Who it fits
Good fit for
This power supply suits owners of older Dell Optiplex desktops who need a reliable replacement. If your system uses models like the 390, 790, 990, or 3010, this unit matches the required 250W specification.

Key specs for YEECHUN PSU
Wattage: 250W
This rating defines the maximum power the unit can deliver to your system components. It is suitable for basic desktops with integrated graphics and standard office peripherals. If your Dell Optiplex relies on low-power internal hardware, this output level maintains stable operation. You should compare this against your original unit to ensure the replacement meets the baseline energy needs of your motherboard and drives without causing instability.
Warranty: 12 months
This coverage period protects your purchase against manufacturing defects for one full year. It offers a standard safety net for replacement parts that lack the long-term support of original equipment. If the unit fails within this timeframe, you can seek a replacement or repair. This duration helps mitigate the risk of buying a third-party component, giving you peace of mind during the initial usage phase of your refurbished system.
Compatible Part Number: CYY97, 7GC81, HY6D2, WX9P8, 6MVJH
These identifiers allow you to cross-reference the listing with the label on your existing power supply. Dell systems often use multiple part numbers for similar units across different production batches. Verifying these codes ensures the replacement fits your specific motherboard connector layout and form factor. You should check your current unit against this list to confirm compatibility before installing the new hardware in your desktop chassis.
Compatible Model: L250NS-00, PS-5251-08D, D250AD-00
These model numbers represent specific hardware revisions of Dell power supplies. Matching these exact identifiers guarantees that the physical dimensions and electrical pinouts align with your system. Using a mismatched model can lead to connection issues or insufficient power delivery. You must verify your current unit matches one of these models to ensure a seamless swap that restores your computer to full working order without additional modifications.
Design and build details
The listing states that the unit is constructed from high-quality durable materials. It notes that strict quality control standards are applied during the build and testing phases. The manufacturer claims the build is better than the original equipment manufacturer version. These material choices suggest a focus on longevity for a replacement part. You should expect a standard industrial finish typical of internal desktop components. There is no mention of premium aesthetics or external design features, as this is an internal power supply unit. The construction is intended to fit securely within the chassis of compatible Dell systems.
Size and weight details are not provided in the published specifications. The listing does not describe the physical layout, cable routing, or connector types beyond model compatibility. It does not mention any external controls, switches, or displays. You must rely on the listed compatible model numbers to verify physical fitment. The product is designed to replace specific OEM units like the L250NS-00 or PS-5251-08D. This means the form factor matches those legacy Dell Optiplex desktops. You should check your current power supply model carefully before purchase. The design is purely functional, aimed at restoring power to systems like the Optiplex 390, 790, or 990.
