I think most people buying the 480 will go for even cheaper mobos...

Then you have the stock (not OCed, no increasing power limit!) 480 pulling 7amps on a 5.5amp line.

Someone here on other thread complained his 3x crossfire non-OCed RX480 destroyed his expensive mobo sound card, think what evne one of these will do to the crappy mobos most "normal" people can afford.

I did blow up two X99-Deluxe motherboards trying to OC my 5960X (taking out the CPU as well both times frown.gif ) so I strongly believe too much power can destroy even expensive modern motherboards.

However the stock 480 was only pulling 7A when running Metro at 4K wasn't it? I do think dropping the voltage as low as you can while keeping your particular GPU stable is a very good idea, not overclocking. tongue.gif

Reconsidering, you might be right; if it was a top end card I would only keep it if it was good enough when devolted that I didn't mind running it at a bit lower voltage. Everything going dark in the middle of a game and then needing a new motherboard is NOT good.

The PCI-E specifications allows 5.5A current draw from the 12V (±8%) rail. The 3.3V rail is rated for 3A by the specification. The total allowed power is 75.9W.

Even if the 3.0 spec is true, I'd like to point you to the AMD processor/mobo section.

There's a relatively large number of people still on AM3+/FM2 boards (83xx/6xxx, Vishera/Richland processors) and down. Only the FM2+ boards had 3.0. Just saying... I still have AM3+ myself (Formula-Z/8350)
