Edit for UPDATE-
Ended up buying Corsair HX1000 (1000W)
I am trying to build a work related PC and like everyone struggling to get hold of parts! Some 1000W+ PSUs just came in a shop nothing else available, so I am debating if Be Quiet is a good brand? Normally I have bought Corsair PSUs. Also, what wattage should I get?
A- be quiet! Dark Power Pro 12, 1500W, $400 (Within a month), 7 year warranty
B- be quiet! Straight Power 11, 1200W, $222 (This available now), 5 year warranty
Be quiet recommendation-
