Value-Top Real 300W Output Power Supply VT-S300

There is no point in buying a PSU with way more potential power than you’ll ever use. A PSU calculator web page or software can be handy in finding a rough estimation of the wattage requirement of your build. However, it is not recommended to purchase a PSU just above your system’s power needs. A PSU delivers maximum efficiency with a 40 to 60 percent load. Besides, the performance of a PSU declines with time. So, you better opt for a PSU capable of taking you through your next few upgrades for multiple years. You must buy a PSU that fits inside your PC case. Higher-wattage PSUs tend to be a bit longer to house the additional power components they need. This may create issues with cable routing or even with placing other internal components inside the case.
