750 W Platinum ATX power supply

This Corsair HXi Series unit delivers 750 W of continuous power with 80 PLUS Platinum efficiency. The fully modular design uses a single 140 mm fluid-dynamic-bearing fan and meets ATX12V v2.4 and EPS 2.92 standards. C-Link monitoring allows software control of fan curves and rail configuration.

Suited to high-end single-GPU builds

Enthusiasts who want precise digital monitoring and the option to switch between single and multi +12 V rail modes will benefit from this platform. Systems that require more than 750 W or need a smaller form factor than 180 mm depth should consider other models.

750 W maximum power rating

The 750 W limit is the decisive figure; it defines the total output available for CPU, graphics and storage combined. If your planned load sits comfortably below this ceiling the HX750i provides headroom and Platinum efficiency, otherwise a higher-wattage unit is required.

Questions about this item

Will the 180 mm length fit in my case?

The unit is 180 mm long, so check your case specification for maximum PSU length before ordering.

Which cables must be connected during installation and what is the common mistake?

Connect the 24Pin main connector and only the modular cables your build needs; the frequent error is leaving a required PCIe or CPU cable unplugged.

When should the 140mm Fluid Dynamic Bearing Fan be cleaned or replaced?

Clean dust from the fan every 6 to 12 months; replace it if bearing noise appears or airflow drops noticeably.
