Load regulation is tight. The PSU’s low capacity helps in that.

Ripple suppression is mediocre, especially at 12V. This is a great shame! With more and higher quality caps on the secondary side, this wouldn’t be an issue, but Thermalright targeted budget-oriented users and an increased number of higher-quality caps would increase the production cost.

Great review, definitely worried about its inrush current, which seemed really high. I also found TR-TPFX-650 (Platinum), would you be able to do a review on it? I mean it claims to use better material, but barely any review out there.

Thanks
Only if TR sends me a sample. I cannot find them here in Cyprus.
Can you do a review of the Thermalright TP-1000/1200? There’s a frustratingly low amount of information about it. Thanks in advance.
If I manage to find them sure.
