600 W power supply with a very good price. Turn with me now and then for a few months, no problem in terms of heat dissipation, noise and operation (fueling an i5, a GTX 550, a few GB of RAM and a few hard disks). Not necessarily suitable for a PC Gamer or low energy vocation machine (rather move towards 80+) but in his view, this PSU is ideal for a secondary PC with an entry-level / mid-range configuration .
