Great PSU! Thx for review! "Second best" after Seasonic Platinum-1000.

I cannot agree this PSU is worth to get 'Editor's Choice'


We need to note that benchmark data does not reveal all aspects of PSU.
No such PSU Benchmark data can reveal everything about PSU Lifespan.
Because it is pratically impossible to do the Lifespan test.
How can a benchmark test site can perform 1 test for 5~10 years?

There is no way to test those stuff, and
A manufacturer very unlikely reveal their RMA statistics.

So we need to take a guess.

Which PSU will function FINE for a long time?
Not killing other components such as PSU itself, mobo, HDD, RAM,
whatever inside of your case.

Well. a benchmark is one of good ways to find it, but
internal component is also a good way.



If we compare with Seasonic X-1250, XFX Pro Series 1250 look like very identical.

I just Websurfed for 15 minutes, and found out this is inferior than X-1250.



I just visually compared the photo of Techpowerup,
and I find out XFX Pro Series 1250 took out
1 Ferrite Coil, 1 Big capacitor from Seasonic X-1250.
If component is different, then it may be different story, but in my eye, they looks identical.
Like, 420V, 390 microF capacitor with damn same label.



and Fan change from Sanyo-Denki San Ace to Protechnic.
And, I found some minor difference.


Since other Platinum, or new 1050W power from Seasonic got outstanding benchmark result from many sites, I expect 1250 will get similar outstanding result.



Another problem is, Seasonic X-1250 costs $269.99 at Newegg.com

SeaSonic X-1250 1250W ATX12V / EPS12V SLI Ready 8...

Which costs same as XFX Pro 1250W in Newegg.

If there are same cost 2 PSUs with both outstanding benchmark result,
identical manufacturer and identical internal design, but 1 has inferior component,
then which PSU deserve Editor's Choice?

[crmaris]

The components that you state exist in the XFX, I just desoldered them to provide a better view to the bridge rectifier and the resonant controller. I write this in the first paragraph of the relevant page (To provide you a better view we removed a CM choke from the transient filtering stage and the middle APFC capacitor.)

Also a PSU's lifetime depends on many factors (including luck of course, the use of UPS/surge protectors etc.) but everyone knows (or should know) that a PSU that has Japan made caps and ball-bearing fan most likely will last much more than one that has Chinese caps and sleeve bearing fan. Also the Japan caps have lower degradation so they will keep their good performance for quite long.

[ELPCU]

Oh, you mean, the first few photos are also after desolderation?

Then, it's my mistake.

Forget about my comment

Although I cannot still agree with the fan change from San Ace.

[crmaris]

yeap, I shot it without these components

np

The fan has fluid dymanic bearings so it enjoys the best possible quality.

[Systemlord]

What is EPS? In comparison how loud is the fan in the SeaSonic 1050W and/or 1250W fan at full speed?

[crmaris]

EPS are the 8 pin connectors used in mainboards (one needed for most mains while server boards take two)

Haven't tested the Seasonic X 1050 as for the XFX 1250 here is a quote from the review

With 100% load we measured 56.1dBA at 0.5m distance from the PSU installed in the hotbox, which has about the same acoustics as a chassis with good airflow.
