Tier E Power Supplies

↪ Notes: APFC - no 80 Plus or Cybenetics rating

↪ 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: 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: 12VHPWR cable, unknown quality fan (likely sleeve bearing), no claimed OTP. Only teardowns proving platform.

↪ Notes: Pro and Pro RGB Modular are the same internally.

↪ Notes: 1000W model might be DC-DC, unable to confirm without a proper teardown

↪ Notes: Overall very low build quality

↪ Notes: Double-sourced between HEC and Andyson

↪ Notes: Double-sourced between HEC and Andyson

↪ Notes: Also known as CSK[w]H. Not printed on the logos.

↪ Notes: Most likely for the Asian market; sightings in China and India. Ketchup and mustard cables, different fan grille, label, and box.

↪ Notes: X8 might be a clone of CWT's GPK platform, but is similar to the M5 platform (not very good.)

↪ Notes: Very low build quality, basically e-waste

↪ Notes: Group regulated; effective capacity is 10% lower than advertised based on +12V current rating

↪ Notes: Very low overall performance and poor quality control leading to extremely inconsistent results, even on their high-end models. Lower-end models are untested and should also be avoided unless professional reviews are released.

↪ Notes: Fraudulent business practices and review manipulation. Testing from multiple sources has shown performance to be significantly lower than average. Fake 80+ certifications. Significant platform downgrades with the same model number and no difference in branding prevent review data from being useful for making recommendations. Tier E should be considered an upper bound for recommendations; certain models such as the AGV qualify for tier F.

↪ Notes: 2 year warranty. PSAZ Bronze w/ARGB fan. 550W: 492W, 650W: 576W on 12V.

↪ Notes: 2 year warranty. 650W: 576W on 12v.

↪ Notes: Terrible ripple suppression, especially on 12V (well over 100mV under full load), OCP is not set properly, low efficiency, low quality fan.

↪ Notes: Looks exactly the same as the regular System Power 10 internally. Unless later testing proves the above issues are not present, detier to E.

↪ Notes: Voltage regulation is out of ATX specifications on the minor rails; also not independently regulated.

↪ Notes: "85% 230V only", ketchup and mustard cables. Outdated and no official 80+ certification, only on the tier list since it's still on their website.

↪ Notes: "85% 230V only", ketchup and mustard cables. Outdated and no official 80+ certification, only on the tier list since it's still on their website.

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

↪ Notes: "85% 230V only", ketchup and mustard cables. Outdated and no official 80+ certification, only on the tier list since it's still on their website.

↪ Notes: Only basic voltage regulation and ripple data found here. Not recommendable due to age; only kept for legacy purposes (still on website.)

↪ Notes: Not 100% sure on platform

↪ Notes: Basically Elite V4 but full range

↪ Notes: Green "CX" lettering on black label. 85C caps all around, 30C rated operating temp, avoid.

↪ Notes: Green "CX" lettering on black label. 85C caps all around, 30C rated operating temp, avoid.

↪ Notes: Grey label; OCP doesn't work properly, allowing the voltages to fall out of spec, very poor ripple suppression on 5V, failed transient testing on 3.3V

↪ Notes: OEM and platform is unconfirmed, unit is basically e-waste though.

↪ Notes: Doesn't claim necessary protections, unknown components.

↪ Notes: Net graded to Tier E due to it being group regulated.

↪ Notes: Doesn't claim necessary protections, unknown components.

↪ Notes: Supremo Gold made for semi-modularity, necessary protections aren't claimed.

↪ Notes: Supremo Gold made for full-modularity, necessary protections aren't claimed.

↪ Notes: Limited information.

↪ Notes: Doesn't claim necessary protections (IC doesn't support over current either). Somewhat outdated.

↪ Notes: No OCP on 12V, OCP on the minor rails and OPP are both set way too high to be effective, no OTP, poor build quality.

↪ Notes: OCP (12V) is either faulty or not present; faulty OCP on 3.3V allowing for OOS operation, and no OTP per Aris' review. Very loud (50dBA+).

↪ Notes: Not enough extensive testing.

↪ Notes: Predatory/scam consumer practices, including providing rewards for 5-star reviews, and random platform swaps to significantly worse platforms with no difference in model number, branding, or marketing.

↪ Notes: Europe only

↪ Notes: Europe only

↪ Notes: Simplicity HPG, just with a red LED 120mm fan.

↪ Notes: Actual +12V capacity is ~5-10% lower than advertised wattage.

↪ Notes: Platform confirmed through overhead and internal shots provided by the manufacturer.

↪ Notes: SI model, however it appears to be identical to the MP-B.

↪ Notes: Either dual sourced or XWY replaced HKC.

↪ Notes: Either dual sourced or XWY replaced HKC.

↪ Notes: 3 year warranty, inconclusive on platform until further notice.

↪ Notes: 500W seemingly still manufactured according to MC stock.

↪ Notes: Still produced according to MC stock

↪ Notes: Still produced according to MC stock

↪ Notes: Platform was swapped from ATX-0600 to ATX-0200 sometime around 2024. No way to tell the original from the swap. Avoid.

↪ Notes: Platform was swapped from ATX-0600 to ATX-0200 sometime around 2024. No way to tell the original from the swap. Avoid.

↪ 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: 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: Not recommended since no proper testing exists, and numerous issues exist with other Segotep units that were tested.

↪ Notes: Protections are tuned incorrectly to properly pass all ATX 3.0 transient tests.

↪ Notes: Not recommended since no proper testing exists, and numerous issues exist with other Segotep units that were tested.

↪ Notes: EU/JP only? No stated manufacturer warranty outside of mandated EU 2 year warranty.

↪ Notes: Rebrand of the ST-ES 230V

↪ Notes: Actual 12V capacity is 456W. Does not claim OTP. ARGB fan controlled via motherboard header. Hong Hua rifle bearing fan.

↪ Notes: Several issues including very poor ripple suppression at seemingly random intervals, OCP is set way too high on all rails, bad power good signal.

↪ 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: Group regulated.

↪ Notes: Sleeve-bearing fan. OCP untested.

↪ Notes: Failed ATX 3.0 12V power excursion testing, malfunctioning OCP on 3.3V. False efficiency certifications.

↪ Notes: 3 separate versions dependent upon region, most groupreg. Also a 230V only version. Essentially unrecommendable due to platform variation.

↪ Notes: Under crossload, 5V rail experiences high ripple >100mV, doubling ATX spec.

↪ Notes: Poor electrical performance from an unknown OEM; fails all 12V transient response testing per F14 Lab's testing.

↪ Notes: Both the 12V and 3.3V rail fail in ripple measurements, exceeding the ATX specification. No transient response testing.

↪ Notes: Poor electrical performance from an unknown OEM; fails all 12V transient response testing per F14 Lab's testing.

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

↪ Notes: Not independently regulated and no 80+ or Cybenetics certification

↪ Notes: Claims to be DC-DC, but internal shots show otherwise; false advertising.

↪ Notes: Does not claim certain safety protection circuits which is a major deficiency.

↪ Notes: Claimed DC-DC, internal shots from 2023 show otherwise. Confirmed GR.

↪ Notes: Pre production sample used for testing.

↪ Notes: Korean exclusive

↪ Notes: No protections testing, performance testing is not extensive. Need further testing to move beyond tier E since Jiumeng is the OEM.
