Dimension Scores
The 80+ Gold certification ensures over 90% efficiency at 50% load, and 750 watts is ample for many high-end SFX builds.
It features a 92mm FDB fan with a Zero RPM mode up to 40% load, but the fan can activate below 50% load during extended use.
It uses premium Japanese electrolytic capacitors and offers comprehensive protection mechanisms, backed by a 10-year warranty.
Being fully modular with anti-tangle embossed cables and a native 12V-2x6 cable simplifies routing and reduces clutter in compact cases.
Best For
- Small form factor (SFX) PC builds requiring 750 watts of power.
- Systems utilizing high-performance 50/40 series graphics cards needing a native 12V-2x6 connector.
- Users prioritizing a clean build with fully modular cabling in a compact chassis.
Not Recommended For
- Users with larger ATX cases where SFX form factor isn't necessary.
- Budget-focused builds that don't require ATX 3.1 or PCIe 5.0 compliance.
- Users who are extremely sensitive to any potential fan noise under load.
Watch Out For
- The fan's Zero RPM mode might not keep it silent during all low-load scenarios, as it can activate below 50% load in some setups.
- Previous iterations of the Lian Li SP750 (non-V2) were associated with serious reliability concerns, including reports of electrical issues and sparks.
- While the white model has a 5/5 rating from one review, the black version of the SP750 V2 shows a 3.3/5 average from 4 reviews, indicating some users encountered problems.

What Buyers Say
While the white version of this power supply has received a perfect 5/5 rating from one user, the black version shows a mixed bag with a 3.3/5 average from four reviews, suggesting some inconsistency in user experience. The previous SP750 model had concerning reports of electrical issues, though the V2 is explicitly an upgraded design. Users appreciate the truly white aesthetic of the white model, extending to the braided cables and terminals. The fan's Zero RPM mode is a plus for silence at low loads, but it does activate under sustained use, even below 50% capacity.
“Man, I needed a white PSU for my build and this one looks sick, but I'm kinda worried about that fan kicking on when I'm just browsing, and those old spark reports for the non-V2 model got me sweating a bit.”
Common Praise
- The white color extends to the braided cables and terminals, creating a cohesive aesthetic.
- The fully modular design simplifies cable routing and reduces clutter in small cases.
- The compact SFX size fits perfectly in space-limited builds.
- Includes a native 12V-2x6 cable for direct connection to modern GPUs.
Common Complaints
- The fan can activate and produce noise even when the system load is below 50%.
- Older versions of the SP750 were reported to have serious reliability issues, including sparks and loud electrical noises.
- Some users of the black SP750 V2 reported issues, leading to a lower average rating.
Ownership Tips
- The 'truly white' finish of the white model holds up, even on the cables and connectors.
- The fan's Zero RPM mode is effective for truly silent operation during very light tasks.
- Under gaming loads, the fan will engage, and the PSU won't remain completely silent.
- The native 12V-2x6 cable eliminates the need for adapters, simplifying GPU power connections.

Buying Guide
When you're picking a power supply, especially for a compact PC, you need to think about its physical size, how much power it can deliver, and if it has the right connectors for your parts. This Lian Li SP V2 is an SFX unit, meaning it's smaller than standard ATX power supplies, which is crucial for small cases. You also want to make sure it's efficient so it doesn't waste electricity and generate too much heat.
SFX Form Factor
This refers to the physical dimensions of the power supply. SFX units are significantly smaller than standard ATX power supplies, allowing them to fit into compact PC cases where larger PSUs simply won't. If your case specifies SFX, you need an SFX PSU.
80+ Gold Efficiency
This rating indicates how much power the PSU converts into usable electricity versus how much is lost as heat. 'Gold' means it's at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. Higher efficiency means less wasted energy, lower electricity bills, and less heat generated inside your PC.
ATX 3.1 & PCIe 5.0 Compliant with Native 12V-2x6 Cable
This is about future-proofing and compatibility with the newest, most power-hungry graphics cards. ATX 3.1 is the latest power standard, and PCIe 5.0 is for modern GPUs. The native 12V-2x6 cable is a direct, single cable connection for these new GPUs, replacing multiple older 8-pin connectors and preventing transient power spikes.
Alternatives
If this doesn't fit, look for an SFX-L or ATX form factor power supply if you have more case space, or a higher wattage unit if your components demand more than 750W.
