Thermaltake toughpower grand rgb 850 tier

Just wondering if this is a good psu for an asus rog strix 1080 and a i7-8700k

Well it's a sirfa built unit, to be honest I have absolutely no experience with sirfa built psu's but I have heard the name. Anyway Tom's gave the 750watt version a good review. Which is what I would recommend, 850watts is beyond overkill for that system, an 850watt psu will not be running in it's efficiency curve with the small amount of load your system will put on it. The 750watt version would be a much better fit. Even 650watts would be more than enough.

It's a high quality power supply. Only real cons are the noise and inrush current.

A large enough inrush current can cause the tripping of circuit breakers and fuses, and may also damage switches, relays and bridge rectifiers. As a result, the lower the inrush current of a PSU right as it is turned on, the better.

If shutting down / booting up the computer is common throughout the day, the high inrush current may be a concern to you.
Your build would consume ~300W at load. This was measured 40.3dBA according the review linked. This is rather loud.

If you haven't bought this PSU yet, there may be better, lower wattage power supplies available to you. For example the Bitfenix Whisper 550.
