Hmmm need to find someone whos buying from the rainforrest, as I have £150's worth of vouchers (seperate cards) but found something I want on a different site
I'll give you £20 for em.

Why not make it interesting and have a raffle?
Nothing, it's just time to move out.
You can exchange them with me if you like?
At least is isnt replacing the windscreen in your own work van in -5c this morning
You need to get out more.AMD recommend a 750W PSU for a single R9 390 and everywhere I have looked has said that my 750W PSU will not be enough to power TWO 390's, however I have done some maths and some tests, and calculated that it can power TWO 390's and my i7, all overclocked...
The power supply is rated for 744W and 62A on the 12v rail, and reviews show that it can supply up to 71A / 850W on the 12v rail within spec and at over 80% efficiency before shutting down gracefully thanks to the protection circuitry.
Each R9 390 (Nitro 8GB) draws 27.2A (326.4W) at absolute peak draw when stress testing, with a 10% overclock, which means 54.4A (652.8W) peak draw from two cards with equal settings.
My CPU draws 10.8A (130W) at absolute peak draw when stress testing, with a large overclock.
Combined with the CPU this gives a peak theoretical power draw of 65.2A (782.8W)
Under typical use when Folding or gaming the GPU's will draw between 17A and 22A each, and under typical loading the CPU will draw around 4A and 8A. All combined, this gives a 12V load range from 38A and 52A (456W - 624W) leaving headroom for things I haven't accounted for, and the occasional full system benchmark, but I believe that other components draw power from the 3.3V and 5V rails anyway.
The system will be run like this for at least 18 hours a day, quite often 24 hours a day.

AMD running to spec?
An F50 has come up for sell near me. Very tempted. Going to have a gander tomorrow. Only done 8k miles.
The spec is 300W and they are running 324W with approximately 10% speed/voltage increase, so they actually are running to spec.
What now Jack?
I'll overclock them until something catches fire, and them email you the evidence.
I'll give you a bell if I need instructions on how to drive a 4 cylinder diesel

I have a 4 cylinder petrol too, how very dare you.
