So, in other words a lot of these companies have good PSUs????
Keep away from off brand and you'll find that the differences between good units aren't that great. Some companies offer a better build quality in general (better quality of assembly, soldering etc), or a higher grade of componentry ( capacitors, rectifier etc), but in general a lot of the actual end product (12V, 5V, 3.3V, ripple characteristics...) are within a few percentage points of each other.
A lot of vendor choices generally boils down to cabling options (fixed, partial modular, full modular), cable length and plug spacing, and largely subjective issues such as whether the cables are fully sheathed, or the colour of the unit.
I'd suggest a quick browse of reviews (
TPU has an extensive review database) once you short list some suitable candidates. Don't get too caught up in the minutiae of the reviews or you'll be reading forever and a day.
As for FSP, their AURUM units have very good specifications and reviews. Because of their backround in no-nonsense server PSU's their consumer units can look a little plain. This does not reflect their ability.
They can also be reasonably priced in comparison to other units with the same feature sets.
