Tier B- Power Supplies

↪ Notes: Decent electrical performance, although some components are of questionable quality.

↪ Notes: Despite markings on the DC-DC daughterboard indicating CWT GPU, internal shots confirm CWT GPX.

↪ Notes: The OCP trggering point for the 5VSB line allows for extremely excessive ripple.

↪ Notes: The OCP trggering point for the 5VSB line allows for extremely excessive ripple. 12V line voltage ripple spikes around the 80-90% load range.

↪ Notes: Ball bearing fan. No warranty period mentioned, detier to B-.

↪ Notes: Non modular variant of the Pure Power 10 CM, virtually identical.

↪ Notes: Weak 3.3V transient response, mediocre electrical performance, and claimed rifle bearing but yet to be proven.

↪ Notes: Both EPS connectors share a cable, poor regulation and transient response on minor rails; only a 2 year warranty.

↪ Notes: A few samples of the base platform died when subjected to sub-90VAC stress tests per JonnyGuru. Proceed with caution under 120VAC, especially in areas prone to brownouts.

↪ Notes: Decent electrical performance but OTP is either not present or set too high (>200°C ) which is useless. See testing here. 2 year warranty.

↪ Notes: Fundamentally a Polaris ATX 3.0 refresh. Load regulation is somewhat subpar on the 1050W model.

↪ Notes: 230V input only

↪ Notes: Poor ripple suppression on the minor rails. Uses semi-digital PFC, 7 year warranty. Can get loud (in excess of 40dbA) under heavy load.

↪ Notes: SI model for Chinese market

↪ Notes: Protections are found to be working in GPW based units in similar or identical configurations.

↪ Notes: Can come in white variants. Protections need tuning. ATX 3.0 refresh of the PM-D.

↪ Notes: Not suggested for use in <120VAC in areas with frequent brownouts. Very poor 3.3V transient response.

↪ Notes: OCP is set way too high on the minor rails, which led to failure of the unit during Aris' testing. Detier to B- unless verified fixed.

↪ Notes: The OCP and OPP triggering points are set way too high on all rails.

↪ Notes: See notes under Series name for how to identify each version.

↪ Notes: High RMA rate due to MLCC cracks, similar to other HEC-built EVGA PSUs. Showed up on B-Stock in huge quantities for dirt cheap c. 2022.

↪ Notes: PWR_OK signal doesn't function correctly. Poor transient response on the minor rails.

↪ Notes: Out of ATX spec ripple on 3.3V rail, fails 80+ Gold efficiency spec,

↪ Notes: Good electrical performance, but lacks or has improperly tuned OTP. No 12VHPWR.

↪ Notes: Not suggested for use under 120VAC if you live in an area with frequent brownouts (see note under input range.)

↪ Notes: Traditional thin circular fan grille.

↪ Notes: No external visual difference, PCB underwent slight revision, poor 3.3v transient response.

↪ Notes: OTP is claimed but has been hit-or-miss on NO-810 units and not present on the P125. Tier is based on other NO-810 units until tested.

↪ Notes: White 750W available.

↪ Notes: Modular board protudes from the unit

↪ Notes: OTP is set over >200C (doesn't function as intended). 850/1000W might not be similar to the 1200W.

↪ Notes: 1 year warranty according to manufacturer, at least in Russia, which appears to be the main target market for this unit.

↪ Notes: SAMA increased the power-good signal's hold-up time by a lot, which makes this PSU a possible danger to hardware.

↪ Notes: Internal shots confirm a costdown Core GC/Focus

↪ Notes: Good electrical performance and decent component quality, however OCP on the minor rails is set way too high, particularly on 5VSB (over 200%)

↪ Notes: Malfunctioning OTP per Aris' testing

↪ Notes: Relatively loud at over 40dbA at full load. Rifle bearing fan.

↪ Notes: Claims an ICB fan, actually uses an LLS (rifle) bearing. Extremely loud, in excess of 45dBA under full load.

↪ Notes: Claims an ICB fan, actually uses an LLS (rifle) bearing. Extremely loud (~40dBA); OPP is set way higher than necessary, as is OCP on 12V, 3.3V, 5VSB.

↪ Notes: Claims an ICB fan, Aris showed a rifle bearing. OPP set high (~150%,) OOS 3.3V transients. Noisy (>50dBA@750W load). Dual EPS on 18AWG cable.

↪ Notes: Claims an ICB fan, actually uses an LLS (rifle) bearing. Extremely loud at ~40dBA for 750W and in excess of 48dBA for the 850W under full load.

↪ Notes: A few samples of the base platform died when subjected to sub-90VAC stress tests per JonnyGuru. Proceed with caution under 120VAC, especially in areas prone to brownouts.

↪ Notes: Two samples (same platform) no longer operated after protections testing per LTT Labs, which is not ideal, but all protections did function.

↪ Notes: Very poor transient response and ripple on 3.3V.

↪ Notes: Bad power good signal.

↪ Notes: Cybenetics report says 650W and 850W units died in -12V SCP testing, which is no longer used in modern systems. 750W unsubmitted.

↪ Notes: Unnanounced OEM swap. Technically invalid 80 Plus certification, but did qualify for Gold in testing, as advertised.

↪ Notes: Single-sided PCB, voltage drops right before protection trip points on the minor rails; however, the protections did engage in time.

↪ Notes: OTP doesn't work

↪ Notes: OTP is set over 200C or doesn't work.

↪ Notes: Limited special edition model for 25th anniversary, no indication of any internal changes

↪ Notes: Very beefy platform, however OTP doesn't work; very loud. Would be tier A- if not for OTP not working.

↪ Notes: Mediocre transient response on the minor rails. The OPP and OCP triggering points should be reduced, as they are set way higher than necessary.
