WeeboTech Posted March 24, 2008 Share Posted March 24, 2008 Thought I would post some links to power supply calculators. If anyone has others, feel free to add. http://www.extreme.outervision.com/psucalculator.jsp http://educations.newegg.com/tool/psucalc/index.html Quote Link to comment
JRS Posted March 25, 2008 Share Posted March 25, 2008 http://www.corsair.com/psufinder/default.aspx Corsair's is definitely more "marketing" driven as it does not calculate wattage but returns the corsair psu's that should fit your entered requirements. Quote Link to comment
RobJ Posted March 25, 2008 Share Posted March 25, 2008 Here's an old one, too out-of-date to be very useful, but does still have some 'educational' value. You have to manually calculate an adjusted wattage for more than 4 drives. http://www.journeysystems.com/?powercalc There is some value in trying all of these, to get a better feel for what you really need, rather than trusting any one vendor's advice. I must say I liked the Corsair choices, and the Newegg value seemed very good, conservative. The eXtreme Outervision one seemed low, but more detailed. Quote Link to comment
WeeboTech Posted March 25, 2008 Author Share Posted March 25, 2008 The eXtreme Outervision one seemed low, but more detailed. I've found that with peripherals, we tend to oversize power supplies. My opinion was that the Outervision was pretty accurate, but did not cushion the environment for large amount of growth. In each of my manual estimated calculations, The outervision was close to what I calculated, albeit, more accurate. Quote Link to comment
sirwired Posted March 28, 2008 Share Posted March 28, 2008 The problem with some of these online calculators is that they are meant for typical PC's, or maybe gaming PC's. Our servers require pretty much nothing but gobs and gobs of 12V current that isn't limited to just supplying the mobo/CPU. That makes PSU selection a little trickier than an online calculator that just adds up the watts. The CPU's required to run most unRAID servers is barely even a rounding error compared with the 12V necessary to power the drives. It looked like the "Pro" version of Outervision one would work, but the NewEgg one is useless for our purposes, since all it spits back is a wattage number. SirWired Quote Link to comment
