Enhance FLEX-0130B

As indicated by its model name, the Enhance FLEX-0130B is designed in the FlexATX form-factor. This product is 150 rather than 190.5 mm long but otherwise meets the FlexATX requirements perfectly.

The photo shows this PSU next to a Seasonic M1U. You can see they are identical in height and width but the Enhance FLEX-0130B is 4 cm shorter.

Exterior Design

There are three rows of oval vents in the top panel whereas the Seasonic M1U units are longer but only have two rows of vents there.

There’s nothing extraordinary at the back: a mains connector and a 40mm fan behind an intricately shaped punched-out grid.

Circuit Design

We’ve noted the high component density of the Seasonic M1U units above, but the Enhance FLEX-0130B is an even more densely packed PSU.

It’s even hard to make out basic features such as whether the PSU has dedicated voltage regulation or not.

With so many chokes all around the PSU, it’s hard to tell which are responsible for voltage regulation and which for A-PFC, for example.

There are three chokes in the photo above (one is sleeved and oriented horizontally) in the output circuitry area but we can’t be sure if all of them are used to regulate voltages or the third choke belongs to some other circuit.

Getting a little ahead of our review, we can tell you that the cross-load tests are indicative of joint regulation of the +5V and +12V voltages.

The mains connector is screened in a simpler way than in the Seasonic PSUs. There is no copper sheet covering it.

There are Su’scon capacitors at the output. Don't be confused by the coloring which makes them similar to United Chemi-Con components.

Cables and Connectors

The Enhance FLEX-0130B is equipped with the following cables and connectors:

  • One mainboard cable with a 20+4-pin connector (30 cm)
  • One CPU cable with a 4-pin connector (32 cm)
  • One cable with two PATA power connectors and a floppy-drive plug (31+15+15 cm)
  • One cable with one SATA and one PATA power connector (31+15 cm)

The selection of cables isn’t good for a modern PSU since there is only one SATA power connector here. You won’t be able to power a configuration with one HDD and one optical drive without adapters. The cables are long enough for compact computer cases, though.
