Seasonic Updates its PSU Product Lines

[R-T-B]

Do keep in mind that a lot of those regulate tighter and hit higher efficiency by allowing the remote end to do 30-50mV ripple, and smooth that at the remote end using in-cable capacitors. To me, it's just not as impressive a feat of engineering as seeing the AX1500i do <15mV on all rails at 1500W load without said in-cable caps.

The Superflowers use incable caps, prime does not. I agree though.

I'll cave on CapXon as I may be out of date, but still maintain using all japanese in a top-tier product is better than not, if only by a sliver.

Maybe so, but with 7 drives (2 are PCIe), 7 fans, custom LED lighting, a single power-hungry GPU, an overclocked 4790K, and various peripherals, my power requirements are closer to 700-750 watts (with a little headroom for capacitor ageing/future drive upgrades). Your 450 watt figure would be fine for 2 drives, locked CPU, 2 or 3 fans, and a midrange GPU - but I wouldn't call such a system "high end".

I can't think of any single GPU graphics card which would need a 700/750W PSU with your other components. Because if you had for example a Titan X Pascal and only overclocked the CPU you would be fine with a high-end 450W PSU. The BitFenix Whisper M 450W would be the perfect power supply for your PC.

I don't know about others but I like to buy approximately twice what I need at peak so I run the PSU at 50% most of the time. The efficiency curve tends to be higher there.

That said, it's still rather silly because the PC is seldom at peak.

My current PSU is overkill no matter how you cut it. I bought it because I wanted to reward good engineering at the time.

His test setup and rating criteria haven't changed since 2014, so his reviews and scores are just as relevant as anything he publishes now

Aris his reviews posted on Tomshardware are with an input voltage of 115V.

So either he is using different methods or he has changed his way of doing reviews. This was his response to the very similar issue of 240vs120v

actually I use a Chroma AC source so I can test at 115VAC too, but this would mean double time for all the tests I conduct and the day has only 24h

[B]@crmaris[/B] Are you using different testing voltages at different sites for the reviews?

Mostly it only affects the efficiency curve a tiny bit (higher voltage achieving higher efficiencies

Well we are talking about a few percent meaning the difference between a Good PSU and a Great PSU where millivolts, microseconds, ect all play into what most consumers would read into the testing results.
Even from this snip from a PSU review, it would play into what the reader perceives from that group of data. A few percent look's worse..................

And this from an HP server's audit

You have to constantly forge ahead to remain the best. Seasonic hasn't done much forging ahead until now.

In other words, no matter how far ahead you go. If you stop like the hare did, the tortoise will pass you by and win.

I'm really glad that Seasonic didn't "forge ahead" into RGB fans and software control like other companies - all unnecessary crap that adds to the cost or subtracts from the quality of other components. Quality/stability of the power is what matters, and longevity of the hardware.

They were falling behing in all specs against competition until this latest refresh, including electrical performance. The latest prime series is quite good however.

Most PSU nerds and engineers/designers with enough background are firmly on the "All-Japanese is all about marketing" side of the fence.

So either he is using different methods or he has changed his way of doing reviews. This was his response to the very similar issue of 240vs120v

[B]@crmaris[/B] Are you using different testing voltages at different sites for the reviews?

Looking at the latest TPU PSU review (dated 1 Dec 2016), he's keeping 230V for TPU. Most likely Tom's insisted on 110V, and with his presumably better financial situation, was able to get a 230V to 120V transformer for use there. Even then though, the performance is within the bounds of experimental results between the two voltages, aside from the efficiency, where 230V is slightly more efficient.

Well we are talking about a few percent meaning the difference between a Good PSU and a Great PSU where millivolts, microseconds, ect all play into what most consumers would read into the testing results.

<snipsnip>

Those all look a lot less impressive when you start from 0%.

Additionally, the efficiency advantage of a higher input voltage is also taken into consideration by 80Plus and the 230V requires 2-5% higher efficiency:

As long as the PSU meets the appropriate 80Plus performance levels it claims to achieve, I don't see any issue with testing at different voltages.

Table gloriously stolen from the Wikipedia page on 80Plus.

That's exactly the way I think about PSU selection. Yes, it's rather silly, but you and I will never be short on wattage, and our power supplies will never have to work very hard and should last a long time. So, even though my V1000 will probably last 5 more years, I want what you have (Prime 750 titanium), because it's awesome!

Absolutely true. That one area they are not falling behind in is the amount of nearly religious customers.

