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

The photograph shows this PSU next to a
Seasonic M1U. You can see that they have the same height and width but Enhance
FLEX-0130B is 4cm shorter.
The exterior design
The
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.
A
power connector and one 40mm fan.
There's nothing special in the back: a
power connector and one 40mm fan behind an intricately shaped punched-out grid.
Circuit design
The
density of components is high
We have noted about the high component
density of the Seasonic M1U unit, but Enhance FLEX-0130B is a packaging PSU
which is more crowed.
Trouble
creating basic features
It’s even hard to make out basic features
such as whether the PSU has dedicated voltage regulation.
Many
chokes are all around the PSU
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.
We're
not sure if all of them are used to regulate the voltage or the third choke
belongs to a different circuit.
There are three chokes in the image above
(one is sleeved and oriented horizontally) in the output circuit but we are not
sure if all of them are used to regulate the voltage or the third choke belongs
to a different circuit.
Getting a little ahead of the review, we
can tell you that the cross-load tests are indicative of joint regulation of
the +5V and +12V voltages.
The
main connector is screened in a simple way
The mains connector is screened in a
simpler way than in the Seasonic PSUs. There is no copper sheet covering it.
There is Su'scon's capacitor at the output.
Do not be confused by color, which makes them similar to parts of United Chemi-Con.
Cable 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 cables are
notaa good choice for a modern PSU because there is only one SATA connection
here. You will not be able to provide electricity for a configuration with a
HDD and an optical drive without adapters. The cable is not long enough for a
small computer case.

Specifications
are not impressed. Enhance FLEX-0130B can only bring 250 out of its 300W load through
the most important +12 V rail. The relatively high load capacity of the other
rails is good but hardly really necessary for modern PCs.
The efficiency is not high, too. The basic
80 PLUS certification is even not a mainstream feature anymore, at least for
the full size ATX's products.
Compatible UPS
Working together with APC SmartUPS SC 620,
this PSU is stable when powered by the mains at full load up to 300W. And, it
can be transferred to the UPS batteries at load up to 255W.
By the way, because we are testing the
low-wattage PSUs, we check out their UPS compatibility at loads lower than
those we usually use for full-size ATX PSUs, i.e. down to 280 watts.
Cross-Load Voltage Stability
The
graph shows the overall voltage regulation
The graph shows the overall voltage
regulation, but the PSU is good enough in terms of typical loads: the single
reference PC configuration that meets the PSU’s wattage is in the green zone.
It is only at unrealistically misbalanced
load combinations (high load on the +3.3 V and +5 V rails and lower load on the
+12 V rail) that can make the voltages go out of the permissible limits.
This is a very good result for a PSU
without dedicated voltage regulator It is in the typical range of loads, the
voltage is stable the most.
Output Voltage Ripple
The
high frequency ripple is visible on every power rails
The high frequency ripple is visible on
every power rails, especially on the +5 V and +12 V rails, but is always within
the permissible limits.
It’s
the same picture at the double mains frequency
We can see a same picture at the double
mains frequency.
Temperature and noise
PSU
is cooled by a 40x40x20mm ADDA AD0412XB-C51 fan
PSU is cooled by a 40x40x20mm ADDA
AD0412XB-C51 fan. As opposed to ADDA fan of the Seasonic's M1U, it has 5
instead of 7 wing-blades and has a rated speed at 8500 RPM.
As with Seasonic’s Mini 1U series, the
configuration of the fan grid and the small size of the fan prevented us from
measuring the speed. Subjectively speaking, Enhance FLEX-0130B is more noisy
than the above-discussed Seasonic PSUs, becoming audible at a load of 100
watts, uncomfortable at 150 watts and downright loud at 250 watts and higher.
Therefore this model can hardly be recommended for those who prefer the quiet
components.
Efficiency and power factor
Enhance
FLEX-0130B was 80.5%, 83.6% and 82.7% efficient at reference loads 20%, 50% and
100%, respectively.
Enhance FLEX-0130B was 80.5%, 83.6% and
82.7% efficient at reference loads 20%, 50% and 100%, respectively. That's
enough for the basic 80 PLUS requirements but falls short of the 80 PLUS Bronze
standard. The peak efficiency of 84.8% was observed at a load of 230W.
The power factor was almost 99% at full
load.
