https://www.techpowerup.com/309618/major-psu-oem-channel-well-technology-showcases-new-atx-3-0-reference-psus-at-computex-2023 Channel Well Technology, or CWT in short, is a major OEM of PC power supplies and notebook power bricks. Several major PSU brands source their PSUs from CWT, across all market segments. The company apparently also sells certain reference PSUs of its own in the retail channel, the way Seasonic and Fortron (FSP) do, and showcased its latest ATX 3.0 + PCIe Gen 5 compliant PSU models. The CTT series of enthusiast-segment reference PSUs comes in 1650 W and 1350 W variants, and boast of 80 Plus Titanium efficiency, and two 16-pin 12VHPWR connectors, each capable of 600 W continuous output.
The CTB Series are the company's top SFX-L PSU models, and meet SFX12V 4.0 (ATX 3.0 analogue) standards, along with PCIe Gen 5. These come in a 1000 W variant with 80 Plus Gold efficiency, and a 1200 W variant with 80 Plus Platinum, both feature a 16-pin 12VHPWR connector. These use 120 mm fans. The CSX Series PSUs target the traditional SFX form-factor, and come in two high-wattage models—1000 W with 80 Plus Platinum efficiency, and 850 W with 80 Plus Gold. Both models offer a 600 W-rated 16-pin 12VHPWR connector.
The HPF series upper mid-range ATX PSUs come with semi-modular cabling (the 24-pin and two 4+4 pin EPS connectors are fixed). This series meets ATX 3.0 and PCIe Gen 5 specs, and comes in 1000 W and 1200 W variants, with 80 Plus Gold switching efficiency. Both offer a 16-pin 12VHPWR connector. The GPW series forms the thick of the company's mid-range, and comes in 750 W, 650 W, and 550 W variants, with 80 Plus Gold Efficiency. At least the 750 W variant offers a 16-pin 12VHPWR, we're not sure about the lower-wattage models.
The HPC series target the high cost-performance gaming PC market, and despite their rather high wattage, would be slotted in the company's mid-range. These come in 850 W and 1000 W capacities, with 80 Plus Bronze switching efficiency, and offer full modular cabling, along with one 16-pin 12VHPWR connector, along with an ARGB LED-illuminated fan. The GPX series are slightly premium mid-range PSUs with full-modular cabling, but 550 W, 650 W, 750 W, and 850 W variants, with 80 Plus Gold efficiency, and 12VHPWR connectors on at least the 750 W and 850 W models. The CSZ is a premium-segment lineup, though not quite enthusiast. These come in 850 W, 1000 W, and 1200 W models, with 80 Plus Gold and 80 Plus Platinum efficiency ratings, and at least one 16-pin 12VHPWR connector on all models.
The higher wattage PSUs with two 16 pin 12VHPWR connectors is interesting.
