I received an email from Tagan asking me if I wanted to have a look at one of their new units.  Naturally, I said "YES!"  I pondered whether I would get a power supply packages in a briefcaseminiature bureau or hat box.

Much to my surprise (and my daughter's... I told her she could have the box the power supply came in), what I had received from Tagan was not Tagan branded at all!

What Tagan had sent me is a "Silver Power SP-1000E" from the "GuadianX Series."  I'm not sure what "GuardianX" means, but I can tell you that there's no mention of this being a Tagan product anywhere on the box, in the manual or on the unit itself.  In fact, the complete lack of any support or warranty information for "Silver Power" might make Joe Consumer a little worried.

But the letter to reviewers that Tagan had included with the power supply points out that Silver Power is in fact a subsidiary of Tagan.  The letter goes on to state that Silver Power is the "no frills" division, for people who want a good, quality power supply, but don't want to pay for all of the "creature comforts" that makes a Tagan a Tagan.

I pulled the unit out of the very flashy box and sure enough, it's no frills.  Don't get me wrong.  The power supply wasn't gun metal gray with non-sleeved cables like an Antec True Power Trio.  The housing was black and the cables were at least sleeved to the first connector, but nothing too fancy beyond that.

What Chantel is pointing out in the photo above is the very detailed label on the side of the Silver Power SP-1000E.  Below is a close up of this label....

With a magnifying glass we can make out that the number below the "UR" logo is "E166947."  That means this power supply is made by Enhance.  Tagan branded product has always been built by Topower in the past.

As you can see, this power supply has six +12V rails!  Total, they are capable of putting out 960W, which is 96% of the power supplies total output capability.  Below is a picture of the DC output table as shown on the box....

We'll get back to what +12V rail goes to what connector after we do a run down of what cables are included on this power supply later on.  First, let's take another look at the power supply itself.

Right now, let's take some more pictures of this unit....

Looking at the back of the unit, we see that it is cooled by a single 80MM fan.  There is an AC power status light that is red when the PSU is in stand by and green when the PSU is on.

On the front of the power supply we can see a very large honeycomb grill.  Apparently, Enhance feels that a single 80MM fan can cool this thing at 1000W, but a 120MM or larger can not.  Interesting.  If I had seen a pair of 80MM fans front and back I would not have made this comment because a pair of 80MM fans at a very low RPM can actually cool a PSU better than any 120MM fan can at a much lower noise level.  I can't wait to see how loud this thing is.

And here's our bundle of cables.  The sleeving is very nice, but the cables are only sleeved up to the first connector.  There's also A LOT of cables and connectors here, which stands to reason since if you actually need a 1000W power supply, I would have to assume that you have a lot to power.

Type of connector: Silver Power
ATX connector (550MM) 20+4
2 x 2 4-pin 12V connectors (550MM) 2*
2 x 4 8-pin Xeon/EPS connector (550MM) 1*
6-pin Xeon/AUX connector 0
2 x 3 PCIe (550MM) 4
2 x 4 PCIe (550MM) 2**
5.25" Drive connectors (500MM + 150MM + 150MM) 10
3.5" Drive connectors (+150MM) 2
SATA Drive power connectors (500MM + 150MM) 8
Fan only connectors (thermostatically controlled 12V only) 0

* = One of the 4-pin ATX12V connectors is formed by splitting the 8-pin EPS12V in half
** = Two of the 6-pin PCI-e connectors are actually the 8-pin PCI-e connectors with two pins removed

Above, the dedicated 4-pin and the 8-pin that splits into two 4's are pictured.

Here I show the 8-pin split into two.

Above is the 8-pin PCI-e with the "break-away" two pins off to the side.

Here is that same PCI-e connector, but with all 8-pin in tact.

Now let's try to figure out how these six rails are split up across all of these connectors....
