or find an oem list and make sure to avoid Corsair/CWT (every powersupply I've had issues with has been Corsair units built by CWT).
CWT isn't junk but I avoid PSUs using them personally - the vast majority of times over many years where I've had issues with PSUs to deal with it has been CWT based units, or back in the day Q-Tec... probably some stuff I've forgotten but CWT has been notable enough in terms of problems.
