all the forums say that EVGA is great quality
Are these the same forums that said an RX570 needs 750+ watts, which is double what the manufacturer says?
You cannot judge a PSU by its brand name alone. EVGA has models with "Great Quality" such as their G2 series. However, this does not carry over to their entire lineup. There is a reason why a 600w EVGA W1 cost $40 less than a model I would consider good like an
EVGA GQ 650w. They clearly had to cut quality and design somewhere in order to achieve this difference in cost.
Honestly, the EVGA W1 600w its similar to the TT SMART 700w in the way that it is group regulated (like the majority of PSUs from 15 years ago), lacks DC-DC converters, and certainly no LLC resonant tech. Add that onto the fact that these units use lower quality components inside, and they just aren't good at all. I would never call this model "Great", unlike other EVGA models.
You can get by with it most likely without a disaster, but for how long?
