You could actually run embedded XP on a normal PC, however the cost would be prohibitive as you have to purchase an initial installation kit/license which is around $1000 US (from memory) and then pay for each embedded XP OS you create with it. You actually create the image with whichever components you require from a database and can include third party applications as well. Embedded XP is based on XP Pro and software that runs on XP Pro should be able to be run on it. This software is designed for appliances and dedicated machines, in our case we are looking at it to run Digital Video Recorders (multi-camera surveillance machines) that we manufacture but I still haven't had a really good look at the trial versions we have as it looks quite complex by the time it checks all dependencies and so on. Hope this helps !

Thanks once more ! I did a conservative and max type of calculation and guessing at the A/V cards consumption I get a figure of around 380W (with no margin for error of safety factor) so I guess I will need the 500W PSU I have ordered ! Regards, Bane66 NB; The whole thing would have been easier if the supplier/manufacturer we buy the A/V cards from sent me the specifications for the cards and system requirements as I had originally asked, but hey....you get that ! Thanks again !

Thanks, looking at it now !

Does anyone know of a good guide or calculator for ATX power supplies. Have just built a new DVR (Digital Video Recorder) and I think my PSU is causing me problems. System jams, reboots or corrupts the screen giving message that windows files are corrupted (which they aren't). At one stage it kept stuffing my AGP card giving an error that the drivers could not be loaded, but was fine when I removed the A/V capture cards. I am currently running a 300W PSU but have just ordered a 500W one just in case. The system is as follows; 19' Rackmount 4U case (300W PSU) Asus P4B533 motherboard 512mb PC2100 Amicroe DDR ram (1x512) Chaintech 64mb Geforce 4 MX440 AGP Three (3) Western Digital 200GB 8mb cache HDD Lite-On 52x52x24 CD-RW 1.44mb floppy drive 120mm Case Cooling fan Three (3) 50mm case cooling fans and Four (4) VG4C-RT Cards (Realtime 4 channel video/audio capture cards with 2 cooling fans on each and external power connectors using HDD plugs) If anyone knows of a good guide, calculator, has had a similar experience or knows something that may help I would greatly appreciate it !
