Got a laptop egpu setup with an acer aspire 5755 (i5 2.4ghz sandy bridge cpu w/intel hd3000 onboard) , linked to an ati 5770 radeon 1gb card + PE4H v2.4a + PM3N, at first tried everything to get this working, chainloading the egpu w/windows no ddst resulted in error 12, did the ddst overide and loaded with windows, still error 12, tried the alternate ati drivers listed on a forum, those didn't do anything before or after the ddst overide, finally purchased setup 1.x, had to mess around with it a lot but had success, error 12 was clear however the egpu didn't work still, it seemed the card was working properly in device manager but the ati driver interface wasn't showing a lot of options and trying to disable the conflicting intel hd3000 would result in a bsod (the bsod would say something about ati.dll), finally messed around some more, got the egpu functional by using setup 1.x to recondition the link speed to gen 1.1 (2.5T) then pci compact the egpu (56.25g 36bit) and forcing the igpu to 32bit, card started up finally for the first time had all options in the catalyst control center, other monitor came on properly, no blue screens however very poor performance due to the 2.5T speed, tried everything including playing with the delay switches on the PE4H v2.4a + PM3N to set this egpu to gen2 speed (5T) but for some reason no luck, it seems at gen 2 speed the device seems to work properly with no errors in windows however doesn't function period, could this be a compat issue with the HM65 chipset my laptop has or anyone have any ideas to get this working faster? Tried some performance tweaks as well and even overclock the gpu with no luck , any suggestions?

Wanted to buy a Mini ITX Computer Case with a 250w power supply (its probably a cheap generic one), to hook up my ati 5770 1gb + PE4H, as far as I know it uses one of those 6 pin connectors and comes with a splitter to make it into two normal psu connectors and uses around 80w, will a cheap 250w psu support something like that and whats the worst that could happen if not?
