400W be quiet! SFX Power 2, 80 PLUS Bronze, Fully Wired, Dual (2) Rail, 1x120mm Fan, ATX PSU is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from High Quality SFX PSU Great build quality and runs ryzen 5 1500x (stock) and rx470 with no issues. Fan noise isn't louder than other fans in my case but its an 80mm, not 120mm. Cables are just right for mini-itx case, with only one pci-e power connector. Power rating is 400w constant and 450w peak.

Rated 5 out of 5 by from Great product I bought this to replace an old and very noisy PSU. This is really quiet and has solved my noise problem. Also Scan were very helpful, checking the specs of my old PSU and advising me of replacements. Many thanks to Scan.

Rated 5 out of 5 by from Excellent PSU Very well made. Very quiet, as the name suggests. Seems to be the standard size for small cases (I have a Mini-ITX case). I like the sleeved cables - easy to route.
