Tier A Power Supplies

↪ Notes: FDB fan; Hong Hua

↪ Notes: Costdown Core Reactor II

↪ Notes: 1000W model has poor transient response on 12V under 200% spike, other models mediocre. 850/1000W avail. in white.

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

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

↪ Notes: FSP-57AZB. 12V-2x6 connector (GPU side) has thermistors to act as an "OTP".

↪ Notes: 650W has poor 3.3V transient response

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

↪ Notes: Not to be confused with the Xigmatek Loki.

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

↪ 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: Much better performance than the 1200W model and fewer issues despite using the same platform.

↪ Notes: Not to be confused with the downgraded non-modular Pure Power 12!

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

↪ Notes: Double-sourced between FSP and HEC. FSP provides the 1200W variant for the US market and HEC supplies it for the European market. Good noise profile and electrical performance. First be quiet! PSU with semi-passive operation.

↪ Notes: Design modified for multiple 12V rails: 3 on ≤550W, 4 on ≥650W

↪ 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: Basically G1278 updated to ATX 3.0

↪ Notes: Still essentially G1278 with further updates to ATX 3.1

↪ Notes: Single/multi-rail switchable.

↪ Notes: Extremely high build quality; made in Japan; decent performance.

↪ Notes: No internal changes, but 1300W only.

↪ Notes: Same platform as SilverStone HELA 2050 Platinum.

↪ Notes: Braided cables, some units manufactured between Oct. 2019 to Mar. 2020 (lot codes 194448xx to 201148xx) recalled for potential failures.

↪ Notes: Standard cables

↪ Notes: v2, 160mm long, doesn't have 1000W version; custom Corsair rifle bearing fan.

↪ Notes: v1, 160mm long

↪ Notes: Blue label. Tiering is based on electrical performance and should not preclude the usual caveats if buying used power supplies.

↪ Notes: v1, 180mm long

↪ Notes: v1, 180mm long, individually sleeved cables; custom Corsair rifle bearing fan.

↪ Notes: v2, 160mm long; custom Corsair rifle bearing fan.

↪ Notes: v1, 180mm long. Production continued far past other 2015 RM-x units as the 2018 revision has no 1kW variant.

↪ Notes: Blue label. Tiering is based on electrical performance and should not preclude the usual caveats if buying used power supplies.

↪ Notes: ATX 3.0 compliant; uses dual 8-pin to 12VHPWR.

↪ Notes: No performance data, however platform is well reviewed with protections working in similar configs.

↪ Notes: OCP originally set way too high; fixed in later reviews from July 2024. Excellent electrical performance. ATX 3.1 and ATX12VO compatible.

↪ Notes: Old but gold (no pun intended.)

↪ Notes: Same internals as the original G2, but with white LEDs (yes, really.)
