↪ Notes: OCP is set way higher than necessary on the 12V and 5VSB rails. Good noise profile given its capacity.
↪ Notes: Not to be confused with the Xigmatek Loki.
↪ 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: OPP is set way higher than necessary and isn't reduced even under high operating temperatures. Very poor 200% excursion response.
↪ Notes: Multitude of minor issues leading to low overall performance, does not meet requirements for tier A in Aris' testing. Possible bad sample?
↪ Notes: Not to be confused with the downgraded non-modular Pure Power 12!
↪ Notes: Bridgeless PFC, very high component and build quality. OCP needs tuning on all rails. Excellent noise profile.
↪ Notes: Interleaved PFC; digital operation for primary, APFC and 12V; minor rails are analog.
↪ Notes: Semi-digital
↪ Notes: Extremely high build quality; made in Japan; decent performance.
GX III Gold ATX 3.1
DC-DC
Lite-on
Custom, but different from ^
↪ Notes: Has purple heatsinks for glam. Loose load regulation on 5VSB rail with middling 12V excursion response.
↪ Notes: Blue label. Tiering is based on electrical performance and should not preclude the usual caveats if buying used power supplies.
↪ Notes: Modular inputs on side of PSU rather than the rear. Use caution and check case clearances: see Jon Gerow's list of cases (archive)
↪ Notes: Gray label. Per-connector 40A OCP when multi rail is enabled
↪ Notes: Refresh with included 12V-2x6 cable and listed ATX 3.1 compliance. Actual design appears to be the same internally.
↪ Notes: Minor changes on the primary side, overall very similar; merely a refresh. Embossed cables instead of flat cables from older generations. (Fancy)
↪ Notes: Black label; China only
↪ Notes: 750/850W: 140mm, 1000/1200W: 150mm. 2023 version includes 12VHPWR cable. Early reports of coil whine and premature failures/DOAs, but supposedly fixed.
↪ Notes: Protections need tuning, 5VSB regulation doesn't quite qualify for A tier.
↪ Notes: 850W model can come in white.
↪ 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: 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: 13 year warranty. 5VSB OCP still allows for extremely excessive ripple. Good performance otherwise.
↪ Notes: Transient response doesn't quite make it A tier, no direct protections testing.
↪ Notes: Solid electrical performance, however let down by poorly modulated protections and mediocre ripple performance.
↪ Notes: 850W has excellent noise graph.
Hydro PTM Pro
DC-DC
FSP
Hydro PTM Pro high-wattage
↪ Notes: One EPS cable with two connections, transient response on the minor rails are very subpar, OCP needs tuning per Aris' testing.
↪ Notes: Identical to the PTM X Pro made for ATX 3.0 compliancy.
Aurum Platinum (PT)
DC-DC
FSP
Aurum Platinum
↪ Notes: Solid electrical performance (A tier) but nothing regarding protections has been tested. B+ until further notice.
↪ Notes: Doesn't claim SCP according to this review.
↪ Notes: Malfunctioning OCP on 3.3V, and transient response on 3.3V is out of spec, questionable choices of components.
↪ Notes: Protections need serious tuning; abundant amount of minute issues
↪ Notes: German bulk caps; dual-chamber L-shape design; modular inputs on the main PCB. 1000W and up models come with a USB/fan hub.
↪ 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: Protections need tuning and mediocre ATX 3.0 transient response; overall performance is dwarfed by the CWT-built Titan Gold.
↪ Notes: Available in black and white
↪ Notes: Dual system. Load regulation on 12V could be better.
↪ Notes: Overall good performance, uses a YL rifle-bearing fan.
↪ Notes: OTP is set over >200C (doesn't function as intended). 850/1000W might not be similar to the 1200W.
↪ Notes: Semi-digital, Razer Chroma integration with other Razer products.
↪ Notes: Very high ripple on the 12V rail for a unit of this caliber.
↪ Notes: Claims OTP but not tested in Aris' review, B+ until further notice.
↪ Notes: While the power supply is rated for 40°C, testing done by Aris (who tests at 45°C), shows excessive ripple above the ATX spec at 110%/CL2 load.
↪ Notes: The OCP and OPP triggering points need tuning. Very good ripple suppression, and decent component quality. Excellent noise profile.
↪ Notes: Failed JonnyGuru's burn-in test (gave up the ghost), protections are poorly misconfigured on this platform.
↪ Notes: Based on the same platform as the Black Hole; OTP untested; some parts remain unidentifiable; white variant available.
↪ Notes: ATX 3.0 transient response could be better. 5VSB OCP is stupidly high.
↪ Notes: OOS transient response on 3.3V. The OCP and OPP triggering points are insane, particularly 5VSB OCP, which is set over 200%. 7 year warranty.
↪ Notes: Very poor transient response and ripple on 3.3V.
↪ Notes: Bad power good signal.
↪ Notes: 1200W hold-up time fails to meet the ATX minimum specification.
↪ Notes: Failed ATX 3.0 12V power excursion testing, malfunctioning OCP on 3.3V. False efficiency certifications.
↪ Notes: Aggressive fan profile, ~40+ dbA output.
↪ Notes: Questionable fan quality, two EPS connectors on the same cable. Otherwise qualifies for A tier based on performance.
↪ Notes: Excellent noise profile despite uncompetitive overall performance. Poor load regulation on the 5VSB rail and poor transient response on 3.3V.
↪ Notes: Quite loud under full load, ~39dbA
↪ Notes:
↪ Notes: Be wary of 2024 OEM/Platform change in the N.A. market!
↪ Notes: OTP works on the 1200W model, however the 5VSB OCP is so out of tune, ripple suppression exceeds 100mV.
