Despite the small PCB, there is enough space on the secondary side to allow for good airflow. When there is enough distance between parts, airflow is better, and the heat can be transferred easily from the PSU’s internals. The installation of both VRMs, generating the minor rails, on a daughter board helped in this. The primary side’s heatsink is large enough to host all parts that require strong cooling to cope with high loads. The pair of bulk caps is necessary to provide a long hold-up time because there is no space for a single, huge one.
The soldering quality is good, and on the solder side of the PCB, we find the eight FETs regulating the 12V rail. The 120mm cooling fan is the same one used in the SF1000L, and it uses a fluid dynamic bearing and is pretty strong, with 0.55A max current input.
I really hate wiring on this PSU. It’s very hard to fit bend and to fit inside mini-ITX case.
In my country it’s on promo, at the same price as Cooler Master V850 Gold V2. Which one should I get?
It depends on whether you need an ATX or an SFX-L PSU.
if I’m getting extension cables for the Corsair SF850L do I need special cables or will this work ok

thank you!
Extension cables are always compatible so that it will work.
Is the included 12VHPWR cable sufficient/safe for powering an RTX 4090 FE or should a 3×8 cable/adapter still be used? If it is sufficient and totally safe, does the manual specify which ports to use or doesn’t that matter?
Yes it is ok, and it is set at 600W. You can hook it in any port that fits.
