ePower Tiger 1 KiloWatt Power Supply Review - PAGE 3
J. Micah Grunert - Tuesday, March 6th, 2007


Where better to start with the bundle than with the box itself. Typical box with impressive ratings and numbers plastered all over it.

When we open everything up we find some very interesting notables with this supply. But we'll start with the cables.  The ePower 1Kw Tiger has some of the most impressive looking cables I've seen to date, and that's saying something!  Coming straight off the power supply we have:

  • Main 20+4 pin mother board power connector
  • 1 cable with  three 4 pin Molex power connectors and one floppy drive power connector
  • 1 cable a n eight pin auxulary power connector

Quite the haul of wires, and just a quick note on each. The main 20+4 pin power cable is standard with its fish net wire loom material. The three Molex power connectors and single floppy power connector coming straight from the power supply are nice, but I would have prefered to have them as a seperate cable that the user could attach/detach depending on what connections they needed. The aux eight pin power connector is standard, though the split apart type are sometimes preferable. No loss on any of these though. The finer fish net wire loom over-top the white cord insulation is great and gives a very rugged and industrial look to the cables. But it's when the modular cables come in that we start to get interesting.

As for the cables that can be attached, there are:

  • 3 SATA power cables with 4 connectors each (12 connectors in total)
  • 1 Molex power cable with 3 Molex connectors and one floppy power connector
  • 1 Molex power cable with a single connection (for AGP graphics or aux mother board power or whatever)
  • 2 PCI-e power cables with 6+2 power pin connectors
  • 2 PCI-e power cables with 6 pin power connectors
  • 1 Physics card power cable with two 6 pin connections

More SATA power connections than most poeple could shake a hard drive at.

There could have been another Molex cable tossed in, but the 4 pin Molex conection is nearing its end. Still, it is useful for things like fans.

 

Having that single Molex power cable is odd, but I can understand it if you're using an AGP card rather than PCI-e graphics.

The two PCI-e power cables are interesting in the sense that they are future proof. There is that nasty rumor flying around the interweb that PCI-e graphics cards will start using eight pin power connectors rathern than the six pin ones they have now. With this 6+2 split pin design we can be rest assured that our killer power supply doesn't become obselete when graphics card manufacturers decide they need more power. But e-Power still saw fit to include a pair of the standard 6 pin PCI-e powr connectors. Very useful if you would be running a pair of XFX 8800 GTX XXX graphics cards. These cards require two six pin power connections. Running two of these cards in SLI means finding four six pin PCI-e power connections. e-Power has got us covered.

A single cable for physics cards! This may not necessiciarlly mean an Ageia PhysX cards, but the third PCI-e slot that is having an even growing presence on modern mother boards. This third slot intended for physics may only be an 8x speed PCI-e slot, but people are using it. Plug in one of those afore mentioned XFX GTX XXX cards to run gaming physics (serious overkill there) and you will need two six pin PCI-e power connectors.

I might also add that despite these modular cables having two different types of outer jacket, all of the cabes have EM (Electro-Magnetic) shielding. This is typically a thin sheet of something like tin foil or mylar (the silver plastic potato chip bags are made from). This presence of metal will help to inhibit any EM fields that may be generated by bundled wires. And those large plastic knpbs on some of the power cables probably have Ferrite cores in them. Again, this is to prevent EM fields from wreaking havock on all those bits and bytes zipping and flying through ypr system. In fact, if you inspect your monitor cable, there's a Ferrite core there too for the exact same reason.

I'm beginning to think that in the design of this power supply (and for its cables specificlly), e-Power maust have gone out and spent a few thousand bucks on the ultimate gaming machine. They assembled it while taking note of what types of cables and power connections were needed. Honestly, few people (if any) could use this e-Power supply to its full potential. But these still a couple more things hiding in our box.

  • User Manual
  • Four SATA power to Molex power adapters
  • Five mounting screws
  • Five velcro cable ties
  • Two tie wraps
  • One power cord

Is that the last of it? Yep, looks like it is. But this is great, all of these bundled extras.

The SATA to Molex power adapters have resolved my earlier issue with the lacking of sufficient Molex power connections.

Velcro ties in all the colors of the rainbow. Well, almost. And a couple of tie wraps (or zip ties or cables ties or whatever others would call them) are pretty common for PSU manufacturers to include.

Manual and mounting screws are standard.

The power cable standard too, but could have been a heavier gauge of wire. As per example, my not so long ago review of the Cooler Maste 850W power supply came with the indication that only their included 14AWG power cord should be used due to the amount of current being drawn by the power supply. e-Power chose to include a regular 18AWG power cable with their 1KW supply. That finer 18 gauge cable means more resistance and lost efficency. So, perhaps e-Power could make their power supplies even better and include power cord of heavier gauge in the box.

That about does it for the bundle, though I know all of you have been wondering about those neato lookin' connectors on the ends of the modular cables. I'll get to that in a second, just when I start to disect this beast.
