Power and Connector Differences
Max Power Output
The LXun 310W Lenovo TFX Power Supply delivers 310 watts of continuous DC output, while the LXun 220W PC8044 PSU provides 220 watts. This 90-watt difference matters significantly for systems with discrete graphics cards. The 310W unit supports 90W GPUs, whereas the 220W unit is limited to basic office tasks. You must choose based on your GPU requirements. Higher wattage allows for more robust performance in compatible machines.
Input Voltage Range
The LXun 220W PC8044 PSU accepts 100-127V AC input, restricting it to specific regional power standards. In contrast, the LXun 310W Lenovo TFX Power Supply supports a global 100-240V AC input range. This wider range makes the 310W unit more versatile for international use or unstable power environments. You do not need a voltage selector switch with the 310W model. This flexibility is a key advantage for travelers or global deployments.
Motherboard Connector
Connectivity differs between these two units. The LXun 310W Lenovo TFX Power Supply uses a 10-pin motherboard connector, designed for specific Lenovo TFX systems. The LXun 220W PC8044 PSU uses a standard TFX connector compatible with HP Pavilion models. You cannot swap these connectors without ensuring your motherboard matches. The 10-pin design on the 310W unit is specific to Lenovo hardware, while the 220W unit fits HP OEM cases.
Graphics Card Support
The LXun 310W Lenovo TFX Power Supply includes two 6+2-pin PCIe connectors for graphics cards. The LXun 220W PC8044 PSU does not list dedicated PCIe connectors in its specifications. If you plan to upgrade with a discrete GPU, the 310W unit is the only viable option. The 220W unit is intended for integrated graphics only. You need the extra connectors and power headroom for any GPU upgrade.
Physical Dimensions
Both units are TFX form factor replacements with similar heights and widths. The LXun 220W PC8044 PSU measures 6.89 inches in length, while the LXun 310W Lenovo TFX Power Supply is 5.9 inches long. The 310W unit is more compact in length, which may fit tighter cases better. Both share a 2.6-inch height and roughly 3.2-inch width. You should verify case depth compatibility, though the 310W model offers a slight size advantage.
