Which PSU should I buy?

George Harris said:Hey there! I really need to swap out my power supply for this setup:
amd phenom 5200 x2 3.2ghz
ati Radeon HD 4670
2gb kingmax 1333mhz ram
an asrock M3A70DE motherboard or something similar
2 hard drives and a burner.
I'm not exactly a total newbie when it comes to PCs😁 , but I need something reliable that can handle this rig without breaking a sweat, because the PSU I'm using right now is basically junk. Thanks!
You can actually find a wattage calculator over at newegg.com
Personally, I ended up grabbing a Corsair 430W, but hey, unlike you, I don't have a graphics card that's going to go hogging an extra 100 watts all by itself!
Efficiency is the real deal here. If it says it's 80% efficient (like, if it's rated for 400W, you're getting 320W at max load), then you're golden. That's actual usable power!
But if they don't list the efficiency rating? Well, there's a huge chance you're looking at some absolute garbage. Those cheap units often struggle to even hit 50% efficiency!
