Although I presently own a SuperFlower LeadEx based unit (The EVGA Supernova P2 850W), I can't deny I would very much like to see Seasonic do a one up routine on them. I won't need it, this is already good enough for me, but competition never hurts!



And to do such efficiency with double the hold up time certainly SOUNDS impressive... Posted on Jan 10th 2016, 22:32 Reply

I still have Seasonic-made PSU bought in 2007 powering an old PC. Who would have thought that it'd past its 5-year warranty and still going strong. Been hammering it down since the first day too. When it comes to PSU, I only trust Seasonic and Corsair (doesn't matter who the OEM is, the design and component choice itself are well-thought). Posted on Jan 10th 2016, 22:53 Reply

That's a very clean and simple layout, and a ten-year warranty is class-leading... but I bet they'll cost a ton. I'd like to know the reasoning behind the extended hold-up time, since many PSUs today can't even hit the 16ms ATX standard. Posted on Jan 11th 2016, 2:43 Reply

Heh, why do they ALWAYS have to release good stuff after I buy something like that. I like my BeQuiet Dark Power 11 Pro unit, but this one is neat. Just look at the components! It's all nice and "not crammed". It means it'll cool better and run longer. Which tells by a 10 years warranty. Posted on Jan 11th 2016, 4:12 Reply

PC Gaming Enthusiast I only wish i needed one...these look extremely good. I bet even the 650w unit goes for no less than $180. Posted on Jan 11th 2016, 6:38 Reply

Cool!

Perfect timing for my new build, but when?

I suppose that the smallest will come last? 650W? Posted on Jan 11th 2016, 7:40 Reply

I really hope that the PSUs are physically smaller, so they fit in to more compact cases while leaving cable management room. Posted on Jan 11th 2016, 8:17 Reply

Been buying SeaSonic units exclusively for the last 5 years. I guess when the Antec in my home Win2008 server quits working, one of these PRIME units will be my next purchase. Posted on Jan 11th 2016, 9:06 Reply

Finally a worth upgrade to my ancient Coolermaster Real Power M520 which is still powering my main PC. That 650W Titanium rated supply is looking really good. Posted on Jan 11th 2016, 10:53 Reply

Now Gold standard will be minimum.

I don't know why all companies made same PSU cables...

I would make all cables rounded, rubberized, same as power cord and on end nice plastic finish to cover wires and connector same as end of power cord or USB cable or similar things.

Only ends of connectors will be compatible with all hardware, everything else would be completely different.

That would be accept from market, special in hard core RIGs for people who are want fast and nice solutions and excellent cable management. Posted on Jan 12th 2016, 8:22 Reply

Resident Wat-man btarunr Ten-Year Warranty Just when I thought that the 7 year warranty on my 1000-watt Platinum was a lot. :p



I can't say I have any complaints about my Seasonic unit or ones I've bought for other people. Simply a quality brand.

But please no coil whine this time around Seasonic. Posted on Jan 12th 2016, 9:36 Reply

Coil whine on the Platinum series has been a common problem ever since it came out.



Its not a problem on all of the Platinum PSU´s but a good chunck of them have noticeable coil whine on them.



This is common knowledge so its nothing new. Posted on Jan 12th 2016, 10:08 Reply

This is common knowledge so its nothing new. This is more of an QA issue than a poor design by SeaSonic. I currently own a Platinum 660, X-750 KM3, X-400 Fanless, M12D 650 and S12-2 520. None of them produces audible coil whine.



BTW almost all PSUs have some sort of coil whine. It's just the intensity is so low and masked by the noises produced by other components inside the case that users won't notice it.



Now if you're building a fanless silent PC, then yes the coil whine could get really annoying. In thise case RMA the unit. This is more of an QA issue than a poor design by SeaSonic.

As said its not on every Platinum and some of them are worse then others.

But it would nice if this new series dont have that problem at all. Posted on Jan 12th 2016, 10:31 Reply

Resident Wat-man rtwjunkie Yeah, not really common knowledge and not something I've experienced on either Platinum I have. Thanks for the explanation, though. Same experience. If my platinum has coil whine, it's considerably quieter than the rest of my machine or any other coil whine I've heard in the past. I've heard people saying that they've had coil whine with Seasonic units but I've yet to experience that with the two gold units I bought for other people and the platinum I have myself.
