This looks OK 👌 but according to Gamers Nexus it's the Gigabyte 750 and 850's that will really give you a Hot 🔥 Time. 😃

I've been using this one for a year now, first with 9900k+2080super then 3090, no complain...

(Actually, only complain is the "click" sound when turning off, it's a little annoying to me, but I guess it's normal)

I have one of these, and no complaints. I stepped up from a 750 unit that seemed to be struggling to keep up with my 3080 (though it may have just been that I was running both power connectors off the same split cable), but all's working well now.

This is a good deal, before prices started coming back to normal, I got the 750 for about the same price a year ago. Has had no problems with my 3070 Intel build.

top tier PSU. They also have great warranty support, but you likely won't need it. These are great.

This is a great deal, I got this exact PSU for $180 a year ago, obviously it was a price hike. But was worth it imo

Great PSU. Currently use this with a 3080 Ti and a i7 10700k Overclocked. It also has a 10 year warranty.

This or the seasonic on FP now. Given that this is 100 more watts.. One day if GPU prices normalize, I would like to upgrade so will need better PSU..

Thanks. Now the question is.. Should I hoard PSU or wait till I really need it.. just got a 3060ti so won't be upgrading for a while given the crazy GPU prices.
