Product Description

be quiet! SFX-L Power 500W 80 Plus Gold Modular Power Supply UK Plug

The SFX-L Power Series from be quiet! represents a compact power supply that makes for the perfect choice for Mini-ITX PCs and compact gaming systems. As such it offers the ideal combination of quiet operation, functionality, reliability, and efficiency for compact systems with above average performance. Additionally, the PSU offers fully modular cabling in black, ideal for stowing away discretely inside your case.

500 Watt total output

Powerful 41.7 A single rail

80 Plus Gold certified

Quiet 120 mm fan

Fully modular cable management

1x 20+4-Pin / 1x 4+4-Pin / 4x 6+2-Pin / 6x SATA / 3x 4-Pin Molex


This SFX-L unit from be quiet! solves one of the few disadvantage of the classic SFX format, while the length of the PSU is very slightly increased. This change means it is capable of holding a larger and quieter 120 mm fan instead of an 80 mm fan, the likes of which are often annoyingly loud or noticeable when spinning up and down. The result is a powerful SFX-L power supply with an extremely high continuous output capacity of 500 Watts that is paired with a remarkably quiet fan that is capable of changing speeds in accordance with the load.

Thanks to the SFX-L format, the SFX-L Power is primarily aimed at users of Small Form Factor cases, although that doesn't mean it's not kitted out with an array of connectivity options with a minimum of trade-offs. Due to its 12.5 cm length, users should check before purchase that it is compatible with the case of their choice. The included back bracket also conveniently enables the PSU to be mounted in ATX-format cases.


The superb quality of the cabling used here makes installing the PSU a breeze, even in smaller cases. This is also thanks to the unit being fully modular and equipped with removable ribbon cabling to enable users to select just the cables they need most. The extremely high efficiency of the PSU, on average between 86.5 % - 89.5%, means it was awarded with the 80Plus Gold certification. This also means that only a relatively small amount of electrical energy is released as unwanted heat.

Instead of a 12V line split multiple times, this version offers a power single-rail setup with a full 41.7 Ampere as well as a multitude of protective circuity. The individually pluggable connections illustrate the power of this PSU: in addition to 20+4-Pin- and 4+4-Pin connectors, there are even four 6+2-Pin PCI-Express connections available. Six SATA connectors and three 4-Pin Molex connectors are present to supply peripheral devices like HDDs or DVD burners.
