Why bronze efficiency still expensive? what best 400watt under 50$?
650watt bronze efficiency for 100$++
500watt bronze efficiency for 70$++ why most of people keeps recommend a 500watt PSU or 600watt PSU while most of new generation CPU can play 1080p resolution just fine, with loads power under 350watts and idle under 150watts why good 400watt PSU > 50$? Nexus VALUE 430 430W Active PFC Quiet Power Supply priced 60$ Rosewill CAPSTONE Series CAPSTONE-450 450W 65$ still not the right time to recommend a 400watt under 50$ PSU for gamer?

That is extremely dependent on where you live and what options are available to you.

As Raf said, it depends on where you're at and what's available.
In Europe, PSU prices are generally higher than the US; but they get the benefit of having some top-tier units being available at more a budget price due to some OEM's selling direct (ala FSP & Super Flower.) In the US, you can get certain high efficiency units fairly cheaper (like Sparkle/SPI 500w/600w Silver units for under $100 or Aurum 400w/500w.) Though, these unit's are generally of the "underwhelming" designs. Rosewill's Capstone series is an exception to this though. On the other hand, when you're buying your 650w bronze unit for $100 you're buying some top-tier tech. Usually something based on a newer design with Synchronous Rectification on the secondary & utilizing DC-DC converters. The bonus to this is that the 10%-80% efficiency on these units is generally higher than what 80+ requires, by a good margin. Their full-load efficiency is generally where you go down to the 82-83% efficiency level. If you read over at HardOCP or do the math yourself though, a 1000w Bronze unit vs 1000w Gold unit at full load (82% vs 86% or 1219w vs 1149w) you'll notice that when this is converted into dollar values, you're not really saving much on a day to day basis. More so, that full load statistic is very unrealistic for most systems unless you built a system that is going to be running a distributed computing application 24/7 without stopping. Numerically the difference in watts used (or efficiency) may seem to be rather dramatic; but when you convert that into a figure it becomes far less dramatic. On the other hand, efficiency can play a big roll in some other regards. More efficient units kick off less heat and thus do not cause as much of a heat buildup in your room. This can be a bigger difference if you're going from 80+ Standard (or slightly older even) larger capacity unit to something like an 80+ Bronze guy. Just due to the fact that many of the early units certified 80+ Standard did not have as impressive of an efficiency curve in the 20% to 80% range. Like wise, these newer 80+ Gold / Platinum units offer fanless operation & quieter operations due to the lower amounts of heat produced. At the end of the day it all depends on the market & what's available to you though.

Where are you exactly?.. I'd guess one of the Baltic states?
The VP550P(the only version sold in Europe) is the best unit in that list, the SS-400ES comes in second.

As Sin said; VP550P would be the best option on that list. By far it's the best built, it's also relatively quiet & performs very well.
Though, you might be able to find the VP350P in your area as well, and it's worth a consideration as well.

 ...VP350P would have been a great choice too, but since the Asian versions of these units come with no PFC I'd say just get the Seasonic and be done with it Or you could link the shops you're buying from and let us have a look at everything...
