be quiet! SFX L Power 600W Review
be quiet! SFX Power 3 600W 600W 80 Plus Gold fully modular power supply, ATX 2.x certified, SFX form factor, standard PCIe connectors, 3-year warranty, Great Wall/CWT platform.
The be quiet! SFX Power 3 600W is be quiet!'s compact SFX offering for small-form-factor builds that still want the brand's low-noise reputation in a shrunk-down chassis. Rated 600W at 80 PLUS Gold (Cybenetics Gold efficiency / A- noise), it's built on a Great Wall/CWT platform with a 92mm rifle bearing fan. Fully Modular cabling and a 125mm chassis depth make it a realistic fit for a small-form-factor build with a single mid-range GPU, and it's backed by a 3-year warranty.
Efficiency, Noise, and Build Quality
The SFX Power 3 600W carries an 80 PLUS Gold certification and a Cybenetics Gold efficiency / A- noise rating, translating to consistently high real-world efficiency at typical 50% load and low fan noise thanks to its 92mm rifle bearing. It uses a Great Wall/CWT platform, a common approach at this price point that keeps the unit affordable without meaningfully hurting day-to-day reliability.
Connectors and Cabling
Connector layout is 1x 24-pin ATX, 1x EPS 4+4, 2x PCIe 6+2-pin, 4x SATA, 2x Molex. It relies on traditional 6+2-pin PCIe connectors, so an aftermarket or bundled adapter is needed to power a 12VHPWR/12V-2x6 GPU natively. Cabling is fully modular, using standard flat or ribbon cables, with a single +12V rail design that simplifies load balancing across connectors.
Comparison to Alternatives
Against the MSI MAG Ai1600TS PCIE5 (MSI's 1600W Titanium workstation flagship), the be quiet! SFX Power 3 600W matches its wattage class but differs on connector generation and OEM platform, making the choice mostly about brand ecosystem, warranty length (3 years here), and whether native PCIe-only connectors matter for your GPU. Compared with the Corsair RM850x (Corsair's ATX 3.1 850W Gold mainstay), the SFX Power 3 600W sits in the compact/mainstream bracket at 600W, so the decision usually comes down to matching wattage headroom to your actual GPU/CPU combo rather than one being categorically better.
Our verdict

Expert rating8.2 / 10
A solid 600W Gold-rated SFX unit for a small-form-factor build with a single mid-range GPU, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
Best for
- Builders targeting a small-form-factor build with a single mid-range GPU
- Anyone who wants fully modular cabling with standard PCIe connectors
- Systems where a 3-year warranty and Gold-tier efficiency matter
Not for
- Builds needing more than 600W of continuous headroom
- Buyers who need a full-size ATX chassis
- Cost-sensitive builds better served by a lower-tier 80+ Bronze unit
