Enermax Liberty Eco 400W PSU Review

Okay, so everything is connected. So far the PC has been up and running for about 25 minutes, with a solid 15 minutes of HD video rendering behind the scenes. Using the multimeter, I tested both of the 12v rails for any amount of fluctuation. On the +12V rail, I was getting between 12.10 to 11.72, which on the scales is very minimal to say the least. -12V rail gave me very nice readings as well, with -11.76 to -11.84 on the readings. This kind of fluctuation is normal, as there are always spikes and sags in a current, even DC current. On the +3.3V, I was getting a steady set of numbers, in the area of 3.36 to 3.31. The +5V line gave me mucho similar readings, with a beautiful 5.01 to 4.94 on average. Once again, these are nominal at best for a power supply. Very sturdy and steady numbers.

Using a power analyzer, I got accurate efficiency on the unit, which is rated at 80% to 85% efficiency under regular load. This is what I got:

Once again, powerful numbers, proving that this PSU does do exactly as it boasts. It can handle pressure while remaining at least 80% efficient. Impressive to say the least.

My final thoughts on this power supply are simple. If it does the job, and looks good doing it, then it’s either dependable hardware or Hayden Panettiere. Either way, I like what I see. The unit is sturdily constructed almost to the point of being weighty to say the least, but is very small which makes for easy install. It gave excellent numbers on all rails and lines and provided immense efficiency the whole time. I give this PSU two thumbs up, plus an extra one because I now have Hayden on the brain.

Would have been a 5 if not for the 24-pin only problem Performance 5 Does the job, stayed efficient, and looked good doing it. I love you, Hayden. Installation 5 Easy and breezy. It’s small and modular. A good combination. Value 4 It’s a little pricey, but worth it in the end for the efficiency and reliability. And the temp rating it beautiful! FINAL VERDICT: 5 out of 5 stars
