Another good one

Well-made, efficient, runs cool and quiet (quieter than the case fans, anyway)

Sleeveless cables, and virtually no online documentation -- minor annoyances

This is a new 80-Plus Bronze version of the SS-400ET 80-Plus (no Bronze) model from five or more years ago. Apart from the small efficiency increase, the stats are the same. Its eight cables, measured from the back of the PSU to the back of each connector, are:

ATX12V 24-pin (mobo): 22" (55.9 cm)
EPS12V 8-pin (CPU): 21.7" (55 cm)
ATX12V 4-pin (CPU): 21.7" (55 cm)
SATA power: 19" and 25" (48.2 cm and 63.4 cm)
SATA power: 19" and 25" (48.2 cm and 63.4 cm)
Molex 4-pin: 12.75", 18", and 23" (32.4 cm, 45.6 cm, and 58.4 cm)
Molex 4-pin/floppy: 19" and 24" (48.2 cm and 61 cm) -- the end one is the floppy drive connector
PCIe graphics 6-pin: 22.8" (58 cm)

I'm using it to run an ASRock Z87M PRO4 microATX motherboard, 65W Core i5 CPU, Radeon HD 7850 graphics card, 8GB of DDR3 SDRAM, 7200 rpm HDD, SSD, and CD/DVD burner, plus the case's three fans. No problems. Whatever their shortcomings in the documentation department, SeaSonic continues to make quality mid- to low-watt PSUs.

Some problems

Price

Fan degradation

I have purchase about 15 these PSUs from various vendors and 2 have had fan degradation that has increased the audible presence to the point of being unusable in a office environment. This degradation occurred within 6 months of purchase.
