Even though there are plenty of >1kW consumer power supply units available today, it is well known that these represent a very small portion of the actual market, as the power requirements of a typical home or office PC are far lower than that. After reviewing several top-tier products, such as the efficient Seasonic Platinum 1200XP3 and the ruthless Corsair AX1500i, today we will have a look at something a lot more sensible and appealing to the average user. In this review we examine the newest PSU series from Antec, the EDGE.

Antec is a company that has always been focused on efficient and practical products rather than developing numerous high output units. They do have one 1.3kW high performance PSU available but that's about it; the bulk of their PSU products exist in the 550W to 750W power range. This is the exact range of the newest EDGE series as well, which consists of three units starting at 550W and going up to 750W. We're looking at the least powerful model today, which still has ample power for the vast majority of home users and casual gamers.

Power Specifications ( Rated @ 50 °C )
AC INPUT 100 - 240 VAC, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 20A 20A 45A 2.5A 0.3A
100W 540W 12.5W 3.6W

Packaging and Bundle

We received the Antec EDGE 550W in a colorful cardboard box that clearly specifies the focus of the PSU: silence. The box is large and strong enough to adequately protect the unit during transport. For those that are shelf-browsing, the most important features are printed on the front and sides of the box, while details can be found on the rear side.

Antec kept the bundle relatively simple. Inside the box is an AC power cable, four mounting screws, a small leaflet with basic information about the unit, a very simple pouch, and anti-vibration dampers. It is noteworthy that Antec supplies two sets of dampers, one red and one black, allowing the user to select between an aggressive or subtle appearance.

The EDGE series is fully modular and the cables are all supplied in a nylon bag. Only the few pictured cables accompany the 550W model, effectively limiting the user to just one GPU as there are only two 6+2 PCI Express connectors available. On the other hand, there are eight SATA connectors, which is quite a lot for a 550W model. With the exception of the ATX 24 pin connector cable, all of the cables are black, flat, ribbon-like cables. The 24-pin cable also makes use of all-black wires but they are covered with a normal black sleeving instead.

    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.
