Manufacturer description

The be quiet!

The Pure Power 11 sits in be quiet!'s mainstream PSU family. The brand's name points to its focus on low noise, which helps if your PC sits on a desk or in a living room. The all-black housing fits dark case interiors…

Frequently Asked Questions

Is 400W enough power for my gaming PC?

400W is enough for systems with integrated graphics or a low-to-mid-range GPU. Add up your CPU and GPU power draw first. High-end graphics cards usually need a larger power supply.

Will this power supply work with an older 20-pin motherboard?

Yes. The main connector is a 20+4 pin ATX design, so you can detach the 4-pin section for 20-pin boards or keep it attached for modern 24-pin boards.

Will the be quiet! Pure Power 11 400W fit in my case?

It's a standard ATX power supply, so it fits cases with a conventional ATX PSU bay. Small-form-factor cases built for SFX units may not accept it. Check your case's PSU spec before you buy.

Does it have the PCIe connector my graphics card needs?

The product listing doesn't give PCIe or SATA connector counts. Check the be quiet! spec sheet for the Pure Power 11 400W to confirm it has the connectors your GPU and drives need.

What warranty comes with this power supply?

The listing doesn't state warranty terms. Check the be quiet! product page or the retailer listing for current warranty coverage.
