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.

I know they make the Corsair 620HX (which I own; great PSU), but I thought PCP&C manufactured their own... Speaking of which, will we be seeing a review of any Corsair PSUs coming up? They're hot sellers at work, and I'd like to see how they stack up stats-wise to some of the others on here so far.n0nsense - Tuesday, September 11, 2007 - link
Good job with this review, guys.But have to disagree with you. 4/8 and 24 pin cables are short. It's enough for most of users, but it will be impossible to use it with Enermax CS-718 (I'm a happy owner of this one) case or any other case where CPU socket is not close to PSU. Strange thing. After all, it's the same company.
What is really missing for comparison, is Corsair HX620. Which i believe is best choice for this class.
As for Infinity, efficient, but noisy.

I'm not sure the exact length of the PC P&C 610's 4/8 and 24 pin cables, but it's a real close fit for my Stacker going up from the bottom, behind the mobo tray, back through a hole I cut out, and into the plug. The PC P&C 750 Quad/Xfire reviewed recently has 45CM cables as opposed to the Enermax's 50CM. Still, I think it'd be nice to have some 75CM cables for that extra wiring origami one might need inside a bigger case like the Lian Li 2100's and such.n0nsense - Wednesday, September 12, 2007 - link
It must.http://rusisrael.com/albums/pic/o/00/00/28/2859.jp...">http://rusisrael.com/albums/pic/o/00/00/28/2859.jp...
Look at the picture. cables have to go from the top most to the bottom.
This is my old config which was running with Thermaltake 470 PSU (can't remember the exact model). But when I replaced MoBo with Asus P5N32-E SLI, i found it impossible to connect 4/8 pin cable. It was to short. My preferred PSU (Corsair's HX620) has 19" (~50cm) 4/8pin cable and i needed to do some customization to extent the cables.

Nice review!Considering I have thought the Infinity line was NOT that good compared to other brands comperable PSU`s!!
It appears as if Enermax did something right!!
very nice review!!

Yup, Enermax has been at or near the top for years. My last 2 PS were Enermax. I just got this very model the Infiniti 650 on Sept. 1st for $163.99 including shipping at ewiz.com. Very nice PS.retrospooty - Tuesday, September 11, 2007 - link
Also... about hte noise. I run a C2D at 4ghz and an 8800GTX overclokced as well all watercooled in Arizona, ambient temps are a warm 82f in my house. No noise at all coming from the PS after hours of load.
