PSU Tier ListTaken 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. 1200w) Dark Power Pro P11 850w FSP Corsair AX / AXi series 760w .1200w Seasonic (AX) / Flextronics (AXi) AX1500i Flextronics HXi Channel Well Technology RMi Channel Well Technology RM1000x Channel Well Technology Cooler Master V series / V series 1200w Seasonic EVGA SuperNova G2 / P2 / T2 Super Flower Supernova GS Seasonic Supernova GQ FSP Supernova PS Seasonic Enermax DigiFanless 500w Channel Well Technology Firepower Silencer MK3 1200w Super Flower FSP Aurum PT FSP Hydro G FSP LEPA G1600 Enermax Seasonic Platinum series Seasonic Snow Silent 1050w Seasonic X series / X series XM2 Seasonic Silverstone Nightjar Platinum 520w Seasonic Super Flower Leadex Gold / Platinum / Titanium Super Flower Golden King Super Flower Golden Silent / 430w Super Flower Thermaltake .Antec High Current Pro Platinum Delta Electronics Be Quiet Dark Power Pro P10 / 850w FSP (550w .750w) / Seasonic (850w .
