850W Power Supplies

↪ 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.

↪ Notes: Though a sleeve bearing fan is used, 1st Player backs it up with a 7-year warranty.

↪ Notes: Although OCP is set reasonably (118% on 12V), the platform is at its limit and cannot handle the increased stress, as ripple gets out of control.

↪ Notes: Shares the same layout as the Lian Li SP850, which, due to its capacity and layout, had a potential fire risk under 100VAC input.

↪ Notes: Detiered only due to specified input voltage. Good performance otherwise.

↪ Notes: Costdown Core Reactor II

↪ Notes: ATX 3.0 refresh

↪ 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: Read note regarding input range. Despite markings on the DC-DC daughterboard indicating CWT GPU, internal shots confirm CWT GPX.

↪ Notes: Read note regarding input range. Mid quality fan; Same Martech "FDB" fan on the MSI A-GL series.

↪ Notes: No OTP claimed

↪ Notes: No OTP claimed

↪ Notes: Claims APFC, "90+" badge, extremely low 12V output relative to total, as is per usual for terrible PSUs

↪ Notes: Updated M5+

↪ Notes: 2 850W samples died in testing during OPP/OCP evaluation.

↪ Notes: Questionable fan choice, claimed as FDB, model was noted as rifle in a review of another PSU.

↪ Notes: Sleeve bearing fan. 12V-2x6 is fixed.

↪ Notes: 12V-2x6 connector (GPU side) has thermistors to act as an "OTP". Stellar ripple suppression, especially on the minor rails.

↪ Notes: Excellent electrical performance, component quality, and noise profile. 12V-2x6 connector has thermistors to act as an "OTP", optional "5V Boost."

↪ Notes: The 5VSB OCP triggering point allows for excessive ripple. Ripple exceeds requirements for tier A under crossload, 100% load, and 110% overload.

↪ Notes: Poor 3.3V transient response, good ripple suppression.

↪ Notes: 650W has poor 3.3V transient response

↪ Notes: Ball bearing fan, 8 year warranty. Cybenetics Gold under 120VAC and Platinum under 230VAC.

↪ Notes: 5VSB OCP set high, poor 3.3V transient response in the 200% excursion

↪ Notes: 2 year warranty; No OTP claimed, but platform is otherwise reasonably capable.

↪ Notes: 2 year warranty; platform is otherwise reasonably capable.

↪ Notes: Bridgeless PFC, OCP needs tuning on all rails

↪ Notes: Excellent noise profile.

↪ Notes: Bridgeless PFC, very high component and build quality. OCP needs tuning on all rails. Excellent noise profile.

↪ Notes: First be quiet! PSU with semi-passive operation.

↪ Notes: Good build and component quality, with good ripple suppression and a decent noise profile. Notably, Aris received a PPG-C sample with a higher capacitance bulk capacitor, different from what other reviews had. PPG-C and PPG-S are identical aside from modularity.

↪ Notes: Platform is well reviewed although no direct transient response data.

↪ Notes: Semi-digital

↪ 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: 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.

↪ Notes: Electrical performance is decent (although no transient response data) but simply not recommendable due to age.
