Not quite as cheap as previous deal from PCCG, but looks competitive if you can click and collect.
Speculative A - tier in the cultists PSU tier list https://cultists.network/140/psu-tier-list/
Fully modular design, 10 year warranty, Japanese capacitors. I think it's a good option compared to something like the corsair rm850x if you want the new 12VHPWR connector, although not battle tested in the same way.
I'm not sure if expiry date is reliable, page says "Hotdeal Ends in 2 Days or While Stock Lasts!"
I've got this. Its fine and super quiet. Other than that how to judge a psu ? It has the new type of connector. Its big bro 1000w is rates top quality here https://cultists.network/140/psu-tier-list/ I assume this is similar
