Guild Wars 2

460w is too low for that setup i think 600w would be nice, it will give u a lot overclocking room for u CPU/GPU aswell. Buy Coolermaster/thermaltake or something like that, certified 80plus power supply is the way to go for a gaming system.

Hi Chang

Do you have a brand name or model number of the PSU?

AMD’s website only lists the “GHz Edition” says ‘500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended’

Also if you were planning to look at new PSU’s the corsair range is well recommended.
something like this: http://www.corsair.com/tx650w.html/

I would recommend a 600W PSU from a good OEM…Seasonic have a real solid PSU series, u can search around and try get them directly from Seasonic, or just do what most do and buy a Corsair. (Corsair TX600/650).

The better the build quality the more likely it will produce the advertised wattage,amperage, and be stable without fluctuation. Cheap PSU’s running near max can end up crippling ur rig with crashes.

You dont have to buy whole new computer, just buy new case that can fit your new psu. Normal ATX case should do the trick. And cases are cheap, you can buy decent case for 50 euros (60-70 US dollars, 30-40 UK pounds)
