The design looks clean and neat, with several electrolytic caps on the secondary side, which have unobstructed airflow. The heat sinks are not large, especially on the secondary side, where the 12V FETs are on the PCB’s solder side. The soldering quality is good in this unit. The parts that FSP used are of decent quality except for the fan, which is terrible. The FETs regulating the 12V rail are also by a lesser-known manufacturer, but they didn’t create any issues during testing under harsh conditions.
The unit’s design is contemporary, with a half-bridge topology on the primary side and an LLC resonant converter for lossless switching. Four CYStek FETs handle the 12V rail on the secondary side, and a pair of PWM controllers generate the minor rails. Instead of an ANPEC PWM controller on the VRMs, we find one from UPI.
With Fan i can change that terrible in stack? I now its 120mm, but its 3pin or 4pin?
brother i want to ask
right now i have 650 rmx 2018 version of corsair psu
my system was 7900 gre hellhound standart clock
7800x3d standart clock
6400mhz expo ram
3 hdd 2.5 inc
1 ssd 2.5 inch
2 nvme drive
and a lot of fans like 6 fans
is this psu decent ? i am planning to get 5070 in future
this psu was very2 cheap because promotion please answer is it good?
The PSU is more the decent. If your system works ok, no need to change it.
Hello, do you think this psu can handle a 7900xtx?
depends on the CPU also
lets say a 7600x, with a 7900xt
I believe it will be ok.
Hello Aris,
Thanks for the review.
Do you know when the next PSUs from FSP (MEGA, ADVAN) will be available ?
No clue, sorry.
Your in depth reviews of psu’s are amazing.
I hope you review the Lian Li Edge 1300 and new phanteks revolt 1200. I want one of those psu’s for my new built.
only the 750W used Toshin Kogyo caps b?
in the samples I got yes.
