Enermax, Antec, FSP, and Akasa are all stonking PSU's, you'll notice I've missed a few the Tagens are OK when they work properly then you have hell on getting them RMA'd so avoid them I've had 3 VERY bad issues with them.
I forgot the Hiper's are also very good as are the OCZ's although OcUK have stopped selling them for some reason, my mate has a Hiper and I was blown away with the quality for the money Enermax are well good PSU's but rather bland compared but I've never had an issue with them I personally love my OCZ 600 it's noisier than some others but the rails don't move 0.01v from idle to full load measured with a digital multimeter and that is the best I've ever seen, incidently the Hiper does drop the 12v a bit but well within the ATX spec but the Tagen's go WAY out of spec when they go wrong I had a 580 that dropped the 12v down to 10.8v under load wouldn't buy another with someone elses money.
Sorry for rambling but I would hate you to have some of the rubbish I've copped for.
