The ASUS ROG Loki SFX-L 750W Platinum is a compact, fully modular power supply for small-form-factor gaming PCs. It combines 80 PLUS Platinum efficiency, ATX 3.0 compatibility, and a PCIe 5.0-ready 16-pin cable for modern graphics cards, making it suitable for powerful compact builds.
Recommended For
- Small-form-factor PC builders using an SFX-L-compatible case who need a 750W power supply for a single-GPU gaming or workstation system.
- SFF gamers who want native ATX 3.0 and PCIe 5.x support for a modern graphics card with a 16-pin power connector, without using adapter cables.
- Quiet-conscious compact-PC users who prioritize low PSU noise during desktop work, media use, and moderate gaming loads.
- PC modders building visible or ASUS Aura Sync setups who want fully modular cabling, sleeved-style cables, and addressable RGB on the power supply.
- Builders who value power efficiency and stable electrical performance in a compact system used for sustained gaming, rendering, or other GPU-heavy workloads.
Real-World Use Scenarios
- Building a compact Mini-ITX gaming PC with a single upper-midrange or high-end graphics card: the SFX-L format, fully modular cabling, and native 16-pin GPU cable help keep the build organized, while the large fan and semi-passive operation can keep typical gaming sessions relatively quiet. ([asus.com](https://www.asus.com/news/yoljqqud1iaexxmt/?utm_source=openai))
- Upgrading a small-form-factor PC to a newer PCIe 5.0 graphics card: the included 16-pin cable avoids relying on a separate adapter, so installation is cleaner when the case has enough room for the cable bend and connector. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-loki/rog-loki-750p-sfx-l-gaming-model/spec/?utm_source=openai))
- Running a compact gaming-and-workstation system with a Ryzen 7 or Ryzen 9 processor, discrete graphics, and multiple storage drives: users commonly pair the Loki 750W with Mini-ITX systems for gaming, engineering software, virtualization, or general productivity, provided total component power remains within the 750W class. ([reddit.com](https://www.reddit.com/r/buildapc/comments/1htn2wt?utm_source=openai))
- Assembling a quiet living-room or desk-side gaming PC: at light and moderate loads, independent Cybenetics testing recorded zero fan speed and low measured noise, so the PSU is less likely to add audible noise during browsing, video playback, or lighter gaming. ([cybenetics.com](https://www.cybenetics.com/evaluations/psus/2053/en/?utm_source=openai))
- Creating a visible showcase PC with synchronized lighting: the ARGB fan and Aura Sync support let builders coordinate PSU lighting with compatible ASUS or ROG components, making the unit practical for windowed SFF cases where the power supply is visible.

Reference Q&A
Q: ASUS ROG Loki 750W or Corsair SF750 for a small-form-factor PC?
A: Choose the ASUS ROG Loki 750W when you need SFX-L compatibility, a native 16-pin PCIe cable, ATX 3.0 support, a 120mm fan, or addressable RGB lighting. Choose the Corsair SF750 when the case requires the shorter true-SFX format: the SF750 is 100mm long, while the Loki is 125mm long. Both provide 750W and 80 PLUS Platinum efficiency, but the Corsair is generally the more space-efficient option and the Loki offers newer GPU-power connectivity on this model. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-loki/rog-loki-750p-sfx-l-gaming-model/spec/?utm_source=openai))
Q: Is the ROG Loki 750W worth choosing over a 650W SFX power supply?
A: Choose the Loki 750W for a higher-power gaming system, a modern graphics card using a native 16-pin connection, or additional capacity for future upgrades. A 650W SFX unit is more appropriate when the system has moderate power requirements and the case prioritizes the smaller true-SFX form factor. The Loki adds 100W of rated output, Platinum rather than Gold efficiency, ATX 3.0 support, and a bundled 16-pin PCIe cable, but its SFX-L chassis is longer than compact 650W SFX alternatives. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-loki/rog-loki-750p-sfx-l-gaming-model/spec/?utm_source=openai))
Q: Should I buy the ROG Loki 750W or step up to the Loki 850W?
