Yes, Lian Li power supplies are good, with ATX 3.1 EDGE units and the SP750 rating well in reviews, though fan noise can rise under heavy load.
Lian Li built its name on clean cases, then moved into power. The lineup now spans compact SFX units for small rigs and ATX 3.1 models with the new 12V‑2×6 GPU plug. If you are weighing a Lian Li PSU against mainstays from Seasonic, Corsair, or Super Flower, this guide lays out where it shines, where it trails, and which model fits which build.
Are Lian Li Power Supplies Good For Your Build?
Short answer: yes for most use cases. Third‑party testing shows the EDGE EG1000/EG1200 deliver steady power, low ripple, and strong efficiency scores. The SP750 SFX also holds its own in small cases. The trade‑offs tend to be fan tone at higher loads and a shorter warranty than top rivals on some models.
What Makes A Power Supply Good
Before picking a unit, match it to clear checks that matter on day one and year three. Here is the quick list that guides the picks in this piece.
Safety And Standards
Modern GPUs hit short power spikes. ATX 3.1 raises transient targets and brings the updated 12V‑2×6 connector. Lian Li’s EDGE line is built for that spec. You can read the baseline rules in Intel’s ATX 3.1 design guide.
Electrical Performance
Good units keep voltage steady under load and keep ripple low. Review labs publish load regulation numbers and ripple in millivolts. Lower is better. Cybenetics and 80 PLUS give a quick read on efficiency; test labs dig into the rest.
Noise And Thermals
Zero‑RPM modes help at idle. The flip side is a clear spin‑up when the fan starts. At higher loads, fan curve and bearing choice shape tone. If your case has tight airflow, pick a PSU that stays quiet without needing lots of fresh air.
Warranty And Service
Top PSU brands often give 7–10 years on midrange and high‑end lines. Lian Li’s SP750 carries five years. EDGE warranty length varies by model and sales region. Longer terms signal confidence and reduce risk for long builds.
Size, Cables, And Fit
Match SFX and ATX to your case. EDGE models add an L‑shape shell that can tidy cable runs in dual‑chamber cases. Count the number of EPS and PCIe connectors you need, then add headroom for upgrades. For new GPUs, use the native 12V‑2×6 lead from the PSU when possible.
How Lian Li Stacks Up
EDGE Series (ATX 3.1/PCIe 5.1)
EDGE targets modern mid‑tower and full‑tower builds. Independent reviews of the EG1000/EG1200 show steady regulation, low ripple, and Platinum‑level efficiency on Cybenetics. The units meet ATX 3.1 and ship with the 12V‑2×6 lead. The L‑shape chassis helps in dual‑chamber cases, though it can be fussy in tight single‑chamber layouts. Fan noise stays modest at light to mid loads and climbs under heavy draw.
If you care about noise data and not just a logo, check Cybenetics’ public database for Lian Li’s EG1000 entries; the label shows Platinum efficiency and an A‑class noise grade. Here is one direct record for quick reference: Cybenetics test for EG1000G.
SP750 SFX (80 PLUS Gold)
The SP750 is built for small cases that still run a hungry GPU. It uses a semi‑passive fan profile that stays off at low loads, then spins up once you cross roughly two‑fifths of capacity. Reviews praise stable rails and power density, with notes that fan tone becomes noticeable once you push past mid load. Lian Li lists a five‑year term for this model.
Who Makes The Hardware
Lian Li brands the units; the platforms come from OEMs. Reviews identify Helly Technology as the maker behind the EDGE 1000/1200 designs. That matters because it tells you which platform you are buying, not just the sticker on the box.
Buying Advice By Build Type
4K Gaming With A Flagship GPU
Pick an EDGE 1000 or 1200 to land enough headroom for transient spikes from cards such as RTX 4090‑class models. Use the native 12V‑2×6 cable, give the plug a straight path, and avoid adapters when you can. If your case has a single chamber with cramped space near the PSU shroud, map the cable turn before you buy since the L‑shape shell can eat depth.
