I did some research and the Seasonic Focus GX is a new product and replaces Seasonic FOCUS PLUS Series.


Seasonic Focus GX LINK: https://seasonic.com/focus-gx

"Seasonic’s engineers have implemented a new design feature, where instead of cables; the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality."

"In 2019, Seasonic engineers have made improvements on the popular series, removing the inline capacitors on the supplied cables. Besides the small change in the series naming, the PSU housing and its packaging are also updated to be in line with the concept of the OneSeasonic Initiative."

"This breakthrough solution"
heh, as if busbars weren't a thing.

on a side note, SS-GX/SGX still has the issue of 3.3v going out of spec in heavy transient loads.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

Please provide some info to back up your clams.

You can check negligible differences in voltage delivery between Gold and Platinum units in jonnygurus reviews. The difference he gets between gold and platinum units are laughable and the latter costs money. PC user also never loads his PSU to let it be close to reach 100% either. 3 percentage points difference between Gold and Platinum in a 750W unit is literally nothing. Economically, it's like this, calculations done for 'muricans:


Daily PC use: 10 hours
Average power consumption by PC components: 75% of 750W (let's say it's a strong PC) = 564W
Electricity cost: 0.1895 USD/kWh
Yearly usage, so 365 days


Gold unit (Corsair RMx):
Efficiency at 75%: 89.3%
Power inlet draw: 632W
Cost: 150USD
10*365*632*0.1895/1000=437 USD





Platinum unit (Corsair HX750):
Efficiency at 75%: 91%
Power inlet draw: 620W
Cost: 175USD

10*365*620*0.1895/1000=428 USD



Through a year you saved 9 USD, you need three years to make it pay for itself at constant typical load, you could spend that 25 dollars on a beefier motherboard, in example. Unless it's a difference of a quite a sum of devices - it's a wasted cash. Of course, as a society we should go for highest energy savings as possible and it's good that power supplies grow more efficient. Economically, it has little sense for a single household unless it goes for efficient devices from the very start. Now, PSU life expactancy highly depends on overall build quality and used electronic parts, and there's honestly barely any difference between ~750W top Gold units. Ripple has been brought to a level that no longer means anything. I'm avoiding the fact that very strong (1kW+) units are pretty much Platinium and Titaniums only on purpose, because their rating usually just goes along the way with power supply capability (well, higher quality PC PSUs at least do so)

Ok thanks for posting, makes sense. Ripple has my interest atm as im in the market for psu. From what I gather like you mentioned most quality units provide smooth power delivery. As long as it's in spec, filter caps on mb/cards take care of rest.
