Corsair HX620 620w Modular PSU

Looking Inside

Looking Inside

After noticing some similarities between the HX620 and the recently reviewed Seasonic M12's modular system, I was very keen to take a look inside the HX620. If indeed it does share similar internal components to the Seasonic M12 then we should see some good results in our tests over the next page.

After examining images from our review of the Seasonic M12 against the HX620 it would certainly seem that both units use the same internals with only minor changes. The Corsair HX620 does however have an advantage over the M12 - a more sturdy modular connector backplane that should alleviate the issues we highlighted while trying to plug connectors into the M12.

Just like the Seasonic M12, the HX620 has two yellow transformers placed on the centre of the board. The larger of the two is most likely responsible for the +12v rails with the smaller being responsible for +3.3v and +5.0v rails. Placed in between the transformers is a single brown capacitor that actually looks slightly bigger than the one used on the M12.

Corsair HX620 Fan

Cooling the HX620 is a 120mm fan manufactured by ADDA. This is actually the very same fan found inside the M12, however Corsair in their wisdom decided to do away with the 60mm fan also present in the M12 in favour of a quieter power supply. The fan specifications are as follows:

Model: AD1212HB-A71GL
Size: 120mm x 120mm x 25mm
CFM: 85.2cfm
dBA: 39.1dba
RPM: 2200rpm

More information on ADDA fans can be found here.

"For a ~600w unit the sum of £96 (over at may seem a little higher than most other competing products, however as the saying goes - "You get what you pay for", and this is certainly true for the HX620."
