And now, a look inside the PSU:
I could speculate as to the OEM that be quiet! is working with here, be it FSP, CWT, or other, but I’ll leave that for more knowledgeable people since my request for this detail was politely declined.
The build quality looks good, though some may scoff at the up to 40°C operating temperature spec (see full specs on the product page, linked here). Still, this unit targets the more value-oriented segment, and is price-competitive with 80 PLUS Gold offerings from Corsair and EVGA.
