The PSU you purchased stated it was rated "Bronze", meaning that it is lower quality than of a "Gold" PSU. When mining, especially 24/7 you will most likely need a "Gold" rated PSU, the cheaper ones tend to overheat, not be able to keep up with the constant demand of power, and puts you at a small risk of a fire.
This may or may not be true.
But Bronze is more about percent of energy wasted. Not whether it will run 24/7/365
The ratings on a PSU are just about efficiency of conversion. The better the rating (bronze, silver, gold, platinum), the more efficient the PSU is in converting the AC power from the wall to DC power to provide to your gear. You can have a gold rated PSU with crap components, just as you can have a bronze rated PSU with stellar ones.
Rosewill PSUs are newegg's house brand and are generally pretty decent.
This is more accurate.
I do wish op did not buy this unit not because it will burn or melt (which it may as I do not know the quality of the pcie wires)
The real problem is this will burn about 50 watts more then a good platinum psu
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151120&cm_re=seasonic_platinum-_-17-151-120-_-Product I have paid under 100 for these from newegg.
Also there are sellers of platinum server psu's on this site.
I fear the op will spend 1 kwatt a day extra on power that is :
3 bucks a month at 10 cent power
6 bucks a month at 20 cent power.
