## Long description

The Chieftec CSN-450C is a compact SFX power supply designed for small-form-factor desktop PCs. It delivers up to 450 W of continuous power with wide-range AC input (100–240 V, 47–63 Hz) and meets 80 PLUS Gold efficiency standards. The unit is fully modular and comes in a black finish with an active 80 mm cooling fan to maintain stable temperatures during normal operation.
Advantages
The CSN-450C offers high energy efficiency with an 80 PLUS Gold rating and a reported efficiency around 90%, reducing wasted heat and lowering power consumption. Its fully modular cabling simplifies installation and cable management in compact cases, while the SFX form factor provides compatibility with small builds. The included 80 mm fan provides active cooling without significantly increasing the unit’s footprint.
Suitable for
Small-form-factor desktop PCs and compact HTPC builds
Systems that require a fully modular PSU for neat cable management
Energy-conscious builds seeking higher efficiency (80 PLUS Gold)
When it may not be suitable
This 450 W unit is intended for modest to moderate power requirements; it may not be suitable for high-end gaming rigs with multiple graphics cards or systems with heavy overclocking that demand significantly higher wattage. Also, while SFX fits many compact cases, some larger cases or specialized enclosures may require an ATX-sized PSU.

How to use
Install the CSN-450C into a compatible SFX or SFX-to-ATX adapter bay following your case and power supply manuals. Connect the 20+4 pin connector to the motherboard and attach only the modular cables required for your components to keep cable clutter minimal. Ensure the PSU intake and exhaust areas have adequate airflow and connect to mains power within the 100–240 V, 47–63 Hz range. Power on the system and monitor voltages during initial use to confirm stable operation.
What to consider before purchase
System power requirements — verify that 450 W covers CPU and GPU peak loads
Case compatibility — confirm your case supports SFX or use an adapter if needed
Cabling needs — check included modular cables match your component connectors
Cooling and ventilation in your case to ensure proper PSU airflow
Usage recommendations
For compact builds, pair the Chieftec CSN-450C with a single mid-range GPU and a mainstream CPU to stay within its power envelope; use only the modular cables you need and maintain case airflow to maximize efficiency and longevity.
