Comp Win : Powercolor R9 280 Problem ?

Hi guys,
I recently won a competition here for one of those awesome looking r9 280's which i received today ( yippie ) but after installing in my asus ranger and booted the system i immediately noticed a weird buzzing/whining coming from the card even during POST.

The system is only running a corsair rm 550 so im not 100% if the suspect sound is due to the vrm's not getting enough juice or if it is just good ole coil whine.
I really do hope it is not coil whine as it is extremely loud once in a game even through my sound proofed case.

Any advice would be much appreciated.

*Edit*
Just noticed some severe frame drops in game after only a few mins of playtime also.

Is it not just coil whine ? Isn't the 280, just a re badged 7950 ? if so the 7950's were prone to coil whine, my pair used to whine like mad.
 
I did think coil whine at first as i have had other cards with it in the past but even at POST ?
I had not experienced it at idle before hence why i thought i should open a thread here.
That and the huge fps drops in my games like im currently playing WildStar and with my gtx580 i never had any severe drops that would actually make me stop playing unlike the 280 even though it is by definition a quicker card.

EDIT

I heard about stressing the card using 3dmark or uengine may help the problem what are others thoughts ?
