Who it fits
Good fit for
You should consider this power supply if you are building or upgrading a small form factor PC, such as a Dell Inspiron 530s or similar MicroATX slimline case. The 300W capacity is sufficient for low-power components like integrated graphics and basic CPUs. The TFX form factor ensures physical compatibility with tight chassis designs. If you need a straightforward, reliable replacement unit with a warranty, this model fits those requirements well.
Who should skip it
You should look elsewhere if you require high wattage for gaming or heavy workloads, as 300W is limited. This unit lacks multiple high-power connectors for modern GPUs. The 80mm fan may not provide sufficient cooling for high-end components under heavy load. Users needing active PFC auto-switching for international travel should verify compatibility with their specific regional voltage needs, as this feature is included but may require manual adjustment.
Verdict: This is a practical, spec-driven option for small form factor systems with low power demands. It offers reliable basic performance within its physical constraints.
Key specs for this PSU
Wattage: 300W
This value indicates the maximum power the unit can deliver to your components. A 300W output suits systems with low-power CPUs and integrated graphics. It is ideal for office PCs or basic media centers. You should ensure your total system draw stays below this limit. Higher wattage units handle gaming rigs or multiple drives better. Check your component requirements before choosing this capacity.
Form Factor: TFX
TFX is a specific physical size for power supplies, distinct from the common ATX standard. This form factor fits into small form factor cases, such as slim MicroATX chassis. It allows for compact builds where space is limited. You must verify your case supports TFX units before buying. Using the wrong form factor will prevent installation. This size is common in Dell Inspiron slimline desktops.
Fan Size: 80mm
The cooling fan measures 80mm in diameter. Smaller fans often spin faster to move air, which can increase noise levels. This unit uses an 80mm fan to keep internal temperatures stable. You may notice more acoustic output compared to larger 120mm fans. However, it provides necessary airflow for the compact enclosure. Consider your noise tolerance if you place the case near your desk.
Dimensions: 6.89 x 3.35 x 2.56 inches
These measurements define the physical footprint of the power supply. The length is 6.89 inches, with a height of 3.35 inches and width of 2.56 inches. You need to check your case interior to ensure this size fits. TFX units are generally shorter than ATX units. Precise dimensions help you plan cable routing and component placement. Verify clearances before installation to avoid physical conflicts.
Design and Build Quality
The listing describes the BackPlanePro 300W TFX Power Supply as a compact unit with a grey finish. Its physical dimensions are 6.89 inches in length, 3.35 inches in height, and 2.56 inches in width. The unit weighs 3 pounds. These measurements define its TFX form factor. This specific size allows the power supply to fit into MicroATX slim cases. You will find this design particularly useful for small form factor builds where space is limited. The compact chassis ensures it does not obstruct other components inside the case.
The listing highlights an 80mm fan for cooling. This fan size is smaller than the standard 120mm fans found in larger power supplies. The smaller fan helps maintain the unit’s slim profile. The listing claims this fan keeps the PSU running at peak performance. Active PFC is also listed as a feature. This technology adjusts to input voltage automatically. It helps improve efficiency across different power sources. The model number provided is LYSB00CXAUQJK-CMPTRACCS. According to the listing, the build quality is intended to be robust. This suggests the internal components are designed for reliable output. The one-year warranty is also part of the build specification. This warranty period covers defects in materials and workmanship. It provides a baseline for product longevity. You should consider these specs when planning your case compatibility.
Setup and everyday use
Installing this unit requires a case that supports the TFX form factor. The listing specifies it works with MicroATX slim cases, such as the Dell Inspiron 530s or 531s. You must verify your chassis has the proper mounting points for a 6.89-inch long, 3.35-inch high, and 2.56-inch wide power supply. The 80mm fan size is standard for this form factor, ensuring compatibility with most small form factor airflow designs. Once mounted, the active PFC feature automatically switches to match your local voltage. This means you do not need to manually adjust settings when moving the PC between regions with different power standards. The unit delivers 300W of continuous power. This output is sufficient for systems with low-power CPUs and integrated graphics. In daily use, the 80mm fan provides cooling to maintain peak performance. The listing notes the fan is designed for silent operation. This implies lower noise levels during standard tasks like web browsing or document editing. The power supply is built to provide robust output for your entire system. You can rely on the 300W limit for basic computing needs. The one-year warranty covers manufacturing defects. This gives you a standard period of protection for your investment. The grey finish blends with most internal components. The 3-pound weight adds minimal load to your case structure. This setup is straightforward for users building or upgrading small form factor PCs. It replaces older units in compatible Dell systems without requiring complex modifications.
Before You Buy This PSU
This unit is a replacement part for specific small form factor systems. You must verify your case supports the TFX form factor before purchasing. The listing notes compatibility with Dell Inspiron 530s and 531s slimline cases. Ensure your motherboard and components do not exceed the 300W limit. Systems with discrete graphics cards or high-end CPUs will likely draw more power than this supply can provide. You should check your current power draw against this maximum. The 80mm fan provides cooling, but you need adequate airflow in your chassis. Dust accumulation can affect performance over time. Regular cleaning of the fan intake helps maintain peak operation. This option fits into the broader market of compact power solutions. It serves users who need a direct replacement for legacy or specialized slim cases. It is not suitable for standard ATX cases or high-performance gaming rigs. Confirm your physical space and power requirements align with these specifications.
Check before you buy
- Verify your case supports the TFX form factor.
- Check if your system power draw stays under 300W.
- Confirm compatibility with Dell Inspiron 530s or 531s if applicable.
- Ensure your chassis allows for 80mm fan airflow.
