I had a Vantec that lasted me just over 5 years of 24/7 use. Replaced it with a ThermalTake that lasted me a few years before blowing out, but was still covered so they replaced it.
If I had to buy another one now, I'd absolutely consider buying another Vantec, and am somewhat on the fence (but leaning 'yes') on the ThermalTake.

Seasonic

Chieftec psus are great.

I have heard nothing but good things for corsair ones. ATM i am using a thermaltake, lasted me 3 years so far and still is silent. I suggest looking at all the reviews you can find on the web (the tom's hardware one above is a good place to start)

corsair are one of the most reliable but they are also expensive compared to the not reliable brands

Seasonic, Be Quiet, Corsair, CoolerMaster, Enermax, Antec... Here you can retrive how many Watt your pc need. If you haven't a sli or crossfire 550-600W would be more than enough, take a look on this.

Corsair, Seasonic or Enermax.
