I'm currently using a Xigmatek NRP-PC702 700W, by far the oldest component in my PC (5-6 years), and i'm wondering if I should be worried at all about reliability when it comes to overclocking. Based on reviews the unit itself seems solid enough by 2010 standards, I'm mostly just concerned about it's age. Thanks in advance for any advice.
