According to this guide your 5770 requires a minimum of 650 watts(which I think is a little high) but you also have to remember it's not so much the wattage as it is the output on the +12 volt rail(s).
Also purchasing a power supply with a minimum of a 80% efficiency rating is important. https://www.sevenforums.com/graphic-c...ead-first.html

450W actually, you quoted the Crossfire recommendation.

I do agree that his power supply is on the weak side, and if the specs for it listed here,

POWER SUPPLY - HIGH PERFORMANCE

I'm surprised it runs at all. According to that it only has 14A on the 12V rail; might be enough (barely) for when the card is at idle, but put a load on it and things will start to act up fast.

only happened twice today

Have a multimeter handy? Might want to check that 12V reading,

as if it is anywhere close to the ~10V, then you really need a new power supply. You cannot rely on software for this, and manually checking is the only wya to really see what it is. Ideally it should be +/- 5%, any more or less and you can start having stability issues.

I'm not gonna try anything with the power supply coz last time I did it blew up on me lol, so what do you think the best power supply to get for price and efficiency.

Location and budget would help.

Well i live in QLD Australia and maybe a budget of $100.

No idea on shipping but something like this would be plenty and then some for your current system,

Have any links to places that are a little closer to you?
