Your +12V rail is really low on voltage. Push it some more and the PSU will likely die on you. Good PSU brands include Antec, Thermaltake, OCZ, Enermax, Fortron FSP, PC Power & Cooling, Corsair and Seasonic. Antec usually has good-quality PSUs for cheap at Newegg. Their 550W PSU on Newegg is for around $60-70 I believe, and it's a great one.
