I usually base myself on a lot of things when buying a PS and price is not one of them,
this Ps has a good spec sheet, over load and over voltage protections, that means if you ever short one of your wires you get to keep your rig's devices intact and that's a big +, it has good 12V rails ,+12V@16/28A, has been run for 100K hours at 25ºC and a decent efficiciency Min 65%,Typical 70% (at full load)
+some peeps took the time to praise it, (maybe fake)
I would trust it as much as a brand name with the same specs (maybe more on some)
