Problem with r9 280x
well got myself the above graphics card checled power requirements and it said 500w no problem got a 550w put the card in a relised that I needed a cable converter as it required a 6 block anda 8 block so got the cable the other day plug everytinh in (And yes all cables were the right way etc) . Switched on and all I got from the graphics card was the fan running and the moniter showing no signal . so checked everything and put my old graphics card in and all I got was a hum from the psu . it appears the graphics card had blown the psu , got myself another more highly rated psu pluged the new card in and nothing , I don't know where to go from here , is it possible the grpaihcs card had a fault on it and it blew the psu ?

GFX card needs 500w PSU min, depending on your CPU, the amount of HDD you have, your dvd drive all that is on top of the min 500w the gfx card needs.
I used a power calculator link and it says for a standard config you need min 486w so if you got a low rated 550w it may dip below the min required output.
Best to get a low rated 700 range or a high rated 600 range.
When you put your old Video card back in where you able to take off the cable adapters you got? If it's not that than between replacing the PSU and the Video card something else is wrong.
It's possible that the graphic card could be faulty and blow up the PSU. But I'd say it's more likely that some cable in the computer is a bit loose. Have you checked all the cables?
Trying to reset bios could also help.
If you take the whole graphic card off, can you get the computer to start without it? It won't be usable without graphic card, but if you could get the processor fan to start up then you could rule out a lot of possible faults.
Exactly what power supply do you have? The nominal wattage doesn't mean much by itself. Give the exact brand name and model.
For that matter, what else do you have in your computer? A heavily overclocked CPU will use a lot more power than a simple Core i3, and that affects CPU load, too.
Also, if you did actually "blow" the power supply (*chuckle*), they rarely die by themselves. Good chance the motherboard and/or memory are fried as well.
If a power supply doesn't have the PCI Express connectors appropriate to a video card, that's often a pretty strong signal that the company that built the power supply doesn't think that it can handle the card.
A cursory check on New Egg of 550 W power supplies found 33 that have some sort of 80 PLUS certification. All but two have the appropriate connectors for your video card--and at least one of those two is junk.
