be quiet! Introduces Fully Modular Pure Power 11 FM, Upgrades SFX and TFX Models

be quiet!, the market leader for PC power supplies in Germany since 2007, is announcing three new power supply series. The Pure Power 11 FM is a fully modular version of the Pure Power 11, available in 550, 650, and 750 watts and aimed at mainstream computer users who appreciate the versatility of modular cables and 80 PLUS Gold efficiency up to 93.9 percent. Fans of small form factor builds can now upgrade their systems with the SFX Power 3 or TFX Power 3, which offer high performance in compact SFX and TFX form factors.

At be quiet!, Pure Power stands for peerless dependability and a comprehensive feature set at a competitive price point. The Pure Power 11 FM series is no exception: by exclusively using fully modular instead of fixed cables, only cables that serve a purpose are installed, resulting in a smoother airflow, lower temperatures, and easier handling inside the case. Pure Power 11 FM comes equipped with black flat cables for all common connections and a black sleeved 20+4-pin ATX power cable. With two independent 12 V rails for signal stability and up to four PCI-Express connectors (two for the 550 W model), Pure Power 11 FM is fully suited for silent PC configurations, workstations or even gaming systems with a powerful graphics card.
80 PLUS Gold efficiency and improved topology
Pure Power 11 FM is 80 PLUS Gold certified with an efficiency rating of up to 93.9 percent, a truly outstanding level for this PSU class. The most compelling benefits of this high efficiency are lower power consumption, lower electricity costs and a cooler, quieter operation. Pure Power 11 FM is equipped with LLC + SR + DC/DC technology for advanced stability and voltage regulation. Cooling is achieved with a silence-optimized 120 mm be quiet! fan with airflow-optimized fan blades, enabling the extraordinarily silent operation that be quiet! is famous for. As usual, all modern protection circuits (including UVP, OVP, SCP, OPP, OCP, and OTP) are integrated. be quiet! offers a 5-year manufacturer's warranty on Pure Power 11 FM.

SFX Power 3 and TFX Power 3: High performance in a compact form factor
The third iteration of these power supplies efficiently provides power for high-performance systems conforming to the space-saving SFX or TFX form factor. Despite their small dimensions, the SFX Power 3 and TFX Power 3 offer enough ports to power a modern Mini-ITX system and a rock-solid 12 V rail to support a dedicated graphics card. The SFX Power 3 series is available in 300 W and 450 W, offering 80 PLUS Bronze efficiency. TFX Power 3 is available in two different 300 W models: TFX Power 3 with 80 PLUS Bronze efficiency and TFX Power 3 Gold with particularly high efficiency of up to 91.7 percent (80 PLUS Gold). All of these new small form factors power supplies from be quiet! feature black cables for a contemporary look. A high-quality, temperature-controlled 80 mm fan takes care of quiet and effective cooling, and modern protection circuits (including UVP, OVP, SCP, OPP, and OCP) are integrated, making these power supplies a great choice for office and web clients, HTPCs, or small gaming systems.

Pure Power 11 FM, SFX Power 3 and TFX Power 3 will be available from April 23 at the following recommended retail pricing:

Fully modular's sole benefit is for people who throw out the included cables and buy custom colour or custom-length cables (for a super-cramped mITX build, for example)

Otherwise, surely it just drives up cost, complexity? The extra physical contacts take up space and presumably add resistance to the wiring too. It's not like you aren't going to use at least the 24-pin and the EPS connector.

It can also make for easier installation depending on the case and components, by wiring up components before installing them or wiring things up before installing the PSU. There are also advantages for those of us who mod/shorten our cables. But other than that, yes, at least a 24-pin plus 4+4 EPS will be used in every single build.


Great to see BQ continue to support SFF PSU types with efficient low-output units btw. Those 300W TFX units should be great for retrofitting entry level gpus into lots of office PCs, and 300W SFX 80+ Bronze delivers a reasonably efficient low-output PSU suitable for entry level atx and sfx builds all over (though I wish they were gold). Great stuff! Now if Intel can stop their shenanigans with 150+W boost power on their i5s we could build some tiny and beautifully efficient entry level rigs. Ryzen 5 does that job perfectly of course, but we need competition (as well as idiot-proofing). Oh, and gpus of course. Guess we could all just give this stuff up for the next couple of years. Sigh.

The previous TFX models were FSP rebrands at +20eur price.

This does look like it is going to be another rebrand.
The worst part about all this, is that FSP PSUs are not available. They are all sold out, while BeQuiet still has stock. It seems like FSP doesn't want to sell their brand products and chose to bulk sell to rebranders.

FSP has extremely limited distribution through consumer channels, while BQ has that in place already. Besides, pretty much no PSU maker actually makes their own PSUs - they're all rebrands (or slight tweaks) of some OEM's design. That's how the PSU business works. Also, at least from what I've seen previously, most FSP TFX units lack PCIe power connectors. But beyond that, the cost increase would likely be exactly the same should FSP start distributing and advertising such a niche product towards consumers. Getting them through a company with established customer service, distribution and broad reach is arguably better than if FSP sold them directly.

Fortron PSUs have always been fine, but you're much better off buying a rebrand from an established distributor because Fortron's EU service and spares availability is nonexistent.

Channel Well, Great Wall, Fortron, Superflower, Seasonic - only one of these brands has managed to make a half-decent retail presence. The rest are OEMs for ODMs that have established distribution and support chains.

the fan housing on the ATX models looks nice

All black with the white ring 'just works'

Hell no man, it makes system building tons easier. Wire them up at the opposite end and route back to the PSU

Am I missing a trick here? You have to route the cables still - why is routing from PSU to board easier than routing from board to PSU? The same cable has to be fed through the same holes and around the same bends whichever way you do it (Talking about the 24-pin and 8-pin EPS specifically, as those are the only difference between fully-modular and semi-modular)

because you got a big ass chonky weight of a PSU attached to one end?
I've changed PSU's in existing setups with fan wires and lighting systems everywhere, its absolutely easier to have the freedom to just disconnect that cable and adjust its location from either end


I dunno if you're used to working with E-ATX behemoths or something, but in compact cases its an absolute godsend

Prima.VeraNo 850W PSUs??
They probably already have plenty of options in higher wattage classes. Besides, Pure Power is an entry-level series. You don't buy an entry-level PSU for something requiring an 850W PSU (i.e. 10900k+3090 or similar).

Having one end permanently attached to the PSU makes clean routing much more difficult - unless you want any slack to be on the board end (which ... you don't) you have to connect (or at least roughly get the wire in place) there first, then route it. When the PSU is permanently attached, that means both ends of the cable are attached, which drastically limits your ability to twist and bend the cable (unless you're very fond of stressing your wires, that is). I've had to re-do cable management on non-modular PSUs 2-3 times due to twists and turns in the wire cascading down towards the PSU and into some highly stressed kink/twist/something making the side panel not fit on. If the PSU-side end can come loose, you just unplug it, twist the cable to relieve stress, then plug it back in.
