Talismoon Xbox 360 PSU Energyzer quick review

Tired of the noise that my "Falcon" Xbox 360 produces, especially the PSU, I had a look at quick fixes. Soon, I stumbled upon the PSU Energyzer, which allows you to use a standard 20-pin ATX PSU with your Xbox 360, and the use of a silent PSU.
What I was to find out soon is that the PSU Energyzer is quite tricky.

One thing I was afraid when I ordered the PSU Energyzer off from eBay, was that the use of an ATX 20-pin plug was going to be a problem, since it only has one 12 volts, yellow wire.
The "Xenon" 360 drains 16.5 amps from the 12v line, so this is a huge issue for a cheap PSU, even more for a single wire.

If you pay attention to the evolution of ATX PSUs, you know that, currently, you have at least a dual 12v, dual ground plug, known as the ATX 12v connector. This connector was introduced by the time of the Pentium 4's introduction and has since remained as standard. It was designed to supply a dedicate power source to the CPU, which consumed about 90 watts at the time.
With the recent 125 and 140W CPUs, the ATX 12V plug has been updated to 8 wires, four 12v, four ground, to accomodate these power requirements. Although most 125W CPUs can work fine on the standard 4 wire connector, problems may arise. Sometimes, failure to comply with the requirements can be disastrous.

I was obvisouly astonished to find that Talismoon hopes that the PSU Energyzer will be able to feed 198 watts - that the "Xenon" Xbox 360 pulls from the 12v rail - through one wire. Still, I gave it a try.
The short run wasn't disastrous but the 12v wire was considerably warm(it should be completely cold, as is usual. A warm wire indicates thaat it's struggling to keep up); the console itself worked fine for the short run it took. Remember that it's a "Falcon" model, which only churns 170.4A maximum, from the 12v rail, not a "Xenon", for which the PSU Energyzer was designed to work with.

I didn't liked it, so it's going out of service until I mod it somehow, you know, the proper way. Maybe even using the ATX 12v plug. You should do the same.
Some people who bought it, obviously, had problems, as an Amazon customer explains:

Ive purchased 2 of these thinking that they were a good low cost alternative to replacing the power supply. I have numerous good pc power supplies . Both of these talismoons practically caught fire they got so hot. I managed to salvage one but have to keep a fan running on the connector and my 360 frequently locks up. I will be throwing them all away and purchasing a microsoft oem power supply.

Although the PSU choice might have helped the disaster - some might have better wiring, some are more "compatible" and might work fine(as I explained before) - this is definitely a fault by design. No electrical engineer, in it's right mind, would design this and hope it lasts for long.

At the very least, Talismoon should have used the ATX 24-pin connector, which provides two 12v wires. That could have been enough to solve most problems. The connector that plugs to the Xbox 360, by standard, uses 3 wires. The standard ATX plug coupled with the ATX 12v plug would have perfectly fit that.

The PSU doesn't turn off

The other problem with the PSU Energyzer is that it doesn't turn off the PSU as it should, it just stays on as long as it's plugged to the wall.
This might be a problem of an earlier revision, as some people claim this doesn't happen on newer versions. The rest remains unchanged.

On a final note:

If you do plan to still use the PSU Energyzer, do check that the PSU you choose can provide, at least, 1 to 2 more amps than what the Xbox 360 requires, which is:

Xenon/Xephyr: 16.5A
Falcon: 14.2A
Jasper: 12.1A

Also, be sure that this is on a single rail. Most modern PSUs have different rails for the 12v, sometimes as much as four, with different amperage. Most importantly, the ATX 20-pin plug usually gets a weaker rail.

Conclusion

Stay away. Unless you want to mod it somehow, you shouldn't use the PSU Energyzer. It may catch fire and possibly damage your Xbox 360, or worse. The lucky ones only loose the adapter itself.
The issue with the PSU not turning off is also another reason to stay away; to wait that Microsoft finally releases a passive PSU, the one worthy of a media center.
