1200W Power Supplies

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

↪ Notes: Updated R series

↪ Notes: Due to the platform's limitations, ripple gets fairly high under heavy load but remains within 100mV. OCP is set high 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: Excellent electrical performance, component quality, and noise profile. 12V-2x6 connector has thermistors to act as an "OTP", optional "5V Boost."

↪ 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: 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: 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: Interleaved PFC; digital operation for primary, APFC and 12V; minor rails are analog.

↪ Notes: 85C bulk cap, rifle bearing fan. Good noise profile. The OCP triggering points on the minor rails are set much higher than necessary.

↪ Notes: 3.3V transient response could be better, overall performance is good, alongside a relatively quiet noise profile.

↪ Notes: Semi-digital

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

↪ 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.

↪ 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.

↪ 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: 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: 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: OCP is set sky high on 5VSB.

↪ Notes: The OCP triggering points, while functional, are set much higher than necessary on all rails.
