Power Output:

• 550W continuous power output, offering more capacity compared to lower-wattage models like the XPS450R.
• This is suitable for systems with moderate to mid-range components, such as a discrete GPU, multiple hard drives or SSDs, and a standard desktop CPU.

Form Factor:

• ATX form factor, compatible with most ATX cases.
• It’s designed to fit into the standard power supply slots of typical desktop cases.

Efficiency and Reliability:

• While not necessarily 80 Plus certified, it is built to handle a higher load with more efficient voltage regulation and better stability compared to lower-wattage models.

Cooling:

• The XPS550N has an internal cooling fan. Given its higher wattage, the fan may be slightly louder under load but should still be relatively quiet for the type of system it powers.

Connections:

• 1 x 20+4 Pin ATX main power connector
• 1 x 4-pin 12V CPU power connector
• 1 x 6+2 PCIe power connector (for graphics cards that require PCIe power)
• 2 x SATA power connectors
• 3 x 4-pin Molex power connectors
• 1 x Floppy drive connector (though this is becoming less common)

Design and Build:

• The design is typical of entry-to-mid-level power supplies, with a focus on providing enough stable power for a standard desktop without being overly expensive.
