Inter-Tech HIPOWER SP-650 650 W Power Supply

The Inter-Tech HIPOWER SP-650 650 W is a power supply unit for desktop PCs providing up to 650 W of total power. It supports universal AC input from 100 to 240 V at 50–60 Hz and uses a 20+4 pin ATX motherboard power connector. The unit is finished in black and includes a 120 mm fan for active cooling. Cable lengths for the motherboard and PCI Express connectors are approximately 50 cm, offering flexibility during installation while maintaining a compact footprint and a weight of around 1.14 kg.

Advantages

The HIPOWER SP-650 delivers a stable 650 W output suitable for a wide range of mainstream PC configurations. With an efficiency rated at approximately 85% and active cooling via a 120 mm fan, the PSU balances performance and thermal management. The 20+4 pin ATX connector ensures compatibility with standard motherboards, and the 50 cm cable lengths for motherboard and PCIe connectors simplify routing inside typical ATX enclosures. The unit operates at a measured noise level around 35 dB, helping to keep system acoustics low.

Suitable for

• Home and office desktop PCs with mainstream components
• System builds requiring up to 650 W continuous power
• Upgrades where compact PSU size and standard connectors are needed

How to use

Install the Inter-Tech HIPOWER SP-650 into a compatible ATX or microATX case following the case manufacturer’s instructions. Connect the 20+4 pin ATX cable to the motherboard main power socket and route PCIe power connectors to the graphics card or other PCIe devices as required. Ensure the AC input cable is connected to a properly grounded mains outlet that supplies 100–240 V at 50–60 Hz. Verify that all connectors are seated securely and that airflow around the 120 mm fan is not obstructed before powering on the system.

Recommendations

For reliable operation, use the PSU within its rated power envelope (up to 650 W) and maintain adequate case ventilation. Keep the unit free of dust and ensure intake/exhaust paths for the 120 mm fan are not blocked. When building or upgrading a system, check total component power draw to confirm this 650 W supply meets peak and continuous requirements.
