The System Power 10 750 looks like a big step backward. I used to suggest the System Power (U)9 units to users wanting affordable and reliable PSUs with a high performance per price ratio, but this is not the case for the System Power 10 models. The aged HEC platform cannot match the competition despite the pair of upgrades that it received. I had to try hard to find some good things about this product, while on the contrary, I pulled out a laundry list of cons. With competing offerings like the XPG Pylon 750 and the Thermaltake Smart BM2 750, the System Power 10 with similar capacity doesn't stand a chance. With a few dollars more, you can also get the Corsair CX750M which is also far away in overall performance.

be quiet! needs to rethink the whole System Power 10 concept and replace it with something better, as soon as possible, at least the models with up to 750 W capacity which use this terrible HEC platform. There are so many things that need improving, starting with the Yate Loon fan. The XPG Pylon 750 uses a Hong Hua fluid dynamic fan, but be quiet! went with a cheap sleeve-bearing one from a low-end brand. I'm curious how they felt comfortable enough to increase the provided warranty from three to five years, using this fan and the Teapo SC caps on the secondary side. The 200-240 V input range helps the platform get less stress, which is why the single bridge rectifier isn't bolted to a heatsink. HEC also tried to increase efficiency through this trick since the hotter the diodes get, the lower the voltage drop on them. As a professional PSU reviewer, though, I don't feel comfortable seeing an 8 A bridge rectifier in the air without a proper heatsink attached to it. I am not in the position to torture test PSUs, for the moment at least, but I am not sure if this one could stand five years of abuse under 40 °C or higher operating temperatures.
