Is your computer resetting?
Or maybe it won't turn on?
Your computer shuts down while gaming?
Perhaps the power supply is to blame!
I present the blacklist of power supplies .
Achieve, Akyga Basic, Altis, Aspire, Atlas, Aton, Bandit, Bestec, Carbon ( not Modecom ), Coba, Codegen, ColorSit, Computer, Cube Max, Deer, Delux, Eurocase, Everpower, Feel, Fever, Four Star, Gembird, Gigabyte, GoodWatt, Hawk, Hedy, Impet, Incore, Intex-Action, i-box, I-TEC, KingStar, Levicom, Likeenergy, Linkword, L&C, Logic, LOGISYS, Macron, Megabyte, Mercury, Metropilis, Modecom Feel, Mustang, Newton Power, Pangu, Platin Power, Power, Power Color, Powercomp, Powerfox, Powertec, Procase, Procomp, Octigen, Opengate, Qoltec, QTECHNOLOGY, Q-tec, RAIDMAX, Rebeltec, Rubikon, Ropla, Sansun, SilenX, Sun Pro, Suntek, Take Me, Task, TE, Tracer, Tronje, Ultra Media, V Power, Whitenergy, Win, Xilence ( produced up to and including 2011 ), XION, X-Power, 2N .
Few people realise when buying a computer how important a power supply is. It determines whether all components get the right voltage and the stability of the whole set-up depends on it.
If you have one of these power supplies, you will need to replace it. These power supplies, although they may have astronomical wattages on their stickers, 'give away' very little! But this is not the only indication of their 'cheapness'. During a failure of such a power supply, several other components are usually damaged, e.g. the hard disk drive, the motherboard, the processor, and in the worst cases, everything. Of course, there are cases where nothing 'dies' after a failure of such a power supply. Sometimes it happens that such power supplies work faultlessly for many years - but these are really exceptions! These power supplies are often the reason for the instability of the entire computer. Obviously, if you are faced with the choice of a power supply unit - do not under any circumstances buy one of these!
It can be said that these power supplies (if you can call them that...) consist of a board, a transformer, 3 capacitors, a fan and 2 pieces of aluminium.
Just to illustrate, I will add 2 pictures: the first one shows the power supply in question, and the second one shows the real power supply. .

A real power supply...:
.
At first glance you can see the difference between the power supplies. Additionally, the performance of a 450W 'power supply' from a blacklisted brand differs significantly from that of a branded 450W power supply.
Additionally, please see what 'chokes' are used in power supplies from the above manufacturers (photo from a disassembled Take Me 400 power supply): .

As you know (or not) a choke is a coil wound on a core... I don't think a longer comment is needed? But if anyone still doesn't believe: https://www.elektroda.pl/rtvforum/topic1983518.html

Deer "brand" power supply. Symptoms? Smoke, stench and sparks.
Further outbreak: .
Feel power supply.
There was almost a fire. It was only due to the fact that the user was at home, smelled the stench and smoke coming from under the desk, quickly disconnected the power supply and put the computer out on the balcony to extinguish.

// Update gulson 06 Feb 2020 - swapped Akyga for Akyga Basic, due to Akyga also producing other versions of power supplies like PRO or Ultimate. Distributor notification dated 21 January 2020, ticket #678965 .
/ I have updated the information provided to me by colleagues:
Hephaestus, Saturday, Yansen. I have moved the posts where 1-2 power supply models were added to the bin. It's easier to find your way around in one post than to read a multi-post thread.
