The fresh SilentNight-500 unit from Rosewill is based on Super Flower's trusty Platinum platform, which, although it has already been in production for a couple years, still manages to offer high performance. The competition nowadays is, that having been said, much stronger since their units are based on newly designed platforms that utilize cutting-edge technology for ground-breaking performance. Its direct competitor, as if that weren't enough, is the mighty Seasonic SS-510FL: it sports the same price and features a smaller footprint along with a fully modular design, which makes things even tougher on the SilenNight-500. Rosewill's offering does, however, have an ace up its sleeve with the support of up to four PCIe connectors since its Seasonic rival only comes with two such connectors out of the box. This is a key difference for users who want to install two VGAs with double PCIe sockets each.

To wrap up, although the SilentNight-500 is a great performer offering many interesting features, it still costs a significant amount of money, and its price is higher than its direct competitor: the Seasonic SS-520FL which is based on a fresh platform that manages to outperform Super Flower's design, especially in voltage regulation performance. However, the Seasonic unit only offers two PCIe connectors out of the box, while the SilentNight-500 comes with four, which is something many users will prefer since it will give them the ability to power two VGAs without giving up the silence only a passive PSU can provide; that is, with correspondingly quiet system components. I do think that the SilentNight-500 would be far more competitive with a price tag closer to $120-$130, which would give it a significant price/performance boost that would allow it to claim a bigger market share and a recommendation from me. It, as of right now, does, with the current price tag has a rough road to follow.
