighting using ASUS Aura Sync software. Connect the ARGB cable from the PSU to a compatible ASUS or ROG motherboard.
What is the 0dB technology?
0dB technology means the fan stops spinning when the PSU load is 40% or below, providing silent operation during low-power tasks like browsing or watching videos.
What is the warranty period?
The ROG Loki 1200W Titanium PSU comes with a 10-year warranty.
What kind of cables are included?
The PSU includes AC, CPU, PCIe, Peripheral (Molex), and SATA cables which are fully modular to allow for better cable management.
Troubleshooting
PC won't power on.
Check the power cord connection, ensure the power switch on the PSU is turned on, and verify the wall outlet is working. Also, inspect all power cable connections inside the case.
PC powers on but won't boot.
Check all component connections (CPU, GPU, RAM, etc.). Reseat the RAM modules and the graphics card. Make sure the 24-pin ATX and 8-pin (or 4+4 pin) EPS connectors are securely plugged into the motherboard.
Fan is noisy.
Ensure the fan isn't obstructed by any cables. If the noise persists, it could indicate a fan issue. Monitor the PSU temperature to check the effectiveness of the cooling. Check if the PSU is overloaded.
System crashes or restarts under load.
This could indicate a power delivery issue. Verify that the PSU has enough wattage for all components. Check for any overclocking issues. Ensure all power cables are securely connected. Test with different components to isolate the problem (e.g., test with a different GPU).
ARGB lighting doesn't work.
Make sure the ARGB cable is connected to a compatible ASUS/ROG motherboard. Install the ASUS Aura Sync software to control the lighting effects. Check for any software conflicts.
Pros and Cons
Pros

Supports the latest ATX 3.1 and PCIe Gen 5.0 standards.
Features ARGB lighting with Aura Sync for customization.
Comes with a 10-year warranty.
Cons
SFX-L form factor may not be compatible with all SFF cases; requires careful measurement.
Higher cost compared to standard ATX power supplies.
May generate more heat than an ATX PSU due to size constraints (even though the cooling solution is quite effective).
ARGB lighting requires a compatible ASUS/ROG motherboard for full functionality.
Limited availability compared to some other PSU form factors.
Setup, Compatibility & Care
Installation: Ensure your SFF case supports the SFX-L form factor (125mm width x 63.5mm height x 125mm depth). Carefully route the fully modular cables to optimize airflow. Connect the appropriate cables to your components (motherboard, GPU, storage).
Compatibility: The PSU is compatible with ATX 3.1 standards, ensuring support for the latest CPUs and GPUs. Make sure your motherboard has the appropriate power connectors.
ARGB Lighting: Connect the ARGB cable to an ASUS or ROG motherboard with Aura Sync for lighting control.
Care: Keep the PSU free from dust. Use compressed air to clean the fan and vents periodically. Ensure proper cable management to prevent airflow restrictions. Avoid overloading the PSU beyond its 1200W capacity.
Warranty: The PSU comes with a 10-year warranty. Keep the original packaging and proof of purchase for warranty claims.
