Pros
- Delivers 1000 watts in a compact 125mm (W) x 63.5mm (H) x 100mm (D) SFX form factor.
- Achieves 90.9% efficiency with 115 VAC input, meeting 80 Plus Platinum certification requirements.
- Operates silently with fanless mode at loads ≤40% and uses a 92mm FDB fan for cooling.
- Includes a 12V-2x6 (600W) cable with reinforced alloy terminals for next-gen GPUs.
- Features 100% Japanese 105°C-rated capacitors for stable performance and a 10-year warranty.
- Super flexible braided DC cables simplify routing in tight small-form-factor cases.
Cons
- Provides only one 12V-2x6 connector and three 6+2 pin PCIe connectors, which is a conservative configuration for a 1000W unit.
- Offers just five SATA connectors, which is minimal for builds requiring extensive storage.
- The 12V-2x6 connector's thin sense wires with stiff insulation can be challenging for aesthetic cable management.
- Efficiency with 230 VAC input misses 94% at 50% load for Platinum certification by 0.4%.
Dimension Scores

Best For
- Small Form Factor (SFF) PC builds with high-end GPUs requiring a 12V-2x6 connector.
- Gaming PCs where quiet operation at low loads is a priority.
- Compact workstations needing stable 1000W power delivery in a confined space.
Not Recommended For
- Systems with multiple older high-power GPUs that rely on numerous 6+2 pin PCIe connectors.
- Builds requiring more than five SATA devices for storage.
- Users prioritizing maximum peripheral expansion over compact size.
Watch Out For
- The 12V-2x6 cable's thin sense wires with stiff insulation can make neat routing difficult if you're particular about cable aesthetics.
- If your build uses many SATA drives, the five available SATA connectors might be a limitation.
- While ATX 3.1 compliant, the single 12V-2x6 and three 6+2 pin PCIe connectors might not suit all multi-GPU configurations.

What Buyers Say
This Lian Li SFX PSU packs a serious punch for its size, delivering 1000W with impressive electrical performance, especially its voltage regulation and ripple suppression. Reviewers noted its quiet operation thanks to the fanless mode at lower loads, which is a huge plus for SFF builds. The flexible, braided cables are a thoughtful touch for tight spaces, though the 12V-2x6 cable's stiffness was mentioned as a minor aesthetic challenge.
“Man, this thing is tiny but it pushes serious power! My SFF build is finally quiet and I don't have to worry about my 4090. Just wish it had more SATA plugs, but whatever, I'll make it work.”
Common Praise
- Exceptional power density for its compact SFX size.
- Voltage regulation maintains 0.8% deviation on the 12V rail.
- Ripple suppression achieves outstanding results, with 24mV on the 12V rail.
- Fanless operation at ≤40% load keeps the system silent during light use.
- Super flexible braided modular cables make routing easier in small cases.
- Includes a 12V-2x6 (600W) connector for modern, high-power GPUs.
Common Complaints
- Cable configuration is conservative, with only one 12V-2x6 and three 6+2 pin PCIe connectors for a 1000W unit.
- Limited to five SATA connectors, which can be insufficient for storage-heavy systems.
- The 12V-2x6 connector's thin sense wires with stiff insulation can be tricky to manage aesthetically.
Ownership Tips
- The fanless mode actually works as advertised, keeping things dead silent when just browsing or doing light work.
- The flexible cables are a lifesaver in my cramped ITX case; they bend way easier than my old PSU's cables.
- The included power cord with the inline switch is super handy for power cycling without digging around in the back of my case.
- The 12V-2x6 cable feels really robust, but those little sense wires are a pain to get perfectly straight for a clean look.
Frequently Asked Questions

Buying Guide
When you're looking at a power supply, especially for a compact PC, you need to think about how much juice your components will pull and if the PSU can actually deliver it consistently. Don't just look at the wattage; check the efficiency rating, which tells you how much power is wasted as heat. Also, consider the physical size and the types of connectors you need for your specific graphics card and storage drives.
Wattage (1000W)
This is the maximum power your PSU can supply. A 1000W unit is overkill for most basic systems but necessary for high-end gaming PCs with powerful CPUs and GPUs, ensuring stable operation and headroom for future upgrades.
Form Factor (SFX)
SFX means Small Form Factor. This dictates the physical size of the power supply. An SFX unit is much smaller than a standard ATX PSU, which is crucial for fitting into compact cases like ITX builds.
80 Plus Platinum Certified
This certification indicates the power supply's energy efficiency. Platinum means it converts at least 89% of AC power into DC power at 100% load, and 92% at 50% load, reducing wasted energy and heat compared to lower-rated PSUs.
ATX 3.1 & PCIe 5.1 Compliant with 12V-2x6 Connector
This ensures the PSU is built to handle the power demands and transient spikes of the latest graphics cards, especially those that use the new 12V-2x6 power connector, preventing system instability or shutdowns.
Alternatives
If this unit doesn't fit your needs, look for an ATX form factor power supply if you have a larger case, or an SFX-L unit for a slightly larger SFX option, paying close attention to the number and type of PCIe and SATA connectors.
