content: So I got an email from a taiwanese supplier. They sell, among other things, power purification modules. I'm fairly new to electronics but this sounds ridiculous. Is it?I did a search in the forum and found one post that mentioned it but not a whole lot about it was discussed.The ebay item number is: 251894650611I tried to attach a picture as well. Hopefully it worked. This is my first post.They have PCIe versions, hard drive versions and more.Surely this is a non-beneficial item to be placing in your PC, correct?

content: Every time I see adverts and eBay listings for things like this I am overwhelmed by a complex set of emotions.Firstly I think "Aaah, that's something I could have come up with and made ass-loads".Such as the guy Kick-Starter-ing "specially designed" tubing for Apple connectors, which shrinks in place to reinforce the cable to connector joint of iPhone 5 mini connectors.Yup. Regular white, normal style, bargain bucket heat-shrink, sold at $19,95 per 5cm.This actually came up when I had just ordered a whole bunch of heat-shrink to tight specs, but no glue-lined white stuff. The glue lined was "too expensive" to diversify in colour, but it would have blown his non-glue-lined option out of the water at only $19.90 per 5cm.Then I, luckily, quickly feel glad I'm not an ass-hole like that. Although it does mean I still ride a 1998 model motorcycle, where the >2013 models are very nice to ride.Although that is also to do with things like my "daily mug" malarkey and the budgets associated with that.One thing has to be said though, cost-for-component this thing isn't even that bad. They actually seem to have put something on there (if the picture is actually representative) and added the trademark half a mu of gold finish that belongs with every decent audiophool scam.

content: So basically this sounds like the old eevblog speaker/stereo box scam. I forgot what the name was... Marc something?Thanks for the clarification. I figured it was hogwash. I actually have one of those premium sound cards mentioned. Thunderbolt unit. Definitely not in need of audiophile-grade power smoothing ram sticks. It was just such a strange find.

content: Looks like a PCB with a fewProadlizerdecoupling caps on it.Amusingly enough, just Google the name or the part number and you'll find that these areknown to failin laptops since they have only 1000 hours life at 105C and they put it right under the CPU socket; the solution is to replace them with an array of regular low-ESR caps.I suppose it could have an effect, if the existing decoupling caps were going bad and marginal already.It reminds me of this:http://www.hisdigital.com/un/product2-388.shtmlQuote from: Fsck on May 21, 2015, 10:18:40 pmHow is that supposed to work without letting out some magic smoke? Backfeeding power into the onboard RAM voltage regulators doesn't sound like a good idea, especially at a higher voltage than they was set to.

The gamers tend to disfavor USB audio as it tends to have more latency, even though it's pretty insignificant nowadays. They also dislike routing the video through a receiver as it may add lag, not to mention that it may require the receiver to be on just to pass through video. (Ironically, the cheaper receivers tend not to add much lag and the expensive ones more lag!)Maybe someone should stuff capacitors inside mains plugs and market them as "audiofool noise stoppers". Sell them for something like $20-100 each (depending on the size of the caps inside) and recommend they be used on all outlets not otherwise in use. Or make them pass though and recommend them to be used on every outlet. (And for the extra touch, recommend stacking a few of them for best results!)
