500W to 550W: 12 Power Supplies Compared
Last month, we reviewed 20 power supplies ranging from 300W to 450W. These are great for entry-level or even midrange systems, with optimal efficiency typically falling in the 100W to 200W range. Today, we have 12 more power supplies on our test bench, this time targeting a slightly higher range of 500W to 550W. This particular sector is where we really start to see higher quality designs and better technologies, in part because these tend to be more expensive PSUs.

Enermax Liberty Eco 620W
Summary

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. There are a couple of things I think Enermax needs to look into yet, like the ineffective zip tie mount on the PFC coil, but really I don't see any reason why you shouldn't just go ahead and buy one right now. Go forth and spend, loyal readers!

The Good:

* very efficient
* very stable regulation
* no tan glue of death
* lots of SATA connectors
* very quiet
* kept working at full power well above 40 degrees

The Bad:

* 76 degrees and no overtemp shutdown

Reviews - Enermax Revolution 85+ 1050W



As you can see by the picture above, I have the latest and greatest design from Enermax in my hands today, the Revolution 85+. This design promises high power at extremely high efficiency, something that is not always easy to do. My review sample weighs in at 1050W, making it the second most powerful of the four Revolution models, with only the 1250W model above it.

The 85+ in the name seems to suggest what the folks at 80 Plus have found factual - this unit is supposed to start at 85% efficiency and go no lower than that in normal operation. It will be very interesting indeed to get this unit on the load tester to see what happens there. Meantime, we're going to wade through the waters of the usual box and product shots first.

Entry Level Power Supply Roundup
Not everyone needs 1200 honking watts of power sitting in their new computer build. Not much has changed there. But what has changed is the enthusiast brands of power supplies that will now occupy the entry level PSU space. We have a few PSUs for you today that will not break the bank.
http://enthusiast.hardocp.com/articl...hlbnRodXNpYXN0

BFG LS-450 Power Supply
Looking for BFGTech's new quality power supplies in a power rating for a system that is a bit more reserved. We look at the smallest BFG PSU that comes in at 450 watts. And of course we put it to the same testing we put the kilowatt units to.
http://enthusiast.hardocp.com/articl...50aHVzaWFzdA==

Nexus Value 430 PSU: Affordable Silence
It's a sign of the times that a 430W power supply seems an anomaly. Retail PSU power ratings have gone through the roof over the last couple of years that even at SPCR, most of the models reviewed recently have been well over 500W. While there's some merit to the idea that extreme gaming systems actually need a kilowatt of electricity, the stronger driving force behind the power buildup is profit. There's simply more money to be made in higher rated PSUs.

The Nexus Value 430 power supply isn't just a lower power model. It's also smaller, modest looking rather than flashy, and priced well under $100. It strikes one as a return to sanity and normality before SLI and Crossfire multiple graphics cards gaming came along.

Nexus is a pioneer in quiet computing components based in the Netherlands. The company has been active in bringing quiet computing components and products to the market long before the concept became a fashionable buzzword. The Nexus brand fans, for example, are still among the few reference fans we use in our reviews.
