Ok if good quality psu...Ampere doesn't like cruddy power supplies.
ok thanks. Looks like I ideally need a higher watt psu as I would like to overclock both a little depending on temps etc. I usually go for well known brands like Corsair but there 750w sfx psu is not in stock until next year it looks like. I can get a Silverstone SX700-PT psu, But I've never heard of them?

Silverstone are good.
Always get a bit more power than you need, put your spec in Outervision calculator on max overclock settings.... mine comes out at 716W!
Should be alright but I'd aim for 700W+
My spec isn't that far removed from yours and 600w on a good quality gold rated 10 year old PSU is fine. You need to be overclocking and absolutely smashing the CPU and GPU in synthetic benchmarks to get anywhere near peak power. Note, my CPU and GPU draw 350-400W by themselves when stressed.
Ideally you want your PSU to be no more that 80% loaded because it gets inefficent and reduces the life going over that.

I've searched everywhere are you sure? Sent a pm. I've found the Silverstone one and will go with that elsewhere unless Overclockers gets stock of any higher wattage sfx psu.
