Need help with choosing a psu Tags: Power Supplies Components Last response: December 27, 2012 11:53 PM in Components Share refmon December 27, 2012 10:57:05 PM Hey im going to buy this build http://www.tigerdirect.ca/applications/SearchTools/item... with some parts like the case and memory changed. here are two notable things I noticed about the psu, http://www.tigerdirect.com/applications/SearchTools/ite... 1. It has no Active PFC protection. 2. It's not 80Plus certified (in fact, it has only 72% efficiency according to Kingwin) So im not sure if I should still buy it for if someone has an idea for a replacement, post it More about : choosing psu rolli59 a c 499 ) Power supply December 27, 2012 11:36:15 PM Yes that PSU is crap and your rig will run on a 450watt quality PSU. Here is a quality XFX 550watt http://www.ncix.ca/products/?sku=59615&vpn=P1550SXXB9&m... groundrat December 27, 2012 11:53:39 PM I know they are more expensive, but I prefer 80+ rated PSs. The one that Rolli59 rec'd is good and less expensive. Stick with Antec, Corsair, Silverstream, Seasonic, XFX or higher end Rosewill. Although I have friends that love Kingwin, I have never had much faith in them. Can't find your answer ? Ask !
