Τροφοδοτικό Inter-Tech HIPOWER SP-550 550 W

The Inter-Tech HIPOWER SP-550 550 W power supply unit provides stable DC output for desktop PCs and compact systems. Designed for general-purpose computer builds, it accepts a wide AC input range of 100–240 V at 50–60 Hz and delivers up to 550 watts of total power. The unit features a 20+4 pin ATX motherboard connector, a 120 mm cooling fan and an active cooling system engineered to maintain operating temperatures while producing low acoustic levels (approximately 35 dB). Its compact metal housing (150 x 140 x 86 mm) and black finish make it suitable for many standard PC cases.

Advantages

The HIPOWER SP-550 combines a moderate 550 W capacity with an efficiency rating around 85%, offering a balance between power delivery and energy use for mainstream builds. A 120 mm fan with active cooling reduces thermal stress on internal components while keeping noise levels low. Compact dimensions and a lightweight design simplify installation in mid-tower and small form factor cases. Standard 20+4 pin ATX compatibility ensures straightforward connection to common motherboards.

Suitable for

• Office and home desktop computers with integrated graphics or single mid-range GPU
• Compact or mid-tower system builds that require a standard ATX connector
• System upgrades where existing power headroom of up to 550 W is sufficient
• Quiet environments where a low-noise PSU is preferred

How to use

Install the power supply into a compatible PC chassis following the case manufacturer’s instructions and secure it with the supplied screws. Connect the 20+4 pin ATX connector to the motherboard main power socket and attach any additional peripheral connectors required by your components. Ensure the AC mains input is within the specified 100–240 V range and use a properly grounded mains cable. After connections are verified, power the system on and monitor voltages and temperatures during the first boot to confirm stable operation.

Recommendations

Place the PC in a well-ventilated location and maintain unobstructed airflow around the PSU fan intake and exhaust. Keep dust accumulation to a minimum by periodic cleaning with compressed air and ensure the mains cable and connectors remain in good condition. For systems with high-power GPUs or heavy overclocking, consider a higher-capacity unit to preserve headroom and ensure long-term reliability.
