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.

True Wattage Guarantee

The wattage you see isn’t always the wattage you get. Some brands tweak tests to achieve great wattage ratings, but in reality, they deliver much lower maximum wattages. Don’t be fooled by wattage tricks.
