Enermax Infiniti 650W

Introduction
Enermax is another manufacturer that has been in the market already for quite a few years now. In fact, Enermax was the first company to release major retail products, and they actually introduced the first color painted power supply to the market. Enermax as a company has been at the forefront of introducing new technologies and conforming to the latest ATX specifications. Their tight relations with companies like Intel, AMD, and NVIDIA certainly help in this regard.
Today we have the latest model from Enermax: the Infiniti series in its 650W version. The Infiniti series was introduced about a year ago and we saw early samples in Taipei at that time. We were surprised by the high efficiency of the Infiniti when we first had a chance to look at one, and now we finally can review a shipping retail unit. Enermax has also added another new technology with this PSU called CoolGuard.
The label shows three 12V rails, two with 28A and the third with 30A. The lower voltage rails are similarly rated and don't differ much from previously tested power supplies. With the three 12V rails Enermax has taken a different approach to the limited amperes problem than other manufacturers. We have mentioned this before in reviews of single 12V rail power supplies, where some manufacturers have tried to solve the problem of important 12V rails not delivering enough power in high-end system by having a single high amperage 12V rail. With 28A and 30A Enermax has a better approach, since there are currently no components that wouldn't be satisfied with 336W or 360W. Even better is that Enermax lists the real combined 12V amperage (52A), so while each 12V on its own is capable of delivering a decent amount of power, the total between the three rails is less than their sum. Enermax's OCP is around 32A to 34 amps in most cases, even though they list 28A on the label for two of the rails.

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.
