With low wattage units, noise isn't much of a problem (well, provided you didn't buy the worst chinese brand junk), because fans are temperature regulated and in a bottom mounted case, the PSU simply doesn't get hot enough to cause excessive fan rpm. I use cheap 300-400W units all the time for years. Never had noise issues from them and even overclocked to 4.5Ghz on Corsair VS350 (although i wouldn't do that on daily basis). Granted, usually my typical max load is something like 220W or less.

That's great price. Here the best price for that is 46 euros, while the average is above 50 €. Despite gamers loathe anything cheap, if you don't have high wattage demands and keep max load 80% of max wattage, cheap PSUs are actually doing fine. After 5 years i usually check the capacitors and then once a year. Usually change them in 5 or 7 years though. Never had problems. I 've only had problems with 2 PSUs. 1 Seasonic (Corsair CX400) failing after 5 years and another Seasonic (XFX) that has terrible coil whine and don't use it. The problems with cheap become evident, when you go to high wattage or with some extra crappy PSUs with claims for high wattage and/or fake protections. Of course something else to consider is that it can be an overclocking limit, but like i said, i 've done 4.5Ghz on VS350 as well as EVGA 430W (both considered blasphemy here), so if you are not after records, they do fine. I 've been pounding PSUs of that category with x264 (or XVid before) for years for hours and hours and never had issues. Bottom mounted PSUs are a bliss for the PSU capacitors, provided that you clean the PSU filter from time to time. Edited by Undervolter - 1/30/16 at 2:15pm