A: Choose the Loki 750W when the planned system’s peak power comfortably fits within 750W and case clearance is limited. Choose the Loki 850W for a higher-power CPU and GPU combination, sustained CPU-and-GPU workloads, or more upgrade margin. The two models share the 125 x 125 x 63.5mm SFX-L dimensions and Platinum efficiency, so the main decision is power capacity rather than physical size. The 850W model provides 100W more output and a higher 12V capacity. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-loki/rog-loki-750p-sfx-l-gaming-model/spec/?utm_source=openai))
Q: Is the ROG Loki 750W a good upgrade from an older 650W or 750W SFX-L PSU?
A: The Loki 750W is a practical upgrade when the existing PSU lacks native 16-pin GPU power, ATX 3.0 compliance, Platinum efficiency, or a long warranty. It is less compelling as a replacement if the current unit already provides adequate wattage, modern GPU connectivity, and acceptable noise. Independent Cybenetics testing reports high efficiency, low ripple, and an average noise result in the Lambda A range, while ASUS specifies a 10-year warranty and default 0dB fan operation. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-loki/rog-loki-750p-sfx-l-gaming-model/spec/?utm_source=openai))
Q: Will this power supply fit my small-form-factor PC case?
A: It is designed for SFX-L installations and measures 125 x 125 x 63.5 mm. Check that your case explicitly supports SFX-L clearance; the included ATX adapter bracket can support installation in some ATX-compatible cases, but it does not guarantee fit in every case.
Q: Does it include the cable needed for a modern graphics card?
A: Yes. It includes one native PCIe Gen 5 16-pin cable rated to deliver up to 600W to a compatible graphics card. It also includes three PCIe 6+2-pin connectors for graphics cards that use traditional power plugs. Confirm the graphics card's connector and recommended PSU wattage before buying.
Q: Is 750W enough for a gaming PC?
A: 750W is suitable for many mainstream and high-performance gaming systems, but adequacy depends on the graphics card, processor, drives, and other components. The unit provides up to 62.5A on the 12V rail and supports ATX 3.0 power excursions, but systems with especially power-hungry graphics cards may require a higher-wattage PSU.
Q: Will it run quietly in a compact PC?
A: It is designed for low-noise operation with a 120mm PWM-controlled fan, ROG heatsinks, and Lambda A certification for noise levels below 25 dB. Actual noise depends on system load, ambient temperature, case ventilation, and fan-control behavior.
Q: Can I reuse modular cables from another power supply?
A: Do not reuse modular cables from another PSU unless the manufacturer confirms exact compatibility. Use the cables included with this unit or cables specifically approved for this model, because modular PSU pinouts can differ even when connectors look the same.
Q: Is the ASUS ROG Loki 750W a good choice for a high-performance small-form-factor gaming PC?
A: It is suitable for an SFF gaming PC when the case supports the 125 mm SFX-L format and the system’s estimated power requirement fits within 750W. It includes ATX 3.0 support and a native 16-pin PCIe cable for compatible graphics cards. The main trade-off is that SFX-L is longer than standard SFX, which can reduce clearance for cables or case components.
Q: Is the ASUS ROG Loki 750W worth buying over another 750W SFX power supply?
A: It is worth considering if you need SFX-L sizing, 80 PLUS Platinum efficiency, a native 16-pin PCIe cable, sleeved modular cables, or ASUS ARGB integration. If those features are not important, community discussions describe alternatives such as the Corsair SF750 as competitive, so price and case clearance become the main deciding factors.
Q: Is the ASUS ROG Loki 750W quiet enough for a compact PC?
A: The unit is Lambda A certified with a specified noise level below 25 dB, and Reddit users commonly describe the Loki as quiet. However, at least one discussion reports intermittent loud fan behavior, so buyers who prioritize silence should verify the return policy and consider the possibility of unit-to-unit variation.
Q: Can the ASUS ROG Loki’s RGB lighting be turned off?
A: Yes. The included ARGB cable does not need to be connected for the power supply to operate, and Reddit users report that leaving the RGB cable disconnected keeps the lighting off. This makes the PSU usable in builds that do not use RGB.
