 What's up internet? Maraming specs and terms yung PSU, but basically you're just looking for one thing in any power supply unit. Is it reliable? Maasahan mo ba siya? Be Quiet System Power U9 is an entry-level PSU and it is that reliable. First things first, Be Quiet sent us this item for review but had no say in what we had to say about it. This is an 80-plus rated bronze PSU and I've talked about in previous videos why 80-plus certification is important and why in general 80-plus rated PSUs are more reliable than unrated ones. Here at the shop, we generally recommend bronze as the minimum level for any build. Interestingly, this PSU has two 12-volt rails. A couple of years ago, naging uso for high-end PSUs to have multi-12-volt rails. Medyo na wala na siya sa uso and it's very uncommon to find it in an entry-level PSU. While the benefits of a multi-rail PSU have been endlessly debated online, the general consensus is it does add a degree of protection to your hardware. Aside from having two 12-volt rails, the System Power U9 also comes with a variety of safety features, the most important of which might be OCP or overcurrent protection. Basically, if there's a surge of current, the System Power U9 will make sure that all of that excess current won't get dumped onto or into or through your expensive PC components. It stops it at the PSU level. It also has built-in protection for overvoltages, undervoltages, short circuits, overloads, and overheating. As this is a be quiet product, they care about the noise that it generates. The major moving part of any PSU is the fan and this one is temperature-controlled. In other words, there's a baked-in fan curve where the speed of the fan changes depending on the temperature of the PSU. Bit uncommon again to see this in an entry-level PSU and I'm glad to see this kind of practice trickling down and becoming more mainstream. On aesthetics, this is a non-modular PSU. I think modularity might be too much to ask for at this price point. The cables, though, at least look good with some of them being sleeved or mesh type and some of the other cables being the flat plastic type. As long as the cables do not look like the ugly spaghetti mess of generic power supplies, then I'm good. Lastly, the System Power U9 does come with a three-year manufacturer warranty. We've used this PSU daily for around six weeks now without any problems. Of course, that's a short length of time, but because of all the features I just mentioned, coupled with the general reliability of the Be Quiet brand, I'm pretty confident in saying that we can run this thing daily for years without any problems.
