The flagship in Antec's Signature line achieves very high performance while running very quietly at the same time. How does it compare to competing high-end offerings from Corsair and Seasonic of similar capacity? Is the Antec Signature Titanium 1000 W worth its $280 price tag?

Outstanding review. Believe the Antec Signature Titanium 1000 W aesthetic looks amazing. Some enthusiasts may prefer this very gorgeous chassis (imho) vs the Seasonic TX-1000 Prime Titanium oem platform it's built upon.

Price is about the same for both skus Antec and Seasonic, $279 vs $289 depending on where you shop.

Been using a Seasonic 850watt Prime Titanium since August 2016 and the 600watt Prime Titanium fanless since October 2017, never a single issue, amazing rock solid units for overclocking and driving high-performance 2dimm motherboards.

--------

Grabbed an Early Bird Special on the new Seasonic TX-700 fanless. For two days only, you could buy the new 700watt Titanium rated sku for only $209.99, then the price went up to standard Newegg of $259.99, ouch. :oops:

Kinda thought the 700watt fanless would debut at $249-$269 considering tarrifs fanless design premium components and everything else going on right now.

Been waiting for this unit since Computex 2019, Newegg ships them out on April 20th, something simple to look forward to during these uncertain happenstances. :cry:

Hoping crmaris can grab a TX-700 Titanium for review, although by then I'll already have one installed and up and running sweet and silent in the Batman build. :)

Go crmaris Go! :clap:

Looks like a beast of a PSU... nice!

...and holy shyte... full size images inline....wth?! A link next time or smaller pictures @E-curbi?

Your wish is my command. lol

Images reduced to thumbnails, poof - like magic. :)
 
I have a 1000W Titanium from EVGA, but let be honest, PSU with high watts are "dead".

I used commas cause there's obviously a few cases where is needed, but power consumption from AMD (CPUs) and NVIDIA are decreasing.

If you have a 10900K + SLI 2080 Ti you can't use 1000W or if you willing to go 3990X + 2080 TI you cant top out 1000W.
 
I agree for the most part... but there are always exceptions to the norm. I'm sure there are users running distributed platforms (F@H, WCG, etc) with 3 GPUs and an overclocked HEDT CPU. Or content creators with multiple high end cards and HEDT...

It is rare... but there are uses, for sure. And then there is the halo product effect too. ;)
 
High capacity PSUs are ideal if you have the money to get them because at high load scenarios they will operate at their peak efficiency (or close to that). While a PSU that merely covers your needs will be at 80% and above of its max-rated-capacity where efficiency deteriorates. Moreover, with the burst mode operation at light loads, efficiency is high even from a 2% load and upwards. The statement that high capacity PSUs are not so efficient at light loads doesn't apply anymore. All the new designs are surer efficient in any load range. Moreover, they will provide longer hold-up times at the same loads with a lower capacity unit and they will be stressed less, in general. Please do note that all above do not apply to all high-capacity PSUs, and this is why you need to read reviews and get informed before you buy one.

Oh.... that 1-3% will really start hurting your electric bill. Those pennies add up over the year (sarcasm).

Unless you are running under load 24/7, buying a 1KW psu versus say an 750W psu (same 80 plus rating same brand/line) the costs will likely never be made up if you load it at 80% as opposed to 50%.

That said, 80% is the highest I would go and prefer to be around 2/3 to 75%. This allows for quiet operation, ample headroom, and room to upgrade while not wasting cash on something overkill.
 
Not going to drop into the argument for or against 1000watt PSUs, but I do know Newegg and Amazon in the US sold out of the Seasonic TX-1000 Prime Titanium two weeks before last Christmas, and Newegg only restocked last week, and SOLD OUT again in only a few days - most buyers waiting 3months most likely on the notify list.

Maybe having a full Kilowatt simply makes some people feel better - come what may.

Maybe they aren't super-enthusiasts and just want to play it safe - plan for the future OR the obverse - maybe they have a digital load meter on their desk (like me:oops:) and are extremely aware of their need for a full 1000watts?

Whatever the case, 1000watt Titanium units certainly seem very popular, despite the price tag.

Calculated my average watts used "80% of the time" while working and seems to be 18% of the 600watt fanless sku or 15% of the 700watt fanless sku. Efficiency difference or delta at both those values is simply negligible. Yet, I still feel more comfortable with the 700watt unit. Why? Silly human nature I guess. :ohwell:

Maybe it does make people feel better... but it doesn't make sense fiscally, for most.

