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.

The be quiet! SFX-L Power 80 Plus Gold PSU at a Glance:

  • Compact SFX-L form factor
  • 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

The Perfect Combination: SFX-L Form Factor

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.

Fully Modular Cable Management & 80Plus Gold Efficiency

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.

Nice little unit, but as per the other review no UK plug

by Jonny B star_border star star star star

Much like the other review (only other review at time of writing), my only disappointment with this PSU is the fact that no UK power lead is supplied, however thanks to the other review I was prepared for this eventuality.Works happily, and silently, in my 9600k system which has a GTX1070, both M.2 and SATA SSDs, Corair 115i 280mm AIO plus 2 additional 120mm fans.Another reason I chose this PSU was because it comes with an adapter plate allowing fitment in to standard ATX spacing, which in turn provides more clearance between the PSU and the GPU in the ITX case I'm using - more space = better cooling. The fact it's fully modular with all black cabling allows you to create a discrete and unobtrusive look in a smaller build.

Good SFX-L power supply; doesn't come with UK power lead (!)

by Mark Provan star_border star star star star

Bought it for a new Mini ITX build in a Lian-Li TU150 case. Fits fine and is quiet, as I hoped. No problems driving a Ryzen 5 3600 (non-overclocked) plus an MSI RX 5700 XT Gaming X 8GB.Internal cables are modular, all black and a ribbon style (wires glued together in a row) rather than braided or loose. Each supplied PCIe power cable has two 6+2 pin connectors on the end, so I only needed one cable from the PSU for my single GPU.Main (minor) gripe is that it comes only with a German-style power cable in the box. I had to dig out a random kettle plug lead to test my new system. Not exactly ideal if you don't have one to spare. I think this is actually against trading standards rules too -
