All right, let’s fire up the load tester and all of the usual test gear so we can see how this puppy performs. I’ll be using all the same test gear used with the other two models, so there won’t be any doubt how this whole product line performs.
|NZXT E650 – STANDBY Load Tests|
|Test #||+5VSB||DC Watts/
Starting with the weekend categories and styling… oops, I accidentally forgot to turn off Doug DeMuro’s YouTube channel. Sorry about that. We’ll start with the usual standby tests.
Efficiency is above average on this unit, but nothing groundbreaking. Just like the other two units in this series. Voltage regulation is an excellent 1.4%. Let me just fire up CAM here and we’ll get the main tests done.
|NZXT E650 – Cold Load Tests|
|Test #||+3.3V||+5V||+12V||DC Watts/
|Progressive Load Tests|
It will come as a shock to nobody that this unit performs really well. We’ve come to expect that from units that come from the Seasonic factory.
Gold efficiency was no big problem today with most load levels clearing the target with no trouble. The unit does have a little struggle going on in test three, but is well inside the 1% figure I want to see to allow a pass there.
Once again, this platform seemed like it was in a real big hurry to get the fan moving, and by test five it was running wide open. I commented on the 850W review that the CAM software can only do so much to tame the fan, and that was the case here as well. You can set custom fan curves, but only to a certain load level. After that point, you get no say at all in how fast the fan runs. On the first crossload test, the fan kept cycling on and off, which is why you see the 0-630 numbers in the chart above.
It goes without saying that we expect Seasonic originated units to absolutely nail the voltage load regulation numbers these days, and this unit was keen on not disappointing us. On the 3.3V rail, keeping in mind these numbers now include both crossload tests, I see 0.52%. The 5V rail managed 0.40%. Finally, the star of the show was the 12V rail at 0.25%. That gives us a three output average of 0.39%, which is right at mythic level once again. Can’t ask for anything more.
