<div dir="ltr">Chip, <br>It depends on the pixel density. But the general rule is allow for 60mA per LED (20mA per color) at full white. So, for a 5m roll of 32 LEDs/meter that's 160 LEDs or a possible 9.6A draw. It's unlikely it will ever hit this but I <i>always </i>allow for max draw plus 10-20%. <div><br></div><div>MPJA.com sells some very cheap, high amperage supplies: <a href="http://www.mpja.com/5-Volt-Power-Supply/products/534/">http://www.mpja.com/5-Volt-Power-Supply/products/534/</a></div><div>I bought 8 of these (25A @ 5V for $5!): <a href="http://www.mpja.com/5-Volt-Power-Supply-25A-Switching/productinfo/18962%20PS/">http://www.mpja.com/5-Volt-Power-Supply-25A-Switching/productinfo/18962%20PS/</a></div><div><br></div><div>You can also find decent ones on Amazon: <a href="http://www.amazon.com/AC110-Strip-Switching-Supply-Adapter/dp/B0076UJZX0/ref=sr_1_1?ie=UTF8&qid=1422585995&sr=8-1&keywords=5V+10A&pebp=1422585995089&peasin=B0076UJZX0">http://www.amazon.com/AC110-Strip-Switching-Supply-Adapter/dp/B0076UJZX0/ref=sr_1_1?ie=UTF8&qid=1422585995&sr=8-1&keywords=5V+10A&pebp=1422585995089&peasin=B0076UJZX0</a></div><div><br></div><div>Or Jameco: <a href="http://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDrillDownView?langId=-1&storeId=10001&catalogId=10001&position=1&refineType=2&sub_attr_name=Output%20Current%20(A)&refineValue=10%20%3C%3D%20%20%3C%2050&refine=1&history=2yqcd0ad%7CsubCategoryName~Power%2BSupplies%2B%2526%2BWall%2BAdapters%5Ecategory~45%5EcategoryName~category_root%5EprodPage~15%5Epage~SEARCH%252BNAV%40xb01q5sr%7Ccategory~4540%5EcategoryName~cat_45%5Eposition~1%5Erefine~1%5EsubCategoryName~Power%2BSupplies%2B%2526%2BWall%2BAdapters%2B%252F%2BAC-to-DC%2BSwitching%5EprodPage~15%5Epage~SEARCH%252BNAV%40ohlrg75n%7CrefineValue~5%2B%253C%253D%2B%2B%253C%2B10%5ErefineType~2%5Eposition~1%5Esub_attr_name~Primary%2BOutput%2BVoltage%2B%2528VDC%2529%5Erefine~1%5EprodPage~15%5Epage~SEARCH%252BNAV">http://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDrillDownView?langId=-1&storeId=10001&catalogId=10001&position=1&refineType=2&sub_attr_name=Output%20Current%20(A)&refineValue=10%20%3C%3D%20%20%3C%2050&refine=1&history=2yqcd0ad%7CsubCategoryName~Power%2BSupplies%2B%2526%2BWall%2BAdapters%5Ecategory~45%5EcategoryName~category_root%5EprodPage~15%5Epage~SEARCH%252BNAV%40xb01q5sr%7Ccategory~4540%5EcategoryName~cat_45%5Eposition~1%5Erefine~1%5EsubCategoryName~Power%2BSupplies%2B%2526%2BWall%2BAdapters%2B%252F%2BAC-to-DC%2BSwitching%5EprodPage~15%5Epage~SEARCH%252BNAV%40ohlrg75n%7CrefineValue~5%2B%253C%253D%2B%2B%253C%2B10%5ErefineType~2%5Eposition~1%5Esub_attr_name~Primary%2BOutput%2BVoltage%2B%2528VDC%2529%5Erefine~1%5EprodPage~15%5Epage~SEARCH%252BNAV</a></div><div><br></div><div>Wow... long link.</div><div><br></div><div>I generally like to keep around at least a 20A supply for playing around.

Would you mind posting some information on the power supply we should purchase in order to power a 5m strip? When we talked at the last meeting, it seemed you had some links from recommended vendors.
