Asus has put a lot of work into breaking into the PSU industry and has produced several excellent PSUs. Asus needed to establish a significant footprint since the tiny form factor industry is continually expanding. Three products in the Rog Loki SFX-L series each have a power output of between 750 and 1000W. The three variants are all quiet since they have all received certification from Cybernetics with Platinum efficiency ratings and LAMBDA-A and LAMBDA-A+ noise ratings.

The power supply unit (PSU) frequently receives less study and attention in the field of PC gaming and enthusiast builds. However, a high-quality PSU is the unsung hero that guarantees your gaming setup operates smoothly, effectively, and consistently.

  1. Price: Higher efficiency and premium features often come with a higher price tag, potentially making the ROG LOKI SFX-L 750W more expensive compared to non-Platinum-rated or less-known brands.
  2. Limited Availability: Being a specialized product with a specific form factor and brand, availability might be limited, making it harder to find or potentially leading to longer waiting times.
  3. Compatibility: While the SFX-L form factor is versatile, it might not fit in all cases, especially smaller ones designed for standard SFX or ATX power supplies. Ensure compatibility with your case before purchasing.
  4. Power Overkill for Some Builds: A 750W power supply might be overkill for some gaming setups, especially those with lower-powered components. Opting for a lower wattage might save money without sacrificing performance.
  5. Lack of RGB Control: Although some users might appreciate the aesthetics, others may find the RGB lighting unnecessary or wish for more control options, such as customizable lighting effects or synchronization with other components.
  6. Possible Cable Length Issues: While modular cables aid in cable management, they might also come with limitations in terms of length, potentially causing difficulties in larger cases or specific cable routing scenarios.
  7. Brand Loyalty vs. Value: While ASUS is a reputable brand, some users might prioritize value over brand loyalty and find similar features at a lower price point from other manufacturers.
  8. Limited Fan Control: Depending on the design, the power supply might have limited fan control options, potentially leading to louder operation under heavy loads or in warmer environments.
  9. Noisy Fans: While efficient design often translates to quieter operation, some users might find the included fans noisy under certain conditions, especially if they prioritize a near-silent PC.
