- AMD Phenom X2 550 clocked at 3.1Ghz
- 500W 240v PSU (I *think* this may be a problem, but it meets the minimum requirements)
- AMD Radeon HD 4350 (yes it's rubbish)
- 8 GB DDR3 RAM (various brands)
- PCI Firewire Card (not sure what brand or power usage)
- PCI Wireless networking card (not sure what brand or power usage)
- Windows 8 Consumer preview
I'm my small feable mind I thought that I had plenty of juice left over as the 4350 only takes up 25w, and the CPU takes up 79w. However when i installed a AMD Radeon 6870 which is a 151w monster I felt the current PSU would be able to supply enough power.
However when I start up the monitor (on both ports including the HDMI when I plug it into the TV) show NO SIGNAL.
I pop in my 4350 and bingo everything works fine.
Do I have a faulty card (just got it today) OR is my PSU inadequate for the awesome power of a 151w card? Or am I being a dufous?
PS: Yes I did uninstall the driver for the previous one (I think), although it seems to have automatically reinstalled it when I booted up windows again. Any friendly advice would be most appreciated. I really hope it's an insanely silly and simple reason that I've overlooked, and not that the GPU gods have smited it with static, or I need to but a 750w PSU oh and yes I earthed myself, and handled it all like a bomb squad operative
Any 500W+ from Corsair, Antec, XFX or seasonic will do the job other brands may be OK but check the reviews 1st (from review sites not customer reviews). Its not 100% the problem though what power supply do you currently have? Also have you connected both the 6 pin power connectors on the card to the PSU? Do the fans on the GPU spin?
BTW have you tried unlocking extra CPU cores I have the same CPU running 4 cores at 3.7GHz.
