Asus wanted MODFETs in its new PSUs for its reasons, but like in the Rog Strix 1200W that I evaluated a while ago, which also uses MODFETs, the one in this PSU is used like a regular FET since Seasonic didn’t use a bridgeless totem-pole APFC converter, which offers minimized energy losses and the highest possible efficiency, but a plain CCM one. Given the standard PFC controller, I believe that using a MODFET in this PSU helps more in marketing than in real-life performance.
The transient filtering stage has all the necessary parts to block incoming and outgoing EMI emissions. Typically, it starts at the AC receptacle and continues on the main PCB.
There is a MOV to protect from voltage surges and two NTC thermistors, with a combined resistance of 10 ohms. Moreover, a bypass relay supports the NTC thermistors.
The two Vishay LVB2560 parallel bridge rectifiers can handle up to 50A together, so they are more than enough to cover this platform’s needs.
The APFC converter uses a single Transphorm TP65H035G4WS GaN and one CREE boost diode. The bulk caps are by Rubycon and offer a combined capacity of 1500uF. They are rated for 3,000 h at 105 °C.
The APFC controller is a Champion CM6502UHHX. It is supported by a Champion CM03X, which reduces vampire power consumption.
This board also holds the unit’s MCU, a Nuvoton M481LE8AE, among several interesting parts. It controls what is shown on the OLED screen and is supported by a Microchip SST26F016B.
The four Infineon IPP60R120P7 primary switching FETs are installed in a full-bridge topology, and an LLC resonant converter is used for higher efficiency.
The PSU’s main transformer.
Eight Infineon BSC007N04LS6 FETs regulate the 12V rail. They are installed on the main PCB next to the main transformers to minimize energy losses.
Two DC-DC converters generate the minor rails.
Nichicon and Rubycon provide the electrolytic filtering capacitors. FPCAP and Chemi-Con make the polymer caps.
You can find more information about capacitor performance and other specs below:
The supervisor controller is a Weltrend WT7527RA. The unit’s MCU might also handle some of the available protection features.
The standby PWM controller is an NCP1342, and the secondary side rectifier is an Infineon BSC014N04LS.
Several polymer and electrolytic caps at the face of the modular panel form an extra ripple-filtering layer.
The soldering quality is terrible. I hope that the normal production units have better soldering quality.
The cooling fan is an Everflow F1214025BL, using a double ball bearing.
Aris i’ve seen that Cougar GLE1000/1200 cybenetics the data OEM said it was CE-Link, but i was bought the GLE 1000 and they said on a label it was Compucase or HEC, which it’s true about this CE-Link or HEC/Compucase ?
As I remember I asked Cougar about the OEM and they told me CE-Link, because at some point it is difficult to recognize who actually made the PSU.
Where is this available in usa or europe
