This is CWT’s CSE platform, using top-notch parts, including Infineon and Vishay FETs and Japanese caps for increased reliability. The cooling fan, manufactured by Hong Hua, is also of high quality and has a fluid dynamic bearing to keep noise output low. On the primary side, besides the APFC converter, which has been used in every desktop PSU for many years now, we also find a half-bridge topology and an LLC resonant converter for lower switching losses. On the secondary side, a synchronous rectification scheme handles the 12V rail, with eight FETs total, and the minor rails are generated through a pair of DC-DC converters.
The bulk caps and several caps on the secondary side are by Chemi-Con, and we also find several Rubycon and Nichicon electrolytic caps. On the secondary side, many polymer caps are also used for ripple filtering.
Hi crmaris, is this one better then the first core reactor? Price difference is big.
If you don’t care for ATX v3.0 and the 12VHPWR cable, you can go to the first version.
Hi crmaris.
After buying this power supply, I decided to test it with a tester from Aliexpress. When the tester is turned on, it starts beeping and Power Good flashes with a reading of 130.
All other indicators are normal.
Can you tell me if this is a factory defect or can I use this power supply?
P.S. I checked the tester on my old Deepcool PQ750M power supply. There it works without beeping and PG blinking.
You can use the PSU. These cheap testers are for basic stuff only.
Thank you, for your reply.
