T Efficiency Power Supplies

↪ Notes: Totem pole PFC

↪ Notes: Updated N series

↪ Notes: Optional "5V Boost" button which increases +5V by 200mV; bridgeless PFC. 12V-2x6 connector has thermistors to act as an "OTP".

↪ Notes: Bridgeless PFC, OCP needs tuning on all rails

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

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

↪ Notes: Grey label; potential issues with heavy transient loads.

↪ Notes: Grey label; totem pole PFC, fully digital aside from 5VSB.

↪ Notes: Overall performance is not that great despite a capable platform. Platform just needs to be tuned better.

↪ Notes: Overall performance is not that great despite a capable platform. Platform just needs to be tuned better.

↪ Notes: Identical to the ASRock Taichi, however until further testing exists, it will not receive a "+" grade. See teardown here.

↪ Notes: Insane performer, extremely quiet, however the 850W model is discontinued.

↪ Notes: Interleaved bridgeless PFC, semi-digital.

↪ Notes: Digital primary & 12V; analog minor rails & standby.

↪ Notes: Very high ripple on the 12V rail for a unit of this caliber.

↪ Notes: SAMA increased the power-good signal's hold-up time by a lot, which makes this PSU a possible danger to hardware.

↪ Notes: White versions of Focus (yes) Gold / Platinum and Prime Titanium.

↪ Notes: Fanless

↪ 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: 5VSB OCP needs tuning (59mV ripple); An EPS cable can fit into a PCIe socket and vice versa, but they're not electrically compatible.

↪ Notes: Semi-digital

↪ Notes: Malfunctioning safety protections
