Cooler Master V750W PSU Review: Petite And Powerful
As stated before, my testing of PSUs is limited to basic readings and measurements. To that end I was actually limited in the amount of graphics cards I could connect to the unit, since the PSU only has two GPU cables, each cable consisting of two 6+2 pin connectors. I have three GPUs in my mining rig, which meant I could only use two GPUs to stress the power supply.
To that end I managed to get the PSU to draw 623W from the wall, which although is well below its capability, it still did it with ease and for a day of testing. I would have loved to have had an extra cable to properly put the PSU at the limit, but I guess it’s just extremely rare to have a 750W PSU with enough cabling to connect to 3 power hungry GPUs. Of note is that the PSU fan was constantly on, which means it does not have an idle/hybrid mode which turns the fan off during low loads. Regardless, the fan was still quite silent since its maximum speed at 100% is rated at 1800rpm, so it’s not at all louder than the fans on the GPUs, even when under load. Voltage regulation was splendid, with all the rails being well within specification for managing the load.
