External Impressions and Cable Configuration
The rugged and very thick material is strongly reminiscent of the Revolution85+ series. The color is charcoal gray, with a platinum-like surface around the fan grille. The grille has an Enermax logo in the middle, with a Platimax logo and a picture of a crown on both sides of the power supply. Our personal preference is that more is less when it comes to logos and such, but others might appreciate the markings on the case.
The modular plugs protrude slightly at the front of the PSU. The PCIe plug sockets have a different color than the ones for the peripheral components. The cable sleeving is high-quality, but the gold and red stripes on the sleeves don't quite fit with the 80 Plus Platinum certification. While it's not likely important for many users, there will be some that dislike the Platimax aesthetic.

The connector configuration is satisfying. Both CPU cables are very long at 60cm. Each of the two PCIe cables reach 50cm. Altogether the model has four PCIe connectors for graphics cards. The eight SATA connectors are not bad for a 750W power rating. The FDD plug, if you still need one, is at the end of one Molex cable harness. The 24-pin and CPU cables are permanently fixed. Enermax prefers a semi-modular connector system for lower wattages; it's only if you buy the 1000W+ models that you get modular mainboard cables. It's an odd distinction, really—are fully modular PSUs someone more for "enthusiasts" that other 80 Plus Platinum power supplies? Does anyone actually detach their CPU/mainboard cables? Regardless, that's how Enermax has chosen to configure this particular model.

call me a newb... but why would I want a power supply such as this?honest question. Won't other computer components will be designed around more standard power supply output characteristics anyway?

PSU is one of the most important components.You don't want PSU to fail on you ever.
It starts with spiky stability and in time components start failing and you never relate it directly to power supply until you monitor those voltages.
Probably everyone looking at this article gone through that until they wised up.
When you just use Word and Excel on your computer, you probably survive with system hanging once a month in a stable environment. But when you push a bit harder on your system, sometimes the result can be a computer burning literally.

Except that more efficient PSU that race for higher numbers tend to be much more complex, which definitely does NOT help with reliability. (at least as far as my personal experience with Enermax Modu 82+ goes, broke within first 2 month, occasional to frequent reboots 2 years later =/)Iketh - Friday, February 10, 2012 - link
LOL NOOBwhat wifiwolf said are the main reasons, but high quality power supplies also lower power bills considerably on high-watt systems (crossfire/sli/overclocking etc...)
the 2 rules of thumb when building your own system is 1) don't skimp on powersupply 2) don't skimp on motherboard. You can skimp on CPU/RAM and everything else because you can make adjustments on those components so that they work, as in megahertz or RAM timings and the voltages to those components, but you can't adjust how capacitors on motherboards and powersupplies deliver said power.
you have to experience the headaches associated with cheap power supplies before you completely understand.

False dilemma.The choice is not only between this power supply and "cheap power supplies".
There are also power supplies at 1/2 the cost of this one that would likely have performance and reliability that would be so similar as to, for most people, be indistinguishable.
Therefore the question of, why would this power supply be a better choice than a good quality power supply that is much less expensive, is a valid question and not one that should be so easily dismissed.
I paid something like $130 for a Seasonic 650 Watt gold power supply and I am not sure what I'd really be getting with this Enermax supply that is tangibly different.

Just checked my newegg order history; I actually paid $120 with free shipping in October 2010 for a Seasonic X650 Gold. It is 1% - 2% less efficient than this Enermax.Let me reiterate that I think it's valid to question the value of this power supply rather than dismissing the question outright.

Well I should have mentioned that I'm not endorcing this power supply whatsoever, just answering his question about "standard" vs good.Minimum quality I use in my own systems is Antec 80-plus bronze.

I good power supply is of course important but its like with CPUs. The top notch model i overpriced compared to what it offers. So yeah, a 120$ Seasonic Gold sure is better value for most people assuming they last the same time (that's the big question as a power supply usually is re-used for the next build).cfaalm - Saturday, February 11, 2012 - link
I guess it's still like what wifiwolf said still. It depends on how hard you think you're going to drive your system. Hardly any of the manufacturers like Asus, Dell or Acer are going to bother with these PSUs. They can settle for anything that goes up to 75% efficiency on 50% load. If you build your own just for fun but still don't drive it very hard, you'll be OK with a "standard" PSU.For everyone else, serious OCing, gaming, heavy duty video and audio etc. you don't want to skimp on the PSU as you know you'll be asking for the last drop of CPU/GPU power your system can muster.

I think the days of the cheap PSU (save maybe for OEMs) is gone. Even $50 power supplies are fairly decent these days.
