Other Power Supply Units
Conventional PSUs use multi-rail technology which basically combines cheaper and lower wattage PSUs into one single PSU to generate a higher total wattage. However, smaller rails have lower maximum wattages so left over wattage on individual rails become too small to handle major components and gets wasted.
Not enough actual wattage - Even though there is technically 50 Watts of power remaining, none of the rails have more than 25W to handle adding a 50W component.

Easyrail™ Power Supply Units
PSUs with EasyRail™ Technology give you one continuous rail of power covering the total maximum wattage. What this means is that no matter how many devices you have, high or low power, they can easily stack until it reaches the full maximum wattage. With EasyRail™ technology you can maximize the potential of your PSU with ease.
Exactly enough actual wattage - Of the 50 Watts of power that you expect to be remaining, all 50W is actually available to easily handle adding a 50W component.