High‑Refresh 1440p Builds
EDGE 850 or 1000 fits midrange GPUs that still spike hard. You get ATX 3.1 behavior, modern protections, and modular wiring. If your case is quiet‑tuned, favor the higher wattage model so the fan stays in a lower part of its curve during gaming.
Compact SFF Rigs
SP750 shines in liter‑class and shoebox cases. Pair it with efficient CPUs and a single high‑end GPU, keep cable runs clean, and give the fan a clear path. Noise tends to rise once combined draw goes past the mid‑range, so plan airflow.
Workstations And Creator Towers
Multi‑NVMe and many‑core CPUs love steady rails. EDGE 1000/1200 bring the needed connectors and margin. If you push near full load for long renders, expect audible fan levels. Mount the PSU with some breathing room and keep dust off the intake filter.
Pros And Cons Of Lian Li PSUs
Pros
- Modern spec: ATX 3.1 units with native 12V‑2×6 for new GPUs.
- Strong lab scores on regulation, ripple, and efficiency from reputable test sites.
- Smart case fit: EDGE L‑shape shell can simplify cable runs in dual‑chamber designs.
- Clean styling and fully modular leads across the range.
Cons
- Fan tone rises at high loads; reports of spin‑up noise bursts on some EDGE samples.
- Shorter warranty than 10‑year rivals on select models.
- The L‑shape shell can complicate installs in some single‑chamber cases.
- Retail pricing often matches veteran brands with longer track records.
Noise, Efficiency, And Regulation In Plain Terms
On the bench, reviewers measure ripple on the 12V rail and hold it to stricter limits than the older ATX spec. Lian Li’s recent EDGE samples land low ripple and tight load regulation. That points to stable power delivery under gaming spikes and CPU boosts. Efficiency scores reach Platinum on select models, with measured averages over 90% across test loads in Cybenetics data. Quieter grades show up as A or A+, meaning the fan stays subdued for a large slice of typical use.
For those new to the spec side, ATX 3.1 also boosts transient handling over the 3.0 era and sets guidance for the 12V‑2×6 plug. Intel’s document linked above spells out those spike and cable details. Lian Li’s EDGE line lists full compliance on its product page.
Warranty, Service, And Risk
Warranty terms matter because PSUs can outlive two or three GPU cycles. SP750 carries five years. EDGE lines ship with terms that differ by region and model, so check the box before you buy. Rival lines from Seasonic, Corsair, and MSI often post 7–10 years. The shorter term does not mean weak parts, but it adds a bit of risk for long service life.
Cabling, Connectors, And Case Fit
Lian Li ships fully modular cables. EDGE packs the 12V‑2×6 lead for modern cards so you can skip dongles. Route that lead with a gentle bend, avoid sharp turns near the plug, and seat it fully. In dual‑chamber cases, the EDGE shell can keep the bundle tidy. In small single‑chamber cases, check GPU and PSU clearances to avoid crushed turns.
Quick Picks By Use Case
Quiet Gaming PC
Pick an EDGE 1000 and run it under half load during play. That keeps the fan in a calmer range and gives you growth room for a next‑gen GPU down the line.
Budget‑Aware Mid Tower
EDGE 850 hits a sweet spot for price, wattage, and ATX 3.1 features. Pair it with a Ryzen 7 or Core i7 and a high‑tier GPU without pushing into the loud zone.
Tiny SFX Build
SP750 fits tight layouts and brings Gold‑level efficiency. Keep dust filters clean so the zero‑RPM mode stays active at idle and light work.
Real‑World Checks Before You Buy
- Wattage: Add the GPU’s nameplate, add the CPU’s TDP, then add 200–300 W of headroom for spikes and upgrades.
- Connectors: Count EPS plugs, PCIe leads, and SATA runs. Pick the unit that meets your count without splitters.
- Standards: For new GPUs, pick ATX 3.1 with a native 12V‑2×6 cable.
- Acoustics: Read measured noise grades; A or better keeps rigs calm in daily use.
- Terms: If you want a decade of set‑and‑forget, compare warranty cards across brands.
