Packaging, Contents, Exterior & Cabling
The box's design looks nice, with gold accents stealing the show. On one of the two sides, we find technical and power specification tables. The back covers the SSR-750FX's most important features, including its efficiency rating, the DC-DC converters, the single +12V output, high-quality filtering capacitors, the 120mm FDB fan, Seasonic's semi-passive mode, fully modular cabling, and a 10-year warranty.
Tight load regulation is also mentioned as one of this PSU's strengths; according to Seasonic, it's within 3% on all rails. In reality, that's not particularly tight by today's standards. We think you need to be close to 1% (or lower) for such a claim.
Protection inside the box is adequate; two packing foam pieces totally surround the PSU. On top of the PSU, you'll find a piece of paper describing a giveaway for customers who share their personal experience on Amazon and Newegg. This contest is only for U.S. residents, though.
The PSU is stored inside of a cloth bag. It's definitely a nice touch, given that most PSUs in this price range arrive in plain plastic bags.
The bundle includes a user's manual, a set of Velcro straps, several zip ties, four fixing bolts, a case badge, and a pouch that can be used to store unused modular cables.
An AC power cord is also provided.
Up front, we find the AC receptacle, the power switch, and a push button that toggles the semi-passive mode on and off. Two decals on the sides show Seasonic's logo and the line's name. A power specifications table is easy to reference on the bottom.
The fully modular panel includes 11 sockets.
The SSR-750FX's design isn't particularly innovative, but its finish looks nice. Light-gray stripes around the screws up top, along with a gold Seasonic badge on the fan, are nice details.
Unfortunately, Seasonic adds extra ripple-filtering capacitors to the ATX, EPS, and PCIe cables, so they're quite bulky. You'll have a harder time routing them around inside of your case as a result. The peripheral cables, which lack those extra caps, are flat, so they won't inhibit airflow inside of your chassis as much.

In the transient response test
Advanced Transient Response at 50 Percent – 200ms
the +3.3 pass.
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?
Of course for 12v - 5%
I would greatly appreciate if someone could help me out. Thank you kindly in advance:
