We all showl know that those values like 500W are not real and the more unfamous is the brand the more far away is the real value from the one thats shown.
Don’t you have one of those 400W Fortrons? This is at a good price and i have heard that Fortrons are immortal.
So we can never know how real are those 500W usually fake brands writ fake values just to make their products cheap. I’ve seen 500W PSUs that can’t handle a 230W system.
So buy a good brand
Fortron has been pretty good in the past, but lately, they’ve been slipping. Antec seems to be pretty universal, so if you can hunt down one of their units in the 600W+ range, you should be fine. The only line you want to steer clear of is their Basiq line. They’re just crappy products that were intended to be entry level, but far too much was cut out to have a solid unit.
