Testing Antec NeoHE 430W




Like the Corsair, Antec's NeoHE is made by Seasonic. And just as I did with the Corsair, I removed the modular interface so I could access it more easily with the DMM. The biggest difference between the two is the cables. Not just that the Corsair, like the Ultra, has a "ribbon-style" cable (what Ultra calls "FlexForce") while the Antec has a traditional sleeved wire; but the wires on the Corsair are one to one. The Antec connectors are 6-pin, similar to a PCI-e connector, but supply 5V and 3.3V as well as 12V and ground. This way, any peripheral can plug into any connector on the power supply. So, as far as PCI-e connectors go, instead of having three 12V conductors and three grounds, we have two 12V conductors and two grounds. Will this affect the voltages?



The Antec starts off even lower than the last two power supplies and drops under load more than the Corsair, but not as much as the Ultra. The drop in voltage at the connectors was no more than .02V, which puts it right in between the other two power supplies. But at .15V, there was more of a drop in voltage in the cables than the other two modular power supplies.

Let's see how this compares to a couple power supplies that do not have modular connectors...
