2025 Power Supplies

↪ 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.

↪ Notes: OCP is not claimed on any rail (although it most likely exists for the minor rails only), very low +12V line output relative to total capacity.

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

↪ 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: DC-DC variant of the CSK Bronze; only 750W has 300W 12VHPWR.

↪ Notes: OCP is set way higher than necessary on the 12V and 5VSB rails. Good noise profile given its capacity.

↪ Notes: Fan profile is extremely relaxed, OCP is set way too high on the minor rails, no FFP despite being an extremely expensive platform.

↪ Notes: Excellent noise profile.

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

↪ Notes: Excursion response in the 200% test could be better compared to other units in its class. Excellent noise profile.

↪ Notes: 85C bulk caps, excellent noise profile.

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

↪ Notes: Low quality fan, 85C bulk cap.

↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.

↪ Notes: Semi-digital. Good noise profile. 5VSB OCP is set quite high. Look above for case clearance list.

↪ Notes: Minor changes on the primary side, overall very similar; merely a refresh. Embossed cables instead of flat cables from older generations. (Fancy)

↪ 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: 650W has 300W 12V-2x6 cable. Poor 3.3V transient response. All use Hong Hua rifle-bearing fans. Y-shaped fan grille perforations.

↪ Notes: Ripple suppression, while within the limits for tier A, isn't as good as other units in its class. The OCP trip points need to be reduced on all rails.

↪ Notes: Very high inrush current, poorly tuned protections on the minor rails; otherwise decent electrical performance.

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

↪ Notes: Good electrical performance for the category, decent component quality, protections are set reasonably.

↪ Notes: 13 year warranty. 5VSB OCP still allows for extremely excessive ripple. Good performance otherwise.

↪ Notes: ATX 3.1 is claimed, but the unit fails to meet the spec due to poor ATX 3.1 excursion response. Treat as ATX 2.x.

↪ Notes: 850W has excellent noise graph.

↪ Notes: Identical to the ASRock Taichi, however until further testing exists, it will not receive a "+" grade. See teardown here.

↪ Notes: Good electrical performance and reasonably quiet for the category.

↪ Notes: Rotatable power outlet. 5VSB OCP is high. Includes a USB 2.0 hub.

↪ Notes: Excellent performance and noise profile. OPP and OCP on the minor rails need tuning. They do work but are set way higher than necessary.

↪ Notes: OCP is set high on 3.3V and 5VSB, 5VSB voltage regulation >3% at 4.87%, mediocre excursion response in the 200% test. High inrush current.

↪ Notes: Either dual sourced or XWY replaced HKC.

↪ Notes: Semi-digital.

↪ Notes: Only one 8-pin PCIe cable! Dual 12VHPWR. Good performance in pre-production sample, but needs fine-tuning. Semi-digital.

↪ Notes: Minor rails' OCP is set lower compared to the CWT-built high-wattage models. 650W is noisier than the 750W on account of using a DBB fan.

↪ Notes: Extremely quiet operation; however OCP is set high on the minor rails.

↪ Notes: Yate Loon rifle bearing fan. The OCP triggering point for the 5VSB line allows for extremely excessive ripple.

↪ Notes: Yate Loon rifle bearing fan. The OCP triggering point for the 5VSB line allows for extremely excessive ripple.

↪ 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: 130mV+ of ripple on all rails (out of spec) at only 60% load; failed to meet even 80+ Bronze. See Rear Shot and Output Specification Label.

↪ Notes: Excellent noise profile.

↪ Notes: No OCP, faulty UVP on 3.3V, bad electrical performance.

↪ Notes: Overall good performance, uses a YL rifle-bearing fan.

↪ Notes: Globe Fan FDB fan. Assumed to be quite noisy (>48dBA) based on other units on the same platform. OPP is set way higher than necessary.

↪ Notes: Internal shots show the unit using the same "ICB" (in reality rifle bearing) fan as the SilverStone Triton Rx.

↪ Notes: PPFC; bundled with select Rosewill cases.

↪ Notes: The OCP and OPP triggering points need tuning. Very good ripple suppression, and decent component quality. Excellent noise profile.

↪ Notes: Mediocre load regulation on the minor rails, and poor excursion response in the 200% test. The OCP and OPP triggering points are set too high on all rails. 1000W model has high inrush currents. Good performance otherwise.

↪ Notes: Mediocre load regulation on the minor rails, and poor excursion response in the 200% test. The OCP and OPP triggering points are set too high on all rails. 1000W model has high inrush currents. Good performance otherwise.

↪ Notes: Mediocre load regulation on the minor rails, and poor excursion response in the 200% test. The OCP and OPP triggering points are set too high on all rails. 1000W model has high inrush currents. Good performance otherwise.

↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.

↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.

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

↪ Notes: Excellent overall performance, component, and build quality, quietest SFX unit in its class.

↪ 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: 3-year warranty, has A- performance from a multitude of minor issues.

↪ Notes: Interleaved PFC. Good performance, but OPP & 12V OCP allow the unit to exceed the AC receptacle's current rating. OOS 3.3V transients.

↪ Notes: Bridgeless PFC, exceptional electrical performance per Cybenetics' entry & confirmed internal shots per Quasar Zone and Aris.

↪ Notes: Excellent noise profile despite uncompetitive overall performance. Poor load regulation on the 5VSB rail and poor transient response on 3.3V.

↪ Notes: The OCP and OPP triggering points are set much higher than necessary.

↪ 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.

↪ Notes: No OCP, and OVP/UVP is set too high to be effective. Also really only a 600W unit despite being advertised as 750.
