Good fit for
You should consider this power supply if you own an HP Pavilion Slimline S5000 system or another TFX SFF build. The specific connector layout matches legacy HP designs, making it a direct drop-in replacement. If your current unit has failed and you need a 300W TFX replacement, this listing offers a compatible option. The included warranty provides some peace of mind for older system repairs.

Who should skip it
You should look elsewhere if you have a modern desktop or gaming PC. This unit is not designed for high-performance graphics cards or multiple storage drives.

Key specs explained for this unit
300W Wattage
This power supply delivers a maximum of 300 watts of DC output power. This limit suits low-power systems that do not require dedicated graphics cards or heavy processing loads. You should verify that your existing components draw less than this total. It is ideal for basic office computers or media centers where energy efficiency and thermal management are priorities over raw performance.
TFX Form Factor
The unit uses the TFX standard, which is smaller than the common ATX format. This specific shape is required for HP Pavilion Slimline S5000 systems and other small form factor cases. You must ensure your computer case supports TFX dimensions. Using this unit in a standard ATX case is not possible without significant modification or an incompatible mounting setup.
24Pin+4Pin+2SATA Connectors
The connectors include a 24-pin main board cable, a 4-pin CPU power cable, and two SATA power outputs. This configuration supports standard motherboard and storage connections. You may find limited room for additional drives due to the low SATA count. Verify that your specific HP model uses this exact connector layout before purchasing to ensure physical compatibility with your internal components.
24-month Warranty
The manufacturer provides a twenty-four-month warranty covering defects or issues. This period offers more protection than the standard one-year coverage found in many generic replacement units. It provides peace of mind for long-term use in your system. If the unit fails within this timeframe, you can seek support for repairs or replacements according to the provider's specific terms and conditions.
Physical Design and Build Details
The listing specifies the unit measures 2.5 inches in width, 6.9 inches in height, and 3.3 inches in length. These dimensions confirm its TFX form factor. You need this exact size to fit into HP Pavilion Slimline S5000 cases or similar small form factor systems. The compact footprint allows for installation in tight spaces where standard ATX units cannot fit. You should verify your case clearance matches these measurements before purchasing.
Connectors are listed as a 24-pin main connector, a 4-pin CPU connector, and two SATA power connectors. This layout is tailored for specific legacy HP motherboards. You must ensure your system uses these exact connector types. The unit does not include PCIe or Molex connectors. If your build requires additional power cables, this supply may not support your configuration. The design prioritizes compatibility with the target HP models over universal flexibility.
The listing mentions a 24-month warranty. This provides a defined period for replacement if the unit fails. You should keep the original packaging for potential returns. The brand Lrker produces this 300W unit. According to the listing, it accepts AC input between 200 and 240 volts at 50 to 60 Hz. This input range suggests it is intended for regions with higher mains voltage. You should confirm your local power standards match these specifications to avoid electrical issues.
Setup and Daily Operation Guide
Installation begins by confirming your system matches the required form factor. This unit is a TFX power supply, measuring 2.5 inches in width, 6.9 inches in height, and 3.3 inches in length. You must ensure your HP Pavilion Slimline S5000 case or compatible small form factor chassis accepts these exact dimensions. The listing states compatibility with HP Pavilion Slimline S5000 systems, so you should verify your specific model number before proceeding.
Connecting the unit requires matching the provided connectors to your motherboard and drives. The power supply includes a 24-pin main connector, a 4-pin CPU power connector, and two SATA power connectors. You need to check that your motherboard has a 24-pin socket and a 4-pin ATX12V connector. Most modern low-power systems use these standards. You will connect your SATA hard drives or SSDs to the two available SATA ports. If your system requires more storage connections, you may need an external adapter, as only two are included.
Electrical setup involves checking your local power environment. The unit accepts AC input between 50 and 60 Hz at 200 to 240 volts. You must ensure your wall outlet provides stable voltage within this range. The maximum DC output is 300 watts. This limit defines your total system power budget. You should calculate the power draw of your CPU, motherboard, and drives to stay under this cap. Daily use is straightforward once installed. The unit operates silently under typical loads. You benefit from a 24-month warranty, which covers defects or damage. This support ensures long-term reliability for your specific HP setup without requiring additional monitoring tools or software.
Before You Buy This Unit
You must verify your HP Pavilion Slimline S5000 case accepts the TFX form factor. The unit measures 2.5 by 6.9 by 3.3 inches. Your existing motherboard connectors must match the 24-pin and 4-pin inputs. You also need to check if the two SATA connectors satisfy your drive requirements. This power supply is strictly for low-power office builds. It does not support dedicated graphics cards. If you plan to add a GPU, this unit will fail. You should compare it against higher-wattage TFX options if your system demands more power. Regular upkeep involves keeping vents clear of dust. Ensure the AC input matches your local voltage standards. This replacement fits only specific HP models. It is not a universal upgrade. Check your current power draw against the 300-watt limit. Exceeding this limit risks instability. This unit serves as a direct drop-in replacement for failed OEM units in compatible slimline systems. It offers no extra features beyond basic power delivery.
Check before you buy
- Confirm your case supports the TFX form factor.
- Verify motherboard accepts 24-pin plus 4-pin input.
- Check if two SATA connectors meet your needs.
- Ensure total system draw stays under 300 watts.
