Based on the usual model PSU Flex Seasonic SS-250SU

Made for our mini FLEX mini 3.99L case.

The wires are replaced by shorter braids. Added a connector of VGA 8pin and SATA power. The case was repainted. Also we replaced the fan by a quieter from the Noctua NF-A4x10 flx



Result of painstaking work.

Have you tested this PSU under load with the fan? I checked the specifications in the past, and the Noctua has way lower airflow than the PSUs stock fan.

It does look great however!

I wouldn't replace the fan with the Noctua 40mm, I've used both in my EVGA Hadron's PSU and this noiseblocker is quieter and moves more air.

Props to you @sergiiua! Having just sleeved my modular Flex-ATX with paracord, I know how much of a pain it can be. PET is a little easier to work with, but at the end of the day, what you achieved here is incredible, and has just set the new standard for what a sleeved Flex-ATX should look like!

As many of you remember, we did modding PSU from #Seasonic SS-250SU. However, as it turned out, wire braiding is not the best solution for a mini enclosure. Install this PSU in the FLEX 3.99L body was impossible due to the hard and massive wires in the braid. Replacing them with softer white wires with a cross section of 18AWG solved the installation problem

Nice mod @sergiiua! I want to buy this PSU and only mod the fan to make it less noisy. Could you answer two questions?

1. Since you opened the PSU, would you say it looks like high-quality from the inside?
2. Does the fan have a 3-pin connector? Is it easy to replace it?

Thank you,

This looks great, wow. Nice job! One question: it looks like you split your various wires out from fewer wires inside the PSU, with the splits being crimped together. Is this correct? If so, are the innermost wires solid core or regular stranded wire? And how many wires can you get from one source wire using this technique? And what kind of amperage can a setup like this sustain?
