The current capability being 8 A and the actual load being 2-3 A is not going to be a problem if the regulator circuit is at all well designed. If you just designed a voltage divider and told your boss it was a voltage regulator, it could lose regulation at 7.9 A load.Īs the comments point out, there are numerous other considerations that determine whether your power supply is appropriate.
I will add data to your account for the test and all you will need to provide is the day and time you disconnected devices/turned off wi-fi, then the day and time you re-connected. But if you made a very very bad design, it could possibly lose regulation at 1 A or higher. The easiest thing we can do to start is do the data test again, you won't need to do it for 24 hours (more than 5 hours is acceptable, some prefer to do it overnight). At the same time, all the better motherboards (AsRock X470 Taichi, ASUS.
The same goes for be quiet Straight Power 11 - 650W has one 4+4pin cable, 750W has one 'P8' (8pin I suppose) and one 'P4+4' connector. An 8 A supply could be designed that does not lose regulation (meaning the output voltage goes out of spec) under low currents down to a few mA. Seasonic Focus Plus Gold/Platinum 650W also has only one 4+4pin cable, to have two 4+4pin cables you need to buy at least a 750W PSU. This is entirely down to the design of your power supply circuit. the devices are not drawing maximum current? When the system is idle, will this be an issue, i.e. This will generally allow the supply to run cooler, and it also allows for the possibility you underestimated your actual needs. It is generally a good idea to design a constant voltage power supply with more current capability than you need.
