This may come as a shock to you, but be quiet! power supplies are all about...wait for it...exceptionally quiet operation. However that is not the only virtue the Pure Power 10 series extols. be quiet tells us that this PP10 has "peerless dependability" and "best-in-class features." Let's see if we can set it on fire!

Build Quality

As we already know the be quiet! Pure Power 10 600W features a single 120mm fan design like many other offerings on the market that has come to be the preferred standard for quiet cooling environments due to the ability to move a larger volume of air at slower speeds than a smaller diameter fan. While great for quiet computing environments the key criteria in our evaluation is whether or not the cooling solution is sufficient, not necessary it’s sound level or form factor.

External Build Quality

The exterior of the be quiet! Pure Power 10 600W looks nice enough for a mainstream product but it is a bit on the plain side. But, hey, vanilla ice cream is plain and vanilla ice cream can be good! In general, the Pure Power 10 has a layout that is typical for semi-modular single overhead fan units that have APFC. The fan guard itself, along with the trim around the fan, gives us a bit of color and style which is nice. The front of the unit has a sticker on it that labels our modular connectors and there is a small portion of the housing that is perforated under the fixed cables. When we move around to the back of the unit, we see that almost 1/3 of the rear is obstructed by the AC input receptacle and switch which seems like a bad idea from an exhaust stand point. Overall, the flat black finish that is used seems tough but it is nothing we have not seen a million times before. The one sort of high point here is the embossed be quiet! logo on the side of the unit which is something that you don't often get on high end units let alone mainstream one.

The be quiet! Pure Power 10 600W itself is ~6 1/4 inches long while the cables provide a serviceable length of ~19 to 24 inches to the first or only connector. The sleeving is a mix of the flat FlexForce style and standard wire loom. As always, the FlexForce ones are completely sleeved while the standard loom is a bit short of complete.

Internal Build Quality

Once we open the be quiet! Pure Power 10 600W we see an unit that is kind of sparse and looks a bit familiar. Overall, the FSP platform that is being used today is not FSP's highest end but it does feature an active clamp primary with synchronous rectification and DC-DC VRMs on the secondary making it decently modern. Looking over the unit, the few heatsinks we see here today are all rather small and they are paired with a "custom" rifle bearing Yate Loon fan rated at 0.3A at 12v. When we look at the single layer PCB used, we see that the top side is fairly clean and the soldering on the rear is also good. There is some hand work on the PCB but it is not bad overall.

The input filtering for Pure Power 10 600W begins on the housing itself by the AC input receptacle with a couple capacitors. It then trails onto the main PCB. As we move a bit past the input filtering, we come to the heatsink which houses the bridge rectifier and is wrapped in tape for some reason. Past this, we come to the PFC coil and behind this is the main input capacitor. This capacitor is a Teapo product rated at 420v 330uF 85C. Next to this capacitor we find the other heatsink on the primary side which house the PFC components, primary side power components, and switchers.

Moving on to the secondary, and past the transformers in the middle of the unit, we see that the secondary is dominated by a heatsink, some coils, and a few add-in PCBs. The heatsink here is for the 12v power components while the add-in PCBs house the VRMs and the protection circuitry. The thing with these PCBs is that they are all a bit askew which may not affect function but does look a bit sloppy. Sprinkled throughout the secondary are a number of Teapo standard capacitors. When we look at the rear of the modular PCB we see very nice soldering and a clean looking single layer PCB overall. When we move to the front of the modular PCB, we see that it is also very cleanly constructed and there are a few CapXon solid capacitors here.

Build Quality Summary

The be quiet! Pure Power 10 600W’s build quality would rank as generally good so long as you were expecting a mainstream level product from the outset. Luckily, we were! The exterior of the Pure Power 10 600W starts off well enough. Beyond the embossed be quiet! logo there is not much to the unit that is different from what you get on a myriad of other comparable products. However, save for the rear exhaust, none of the facets of the exterior make you question the unit. That said, when we move to the interior of the unit we find a few more things that make it clear that this is not a high end product. While the topology employed is not ancient it has not been, necessarily, one of the best performing topologies we have seen the last few years. The component selection features standard electrolytics from Teapo and solid capacitors from CapXon which is not the best. The actual integration is a bit mixed with examples of great soldering and then some examples of components that are not so meticulously mounted. Lastly, the unit is cooled by a "custom" Yate Loon fan which is probably what is going to get most people's attention on account of the fact that the company name on today's Pure Power 10 600W is "be quiet!." Let’s move on now to the load testing and see how this unit does there!
