ePower Tiger 1 KiloWatt Power Supply Review - PAGE 4
J. Micah Grunert - Tuesday, March 6th, 2007


Perhaps the first aspect of the e-Power 1 KW supply that I should focus on is the modular connections.

These connectors or plugs are call Din connectors. They are just like a PS/2 mouse or keyboard connectors or the old school AT keyboard plug (looked like a really big PS/2 connector). These specific Din connectors on the e-Power supply happen to be a little more industrious most. They feature a small threaded ring nut that you spin on ensure that the plug will never come lose. Now I've seen PSU mods where people have hacked apart a supply and rebuilt it to use Din connectors or something similar, but why re-build when you can simply buy. e-Power did a great job with these connections and was even wise enough to use keyed connections - an especially thoughtful design implementation since I've often enough complained about power supplies that didn't help the end user keep their cables easily sorted out.  This prevents the end user from accidentally hooking anything up incorrectly. I could go on, but simply saying that these connectors are great should suffice.

As for the body of the supply itself, it comes with this sweet back chrome finish, though more of a really shiny Grey or very dark silver. One thing that you might notice is the size of the e-Power 1KW. It is in fact larger than the conventional ATX form factor power supply. Typically, a power supply will measure X150(W) by 160(L) by 86(H) millimeters, while the e-Power lives in that larger category of 150(W) by 180(L) by 86(H) millimeters. It may only be a couple of centimeters longer than the conventional power supply, so I might be hesitant to toss this supply in cases that were too small.  Some of the newer mid-towers coming out now are fairly tightly spaced so watch out there.

On top, the 'Silent Engine' buttoned fan grill helps to protect curious fingers from the dual ball bearing fan. Typically, C case fans will of a bushing design; a smooth rod spinning in a smooth cylinder. Bushings work, but do wear out far before ball bearing fans and usually can't reach the same speeds as ball bearings. We can also see some rubber bushings on the four mounting points for fan, helping to reduce vibration and noise.

Something else interesting is the 'Combined' 12V rail indicator LED. This power supply has the capability of switching between independent or combined 12V rails. Handy when power draw peaks.

I couldn't help but notice the larger power switch e-Power used. Remembering back to my review of the Cooler Master RS850EMBA power supply, Cooler Master had said that the inclusion of a switch was not possible due to the high current draw of their supply. Something to the effect that no switch could handle that high amperage. Looks like e-Power found one no problem.

Now let's take a peak inside this beauty.  Four little screws later and we're in.

The interior design of the e-Power 1KW supply is noticeably clean with a minimal of loose wire and or clutter. Incredibly important to help ensure proper ventilation and cool operation.

I really like the heat sinks for the SCR's. Properly cooling SCR's (Silicon Control Rectifiers) is critically important as they are responsible for filtering and augmenting the current that runs to your PC. They can get hot and burn out if not properly cool. These heat sinks are of a far better quality than most and will probably cool far better than most.

We can also notice that the wires leading and soldered to the interior I/O panel are of a heavier wire gauge. The thicker the wire the better.

The triple transformer is pretty common nowadays and simply allows for higher output. There are plastic shields to prevent arcing of electrical components and a general sense of quality/care with regards to the interior engineering of this particular supply.

I could go on and on, but I shall simply say that the e-Power 1KW supply is built like a brick house. It's absolutely solid and should last for years.

Maybe now we can see how it preforms in CrossFire testing.
