Why you can trust Tom's Hardware
Performance Rating
The TX-1600 achieves top performance, taking the lead from the Wentai Aidan. Still, the Corsair AX1600i remains the performance king, thanks to its state-of-the-art platform with the totem-pole PFC converter and the digital controllers. Flextronics' work on the AX1600i looks nothing less but amazing, even after several years of its release!
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
Under normal operating temperatures, the average noise output is deal low for a 1600W beast. Only the Asus Rog Thor bests the TX-1600 here.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The Wentai unit is the performance king, followed by the AX1600i and the TX-1600 comes third. This is not bad, at all, given that the latter doesn't use a totem-pole PFC converter, like the aforementioned units.
Power Factor Rating
The following graphs show the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius and 115V/230V voltage input.
The APFC converter needs tuning for higher readings, especially with 230V input.

watzupken Not unexpected coming from the Seasonic Prime series. However, the lack of ATX 3.0 is going to affect its take up rate. Most people buying a 1.6K W PSU are likely enthusiasts that will want the latest and greatest. This is great, but clearly not the latest.Reply -
escksu 1600W is definitely overkill for most. For the rest of us, a good 600-800W will be sufficient.Reply -
jeremyj_83 Every single time people think that Seasonic will have to go with digital circuits to reach requirements they figure out how to do it with analog circuits. It is amazing that they are able to get the same or better performance using analog circuits compared to most other high end PSUs using digital circuits.Reply -
infopcX Thanks very much for review, amazing work !!!Reply
can we say that this is the second best source money can buy? just behind the Corsair AXi 1600 ?
power factor could be better, in practice compared to the AXi would be imperceptible? would even values below 1% in efficiency be relevant? I say in practice
I would like to know how much we could extract from the Seasonic source? up to 110% Load seemed pretty stable, could we go further with it?
12 years warranty is a plus
