I just build a new DAW and I used a 750 Watt Coolmaster PS, I had weird issues from day one with Blues screens on boot up. After only one month the PS died. 30 minutes before a client was coming over!!!
I had a 165 Watt no name brand PS sitting there and I quickly swapped it over.
I ran the whole session for 4 hours hoping it would not also die. It didn't.
I used it for a week and not only did it work,,, my random blue screens are now gone.
I replaced the 165 watt with a Sparkle 450 Watt from a local tech. They said that's the only brand they have used in the last 15 years without issue.
They also said 750W was way overkill for my system. That's why the 165 watt had no problem. She said modern hardware is way more energy efficient and the days of huge power supplies are in the past unless your a gamer. She said a 350W would be a good match up and so to pacify my old school thinking sold me the 450W.
Anyhow, my home built machine is running top notch now so while Power supplies are important, it's the
quality, not the quantity that counts.
