Frequently Asked Questions
Is the C750 Bronze modular?
No. It is non-modular, so the cables are permanently attached. They are flat rather than round, which makes them easier to route and hide behind the motherboard tray.
The unit measures 150 x 86 x 140 mm, so it fits standard ATX power supply bays.
Can it power a modern graphics card?
Yes. It is ATX 3.1 and includes a native 16-pin (12+4) 12V-2x6 PCIe cable on a 650 mm lead, plus two 6+2-pin PCIe cables.
The +12 V rail delivers the full 750 W at 62.5 A, so no adapter is needed for a current-generation card.
How efficient is the C750 Bronze?
It is 80 PLUS Bronze rated. Measured at 115 V it reaches 86.0% at 10% load, 88.9% at 20%, 88.2% at 50% and 82.6% at full load.
Power factor correction is active at 0.96.
How loud is the fan?
A 120 mm PWM fan on a fluid dynamic bearing, rated to 39.92 dBA at its maximum 2,400 RPM while moving 64.4 CFM.
Because it is PWM controlled, it only approaches that figure under sustained heavy load.
What protections does it have, and what is the warranty?
Six protection circuits: over voltage, under voltage, short circuit, over temperature, over power and over current.
Bulk capacitors are rated to 105 degrees C, MTBF is 100,000 hours, and the unit carries a 5-year warranty.
