Storytime gather around. I remember back in the day when Be Quiet! first approached us and sponsored one of our LANs. That first time while they were established in Europe, the US market was still new to them. So new that all of the power supplies that came in had their EU power cords. Well, things have changed, the Be Quiet! brand is well known and they have established their reputation for quality and as the name would imply, for keeping the noise down. So I’m always excited what something new from the Be Quiet! team comes in. This time around we have the Pure Power 11 FM in the 1000 watt variation. Their Pure Power lineup is their more budget-friendly lineup and the FM means full modular which should fall right in the range that most people are looking for so let’s check out what they have going on.

LanOC Reviews only covers the features of power supplies due to not having the equipment to test them up to our standards. Because of this, you will not see a performance section, a final verdict, or awards. Therefore, we prefer to call this a preview rather than a review. Thank you for understanding; we keep our standard to the absolute highest for you, our reader.

For the packaging on the Pure Power 11 FM 1000W, I don’t think anyone even remotely familiar with Be Quiet! will be surprised with the packaging design. It is black very black. Black is kind of their thing and it's no different here with the front of the box having a black background and then on the left side, they show that this is part of their Essential line with a white strip. They have a picture of the PSU in the center which I really like and then below that the model name is the largest font along with the wattage below that in bold. The white and orange be quiet logo is up in the top right corner and isn’t too large and then on the top left, they have the 80 Plus Gold badge. Most of what you need to know is on the front except maybe that this is an ATX power supply but it is still simple and clean. On the back, they just explain a little more about the be quiet brand and then have a basic specification listing that breaks down the power and your serial number is back here.

When you open the box up, they have a cardboard panel giving a little extra protection and it also divides the power cord and other accessories away from the PSU and the other cables. The Pure Power 11 FM 1000W itself is also wrapped in its bubble wrap bag for even more protection as well but be quiet doesn’t include any of the fancy reusable bags for the PSU or for the cables. I don’t mind using less packaging for the PSU but do still prefer to have a bag to keep the extra cables in.

For documentation, you get a Pure Power 11 FM user manual which is designed for both the 1000w and 850w models and just gives you a quick rundown on everything.

The Pure Power 11 FM 1000W comes with a power cable of course. In addition to that, they also include a baggie of long black zip ties, you get 5 in total. Then there is also a small bag which has the black mounting screws as well to go with everything else. Then like I said the cables don’t come in their own bag, they just have one huge twist tie around them.

Photos and Features

So if you haven’t seen a be quiet! power supply before, like I said earlier their theme is black. So the Pure Power 11 FM 1000W looks like your standard black power supply and has a nice textured finish to the powder coating. On one side they have the be quiet! branding stamped into the metal housing for a nice embossed look.

On the other side of the Pure Power 11, FM 1000W is where they have the main information sticker. This lets you know the model as well as the breakdown of the power as well as all of the required certification logos as well. You also have your serial number on this side in case of any warranty work in the future. The Pure Power 11 FM 1000W has a 5-year warranty which matches up with warranties from the competition like Corsair.

Even the top of the Pure Power 11 FM 1000W is simple and to the point with nothing at all going on as well.

On the flip side, the fan side of the Pure Power 11 FM 1000W is the only place where the Pure Power 11 FM 1000W starts to look like more than your basic no-name power supply. They have a traditional wire grill covering the fan with a nice black finish to tie everything together. But behind that, we can see the be quiet! fan hiding behind the grill. The fan has a white ring around the outside which looks a little like the RGB light wings fans but without the lighting and then it has 7 blades on the black fan. Each blade has Be Quiet’s rippled effect to keep the noise down and then in the center the only color on the PSU is the be quiet! logo which is white and orange. The 120mm fan is a little smaller than I expected, a lot of PSUs these days have been packing in a 140mm fan.

