Performance Rating

Overall performance would be notably higher with less than 30 mV ripple at +12 V and a longer hold-up time. That said, given its huge capacity, the HELA performs well enough.

Noise Rating

The graph below depicts the cooling fan's average noise output throughout the entire operating range of the PSU, with an ambient temperature between 30 °C and 32 °C.


The DBB fan will get noisy at high loads.

Efficiency Rating

The graph below shows the PSU's average efficiency throughout its operating range, with an ambient temperature between 30 °C and 32 °C.


Average efficiency is high, taking the lead from the Silverstone Strider Titanium, which is Platinum rated on the Cybenetics scale.

5VSB Efficiency Rating

The graph below shows the PSU's average efficiency at 5VSB, with an ambient temperature between 30 °C and 32 °C.


The 5VSB rail's average efficiency is impressive.

PF Rating

The graph below shows the PSU's average PF throughout its operating range, with an ambient temperature between 30 °C and 32 °C.


The interleaved APFC could be tuned further for higher PF readings with 230 V input.
