For two 12V rails, that's a total of 34 amps -- about the same as a Turbo-Cool 510 dee-lucks.
I thought for sure Fortron had a consortium with Apex Technologies, and that they had a hand in building the ALLIED PSU's. I have an ALLIED 500W job that only sports about 20 to 24 amps on the 12V rail, but it's fine.
Your rail voltages should fall within +/- 2% of their 12, 5, and 3.3 volt requirements, so look for reviews that evaluate that.
Also, you would ideally like to find a web-site that has a comprehensive database comparing 50 to 100 PSU's, and if it doesn't include this model of the Fortron, look for a similar model. There is an "efficiency" rating specified as a percentage, which purports to show how much AC power is converted to electricity as opposed to heat. Another consideration.
From my experience with the ALLIED, I'd say this is a pretty good risk for an $80 or $90 PSU, but look for more info as I suggest above. 100,000 hrs MTBF is nothing to sneeze at. See if you can't find Fortron's web site and get an idea of what warranty they offer. If it is greater than 1 year, it is a good indicator of their confidence in the unit's quality. Every returned or RMA'd PSU costs them money under warranty, so the warranty period is a sincere indicator of the unit's longevity and reliability.
