Hey, I am thinking of getting a new 400 or 450 watt PSU. I currently have a 300watt psu with its connectors split multiple times. If you think about it, I could just continue splitting the connectors. So how do you know when to stop? What signs would you look for? Also, I notice that some 400 and 450 PSU have dramatically different prices. Anyone know of a really good PSU with ONE exhaust fan. If there is two fans, is one intake and one exhaust? Anyway, I think i'm gonna get the PSU off this site: (at bottom) Canada Computers - PSUs -direct link to PSU section, all in $CDN Any suggestions? I'm thinking of spending around $100CDN.
