I'm designing my first system, and would like some help on how large of a UPS is needed, I'm doing a Supermicro x11 system with the capacity to power as many as 14 hard drives. Based off the power calculations it will have an 850w PSU (total peak = 582 + 25% = 738).
All I want from the UPS is to shutdown the system safely. I will manually restart it. I would like to get the smallest UPS as possible, but with a high margin of safety. Based on the APC's UPS Selector widget, a 1000VA/600W unit will give 5 min of runtime for a 500W load. My gut tells me that this would be more than sufficient, but I really have no idea if its on the edge, or need to go bigger and accept the higher maintenance costs (e.g. batteries for the APC BR1000G (600W) and BR1500G (865W) are roughly $40 and $70 respectively).
I apologize for this really really stupid post (I'm quibbling over $30 every year or two). But I've only owned one UPS in my life. It was an APC purchased 2 decades ago. It was buggy, loud, and the battery was around $250 a pop (lasted a year if lucky). Over the years apparently I've developed UPS hatred. I don't care if its only a $30 difference. I'd like to get the smallest UPS possible. Any input would be greatly appreciated - Thanks!
