I was just thinking aswell are pc power supplies any good for powering amps and if so how would i go about connections as i can get the amp board without casing and power supply for peanuts
No you can’t.
Also you will not find any PC with a Power Amplifier built in, (Apart from a few watts for headphones) due to the power supplies not being up to the job.
A PC power supply also has fixed voltages which cannot be altered, (To maintain a standard) and it is unlikely that an external amplifier will require these exact voltages.
In addition quality PC power supplies are not cheap. (Unless you enjoy listening to a vacuum cleaner)
Hope this helps
PC power supplies are not cheap
Yeah new one cost £260
Of course you can use a PC power supply to power an amp, but it isn't ideal.
PC supplies are generally very high quality / high current - with excellent voltage regulation. The downside is that most have fans that can be noisy, and the usual output voltages (5v, 12v) are too low to run an amp that needs to supply a decent wattage into a 8ohm speaker load.
So, if you want to fiddle about as an experiment you could do it, but I wouldn't recommend it.
Hi busb this is the amp im getting http://www.ebay.co.uk/itm/Class-D-Amp-2-Channel-2x-40W-Tripath-Audio-Pow...
for the money it should run most speakers but if i upgraded the power supply i should get better sq and have more headroom for speaker selection ?
I guess it might be too late but I have a slightly older version of one of these T amps that has a large and very good power supply built in
It works out at about £220 and weighs 4.5 kilo so that is an indication of the size of the power supply , there is also an internal picture in the link .
I have owned mine for about 3 years and it has driven several types and sizes of speaker with no problem at all and sounds fantastic especially for the money .
Electrocompaniet EMC1UP Cd player , EC 4.7 pre , AW120 DMB power amp , PMC PB1i speakers . Isotek Titan / Nova , Nordost SPM speaker cable , Kimber KCAG balanced interconnects .
Linn LP12 Lingo , Ittok lv3 , Lyra Lydian , EAR834P .

im still researching and found this combo http://www.ebay.co.uk/itm/2-X-100W-Class-D-Audio-Amplifier-Combo-Kit-w-24V-350W-Power-Supply-TK2050-/110961571870?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item19d5d3381e
are the switching power supplies good ?
At that sort of money - suck it & see!
A couple of points - it has a cooling fan. They start off being quiet enough if you are lucky but can get loud. Looks like you need a case?

MAIN: Apple TV2, Mac Mini & iTunes Match, CA Azur 751BD or Panasonic P42V20B into audiolab M-DAC, feeding a Primare A34.2 via XLRs, 2x 5m of Atlas Ascent 2 firing up Totem Arros.
ON THE HOOF: iPhone 5S/Sennheiser MM450.
yes i will need a case but thought i would get it suck it and see as you say if i like it then ill get a nice case
Sounds like a plan to me! At that price, you can't go too wrong. Probably uses a 12V fan so are easy to replace. As a general rule, the bigger the fan, the quieter.
I can remember building my own PC. The processor was cooled by a very large Zalman heatsink with 120mm fan running off a fan controller. Got the machine to run quieter than most laptops after lining the aluminium case with panel damping pads, sound absorbing foam, case fan gaskets. The 15dBA PSU wasn't cheap but when the thing woke up from standby at 3am to run backups without waking me - the effort was worth it. Electronics should be like children - seen & not heard!

That's a lot of electronics for £35. If a man in China can make that, ship it to the UK and make a profit for £35, then I don't hold out much hope for the domestic UK electronics construction biz (if there is any left).
It looks great value, and no reason to think the switcher PSU is a problem - after all the whole amp is one big switch mode supply.
Be a bit careful with the specs, it isn't unkown for Chinese firms to be a bit economical with the truth when it comes to performance numbers, but to be honest, for £35 you cant really go wrong.

The majority of the components in your amp will have come from the area around Shenzhen, and it is quite possible that the amp itself was assembled there. Has your house caught fire yet?
I was being a touch facetious....and FWIW my amp was assembled in good old Blighty.
