Thermalright TR-TGFX 550 ATX v3.1 PSU Review

Efficiency Normal, Light & Super-Light Loads

Efficiency is high at normal loads. Do not let the last place in the charts above fool you. I didn’t have a similar-spec and price SFX unit to use for comparison, so I used the ones I had that belong to higher categories. Efficiency is also high at light loads; at 2% load, it doesn’t reach 70%. Nonetheless, it meets the 60% requirements.

Average Efficiency

The platform’s average efficiency is high enough for a Platinum level at 115V, while at 230V, the unit is classified as Gold in the Cybenetics scheme. It loses the Cybenetics Platinum rating at 230V because of the low PF and the increased standby power.

Average PF

The APFC converter needs tuning for higher performance, especially at 230V.

Average Efficiency 5VSB

The 5VSB rail is not that efficient. I didn’t expect more, though, from a budget-oriented platform.

Vampire Power

Vampire power is high.

  1. Can you do a review of the Thermalright TP-1000/1200? There’s a frustratingly low amount of information about it. Thanks in advance.