As far as 1KW Titanium units being 'popular'...not sure I buy that. They are hella expensive... and that excludes most users from getting them in the first place. People can't/don't want to afford a $250 GPU, nonetheless a $250-$350 PSU. As was said above, you can make a case for getting one, but you are in the realm of multiple high-end GPUs and HEDT CPUs, all overclocked.

If they buy because it because they are most efficient at 50%, they have lost/didn't have sight of the big picture and how they will likely never come close to making up the cost difference. A little bit of math goes a long way....

I'd be willing to be 95%+ could run a 750W PSU without worry. I'm on the high end with my setup (7960x overclocked and 2080Ti), and don't even pull 500W (~450W is right). I can add another 2080Ti in there and be ok. In fact, I've actually done this before, lol.... I pulled around 675W with everything overclocked. I'd run that on this PSU for the the parts' useful life.

Didn't Antec use to make their own PSUs?
Great review as always.
 
Sorry about that yea, I was meaning 1000watt units seem very popular among the titanium units - despite the higher price.

I have to apologize, my thoughts are mostly abbreviated when it comes to PSUs, only really follow the titanium models.

I don't follow the PC parts market as a whole any longer, did that in the beginning not knowing which way to go, but once you find out what works best for your work apps or work environment, I wouldn't know the latest craze in Gold or Platinum, what's hot what's not - who has time to remain a highly ranked contestant on PC Jeopardy anymore? Not me... :laugh:

Not that there's anything wrong with that, do what you LOVE. :)

But I do like to follow my niche parts - new efficiency and speed parts always turn me on. :clap:

Speaking of which, cannot wait to swap out this Seasonic 850watt titanium sku (photo below) and return to fanless once again. The self-test on the fan at start-up and wake from sleep, is so noisy in an otherwise noise-free office environment, also slows down boot time, two of the benefits of going fanless that no one ever tells you about - yep I'm beyond weird (raises hand). :)

My first love is brought to live. :love:
I'm still using my Signature 650. 10 years and powered my Athlon X2 then Wolfdale then Sandy Bridge and now my Matisse.
Never saw such a PSU. :eek:

Hope that revamped Signature will continue the legacy.

Thank you crmaris for your review and bringing me back some memories.:toast:

Yeah. But that was a long time ago. I think they are barely just clinging on to relievence

I just bought a Seasonic 1000W "PX-1000" Platinum from newegg a few weeks ago for a 9900k+Vega64 system, and that's to eventually replace my aging 2013 purchased Platinum 1000 for a new upcoming build as well. And frankly I get very very upset and irate when someone says "you wasted your money" or something. No one has a right to tell someone how to spend their money.

Does, 'spent more than one had to' sound better? :D

I really wanted the 1000w Seasonic Ultra Prime Titanium...... I settled for the 850w variant at the time it was $75 cheaper considering I can only get my 9900K/2080 ti to 600W running super unrealistic benchmarks at the same time I probably made the right choice...... I almost settled for the 750w variant for my 3900X/Titan Xp system but couldn't bring myself to do it considering I was saving like $15-20 over going with another 850w variant.

I really like that Antec ditched the caps had Corsair done the same I would have grabbed the AX850 for my Ryzen system.... Glad to see all 3 AIB doing really well with variations of a Seasonic Titanium PSU.

Thanks a lot for the review.
What do you think about Super Flower Titanium series?

They were always outsourced from oems like fsp, cwt, Delta, seasonic among others.

No one is telling you what to do with your money, but sometimes isn't the smart choice =)

Like i said i also have a 1000W titanium, but i bought very very cheap with 10 years warranty.

I paid $170.

This comment aged like milk. A 3090 Strix OC with its stock 480W Bios (power slider maxed in Afterburner) and transient spikes to ~600W + 10900k @ 5.3Ghz triggers OCP protection on Seasonic Prime TX 850 which is basically one step lower than the 1000W PSU reviewed here.
 
So, my Antec Signature Titanium 1000W died today after just 2 months of very light use. Running a 3090 Founders Edition with no overclocking. I started getting random restarts yesterday while working in a 3D painting application which I thought was very weird as the GPU was nowhere near full load and temperature around mid 30's Celsius.

Updated the GPU drivers today and was working away for two hours when I got another random restart. This time though the PSU gave up the ghost.

Just unlucky or is there a known issue with this PSU and the 3090 cards?

That sucks, I have not seen anything online with seasonic builds and the new RTX series (doesn't necessarily mean there isn't one). Luckily you are clearly within warranty so you can contact Antec asap for a replacement. I will say I've owned more seasonic builds than any other oem but I've also had more issues with them (mostly coil whine related).
