Be Quiet! is a name that came out of nowhere here in the USA. The company has built a name for itself overseas by introducing German engineering and ingenuity to the computer industry. They've won award after award for performance and design in Europe and the surrounding areas and have made the push to go worldwide with their offerings. They are doing very well over here in the States and we've always liked what they have shown us.

Up to this point, we've only looked at their enthusiast-class offerings when it comes to power supplies and they have proven to be great units. Today we are looking at something a little bit more on the lower-end of the spectrum.

The Pure Power L8 500W isn't meant to fuel a quad GPU system or break world records with overclocking. It is instead intended to power a budget gaming system with one high-end or two lower-end video cards.

The Pure Power L8 lacks modular cables, high efficiency, and a large price tag. Let's dig into the Pure Power L8 500W a little more and hope that it retains the quality and performance we've come to expect from them and that they haven't sacrificed too much to keep the cost down.

Specifications, Availability and Pricing


The Pure Power L8 500W power supply features dual 12V rails. The first 12V rail is rated for 28A, while the second is rated for 20A. They have a combined maximum output of 38A or 456W. The 3.3V rail is rated for 24A and the 5V rail is rated for 15A. These two rails have a combined maximum output of 120W. The 5VSB rail is rated for 3A. Maximum combined output for the Pure Power L8 500W is 500 Watts.


When we start talking about budget power supplies, features are often what define one power supply from another. Protections are the primary area to be cut, but Be Quiet! doesn't skimp here. They know that the protections are important and include SCP, OVP, OCP, OPP and OTP to keep you safe. What they do cut though is the modular cabling as all the cables for the Pure Power L8 500W are natively wired. This makes most sense, however, as it adds quite a bit to the cost of the unit since it requires additional connectors and a second PCB for the power supply to make it work.

They do keep all of the cables fully sleeved, though. The Pure Power L8 500W features an 80 PLUS Bronze efficiency rating. Finally, the Pure Power L8 500W is not rated for 100% continuous output, but Be Quiet! states that it can make it as that is their standard.

Be Quiet! has an MSRP of $74.90 on the Pure Power L8 500W power supply. Be Quiet! still hasn't reached the availability status that many other companies have so you have to do some searching to find their stuff. Luckily we were able to track it down on NCIX for $79.99 with $10.98 shipping at the time of writing, bringing the grand total to $90.97. This makes it slight higher priced than a middle of the road 500W power supply, but few have the same features as the Pure Power L8 500W. Be Quiet! backs the Pure Power L8 500W with a three year warranty.
