The Thermalright TR-TGFX 550 is an affordable SFX PSU, meeting the ATX v3.1 requirements for units without a 12+4 pin connector, meaning that instead of 200%, it can deliver 150% of its max power for short periods.
The Thermalright TR-TGFX 550 will be included in my best ATX v3.x & PCIe 5.x PSU picks article once I decide to make a 550W category.
The Thermalright TR-TGFX 550 is an affordable ATX v3.1 compliant unit without a 12+4 pin connector, so it has to follow less strict requirements, which is currently available only in the Chinese market. Thermalright informed me that they might offer it worldwide at some point, which would be ideal, but still, there are not many small form factor PSUs available at reasonable prices in today’s market. The only issue here is that with just 550W of max power, this PSU is mostly for mainstream systems, not those equipped with strong CPUs and potent GPUs.

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.
