One of the key features of the new Pure Power 11 includes a lower RRP entry price onto the market when compared against the previous Pure Power 10 series. be quiet! have also increased the warranty from 3 years to 5 years which shows their confidence in the components used and they have also made them quieter. This is something be quiet! are well known for in their products and their charge to impeccable performance combined with solid acoustical performance is something not to be sniffed at.

Let’s take a look at the official specifications and some of the new features in detail.

be quiet! Pure Power 11 600W Specifications & Features

• 80PLUS Gold certification. Pure Power 11 with 400 watts and above feature up to 92%
power conversion efficiency.
• Continuous power. A multi-rail configuration with two 12V rails ensures rock-solid voltage stability
for powerful multi-GPU systems. Pure Power 11 can provide up to 96% of its power on its 12V rails.

be quiet! Pure Power 11 600W Closer Look

Taking a closer look at the be quiet! Pure Power 11 600W power supply to us, looks exactly identical to other models that we have reviewed in the past. If you’re not familiar with be quiet!’s usual power supply design, the new Pure Power 11 has an all matte black design and features a semi-modular design. On the rear is honeycomb venting with a single on and off power switch which is located right next to the 3 pin power lead input.

Inside all of the Pure Power 11 power supply models is a be quiet! 120mm 1800rpm fan designed for silent and efficient cooling under load. The maximum noise this power supply makes at full load under max wattage is a meagre 22.9dBa which is stunning, to say the least.

Hardwired into the power supply is a 24 pin ATX motherboard power connector along with an 8 pin 12V ATX CPU power connector too. The rest of the cables are modular and feature a flat cabling design to aid in easier cable management. Pictured above is a clear diagram and list of cables included with this particular 600W model of the Pure Power 11.

The top vent allows the 120mm fan to blow air outwards and has a familiar orange ring around the edge which looks good. be quiet! has a knack of taking a basic design and making it look stylish.

The be quiet! Pure Power 11 600W Review: Performance and The Verdict

Since we don’t currently have access to an ATE load tester, a multimeter is used to show each of the power supplies performance on the 3.3v, 5v, and 12v rails. Although we can’t do full load tests, we can provide relative information regarding variance and fluctuation of current and ripple on the rails which is integral and indicative of quality in a power supply.

To perform the above tests, the components and methodology were as follows:

Intel Core i7-7820X @ Stock
ASUS X299 TUF Mark 1
ZOTAC GTX 1060 – Power limit set to the maximum
Crucial (2x8gb) 32GB DDR4 Ballistix Elite 3000MHz
1 x 525GB Crucial MX300 SSDs

Voltages will be monitored via a multimeter and the AC power draw will be monitored via a power monitor when drawn from the wall. For the idle test, the system will be simply booted up and let to run into windows and after 5 minutes when the power draw has levelled out, the readings will be taken.

To load and apply power to the power supply, a combination of IBT and Furmark will be run to put as much strain on the power supply as possible. After 10 minutes the readings will be taken and to ensure maximum strain, the CPU will be overclocked to 4.8GHz. Depending on the power of the power supply, multiple graphics cards could be used in line with how comfortable I feel that the power supply will cope with such a load. In the case of this unit, the GTX 1060 doesn’t support SLI. We will endeavour to improve our testing methods over 2018 though!

ATX themselves specify that a fluctuation and variable of 5% is acceptable so to number crunch it means that:

3.3V = 3.135V-3.465V is acceptable
5V = 4.75V-5.25V is acceptable
12V = 11.4V – 12.6V is acceptable.

Any readings outside of these figures will be an automatic fail.

Idle
3.3V = 3.23v
5V = 5.07v 
12V = 12.3v

 

Load
3.3V = 3.31v
5V = 5.12v
12V = 12.2v

 

Performance on the be quiet! Pure Power 11 600W is as good as it can be and showed no massive variations from what we are used to in our testing. This power supply has an 80PLUS Gold efficiency rating and we see no evidence from us that this model wouldn’t be as efficient as it says it is.

What’s hot:

  • New 5-year warranty on all Pure Power 11 models (Pure Power 10 had 3-years)
  • £70 for an 80PLUS Gold rated 600W semi-modular power supply of this quality is great
  • Stylish as usual be quiet! design
  • Flat modular cabling is good for cable management
  • Improved overall quality from Pure Power 10 models

What’s not:

  • It’s currently sat at a highly competitive price point

There’s a lot of new and improved elements to consider if you’re looking at the new be quiet! Pure Power 11 range of power supplies. The most important of these include improving the efficiency rating from 80PLUS Silver to Gold and increasing the warranty from 3 years to 5 years on the new range. Internally be quiet! has added an extra heatsink for thermal performance and has dropped the use of capacitors at the end of their 24 pin motherboard cable for improved ripple design. This is majorly important at full load and the less noise in the power, the better.

If you’re looking for a new power supply for a system your building or you’re looking to replace an older unit for a new shiny one, the new Pure Power 11 has you covered. For a respectable price of £70 at launch gets you the 600W model which we’ve taken a look at today, but alternatively, other wattage models from the Pure Power 11 range are also available as of today too.

Below is a list of models launched and a list of pricing in the UK, EU and USA regions:

be quiet! Pure Power 11 300W – £43/$40/€48
