Looking to upgrade most of my system in the (hopefully) near future. At present I have a Q-Tec 550W power supply which obviously ain't the best. Having read various threads in this forum I realise that having a decent psu is important. However I don't know if my budget will allow me to go for one of the top line psu's like the ocz. Can anyone recommend a cheaper but still highly reliable brand to look for. ( BTW I am based in the UK if that makes any diff) Thanks in advance for any help you can give me.