Im an ateist; so you can bring up that religion all you want to try to avoid using real arguments; Can you name ONE company that makes better PSU's for privat computers on average? (dont go into industry server hardware)Most of the other companies get their highend PSUs from Seasonic. (rebranded) Thats how good they are.

Seasonic wins or performs to A+ in all the metrics people should look at ripple suppression, inrushcurrent, effectivity, life-expectancy and so on. Seasonic may not color and RGB lighting and "G4M3Rs-CHO1CE XXXTREEMMME" tags on their PSU's but they perform. Im sure there is a Seasonic PSU that you can find that have performed unsatisfying at some point but if we generelize Seasonic is the top of the pop when it comes to PSU's and their PRIME series proves that they are verymuch in the game. People meassurering PSU on color and amount of RGB should be made fun of!

No need to get triggered.
Have a look at the PSU market below top-end products and see several competitors such as Super Flower, Evga, Corsair and now Bitfenix beating them in not just functionality but value and warranty terms. They might be good on average but the selection of products is currently also very limited and globally so-so competitive in that price range your average customer purchases a PSU from.

Noones triggered; im just sorting the trash in the forums.

EVGA = Seasonic rebranded
Super Flower = not seasonic, but close or on pair IN SOME cases
Corsair = Seasonic rebranded
Bitfenix = not even close.

How is it that they are BEATING them? can you present your "beating" metrics so we can see what the hell you mean. RGB lighting is NOT a quality when it comes to PSUs. I dont know WHAT is its that the do better performance wise? you can go read tests on the subject. Sure you can find good products from them (in corsairs case most of them is rebranded seasonic), but bitfenix does not even come close as a manufacture in general. And who is suddently talking about price!? Seasonic is a entusiast priced manufacture (thats why most of the others uses seasonic rebranded to HAVE a toptier product (their other fabs are not as good as seasonic + patents) What you are basically saying is that fiat beats ferrari due to the price. (and that is stupid) Why do you think that there is fewer!?! because of the entusiast level quality (yes it is harder and more expensive to produce.) And why would the overproduce!? that does not make any sense!? Im going to accept that you are either a troll or person that know nothing about what he is talking about.

Alright when you get this trash and your emotional arguments sorted out, PM me or something. Let's not spread any more trash here.

I am not 100% sure about this "new" lineup (yes this thread is old)
example the "new" Focus + 650w when comparing the raw details vs
the old G-650
the "old" by specs is a fair amount better (in my opinion)

new 650 full or semi modular (FX or RM respectively..so direct comparison would be the SSR-650FM, whereas the full modular is SSR-650FX
Input Current 9 - 4.5 A
Output +3.3V@20A, +5V@20A, +12V@54A, -12V@0.3A, +5VSB@3A
MTBF 100,000 hours MTBF @ 25 C, excl. fan
Approvals cTUVus, TUV, CB, CCC, BSMI, EAC, RCM

Dimensions 5.91" x 5.51" x 3.39"
Weight 6.20 lbs.

Connectors
1 x Main Power (24/20 pins) - attached
1 x CPU (8/4 pins) - attached
2 x PCIe (8/6 pins) - modular
6 x SATA - modular
3 x Peripheral - modular
1 x Floppy - modular


old
semi modular
Input Current 8.5 - 4A
Output +3.3V@25A, +5V@25A, +12V@54A, -12V@0.5A, +5VSB@3A

1 x 20+4pin Main Connector
1 x 8/4pin CPU
4 x 6+2pin PCI-E
5 x Peripheral
8 x SATA
2 x Floppy

it "seems" the old version had that much more oomph it possibly could give, seems to have more approvals, more raw feature present OCC, pop protection etc, and certainly more connectors available on it without having
to spend an extra $20 or so for the next step up which is the 750w as far as raw power, but, still gives up on extra connectors, they seem to want moe $ for it as well, go figure.
Good they have 7 year warranty, not so good in the way to get all the same connectors etc you actually have to pay more for the 750w full modular version...I know not everyone is using multiple graphics cards etc, but, is always better to have too many not being used than not enough to use if you decide to go multi gpu or your connectors for whatever reason burn out/break.

I just find it odd tbh, the "old" G650 I can get for $110, the "new" is $110 for the "plain" focus (focus + 650 is an extra $10) so same price, but loss of connectors, longer in length but shorter in width and height and a bit less weight (I think, it might be a typo in at least 2 of those numbers from a place selling them, probably the length or height?) the full modular version is almost identical but a bit heavier still.

anyways, very odd IMHO, give less, want a bit more money ^.^
