An operating temperature range that does not say full power is not enough. A maker table with load steps gives the full-load row, such as 40 °C at full load next to 50 °C at 80 percent load.

Cables and connectors

4 of 7 differ

CablesiOne row per kind of cable that runs from the PSU to a device. Connector is the plug at the device end. Count is the number of those plugs over all cables in the row. Length runs from the PSU end to the first plug. Adapters that plug into other cables are left out. Use 16-pin PCIe when the maker names a 16-pin GPU cable without saying 12V-2x6 or 12VHPWR. A cable from a 12V-2x6 socket on the PSU to 8-pin plugs is a cable, not an adapter, and counts as PCIe 8-pin. When the maker's documents name one GPU cable both 12VHPWR and 12V-2x6, use 16-pin PCIe and name both in the source note. Cables of one connector kind with different lengths or wire gauges get one row each.

Fan bearingiUse the maker's bearing name. FDB and S-FDB are fluid dynamic. HDB is hydrodynamic. Noctua SSO and SSO2 are SSO. Corsair Magnetic Dome is magnetic dome. A brand bearing name that fits no option is Other.

Fluid dynamic (FDB)1Maker product pagesuper-flower.com.tw/products-detail/LVIII-P-PRORead 15 October 2026Overview: 120mm Fluid Dynamic Bearing Fan. Spec table: Ultra Silent F.D.B. FAN. The Cybenetics sample had a double ball bearing fan, which the report names ZFB122512H.

Fan modeiSemi-passive means the fan stops at low load, often sold as zero RPM, hybrid or 0 dB mode. Fanless means the unit has no fan.

Semi-passive3Retailer pageamazon.com/dp/B0FXNSVSLDRead 14 October 2026From the manufacturer: Zero fan mode ON, available to stop the fan's operation when TDP is below 55%. Whether a switch turns it off is not stated, so fan_mode_switch is empty. The datasheet rated fan speed starts at 500 RPM.

Semi-passive1Maker product pagesuper-flower.com.tw/products-detail/LVIII-P-PRORead 15 October 2026Overview: Zero RPM with fan ECO Mode.2Measurementcybenetics.com/evaluations/psus/2912Read 15 October 2026DUT Information: Semi-Passive Operation ticked (selectable). The typical load table shows the fan at 0 rpm from 10% to 40% load at 115V.

Fan mode switchiA button, switch or software setting lets the user turn the semi-passive mode off so the fan always spins. A unit without a semi-passive mode, whose fan the maker says always spins, has no switch, so it is false.

Protection and parts

1 of 3 differ

ProtectionsiProtections the maker lists, or a retailer spec table copies from the maker, plus protections the Cybenetics protection tests show working (UVP, NLO, SIP). The Cybenetics manufacturer list has no OVP or UVP row, so do not build the list from it alone. A protection that is not listed may still exist. No-load covers no-load operation and no-load protection. Fan failure is a maker's fan failure protection or fan safeguard, also when the Cybenetics manufacturer block lists it.

Over-current (OCP), Over-voltage (OVP), Under-voltage (UVP), Over-power (OPP), Over-temperature (OTP), Short-circuit (SCP), No-load (NLO), Surge and inrush (SIP)1Maker spec sheet (PDF)storage-asset.msi.com/datasheet/power-supply/us/MPG-A1250GS-PCIE5-II.pdfRead 14 October 2026Protection line: OCP / OTP / OPP / SCP / OVP / UVP / SIP / NLO.

LVP is the low voltage protection and is stored as UVP. NLO comes from the Cybenetics protection tests.2Measurementcybenetics.com/evaluations/psus/2912Read 15 October 2026Protection Features: OPP at 117.51%, +12V OCP, OTP, SCP to earth, UVP at full load 90V and no damage at 80V, NLO ticked and SIP shown (surge MOV, inrush NTC and bypass relay). Fan failure protection is not present.

All-Japanese capacitorsiThe maker states that every electrolytic capacitor is from a Japanese maker. A Japanese bulk capacitor alone is not enough. A spec row such as "Japanese capacitors" that names no exception counts.

Yes3Retailer pageamazon.com/dp/B0FXNSVSLDRead 14 October 2026From the manufacturer: This power supply uses 100% Japanese 105 C capacitors. The MSI datasheet says 100% all Server-grade 105 C capacitor and names no origin.

Yes1Maker product pagesuper-flower.com.tw/products-detail/LVIII-P-PRORead 15 October 2026Overview: 100% Japanese 105C Capacitors. The Cybenetics parts list of the 1000W sample also shows 5 CapXon electrolytic capacitors, which the claim does not cover.

MTBF (claimed)iThe maker's mean time between failures, such as 100000. An MTTF figure for the whole unit counts too. An MTTF for the fan alone does not. The test temperature goes in the source note.

WeightiWeight of the unit alone. Use the Hardware Busters figure on hwbusters.com when the maker states none, not a copy on another site. Maker weights that include cables or the box, such as Corsair's, and retailer packed weights are not stored. A net weight counts unless the maker says it includes the cables.
