There is nothing wrong with screened power cable. It seems pointless, but if the cable you are interested in happens to be screened, don't not buy it simply because of that fact.
However, the more critical aspect are the Connectors and the Wire itself. It doesn't make much sense to spend £100 on a 14ga Power Cable, when very likely your system came with a 14ga Power Cable.
Equally (I've seen this product) a 9ga Power Cable is just as pointless.
For reference, there are AWG wires relative to Cross Sectional Area -
16ga = 1.31mm²
14ga = 2.08mm²
12ga = 3.31mm²
10ga = 5.26mm²
_9ga = 6.63mm²
Common UK/EU Wire is -
1.5mm²
2.5mm²
4.0mm²

Speaker Wire in Prespective -How much is Enough? What size speaker wire do you really need? This question can be answered from several perspectives. One is simply Resistance/Unit-Length.

13ga or 2.68mm² -
Speaker Wire in Prespective -How much is Enough? Oddly the one Cable I did NOT calculate, which would have been the most helpful in the UK/EU is 13ga wire, which at 2.62mm², is closest to the common 2.5mm². 13ga (2.62mm²) Copper Cable - 438 Sustained Watts 2200 Working Peak (best guess) 9800 Max Peak Watts Working Peak is unavailable at... www.avforums.com
14ga (2.08mm²) which is extremely common will sustain 279w all day long, with a working peak power capability of 1800w peak. The Maximum failure power for 14ga is 8192 Watts Peak.
To each his own.
