PSU Tier List
Taken from http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html on 2016-03-22
This list looks at the main and critical sectors of a Power Supply Unit -
Components - Higher quality components means more stable functionality, thus longer life on power supply and
components of PC. Low quality components can affect the life of the unit and all components of your PC.
Stability - A power supply that can output it's wattage and ampere current at a stable temperature and beyond or below
capable with minimal ripple and without shutting down shows that the unit is more than capable of powering any PC
within it's labelled wattage. A power supply that can't must be avoided.
Efficiency - Although not really relevant to the quality or the stability of any power supply, but it can contribute to saving
money on energy bills and can even be close to virtually silent. Perform research on your desired PSU to see if it can
reach its labelled efficiency rating. Link above for more information.
Safety - A power supply must be capable of working without short circuiting or causing any serious harm to you or
others around you if it fails. Perform critical research on your desired PSU to make sure it is safe to use with all safety
switches, such as over-temperature protection included. Stay away from units with close to no safety switches at all, for
the safety of you and others around you.
All PSUs will be colored in co-ordination of the Ecova 80+ efficiency ratings (true efficiency only) below - Standard Bronze Silver Gold Platinum Titanium
Again, all PSUs are researched by reading professional, unbiased reviews with the correct testing equipment. Some units
won't be returning, due to discontinuation and / or too old.
A PSU cleanup is scheduled for Summer - Fall 2016
List updated - February 16th 2016
___________________________________________________________________________ Tier One
The highest quality and most stable Power Supply Units available. Protected by industrial grade protection circuitry and
can output wattage at a rated maximum temperature of 50°C or below. These units are also Haswell certified, meaning
they can cope with the C6 and C7 sleep states of 0.05Amps without triggering the under-current protection switch. May
even go over labelled wattage and still work until it safely shuts down.

Some Haswell compatible, some not (maybe unconfirmed). Still safe to use and stable, just lower quality components.
Not really ideal in serious overclocking or super-high load situations, such as a Bitcoin mining rig or a high end gaming system.

___________________________________________________________________________ Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false
advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For
your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and
could even kill you, let alone your system. A-TOP technology Apevia Apex (SUPERCASE/ALLIED)
