Below are a number of non-interesting power supplies which are often popular. These power supplies are usually not as bad like the ones above, but are just too expensive for what you get. The largest profit is in the budget and mainstream segment and not in the high-end segment. If you have good high-end products and focus on marketing, a non-interesting budget power supply also sells much better. This is because the average consumer would rather buy an over-priced, poor-quality power supply from a well-known manufacturer than a power supply with an excellent price, performance and quality ratio from a less-known manufacturer.
Take for example a manufacturer like EVGA who currently has power supplies that cost less than 100 euros, but these power supplies are not very interesting. Quality and performance are only moderate and the price is much too high. However, these power supplies do sell well due to the name recognition of EVGA and the good SuperNOVA G2, P2 and T2 power supplies. Corsair has also had non-interesting power supplies below 100 euros for few years, but that has come to an end with the Vengeance and new CXM series. Still the old CXM series, CX series, CSM series and RM series sold very good due to the good name that Corsair had.
You should not use low-end power supplies such as the
Corsair VS series and
Cooler Master B v2 series for a new PC. The quality and performance of these power supplies are very poor, so that the expected lifespan is short. These are power supplies intended for repairing an old PC, so that it can last for two years and will get replaced after. The price / quality ratio is often hard to find with such power supplies. They may be cheap, but for a few more euros you can get something much better, so you can better ignore power supplies such as these.

The old
Corsair CX Bronze and
CX Modular are two popular series. But these power supplies actually have nothing special. They do not have a DC-DC or other form of individual voltage regulation (at least up to 600W), but group regulation does not have a good voltage stability and also no high efficiency. The quality of this series does not go much further than moderate. Such a power supply therefore requires a low price. However, the price of these series is relatively high, which means there are better options. The 750W version also has DC-DC, but is also not good, the price is therefore too high. The price is comparable to a number of high-end 750W power supplies. The successors of these power supplies are a lot more interesting, which are therefore mentioned below.
The two cheapest EVGA series, the 80PLUS and 80PLUS Bronze series (both of which are fairly nameless), are also not really products that you should consider. Just like the Corsair CX (M) series up to 600W, they are based on a double forward design with group regulation. This is an outdated design without individual voltage regulation and therefore no support for the C6 and C7 power states. But the overall performance is also just poor. In addition, the quality of the power supplies is not too high and the price is high.
The be quiet! System Power 7 450 to 700W is based on the FSP Raider platform and have an 80PLUS Silver certificate. FSP Raider is known for its poor performance, even though the efficiency is higher than an 80PLUS Bronze power supply at a comparable price. That does not make these power supplies a better choice. The problem with this series is that they have group regulation and that the voltage stability is very poor, this also applies to the ripple suppression and the quality is nothing special either. All this makes that you can look better power supplies with less high efficiency and therefore an 80PLUS Bronze certificate than this. In addition, if you have a PC that needs 450W or more, you probably have a high-end game PC and you shouldn't look for a low-end power supply anyway.
The be quiet! System Power 8 series is the successor of the System Power 7 series. The System Power 8 series currently consists of three power supplies, but none of them are really special or really worth considering. The quality and performance have not improved compared to the previous generation, the only advantage could be the black cables. But PCs that require a 500W or 600W power supply and are therefore a high-end game PC simply deserve a much better power supply than this budget series. You might want to consider the 400W version, but it is smarter to simply spend a few euros more. These power supplies also do not have individual voltage regulation and are therefore not C6 and C7 compatible.