The exhaust end of the Pure Power 11 FM 1000W is of course mostly filled with small hexagon-shaped holes to exhaust the air that the fan brings in out the back of your case. This end also has your standard power plug with support for 100-240 volt AC and a power switch next to that.

image 12

The inside end of the Pure Power 11 FM 1000W is where the full modular cables come in and there is a plug for each of the included 9 cables. On the left the 24-pin motherboard power has two plugs, one is a 20 point and the other is an 8-pin. Next to that, the accessory cables have 5-pin plugs which are packed in tightly together due to their clip being at the end of the cable, not the middle. They have those labeled as drive cables. To the right of that are two 10-pin plugs which are labeled P8 for the CPU power cables. Then the three PCIe cables have PCIe labels and are down at the bottom, those are 12 pin connections.

The Pure Power 11 FM 1000W is a standard ATX power supply which means it is 150mm wide and 86mm tall. The only dimension that changes depending on the power supply is the overall length and the Pure Power 11 FM 1000W is a little longer than your 150 x 150 design at 160 mm in total length. As the model name indicates it is 1000 watts but they do also have models that are 550, 650, 750, and 850 watts as well in the Pure Power 11 FM range. All of them are 80 Plus Gold rated which is normally a nice happy medium in being efficient while also keeping costs down.

For the wiring, be quiet! set the Pure Power 11 FM 1000W up with nine wires in total and all of the wires are made with the black flat flexible cabling that I always prefer when cleaning wiring up. The 24-pin motherboard power however has been wrapped over top of everything in black sleeving as well which I am not as big of a fan of. The 24-pin is 2 feet long just like the two 8-pin CPU power cables as well. Then the Pure Power 11 FM 1000W has three different PCIe power cables, each cable has two full plugs at the end and both connections on each cable is a 6+2 plug that will work with 6 or 8 pin plugs. What is interesting though is two of the cables have the standard plug, then cable coming out of that plug going to the next with the first plug 21 inches long and then 6 inches for the second. But be quiet’s third cable is split at the original plug and looks more like two independent cables so you have options. Then the last three cables are all accessory power cables. These are all much longer and rather than have one cable for SATA plugs and one for Molex connections they have one cable with a mix which I really like. Often most of your power needs will just be SATA plugs but you always have that one device that needs Molex so having them both on one cable means you may only need just one cable, not two. The mixed cable has two SATA at 21 and 26 inches then Molex at 32 and 38 inches as well as an old floppy power as well at the end. The other two cables are full SATA power and both have four plugs at 21,26,32, and 38 inches.

What I like about the Pure Power 11 FM 1000W from Be Quiet is that they have designed it aesthetically to be clean and simple with its all blacked-out design. But in areas like the fan, it stands out compared to other budget-focused models. In other words, the money is invested in the areas that matter, not in fancy styling LED screens or RGB lighting. The Pure Power 11 FM lineup is available in all of the wattages that you might need including higher wattages like this 1000 watt version that will help support the power-hungry CPUs and GPUs that we have been seeing recently. You get full modular cables and almost all of the cables are the easy to work with flat flexible cables, I do wish the 24-pin cable wouldn’t be sleeved but it does have the flat cabling behind the sleeving so I guess you could remove it if you wanted. It has a 5-year warranty which isn’t too bad and 80 plus gold certification does seem to be the sweet spot right now for efficiency and cost which is exactly what they are aiming for with the Pure Power 11 FM lineup.

Like I mentioned before, none of this is performance testing so I would still recommend checking out full reviews which include that as well. But as far as features go, I like what Be Quiet is doing here. For pricing, the 1000-watt model is selling for $159.99 on Amazon and is a little cheaper on Newegg. That is cheaper than the EVGA SuperNOVA 1000 G6 which is $174.99 and the Corsair RM1000x which is $169.99 which have a similar configuration. The EVGA 1000 GT on the other hand is a little cheaper at $149 so the Pure Power 11 FM 1000W is priced right around where it should be assuming its performance matches its feature set.
