Okay guys I just got one of these 520W units after all the glowing reviews on this forum and others. Unfortunately, I can't seem to find what all the fuss is about. The fan is loud on ASM when it has to turn on. Bear in mind my PC is, by all accounts, pretty damn quiet. I've got a Zalman 7700-Cu with Nexus 120mm fan attached running at <5V. Also a single other fan (now a dustproof Silentmaxx 80mm) keeping my 7800GT cool. 2 Spinpoints suspended in a p180 case. My existing PSU was a Seasonic S12. Now the PSU is the lowdest component in my PC, the harddrives coming a close second. The Nesteq is silent but even with PC at idle when it spins up the noise is very noticible. when gaming the fan speeds up quite often. I'm presuming all the glowing reviews have come from ppl who rarely stress their units or maybe I got a dud? Just wondering about your opinions. And perhaps an alternative?
