See spreadsheet for changelog, methodology, detailed description of colors, review sources and other info.Ĭheck ‘Units index’ and ‘Changelog’ tabs in the spreadsheet or ask in our Discord if you don’t see some model here. Stock or after manual configuration using software or fan mode switch button. Additionally, for tier A units, sub 35 dBa under 70% load for =>850W units (30-50W load on minor rails), and sub 20 dBa under low load (idle), i.e 100W at 12V rail and 15-20W load on minor rails. Sub 30 dBa under moderate load i.e 300W at 12V rail for 750W units (30-50W load on minor rails). Includes requirements for blue color (quiet operation).įor tiers C & B : mostly based on review availability, objective quality and performance compared to competition in the same tier to highlight the most important models in respective price rangesīlue - Quiet operation. Includes requirements for blue color (quiet operation). Tier C and above - required to have independent regulation on all rails and/or 850W units respectively with 16AWG for PCIe and 18AWG for EPS cables on 12V leads. Tier B and above - required to have OTP (just claimed is enough, but if it's tested and the unit did not survive - detier to LP subtier), to have OPP tested (detier to tier C if failed), be based on ACRF or ZVS primary, DC-DC secondary topology, and have APFC with full VAC input range (100-230V) voltage regulation and ripple should be in spec under 110% overload 12V ripple below 100mV under 110% overload should be rated for continuous operation at minimum 40☌ ambient (not just 'operating conditions' but unless proven to not qualify by testing, only claimed operating conditions without continous operation remark is enough) Minimum 18AWG gauge wires for hot 12V leads on GPU/EPS/ATX cables, on pig-tail cables - at least to the first connector, 20AWG to the second or for ground leads. Tier A - OTP should be tested (if not tested - detier to SP subtier), working and set below 200☌ (if it's set higher - detier to LP subtier), required to be based on ZVS primary topology (LLC or phase shift resonant), have ripple below 50mV under all load situations up-to 110% overload, 30k hours MTBF at 40☌ (generally non-plain-sleeve bearing) or be fanless. Pay attention to rails configuration when using with high power draw components to avoid shutdowns. Multi-rail units - Not necessarily better than single-rail units but provide an extra layer of protection by having 12V OCP set lower than total capacity, which is especially relevant for very high-capacity units (=>1kW). Not recommended for purchase over any normal priority units or even some of the better units from a lower tier. Speculative position subtiers - For units positioned based on very limited info, without proper reviews. Not recommended for purchase over any normal priority units. Low priority subtiers - Units with minor issues (see footnotes). Numbers in red colored square brackets - Footnotes, see descriptions at the end of respective tiers Square brackets - Additional description (wattage range, part of SKU code, label / casing color, release year) Parenthesis / Round brackets - Model variations (which belong to the same position) Underlined - Opens an card with detailed information and links to Amazon Slash - Models (inside one series) separator Hyphen / Dash - Series / lineups separator Includes quiet operation for tier A.īlue highlight - Quiet operation under moderate load Gold highlight - Best units in the tier, proven by professional reviews.
