I cannot stress this enough, I tell anyone I speak to about computers that the most crucial component in the system is your psu. Always replace a horrible psu. A bad psu is like driving a stone age car, bad pieces, it's worn out, it gets you to where you need to go but you pray it does not break down, catch fire, or anything you can think of on the way. You want to be driving a new reliable car. A bad psu will always hinder a system, it does not matter how good you might think it is I would always recommend buying one that is worth the money and has been tested and is good. This is the one piece in a pc if you just drop 150+ on a new psu then you know for the next few years you have that reliable piece in your computer, and you know it will be able to power future upgrades. 25% of the time people have an issue with their pc it's a psu, that is saying something. PURCHASE A GOOD PSU. You will not regret it, especially when your pc does not burn down or you have a surge and a bad psu destroys your 1,000 dollar setup. This is my opinion but also fact.
