KRPW-FL600W/92+

Is there any japanese forumer who can talk about that PSU and its availability?

It's not the only 600W fanless. There is the very niche SilentMaxx 600W watercooled PSU:

Thanks for pointing it out.
Unfortunately that one looks like a fake 600W unit: apparently on its label it's stated that it cannot exceed 506W of combined power.

Plus SilentMaxx so far doesn't have a stellar record of fanless PSUs: their 400W model had a plethora of problems (buzzing and overheating mainly).

BTW, the 400W Seasonic model can run up to 600W also, according to torture tests. It has a hard off at that point, but it can do it. See my sig for a high-end system with it. I'm probably stressing it to about ~500W. (It has 2 HDDs, 4 SSDs and an HDMI capture card)

OT: actually drawing about 500W from your 400FL is possible under some circumstances (either with heavy OC and heavy voltages for both CPU/GPU, or when benchmarking/stress-test with Linpack/Prime/Furmark), but not that much probable in a relatively quiet system (if your one were so).

But broadly speaking, overload capabilities shouldn't apply: the platform used for the above mentioned "japanese" PSU can be usually overloaded by about 25-30%, but I wouldn't consider it as an about 750-800W PSU.

A typical HDD draws about 10W; a typical SSD draws about 3W; capture card maybe 20W.
The power in your system is being sucked up by the i7 CPU, the graphics card, and their VRM's. Easily over 200W at full load.
