- Dual 6+2 pin PCIe connectors for GPU upgrades
- Compact 5.9 by 3.2 by 2.6 inch TFX size
Who it fits
Good fit for
You should buy this power supply if you own a Lenovo ThinkCentre M310, 410, 415, 510, 610, or 710 desktop. It is also suitable for M920s and M720t models. The 310W limit fits systems with modest GPUs like the GTX 1050 or 1060. The three 12V rails provide stable power for the CPU and motherboard. You need this unit if your original PCJ007 or SP50H29573 part failed. It is a direct replacement for users who need the specific 10-pin interface.
Who should skip it
You should skip this unit if your computer requires a standard ATX 24-pin connector. It will not fit standard desktop cases. Do not buy it if you plan to install a high-end graphics card drawing more than 90W. The 310W total output is insufficient for gaming rigs with powerful GPUs. You also need to check your current part number. If your system uses a different Lenovo part, this unit will not work. It is strictly for compatible Lenovo TFX models only.
Verdict: This is a correct replacement for specific Lenovo TFX desktops needing the 10-pin connector. It fits budget builds with modest graphics cards.
Key specs explained for this unit
Wattage: 310W
This rating defines the maximum total power the supply can deliver to your components. It suits entry-level Lenovo desktops with modest GPUs. You must ensure your CPU and graphics card draw less than this limit. Exceeding it may cause instability or shutdowns. Check your system’s power requirements before buying to avoid compatibility issues.
PCIe Connector Type: 6+2pin
This connector type allows flexible attachment to modern graphics cards. The 6+2pin design splits into a 6-pin or 8-pin connector. This ensures you can power GPUs that require either standard. It provides a secure fit for your video card. Verify your graphics card uses this standard before purchasing to ensure proper installation.
Form Factor: TFX
TFX indicates a slim, compact physical size designed for small form factor cases. This supply fits specific Lenovo M-series desktops. It is not interchangeable with standard ATX or SFX units. You must measure your case space and mounting points. Using the wrong form factor will prevent installation. Confirm your case supports TFX before proceeding with this upgrade.
Warranty: 1 Year
This warranty period covers manufacturing defects for one year. It offers limited long-term protection compared to higher-end units. You should plan for potential replacement within this timeframe. It is suitable for budget builds or temporary fixes. Consider the risk of failure after the warranty expires. Factor this into your decision when comparing other power supply options.
Physical design and build details
According to the listing, this LXun unit measures 5.9 by 3.2 by 2.6 inches. It weighs 1.79 pounds. The compact TFX form factor allows it to fit into Lenovo ThinkCentre M series cases like the M310 and M415. You should verify your case supports this specific size before purchasing. The small footprint is necessary for the slim chassis of these business desktops.
The listing does not specify the outer casing material or internal finish. It only confirms the unit passes strict quality inspection before leaving the factory. This suggests a standard industrial build rather than a premium aesthetic one. You are buying a functional replacement part, not a showcase component. The focus is on fitting the slot and delivering stable power.
Controls are minimal. The unit uses a passive cooling design. The fan only rotates when the CPU reaches a certain temperature. Higher CPU temperatures result in faster fan speeds. This means the power supply runs silently during light workloads. It only becomes audible under heavier loads. This temperature-controlled approach reduces noise in office environments where these desktops are commonly used.
Setup and everyday use details
Installing this LXun unit requires matching its 10-pin motherboard connector to your Lenovo desktop. The listing specifies compatibility with models like the M310, M410, and M510 ThinkCentre series. You must verify that your existing power supply interface matches this connector exactly. The product data notes that having the correct computer model in the list is not enough if the physical interface differs. This unit replaces part numbers such as PCJ007 and SP50H29573. Ensure your system uses one of these identifiers before proceeding with the swap.
Once installed, the power supply operates with a temperature-controlled fan. The fan does not run constantly. It only activates when the CPU reaches a specific thermal threshold. Higher CPU temperatures result in faster fan speeds. This design aims to reduce noise during light workloads while providing adequate cooling under load. The unit supports 100-240V AC input, making it suitable for various global power standards.
In daily use, the three independent +12V rails each provide up to 18A. Their combined output must not exceed 310W. This configuration supports modest graphics cards, including the GTX 1050, 1060, 1070, and 1080, which typically draw around 90W. You should ensure your total system power draw stays within the 310W limit. The unit includes two 6+2-pin PCIe connectors for graphics power and two 4-pin connectors for CPU power. This setup handles basic upgrades for these specific Lenovo desktops without requiring additional adapters.
Before You Buy This PSU
Before you buy, verify that your Lenovo desktop case accepts the TFX form factor. The listing confirms compatibility with ThinkCentre M series models like the M310, M410, and M510. You must check that your current power supply uses the same 10-pin motherboard connector. Mismatched interfaces will prevent installation, even if the model number appears in the description. This unit supports modest graphics card upgrades up to 90W, such as the GTX 1060 or 1080. Ensure your CPU and GPU combined draw remain under the 310W limit. The fan operates based on CPU temperature, so keep your case vents clear for proper airflow. Regularly dust the intake filters to maintain cooling efficiency. This supply fits alongside other TFX options for users needing a direct replacement for prebuilt Lenovo systems. It is not suited for standard ATX cases. Confirm your existing power supply’s wattage and connector type before ordering to avoid compatibility issues.
Check before you buy
- Verify your Lenovo case supports the TFX form factor.
- Confirm your motherboard uses the 10-pin power connector.
- Check that total system draw stays under 310W.
- Ensure your GPU power requirement is under 90W.
