Antec Unveils 750W EDGE Silence Defined PSU

[btarunr]

Antec expanded its super-quiet EDGE Silence Defined line of power supplies, which made its debut in September with 550W and 650W model, with a series-topping 750W one, aimed with gaming PC builds with up to two high-end graphics cards. The unit is characterized by a 135 mm FDB fan that stays off until the unit kicks a load/temperature threshold; and rubber grommets and bands that dampen whatever little vibration slips out of the fan.

The innards of the 750W EDGE Silence Defined are made by Seasonic, featuring a single +12V rail design, APFC, Haswell C7 state support, and all modern electrical protection mechanisms. The unit features fully modular cabling, with enough juice and straws to go around, for a build with two high-end graphics cards.

Sounds like a nice PSU!

I have CM Silent Pro it came with silicon strips. I've never used them. It's silent as is. But it's a nice touch, to have them just in case.

Marketing ftw. I don't get how much more silent they could make them. My Antec 750 is already pretty quiet.

Unless this PSU tests as good as an equivalent genuine Seasonic and costs less, what's the point, just buy the genuine Seasonic instead of a badge. Many of the newer Seasonic PSU models do not run the fan at all unless it's necessary as the load increases, so it's pretty much impossible for a PSU to be more quiet than another one with no fan running.

First thing I thought of when I saw this post:

'It has a 135mm fan...must be a not-Seasonic Seasonic'.

The thing is, most of those are ~850-1050w based on this platform, right? Perhaps there are others (I have not followed it closely), but this could help carve a market if it's essentially the same design but with (I don't know how else to say this) cheaper components that lower the practical usage. That doesn't mean they are necessarily a bad option, and I'm glad someone is trying out this combo (lower power, zero-fan + 135mm). These could finally be a decent ~$100 psu for a lot of people that want good efficiency for a typical single high-end/dual performance gpu build.

You say 'what's the point of buying a Seasonic rebadge', but in reality many of them are quite nice (and sometimes cost less). I personally prefer the fact evga and cooler master (and probably others, those are the two I am familiar) DO NOT use the zero fan circuitry, and keep those components cool at all times. By all accounts they are all still inaudibly quiet (up to around 700w iirc for the 1kw models), and there isn't up to ~400w of generated power supply circuity heat (or whatever it is when the fan kicks in on the Seasonic branded models) being dumped into your case. The fact this Antec is rated lower means that threshold is probably lower, which is nice, but I'm still not a huge fan of no fan running at all times.

TLDR:

Seasonic-branded: No fan up until 40-50% load (or whatever it is), and then a (granted, nice) 120mm fan plugging away. Typically 170mm for 860w based on the newer platform, a lot longer for 1kw.

Seasonic rebrands: Very quiet 135mm fan up to around 70% load for 860/1kw, and then obviously quieter than a 120mm fan. Typically 170mm for both ~860w/1kw.

I don't know about you, but I was heavily considering a V1000 up until eVGA literally just launched similar models (Gold 1050w/Plat 1kw). I will have to see how those fair according to the boys at JonnyGuru, but I still think any of the above (including this Antec if you don't need more than it comfortably offers) will be a better option than an original Seasonic.
