Antec is marketing the EDGE series as "the pinnacle of power supplies". While that may not be very accurate, as there are several significantly more advanced products available, this is a 550W PSU with a "Silence Defined" marketing label. The intended purpose of the EDGE series is to provide low noise, high quality units to mainstream users, not to compete for the crown of the highest possible performance or technological superiority. If you are looking to power a behemoth with multiple GPUs or a cryptocurrency mining machine, none of the units of the EDGE series are suitable; for "normal" users, however, 550W-750W is more than sufficient.

In terms of quality, the Antec EDGE 550W is excellent, both externally and internally. It is hard to fail a quality check with Seasonic as your OEM, but the EDGE 550W unit that we reviewed today is perhaps the most well made <700W unit that we have seen to this date. Inside are some of the best components that can be used for a consumer-grade PSU, while the assembly/soldering job is immaculate. It is no surprise that Antec covers the units of the EDGE series with a 5-year warranty.

Antec also puts in a commendable effort to make the EDGE series aesthetically appealing. The modular cables, perforated chassis, stickers, and white LED lighting form an overall look that does stand out, yet not overly so. For those that dislike the white lighting or lighting in general, the installation of an on/off switch is a thoughtful choice.

The primary sales point of the Antec EDGE series is "Silence" and the 550W unit passed all tests with flying colors. Its high efficiency and low capacity account for very low thermal losses. Aside from a completely fanless unit, such as the 520W Nightjar, the Antec EDGE most likely is the next best thing that money can buy. It also has great electrical performance, with very good voltage regulation and line filtering characteristics. The high ripple of the 5V line is unusual but it is still well below the ATX design limit, therefore we cannot really voice any complaints about it.

The Antec EDGE series is very interesting but, due to the narrow wattage range, it only appeals to those with more moderate needs. These units are designed for the casual home/office user and the average gamer, the type of user that will install only one good CPU and GPU, a couple of drives, and work or casually play games. The EDGE also takes things a step further and targets silence/quiet operation.

This category, the "mainstream users", is undoubtedly the largest portion of the market, but due to their high price the Antec EDGE units will be interesting to just a small fragment of it. Even the 550W model that we reviewed here today, the least powerful unit of the EDGE series, has an MSRP of $120, a price that can easily get you an 80 Plus Gold PSU that's twice as powerful or even two Corsair CX600M units (for $10 extra). If the actual retail price of the EDGE units isn't significantly below MSRP when the series hits store shelves, the EDGE will have a difficult time competing in today's market. They may be quieter than much of the competition, but the price premium still looks very steep.

    This seems like a pretty good psu. Should be enough for an i7 5820k and single gtx 980, with plenty of room left for overclocking.

    The very first thing I look for in power supply reviews is which company is the manufacturer. Some you trust, some your iffy about and others you simply try to avoid. It's sometimes very hard to get that information and companies tend to jump from one manufacturer to the next in the middle of a products life cycle which makes it even harder.

    I am very pleased to see Antec (and Cooler Master come to think of it..) partnering up with Seasonic. It means I will be buying a lot more of their Power Supplies. I am also pleased to see Antect paying more attention to their cabling. It's always been a bone of contention for me and fully sleeved cables with no multi colored wires is always a plus.

    Since I am pretty confident that someone at Antec will read this.. You dropped the ball on a lot of your casing designs of late. The Sonata needs a overhaul and the Lanboy should be a top seller if it's based on it's old Super Lan boy Aluminum design with slight modifications to factor in new cooling and cable management. ( a Removable MB Tray would be nice for enthusiasts to..) It's really not rocket science to figure out.

    Take the Sonata redesign Throw in a power supply like this one and you got a win/win. The Sonata was billed as quiet but yeah.. no it wasn't still it's a popular casing that does need a minor refresh as well..

    Anyway E. Great review.

    I've got a Solo II (part of their Sonata lineup) that's pretty quiet, and has excellent build quality. The HDD suspension system is nice too, as is the SSD mount location. It's probably one of the shortest cases that supports full ATX boards and large graphics cards without major flaws or an insane price tag. With that being said I do feel they could improve on it a bit. But for its size they did quite well.

    So I can get a Seasonic G550 for about $40 less than this Antec/Seasonic PSU. I also get the same 5 year warranty on the unit and it's Gold plus certified. How do Antec expect to sell their branded Seasonic PSU?
  • Daniel Egger - Friday, October 3, 2014 - link

    It's good to see the reviews finally moving from insanely crazy to regular overkill but 550W is still way out of range of what an average user needs and that's even including a heavy duty graphics card, for those 350W are more than plenty. For "average" by that definition I'd like to see a review of a Seasonic X-400FL Platinum or a similarly good performer. The only point I can see in going for overkill is the better optimum efficiency at medium loads and quite frankly the Antec is simply not that good at this rating and price point...

    Antec only makes good PSUs now and even then they can be quite expensive compared to the competition (even SeaSonic). I remember back when Antec was the brand for computer cases with their 900, 300, and sonata series. It's sad to see a once big-name company like Antec be a shadow of their former selves.

    Thanks for giving us a review on a lower-rated (less than 1kW) power supply! I really appreciate it - these are what I use when building my mini-ITX cases! Well, I also use SFX PSUs like the one Silverstone supplies.

    I would also love to see a test of some common GPUs (single, not SLI/Crossfire configs), Intel i5-i7s, and what is really needed to power such "common" systems.
  • romrunning - Friday, October 3, 2014 - link

    Also, thanks for calling out the price. $120 is a bit steep for a budget/mainstream gaming build.
  • Daniel Egger - Friday, October 3, 2014 - link

    H81/87, Core-i5/7-4xxxS, SSD and GTX 750 Ti OC, BD-ROM are (at the wall) < 30W idle and around 130W if you throw FurMark and wPrime at it; that's already after the loss of the power conversion. You do the math...

    "I would also love to see a test of some common GPUs (single, not SLI/Crossfire configs), Intel i5-i7s, and what is really needed to power such "common" systems."

    As Daniel Egger said - far less than most people think. I have an i5-3570, even OC'd to 4GHz under Prime doesn't break the 100w barrier. Idle's at 37w (with discrete GPU which falls to 26w iGPU only), and it's not even a Haswell. Throw in an efficient nVidia Maxwell based GFX card (eg, 750Ti) and run Prime + Furmark and you're still under 150w under unrealistic synthetic "double power virus" conditions. For most normal gaming, it's nearer 80-120w (for a rig that can run most games at 1080p on console equivalent "Medium" setting) and wouldn't even use 50% capacity of a Seasonic G360. For high end gaming rigs, even a new GTX 970 would remain under 300w (maybe nearer 250w if you undervolted it a little) and easily function off of a decent 500-550w PSU at 50-60% PSU capacity.

    For non gaming rigs, it's more like 40-70w just browsing the web & using office, 100w max full video encoding, etc, and that could easily run off a Pico-PSU laptop style power brick. All above figures on my rigs are measured at the wall with a kill-a-watt on Gold rated Seasonics, not merely 'calculated' from TDP, etc.
