Puchase date idea? Can't seem that find it online yet except on your review haha!

TBH I am not 100% sure yet. With the madness of CES I have not got the press release that has all of the release info.

We should have the information soon. Once we do I will update the review with that info and post here.

It should be released relatively soon.

Being a power supply geek I really do dig this. It's immensely impressive. I just hope it has the reliability of the AX, not the AXi.

Love the colour change idea too.

I'm wondering though... If 850W is more than enough for most high end systems, why do some people go for 1000W, just to have that headroom and some even for so that the fan doesn't spin up as soon as the 850W would. Or is this just total BS?...

The fan spinning up will have more to do with the rating of the PSU and how efficient it is. Remember, wasted power is heat, so the less you waste the cooler it runs.

850w is more than enough for any single GPU rig. Anywhere, ever.

I am running a 1500w Platinum rated, but only because at the price it cost (£75) there wasn't much around. However, I am running a buttload of electronics, pumps and fans but still 850 would probably have been enough. I will say that under full load it probably does chow down on some wattage though, being a 14/28 CPU and Titan XP.

1000w+ are meant for dual GPU set ups. Which as the years roll on become more and more rare. I saw a thing the other day (can't remember which site) and it said that based on the latest Steam survey that only 100-300k people were running SLi now worldwide. That's nothing tbh, that wouldn't even touch 1% of 1%.

850W can be more than enough for most high end systems while still being no enough for all high end systems, workstation chips like Threadripper WX & a couple of Vegas or Titans could easily need more than 1000W under load even without watercooling pumps & cooling fans and all that, it's just not many people need that setup either.

But yeah, for a gaming rig specifically you'll rarely find a system that needs more than this.

So is this a Seasonic rebrand? Wonder what the OEM is.
