Only telling you the requirements as listed on Newegg. Keep in mind that all PSUs are not created equally and they do "wear out" and eventually die. Yours may not have been up to the task while the other one was. Running a PSU "maxed out" or beyond its limitations is a sure way to speed up the death of the PSU. Sorry for your hassles.
BTW, here is the link for the HIS HD5670 (I assume this is the one you had). Note the Power Requirements:http://www.hisdigital.com/us/product2-505.shtml
