![]() ![]() ![]() For less than $100 each I'm set for nearly a decade.ĬPU and gfx card now that affects fps and is over $1000, actually the most important part to me. PSU and MB are insignificant to me and I can blindly pick one by reviewing user comments from newegg in about 5 min, and it will last for years. I disagree with the importance you place on this and all of the references you made to this being crucial knowledge. I can't even read all of the chapter titles in this article. We are listing only the popular cap brands that are usually found in low-cost PSUs, but we are well aware that many other low-cost cap brands exist and there is a good chance that you'll find them in non-branded PSU, and even in some branded units.ġ6589602 said: I'm glad there are people dedicated to this but I'm not. When you see one of these brands in a contemporary PSU, you’ll know that the manufacturer set lower-cost production as a priority instead of reliability over time. This group includes the rest of the capacitor brands. These third-tier capacitors, according to information from various PSU manufacturers and people with knowledge of RMA statistics, along with our own experiences with caps, might not be among the best choices, but are still a grade above the caps that belong to the last category. SamXon (except GF series which belongs to a lower Tier).These caps perform well, so they are usually used in mid-level PSUs and sometimes even in high-end units, and they strike a balance between good performance and affordable prices. On this list you will find capacitors made by some of the Taiwanese manufacturers, which often use factories in China. Illinois Capacitor (Currently owned my Cornell Dubilier).Probably we won't meet any of the below cap brands inside a consumer grade PSU, at least their electrolytic offerings, but we decided that it still worth mentioning them. FPCAP or Functional Polymer Capacitor (ex-Fujitsu caps segment, which was bought by Nichicon)īesides Japanese manufacturers there are also several US and European vendors that make high-quality capacitors.And since the reforming process takes time and equipment, production costs are further affected.Īll Japanese caps are considered of high quality, and we like to see the following cap brands: In many cases, they need reforming before use in order to avoid operating problems. If the recommended storage period is exceeded, the capacitors need to be checked one-by-one (including ESR and capacity measurements). Electrolytic caps should be stored under specific conditions in order to retain their electrolytes, and especially for use in SMPS units, their storage period cannot exceed a specific threshold. The situation becomes even worse when you consider that you cannot order huge quantities of Japanese caps, store them for a prolonged period and then use them, since their performance will be greatly affected. Chinese cap companies can offer larger quantities, and if we take into account that in most high-end PSUs only Japanese caps are used, then it is more likely for availability problems to occur with Japanese caps. Of course, it is still much easier for Chinese PSU companies to acquire caps made by a Chinese factory. However, we believe enough Japanese companies have manufacturing facilities in China (along with many Taiwanese manufacturers), so the problem might not be as significant in some cases. Most PSU factories are located in China, so they have to import the capacitors from Japan, requiring additional time and shipping costs. However, there are two problems with using Japanese-made caps: their cost is higher and sometimes there are availability problems.
