Six Invaluable Online PC Building Tools
Comparing CPUs and Calculating Power Needs
CPUBoss is a relatively new PC builder resource, but it’s already made a name for itself. The slick UI, easy to use filters and parameters, and beautiful review graphics make it a must-use when you’re deciding between that Core i7-3770K and Core i5-3570K.
Along with setting a price range ($300 or less is a good starting point), CPUBoss also lets you compare or filter by brand, purpose (desktop or server), or look at everything first, then drill down from there. The simple yet effective CPU reviews score on multi- and single-core performance, overclocking friendliness, and value.
4. eXtreme Power Supply Calculator
Goofy name aside, the eXtreme Power Supply Calculator (XPSU for short), specifically the free “Lite” version, is an invaluable tool for determining how much power you need. Simply plug in your other hardware, case fans included, and XPSU spits out a reference number. Overshooting needs on a power supply is a common mistake, and XPSU can keep you from dropping serious coin on a 1,000W monstrosity when a 750W unit will get the job done.
