mark84 30 Posted December 14, 2012 A Better Way to Compare PSU Efficiency. By using power lost vs load. Share this post Link to post Share on other sites
mark84 30 Posted December 17, 2012 Is it worth investing in a high-efficiency power supply? An interesting read. Seems like paying the extra for higher efficiency, monetarily doesn't benefit you a whole lot. Unless you run it constantly loaded, then you can see ROI after a couple years. (This is all with USA power pricings though. In Aus, it might pay off sooner) Share this post Link to post Share on other sites

(This is all with USA power pricings though. In Aus, it might pay off sooner) fairly bad review unfortunately they use a cheap power meter which can be way off on some psu and close to accurate on others but there accuracy varies depending on the load aswell they are going by the psu 80+ ratting which is a very rough guideline as some psu dont even reach there efficiency rating and then there are psu out there like the fsp raider bronze $60 which can get over 90% efficiency which is well above bronze requirements so they really need to test the psu efficiency curve if they are going to compare them like this yes au power costs twice as much as us power and is rapidly increasing edit say we compare these psu Thermaltake Smart SP-430P 80Plus $50 Load Efficiency PFC 5% 63.31% 0.790 10% 74.09% 0.835 20% 80.87% 0.896 50% 83.64% 0.937 80% 83.19% 0.967 100% 82.84% 0.973 110% 82.23% 0.975 FSP Raider 450W 80Plus Bronze $60 Load Efficiency PFC 5% 79.49% 0.827 10% 85.36% 0.881 20% 89.07% 0.928 50% 90.54% 0.941 80% 88.93% 0.967 100% 88.21% 0.979 110% 87.57% 0.984 asuming 24\7 use at 30c per kw will exagerate these numbers but it makes for a good baseline 88w ~20% waist power = tt 16.83w $44 fsp 9.61 $25 = $19 saved per year 220w ~50% = tt 35.99w $95 fsp 20.81w $54 = $41 saved per year COOLER MASTER Extreme 2 475w unrated by 80plus 77.2% efficent at ~50% load 220w waist power = 50.16w per hour $131.8 a year so you can save $77 per year by getting a more efficient budget psu Corsair TX-850 V2 bronze $169 80% load 83.7% efficient $350 per year Enermax Platimax 850W $275 80% load 89.4% efficent $210 per year CoolerMaster 600W Extreme $69 521.4W dc =727w ac Antec EA-650-Platinum $119 524.8w dc =581.8w ac $384 per year difference between these two psu assuming the cm lived that long without killing your pc Edited December 17, 2012 by Dasa Share this post Link to post Share on other sites
