Enermax Infiniti 650W

Internals
Opening the power supply, we are greeted with a nicely arranged interior. The filtering stage is actually located on an extra PCB directly in front of exhaust area (at the right in the above image). A nice detail is that the small PCB is not the same length/height as the main PCB; this means that air will be able to circulate under the main PCB and potentially provide better cooling. The design also means that unlike other designs (i.e. the Zippy Serene), no components are hindering air from coming through, potentially causing some turbulence.
The PFC stage contains the main cap from Hitachi rated at 390µF and 400V. The rectifier bridge also gets an extra little golden heatsink.
The secondary side looks a little crowded, which is a pretty common trait with many other power supplies as well. Most of the cables block the airflow, limiting the ability of the fan to cool components in this area.
All the safety features are supplied by a small chip sitting on a PCB near the cables; this chip is from the Taiwanese company Silicon Touch Technologies, which is the same as most other Enermax PSUs. It works fine and we haven't encountered problems with it so far.

lol.82F =~27C
I have 29-32 (night/day), 75% humidity for ~8 month.
C2D running @ 3.06GHz instead of 1.86, 8800GTS 640MB, 5 HDs on 680i chipset (which is hot). ALL this Air cooled.
almost silent.
the only thing i hear is HDs (specially 15000rpm SCSI head moving).

Haha, doesn't the heat suck in the summer? I'm @ 26-28C depending on TOD and running a lower clocked air cooled C2D w/ an 88GTX, but w/ the PC P&C 610. It def never gets loud, but doesn't have the cool anodized finish either. :D Bring on the winter and it's 22-24C temps!Christoph Katzer - Tuesday, September 11, 2007 - link
Thanks, and before somebody is asking. I do ripple/noise tests but the Infiniti was tested already some time ago. I will add the results asap after I got feedback from the review with actual results (Antec Earthwatts) this month. Hmmmkay?datamogul - Wednesday, July 1, 2020 - link
For psu nostalgics :) Bought this psu unused in ebay and swapped out my evga g3 to use it with a x370 board equippedwith a 1700x and an rx580. The infiniti 650 has been running without problems for over a week. When switching off, the fan briefly but loudly turns up.
