SFX Power Supplies

↪ 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: The OCP trggering point for the 5VSB line allows for extremely excessive ripple.

↪ Notes: The OCP trggering point for the 5VSB line allows for extremely excessive ripple. 12V line voltage ripple spikes around the 80-90% load range.

↪ Notes: The OCP trggering point for the 5VSB line allows for extremely excessive ripple.

↪ Notes: PPFC; e-waste

↪ Notes: The 5VSB OCP triggering point allows for excessive ripple. Ripple exceeds requirements for tier A under crossload, 100% load, and 110% overload.

↪ Notes: Platform is somewhat mediocre, no direct transient response testing available and not the best choice of capacitors.

↪ Notes: Basically G1278 updated to ATX 3.0

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

↪ Notes: 230V input only

↪ 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: Class-leading performance, excellent build quality, relatively quiet for the capacity.

↪ Notes: Decent electrical performance let down by poor transient response, a sleeve bearing fan, and other miscellaneous problems.

↪ Notes: Decent overall performance despite being ACRF on the primary side, double ball bearing fan.

↪ Notes: Decent overall performance despite being ACRF on the primary side, FDB fan instead of DBB as in the lower wattage GM models.

↪ Notes: Out of ATX spec ripple on 3.3V rail, fails 80+ Gold efficiency spec,

↪ Notes: Malfunctioning OCP and OPP on +12V line (voltage out of spec), poor transient response on minor rails, failed to meet 80+ Gold rating.

↪ Notes: Doesn't see the same problem as the 850W variant because of its lower capacity.

↪ Notes: Fatal design flaw that causes an X cap to melt under 100VAC; potential fire hazard. Two samples also died during LTT Labs testing.

↪ Notes: Two samples no longer operated after protections testing per LTT Labs, which is not ideal, but all protections did function.

↪ Notes: White 750W available.

↪ Notes: Modular board protudes from the unit

↪ Notes: Low quality sleeve bearing fan, ripple exceeds ATX specification, low quality capacitors, and a 3 year warranty.

↪ Notes: Malfunctioning OTP per Aris' testing

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

↪ Notes: The OCP (+12V and 5VSB lines) and OPP triggering points are set way higher than necessary. Mediocre transient response. 7 year warranty.

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

↪ Notes: Excellent overall performance, component, and build quality, quietest SFX unit in its class.

↪ Notes: SX-G upgraded to Platinum efficiency.

↪ Notes: Two samples (same platform) no longer operated after protections testing per LTT Labs, which is not ideal, but all protections did function.

↪ Notes: Not suitable for use with high ambient temperatures over 40C/~100F, as the fan cannot keep up with the cooling demand.

↪ Notes: Protechnic Electric sleeve bearing fan.

↪ Notes: OTP either set over 200C or not present; extremely loud (over 42dbA) under full load, and mediocre performance all around.

↪ Notes: 550W tested, 550/650W TGFX ATX 3.0 compliant but no 12VHPWR/12V-2x6. Mediocre ripple & poor inrush current. Cybenetics Platinum/Gold.

↪ Notes: Single-sided PCB, voltage drops right before protection trip points on the minor rails; however, the protections did engage in time.

↪ Notes: Multiple inexcusable protections malfunctions despite good electrical performance.

↪ Notes: Over 500mV of ripple at 110% load on the +12V line is inexcusable (over 4x the ATX specification limit). Clearly a major design flaw.

↪ Notes: Malfunctioning protections that don't engage in time before the minor rails experience a huge voltage drop out of spec.

↪ Notes: The OCP and OPP triggering points are set much higher than necessary.
