I just wanted to chime in regarding DIY PC builds, always buy a high quality powersupply
as it will ensure your computer works reliably for years on end.

2 Brands I have used and trust are

TAGAN
Seasonic X Series

Sure they are more expensive but they are solid and have 5 years guarantees usually.
A boring part of a PC but vital for every components life IMO.
