Enermax Infiniti 650W

Conclusion
It is clear that the Infiniti is at the moment the best power supply in the Enermax portfolio. It has pretty much everything a user could wish for. The focus of the Infiniti is definitely not the mainstream market but more the high-end enthusiasts. We intentionally tested the 650W version of the Infiniti, since we wanted to show what the lower performing version can provide. A 720W version is also available, but for many users that would simply be overkill. The build quality is very good and Enermax takes no chances with low quality components. The case of the PSU comes with a nice looking brushed exterior, and in combination with the golden fan grille this will be an eye catcher in store displays and possibly inside your PC.
Efficiency Comparison
From the efficiency point of view, the Enermax Infiniti is playing in the top ranks of our comparison list which shows the highest measured efficiency of each unit we have tested so far. Indeed, the Infiniti has a very good efficiency rating over the whole range of input voltages. At most loads it remains above 80%.
Whoever buys an Enermax PSU can also rest assured that they will have enough cables and connectors for just about any conceivable configuration. Enermax is a company that pays attention to detail, and they don't skimp on the extras. As already stated, Enermax was also the first company to provide PSUs with 8-pin PEG connectors on a retail product, long before much of the competition. The Infiniti comes with three 6-pin PEG connectors, one of which is transformable to an 8-pin PEG connector. This is definitely nice for a 650W power supply.
The inside seems to be nicely arranged but we do feel strange about the similar temperatures with any kind of ambient heat. The heatsinks have a decent size and it's good to see that secondary heatsink is bigger than the less warm primary one. The air still has enough space to slip through to the PCB on all sides of the heatsinks which will provide the other components with a little cooling air.
The DC output has been very stable and no rails even went close to being out of specification. The 12V rails in particular are consistently very high with loads of up to 300W, and they never go lower than 12.05V.
Since the Infiniti has been available for a year now, the prices are quite stable. You can get this 650W PSU for about $190 plus shipping in the US. The cheapest price in Europe is about €140 which equals the $190 price in the US. For a 650W power supply the price is definitely not cheap, and users will need to decide if the package offers enough value to warrant a purchase. There are surely other power supplies with similar quality, fewer unnecessary accessories, and a lower price. If saving a Jefferson or two isn't high on your list of priorities, however, the Enermax Infiniti is a good quality offering.

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.
