Overview
The Lian Li SP750 750W SFX Power Supply is Lian Li's attempt to bring its case-building pedigree into the power supply space, and it arrives with a brushed aluminum housing that immediately sets it apart from the plastic shells most rivals ship in. SFX wattage is a different conversation than ATX wattage — fitting 750W into a unit this small involves real engineering trade-offs, and Lian Li has clearly done its homework. This compact PSU sits in the upper-mid price tier, competing directly with Corsair's SF series and SilverStone's established SFX lineup. For small form factor builders, that level of competition is genuinely welcome.
Features & Benefits
The SP750's zero RPM fan mode is where things get practically interesting. Under light-to-moderate loads — browsing, streaming, or even casual gaming — the fan simply does not spin. Complete silence. The fully modular braided cables matter more in an SFX build than they would in a full tower, because every centimeter of routing space inside a compact chassis is genuinely earned. Japanese electrolytic capacitors signal long-term reliability in a way budget competitors rarely match. The 80 Plus Gold rating also helps in chassis with limited airflow, where a less efficient unit would dump noticeably more heat into an already confined space.
Best For
This SFX power supply is a natural fit for mini-ITX gaming builds where space dictates every component decision. If you are pairing it with a power-hungry GPU like an RTX 4080 or an RX 7900 XT, 750W provides comfortable headroom without overspending on wattage you will never use. It suits home theater PC builders equally well — quiet operation in a living room environment is hard to put a number on. Builders already in the Lian Li ecosystem will appreciate how the white finish pairs with popular Lian Li cases. Those stepping up from an older, lower-wattage SFX unit will likely find this compact PSU a meaningful upgrade.
User Feedback
With a 4.4 out of 5 score across 378 ratings, the SP750 earns its reputation. Cable quality and flexibility are the most-cited positives — buyers consistently note that the braided modular set makes routing feel less like a battle inside a confined case. The zero RPM behavior also earns repeat praise for working as advertised without any quirks. On the critical side, a meaningful number of users flag SFX bracket compatibility as something to research before purchasing, since not all cases handle it the same way. The white finish, while attractive, shows dust accumulation faster than a darker option would. Also worth noting: the Amazon listing has some color inconsistencies, so confirm the exact variant before ordering.
Pros
- Zero RPM fan mode delivers genuine silence during light loads — not just quieter, actually inaudible.
- Fully modular braided cables make routing noticeably less painful inside cramped mini-ITX cases.
- Japanese electrolytic capacitors point to above-average long-term reliability versus cheaper SFX competitors.
- 80 Plus Gold efficiency keeps waste heat low, which matters a lot in chassis with restricted airflow.
- The brushed aluminum housing feels premium in hand and looks the part next to high-end case hardware.
- 750W in an SFX footprint covers most high-end single-GPU builds without wattage anxiety.
- No ATX adapter bracket required for most ITX and HTPC chassis — one less compatibility headache.
- Buyer ratings are strong and consistent across a meaningful sample size, suggesting quality control is solid.
- The SP750 competes credibly on build quality against Corsair and SilverStone without feeling like a second-tier entry.
Cons
- SFX bracket compatibility varies by case — confirm fitment before purchasing, not after.
- The white colorway accumulates visible dust faster than darker alternatives, especially in open-air or dusty environments.
- SFX units carry a real price premium over ATX equivalents at the same wattage — budget builders will feel it.
- Cable lengths, as with most SFX supplies, can feel limiting in larger-than-average ITX cases with awkward routing paths.
- Amazon listing inconsistencies between white and black colorways have caused confusion for some buyers at checkout.
- 750W leaves limited headroom for future GPU upgrades beyond the current high-end tier.
- Lian Li is newer to the PSU segment than rivals, so long-term reliability data is still accumulating.
- No SFX-L variant is available, which rules it out for cases that specifically require the longer form factor.

Suitable for:
The Lian Li SP750 750W SFX Power Supply is purpose-built for a specific kind of builder — one who has committed to a compact form factor and refuses to compromise on component quality to get there. Mini-ITX gaming rigs running high-draw GPUs like the RTX 4080 or RX 7900 XT are exactly the use case this unit was designed around, where 750W provides real headroom without requiring a chassis upgrade to accommodate a larger supply. Home theater PC builders will also find it compelling, since the zero RPM fan behavior means the unit contributes nothing to ambient noise during movies or music. Enthusiasts already building within the Lian Li ecosystem get an added visual payoff — the white brushed aluminum finish integrates naturally with popular Lian Li cases. Anyone upgrading from an older or lower-wattage SFX supply will notice the jump in both build quality and cable management flexibility almost immediately.
Not suitable for:
The Lian Li SP750 750W SFX Power Supply is not the right call for every builder, and being honest about that saves real frustration. If your chassis takes a standard ATX supply, there is little reason to pay the SFX premium — you would be spending more for a physical advantage your case cannot even use. Builders running truly extreme workstation loads or planning aggressive dual-GPU experiments may find 750W uncomfortably close to the ceiling, and stepping up in wattage here means looking elsewhere in the SFX market. The white finish, while attractive, demands more maintenance discipline than a darker unit — dust shows up faster and more visibly on light-colored surfaces in open or poorly filtered cases. Budget-conscious builders should also weigh the cost honestly against capable ATX alternatives at the same or lower price points before committing.
