Enermax Infiniti 650W

Standby Efficiency


The standby efficiency looks very good and even with 230VAC we see a decent result. Enermax seems to have a very good topology here since we have better standby efficiency than the previously tested Zippy Serene.
Efficiency

We are surprised (and pleased) to see that the efficiency is equal to what we first saw with the first pre-production sample a year ago. We are reaching 86% efficiency under best conditions and even in our stress scenario at 50°C we still measure efficiency results of more than 80%. For loads of between 175~550W, the efficiency will be above 80% regardless of input voltage.
PFC

Unfortunately the PFC again doesn't perform that well, particularly with higher input voltage such as 230VAC. Buyers in the US can be happy about a very good correction factor but the guys in Europe will have to live with slightly lower rates of up to 0.985.

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.
