Nobody said anything about a Titanium unit having good holdup time.
The "I didn't say what we can quote from the posts above" thing is becoming a recurring theme

Was it nobody who posted this on September 7, 2016 4:23:49 PM ? Tho you didn't say "good", you said "incredible" and 'high".
Also, this unit has incredible performance and also incredible holdup times for its price....Think of a place like India, how helpful a high holdup time like this may be for somebody who doesn't feel like dishing out a ton of rupees for a UPS; the holdup time along could really help the PC remain running with the unstable AC they have there.
Everything you say in that quote is nothing I said.
Everything I have said is quoted from your posts starting with your introductory statement
I totally understand the ooh and wow for Titanium units., There is a direct mathematical connection between efficiency, noise, and lifespan. Assuming hypothetical units A and B to be identical, except for B being more efficient, the increased efficiency of B results in increased lifespan or the ability to maintain the same lifespan with a slower-spinning and quieter fan on B
I still haven't seen the justification for the ooh and wow part. Like the hold up time statement that you "didn't say", there's no ambiguity in your post here on the board, It doesn't say **might** result in increased lifespan ... it doesn't say **might** allow the same lifespan with a quieter fan.
When you wrote "Assuming hypothetical units A and B to be identical".... I very clearly prefaced my responses on a very important distinction:
All things being equal, I agree.... but the fact is, things are almost never equal.
Yes, so what we have here is what we agree is true in the theoretical instance versus the reality of the marketplace. The review initiating this thread and the position I have put forth is based upon the assumption that the discussion context is units like the Seasonic Prime available in the real world marketplace. And when we limit the discussion to what one can actually buy, there is no 100% guarantee that a titanium rating brings anything to the table other than an implied cost of electricity. When you see the titanium rating, you may take (assuming the manufacturer isn't lying and it holds up in testing) that the unit will deliver the following:
at 10% load the efficiency is 90% or better
at 20% load the efficiency is 92% or better
at 50% load the efficiency is 94% or better
at 100% load the efficiency is 90% or better
That's it,
nothing more. Anything beyond that can only be characterized as possible, maybe even likely or highly probable but the assumption of it being 100% true is certainly not something that I think one should rely on for purchasing decisions, especially in this price range. Especially when there is no need to imfer an iffy conclusion from an efficiency rating when verified actual test data on the various performance criteria you believe the rating implies is readily available.
As per above .... Kenyan runners have the routine opportunity to run in atmospheric conditions which give them a significant competitive advantage in long distance running.
Paraphrasing your words ... "all things being equal", as the atmospheric conditions in Kenya produce better lung capacity and oxygen transfer efficiency in the blood, Kenyan athletes will be able to maintain peak running speeds with slower breathing and the endurance advantage **results** in Kenyans winning all the races. Again, the problem is that it doesn't say **may result** and
all things are not equal .... nutrition, training methods, use of hyperbaric chambers, sheer will, stride length, individual biology all factor in to who wins the race.
I have agreed with you from the getgo that higher efficiency is an advantage and that **all other things being equal**, this does carry over and beneficially impact other performance areas. My reservation is we don't have access to a marketplace where **all other things are equal** and since we don't, the efficiency rating is a guarantee of nothing other than relative electricity costs. These carry over benefits may be offset by other criteria.
Again I am using fans as it is a simple concept to use as an example rather than go thru every test result. But the same applies to every other performance criteria. Yes the lower efficiency / lower heat does give the unit an advantage ... but there are ways of offsetting those advantages as was evident in the CP-850 design which didn't even manage a bronze rating. The same PSU that SilentPCreview called the "quietest PSU they ever tested".
I really don't understand the relevance of the "jonnyguru doesn't test decibel level" comment. Other sites do, and ... in the context of this thread which is linked to a THG article which did in fact list and graph noise levels. Noise is an issue of concern for me.... I invest considerable sums in water cooling not for increased performance as with current CPUs / nVidia GPus, it's most often not attainable over air, I do it for decreased noise. The only fan you can hear in my son's water cooled (CPU only) w/ SLI'd air cooled 970s (w/ 9 case / rad fans) is the fan on the EVGA G2 1000. So yes, thius is something I have high on priority list so do go searching for this data when it's available.
If you are not saying that "Titanium units always have low noise and always last long"... or "always have good hold up times", great voltage stability, low ripple, and so on, then I gotta go back to the original statement.
I totally understand the ooh and wow for Titanium units, especially ones like this.
What's the ooh and wow factor of this Titanium ratings if this rating is not **always** a reliable indicator of any of those things ? If you are not saying that, then the Titanium rating
does not necessarily mean that they will:
-have low noise
-last long
-have great voltage stability
-have great hold up times
-have low ripple
-have great voltage stability
If we can't depend upon it **always** than I don't see the ooh / wow factor unless of course the cost of electricity is a major decision factor. I don't even look at the "metal" rating... tho I live in an area of high electricity costs as compared to most of NA, I would consider it if I lived in many parts of Europe. But when we go PSU shopping should we:
a) See the Titanium rating, say "ooh wow" and stop looking ..?
b) or go thru the available review / test data ignoring what high efficiency might imply if **all things were equal** and see what readily available test result are for temps and noise (at various loads), ripple, voltage stability, inrush current, hot box performance, actual efficiency (we have all seen units not manage to pass what their ratings imply). Do we ignore protection features, infrared image results, transient results, build quality (i.e. does sloppy soldering and other poor workmanship matter) ?
This is not very different from the argument that the PC component that costs more, **all things being equal**, will be better as Titanium units *usually* cost more than Gold which in turn cost more than Silver and so on. Yes it does cost more to build better quality products and perhaps more often than not, a higher cost component will outperform another comparable all other things being equal lower cost unit but this is not always true ... and yet how often do we see peeps post a proposed build where they just picked the highest cost component in each pcpartpicker category ?
What I am trying to convey is that I am not misinterpreting what you said, after all I'm quoting your posts. I agree with you 100% on the **all things being equal part**. What I am saying is the "all things being equal" premise is not relevant to a purchasing decision as all things are not equal.
If you are not saying that "Titanium units always have / provide [insert anything here other than electrical efficiencies]", then w/o the **always**, it don't see how i could rely on it as a 100% reliable indicator of anything upon which to make a purchasing decision. What the Titanium rating may imply with regard to any measure of performance is not as reliable an indicator as the actual measured performance. I'll leave you with this
My wife's Italian ancestry (both sides) implies that all things being equal she should be the better option to cook (and can) the tomato sauce every other weekend given the exposure to a large family where weekend meals were attended by lots of relatives with many recipe ideas ... but it's the dopey half English / half Irish guy she was foolish enough to marry who performs the task. Wifie can be a very good cook, but she tends to multi-task while cooking (laundry, phone whatever). If we let Mom do the pasta cooking, no one here would have ever experienced "Al dente" ... after a taste test of "too hard" she'll tackle another task and when she comes back, Al dente left the building. She has taken over canning duties tho. She has to cook all the meat tho ... which she does very well.
It would seem that we agree on what's what under each scenario ... what we don't seem to agree on is what premise is applicable to decision making. If I understand correctly the rating appeals to you because it often does mean other advantages in other performance categories, I just don't get why the "metal" rating is of significant "ooh wow'" value when the actual data on those performance categories is readily available and is a more accurate indicator of where the unit stands in that regard.
