May I ask why you consider Masterwatt lite to be a bad product ? Did you even read the review ?
sure.. no problem bro
AFAIK
i'll talk about VP650P/VP550P
Antec VP550P , VP650P and VP650PM are much better products than Masterwatt lite...
whereas Masterwatt lite is much better than Antec VP450P, VP500PC, VP600P ,( these are made by FSP and CWT and uses bad caps Capxons etc )
Components - Antec VP 550/650 uses Japanese + solid capacitors on 12v rail .. 12v rail is the most important rail,90-95 % system runs on this rail, as CPU and GPU take power from this rail , whereas Masterwatt is using Teapo . which is mediocre .. while ripple at 100 % load is high with Antec VP , but in this review it wasn't tested at 70-80 % load which is much more realistic and practical . and is much lower in that from other similar reviews with delta units iirc.. at 100 % these Delta units and most PSU's don't behave well .. and mos people don't load their PSU to 100 %
example in this..
PC 리뷰 - Antec VP650PM 모듈러
20 % load- 26mv
50% - 26mv
70 % - 30mv
100 % - 70mv
But having Japanese capacitors means ripple will not increase over time , but with Teapo there , as capacitors age , Teapo is likely going to have higher ripple over time after 4 years or so if they don't fail by that time already.. although Enhance is also good OEM ( Masterwatt lite OEM )
primary cap Samxon is better brand ( except GF series ) and also rated at 450v .. whereas Teapo is 400v which is minimum for a primary cap.. though both should be fine as primary fail less unless these are bad caps compared to secondaries
you can search abut capacitors on badcaps.net forum
Rest of the Caps Generally--- Samxon(except GF )> Taicon > Teapo> Ltec/Suscon but...
and the other main reason -This power supply is made by Delta (Excellent and Largest PSU maker , ) .. Only Delta is famous for designing it's PSU in such a way where even low grade caps last long , while the exact same Caps fail for everyone else far more .. Source - badcaps.net forum .. So this PSU is good for 5 years with gaming PC
and i think the PCB problem in that review shouldn't be a concern in it's normal functioning ..
While Corsair new CWT made 2017 CX non modular is better than both VP550p and masterwatt lite.. And TXM better than Seasonic S12ii and all other PSU in that range..
