Best 650ishW for around £100

[sqwerty]

I was looking for the same, a decent 650w. Ended up getting the Xigmatek Centauro 700W for about £85. http://www.jonnyguru.com/modules.php...Story&reid=294

I was running a sapphire 7870 with a gx500w for over a year and never had any problems. That was with multiple HDDs, an fx6100 and 16gb of oc'd ram.
