↪ Notes: 5 year warranty, OCP is set way higher than necessary on the minor rails.
↪ Notes: Insane 7 year warranty given the component quality, OCP is set way higher than necessary on the minor rails, very poor 200% excursion response.
Cuprum Strike (CSK) "DC"
DC-DC
XWY
A11 (HKC ATX-41B clone)
↪ Notes: DC-DC variant of the CSK Bronze; only 750W has 300W 12VHPWR.
↪ Notes: No inrush protection. Sold in the US as Earthwatts Green. 650W utilizes 105C secondary caps, 550W 85C.
↪ Notes: 2 year warranty. PSAZ Bronze w/ARGB fan. 540W, 648W, & 744W on 12V respectively.
↪ Notes: Cost-down full input new PSAZ Bronze w/ ARGB fan.
↪ Notes: 2 year warranty. 550W: 540W on 12V, 650W: 648W on 12V, 750W: 744W on 12V.
↪ Notes: Cost-down full input new PSAZ Bronze.
↪ Notes: Sleeve bearing fan, during OPP testing at around 30% of the 500W model do the minor rail falls out of ATX specification.
↪ Notes: Platform is somewhat mediocre, no direct transient response testing available and not the best choice of capacitors.
↪ Notes: "90% 230V only", claims meeting 80+ Gold without certifying. No direct transient response testing but platform is well reviewed.
↪ Notes: Receives a "-" subtier due to its age. Only kept for legacy purposes as it is still listed on Chieftec's website.
↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.
↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.
↪ Notes: OPP is functional but offers only a 7% increase over the nominal value, beyond which the rails fall out of ATX spec for the 1000W model.
MWE V3 ATX 3.1 Bronze 230V
DC-DC
Gospower
G1208 upd. to ATX 3.1
↪ Notes: Basically G1208 updated to ATX 3.1; broke during 5V SCP. Possible bad sample? No 12VHPWR.
↪ Notes: Green "CX" lettering on black label. Tier should not preclude the usual caveats associated with used/very old power supplies.
↪ Notes: Green "CX" lettering on black label. Detiered to C- due to age.
↪ Notes: Mediocre quality capacitors.
↪ Notes: Low component quality, w/ highly set OCP/OPP & OOS 3.3V transient response. Not quite ATX 3.X by failing low load efficiency. 600W 12+2 cable.
↪ Notes: Subpar component quality, with poorly tuned protections, 5V OCP incorrectly set allows for >135mV of ripple. OOS 3.3V transient response.
↪ Notes: Single EPS cable, failing or near failing 3.3V transient response, hold-up time not within ATX specifications.
↪ Notes: Same internals as the Revobron, simply a 2.0 refresh.
↪ Notes: 850W uses ARGB fan + housing and comes in black and white models. 3 year warranty.
↪ Notes: No OCP on 12V. High RMA rate due to MLCC cracks, similar to other HEC-built EVGA PSUs
↪ Notes: OCP on 12V doesnt exist. OPP is set too high. Sleeve bearing fan.
↪ Notes: Died after OPP testing. OTP claimed but not tested. Sleeve bearing fan. Failed 3.3V transient testing
↪ Notes: No performance data although the platform is decently reviewed.
↪ Notes: Naming scheme is +50W from the advertised 12V wattage. Numerous minor issues, very loud, and OCP is set way too high on the minor rails.
↪ Notes: Actual 12V line output is 50 watts less than the model name (despite being DC-DC), numerous minute issues; overall suboptimal quality.
↪ Notes: Protections need serious tuning; abundant amount of minute issues
↪ Notes: Platform is GPN (or at least very similar), even though the model number indicates it to be GPK.
↪ Notes: Single-rail. See review. Poor transient response on 3.3V, rifle bearing fan. OTP isn't claimed or tested, but is supported by the supervisor IC.
↪ Notes: OCP triggering points on the 5V and 5VSB rails allow for excessive ripple beyond the ATX specification. 5 year warranty.
↪ Notes: Not suitable for use with high ambient temperatures over 40C/~100F, as the fan cannot keep up with the cooling demand.
↪ Notes: Claims LLC resonant, internal shots show otherwise. Parts selection is very questionable and transient response on the minor rails failed.
↪ Notes: Presumably the modular variant of the Thor V3.
