In today’s world everybody wants it all: Efficient & stable power for her or his PC and without hearing it running, all at an affordable price!

Being certified as 80 PLUS is quite a must-have to minimizing the electricity bill, but having ENERMAX’ patented SpeedGuard fan control with the acknowledged lowest noise profile worldwide, won’t let you hear the 12cm ball-bearing fan working, while saving your money. Likewise, the patented AirGuard inlet reduces air-turbulences furthermore. The FUTURE ready! 12P socket offers upgradability for possible future CPU or GPU connectors. Being in a true ATX standard housing of only 140mm length let it fit even in most HTPC systems. An 115% capacity transformer and a special version heavy-duty Japanese main capacitor keep the output stable even at full load, while TRIPLE AC + DUAL DC EMI Filter keep the output power cleaner than others, making it 24/7 @ 40°C ready!. The 400 & 500W models with two 6+2P PEGs can power one of all available highest-end graphics cards and the 620W with four 6+2P PEGs even two.

But LIBERTY ECO’s key feature is safety. As the world’s first PSU series, it obtains a dual UVP (under voltage) protection by having dedicated AC UVP (brown-out protection) & DC UVP for output integrated in the industry-leading SafeGuard function with additional OCP, OPP/OLP, SCP, OTP and OVP protections.

	While there are many power supplies that have much higher capacity, and are much more flashy, sometimes what we need is something that just works. The ECO80+ does just that, and without any complaint. There is no doubt that this unit should be more than sufficient for any single-GPU system on the market today. Add on top of that the very cool and quiet performance of this unit, and the vast majority of users should be very pleased.
	While the Enermax Liberty Eco 620W is sort of being positioned as a value unit it shares a lot of things in common with the MODU82+ and as such we have to compare it to that unit. When we do compare the two units we find that the Liberty Eco does not seem to really have had all that much shaved off of it to reduce cost for its role as a value unit.
	The new Liberty ECO 500W power supply from Enermax delivered very good voltage regulation with clean outputs and excellent efficiency. On top of that, the Liberty ECO 500W proved to be one of the quietest PC power supplies we have tested to date in this power range. Throw in support for high-end graphic adapters, a compact chassis that will fit in most any ATX style case, and plenty of peripheral connectors and you have a very attractive PSU package! These new power supplies from Enermax should be of particular interest to anyone building a HTPC or silent PC.
	My first Enermax turned out to be a unit that is sure to please anyone out there looking for a good midrange modular unit. It's very stable, very efficient, and provides extremely clean power at the outputs.
	We were really impressed by Enermax Liberty ECO 500 W, and it is always good to see a manufacturer improving their product line. Liberty ECO series has absolutely nothing to do with the previous Liberty DXX series: it uses a completely different internal design that provides a far higher efficiency.
	Nós ficamos realmente impressionados com a Enermax Liberty ECO 500 W. É sempre bom ver um fabricante aumentar a qualidade de sua linha de produtos. A série Liberty ECO não tem absolutamente nada a ver com a série antiga Liberty DXX: ela usa um projeto interno completamente diferente que oferece uma eficiência muito maior.
