Installation & Testing
Getting the HX750i in your system should be simple enough. This is a completely modular power supply so you only use the cables that you need. I would suggest connecting your cables before you mount the power supply in your system.
We will be testing the HX750i in our X79 system which is made up of the following components.
Processor: Intel Core i7-4960X Extreme Edition
Motherboard: ASUS P9X79 Pro
Video Card: Sapphire R9 280X Toxic
Memory: 16GB Kingston 10th Anniversary
Power: Corsair HX750i
Storage: 750GB SATA II Drive
Cooling: Scythe Mugen Max
Case: Cooler Master Cosmos II with 5 fans
We will be using OCCT to test this power supply. Initial spot checks on the 3.3V, 5V and 12V rails were 3.27V, 5.04V and 12.1V respectively. We will be running OCCT’s power supply test for 1 hour to stress test the power supply. Below are the results.
3.3V
5V
12V
All of the rails showed some “ripple” as you can see in the graphs above, but the 12V rail was more solid than the rest. For those wondering the voltage regulation on each of the rails are as follows: 3.3V: 2.14%, 5V: 1.58%, 12V: 1.65%.
