Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rails, we see 2% regulation across the board. 12V4 faired the best with a total drop of .13V from start to finish while 12V2 did the worst and showed a drop of .25V. The 5V rail also stayed within 2% voltage regulation and displayed a total drop of .10V. Moving towards the 3.3V rail, we see that regulation was again within 2% with a total voltage drop of .08V.


DC output quality was great from start to finish and just what we had hoped for. Starting out, we saw a ripple of 18mV on the scope. This slowly increased as we stepped up the loads. By the time we had reached around 50% load, the unit ripple had crept up to 21mV. Under full load, we saw that the noise on the 12V rail had crept up to 34mV.

The Antec EarthWatts 650W power supply is rated for 80Plus Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the EarthWatts 650W performed just as it should have, even if things were very close at the end.

Yep! But I do wonder how many people are going to be looking for a PSU.

This might be a dumb question but why does that PSU cost so much? Because of the platinum certified?

What would sway someone to get this and not say, a corsair 650 tx or a seasonic psu?

Not trying to thread crap but seeking information since there are no reviews on Newegg on this.

Thanks and GLWS

Yes I do believe it's because it's one of the most efficient PSU's out there up to 92%.
I think it may be newly released?
I'll probably price drop to 80$ shipped.
