Description
A basic PSU for simple PC setups
The Inter-Tech SL-500 TBO is an entry-level 500W power supply mainly intended for office PCs, light home systems, or older desktop replacements. It is not designed for gaming PCs with powerful GPUs, but rather for stable everyday computing.
It follows the ATX standard and delivers basic but functional power distribution for standard components.
500W power for light usage
With a maximum output of 500W, this PSU can handle:
- Office PCs
- Low-power CPUs (Intel i3 / Ryzen 3 or older systems)
- Integrated graphics systems
- Basic storage setups
Pout=500 WP_{out}=500\,\text{W}
👉 Important: it is not recommended for modern gaming GPUs like RTX 3060 and above.
Basic ATX design and compatibility
The SL-500 TBO follows an older ATX design standard and includes:
- 20+4 pin motherboard connector
- CPU 4+4 pin connector
- SATA + Molex power connectors
This makes it compatible with most older and basic PC systems.
Cooling and noise level
The PSU includes a:
- 120mm fan
- Automatic fan control
- Low noise operation (~19–25 dB)
It is designed for quiet office use rather than heavy load performance.
Efficiency and certification
The SL-500 TBO:
- Does not have 80+ certification
- Uses basic efficiency design
- Focuses on cost reduction over performance
This means it is less efficient compared to modern Bronze or Gold PSUs.
Protection features (basic safety)
It includes essential protections:
- OVP (Over Voltage Protection)
- OCP (Over Current Protection)
- OPP (Over Power Protection)
- SCP (Short Circuit Protection)
- UVP (Under Voltage Protection)
These help prevent damage in normal usage scenarios.
Important real-world advice (very important)
This PSU is widely considered:
✔ OK for very basic PCs
✔ Fine for office / internet use
✔ Budget replacement PSU
But:
