These items draw a lot of electricity, causing problems with computers. Your risk of problems is even greater if you use a UPS because the UPS will react to the voltage changes caused by frequent cycling of this equipment. This runs the UPS battery down, reducing your protection. You may have lower voltages than normal. You should directly connect all equipment to a receptacle.
Extension cords reduce available voltage.
