Seasonic FOCUS Plus 750 Gold PSU Review

[Guest]

Seasonic's Prime PSUs are its flagships. However, the PSUs that most users will buy belong to the more affordable FOCUS family. The FOCUS Plus 750 Gold is the second highest-capacity model, and it sports a strong value proposition.

Thank you for the detailed review.
In the transient response test
Advanced Transient Response at 50 Percent – 200ms
the +3.3 pass.

As always, here are the most detailed reviews on the PSU.
Thank you and keep it up!

The only thing that is not quite clear to me. What is the criterion for voltage drop in % to get PASS/FAIL in "Advanced Transient Response Tests"?

You declare that:

"In all tests, we measure the voltage drops." The voltages should remain within the ATX specification's regulation limits. "

For ATX 2.2 we have:

12v - 10%
5v - 5%
3.3v - 5%
5VSB - 5%


However, looking at your reviews, there are often situations where, at <5%, the power supply gets the FAIL mark and vice versa, some at >5% receive PASS

Why is this happening?

 

[BugariaM]

Sorry, a typo
Of course for 12v - 5%

 

[Aris_Mp]

the limit is 5% however the voltage rails of the PSUs' under test in the majority of cases aren't at the nominal voltages, but higher, so even with 5% deviation voltages go don't bellow the limits that the ATX spec sets (11.4V, 4.75V, 3.14V). Only if a rail goes below those voltage levels it fails. The 5% is just an indication that the ATX provides to specify the voltages above.

 

[BugariaM]

Now everything became clear to me.
Thank you.
