Is the 6770 Efficient Enough to Run Easily on 460w?

which model psu do you have?
the important factor is the amperage on your psu's +12v rail(s). how many amps do you have on the +12v rail of your psu?
normally, one should be able to run a 6770 off a 460w psu. but the psu should be able to provide the current.
btw 6770 is quite efficient.

don't worry, even you overclock it, you will be perfectly fine with 460W (considering that yours is a good PSU, not the cheap one). I run core i5-2500K OC to 4GHz, HD5850 OC to 850/1050MHz, and my whole system only eats 320 Watt max (while running Prime95 and Furmark at the same time).

I'm not actually sure what PSU I have. I've checked but nearly everything on the PSU is in Chinese.
There's a few short series of numbers but I'm not sure what I should be looking for here.
The make is Acbel.

I'd disagree, in general acbels are just ok. They are cheap low end psus but don't blow up like the other cheapos.

Does it look like this:

As long as it's a decent power supply, and you don't have dozens of hard drives, dvd drives, case fans, and other items drawing power. My Phenom II 965 @ 3.8Ghz, 8Gb ram, 1 DVD drive, 1 HDD, Radeon 5770 only draws 215W, I run it on an Antec Earthwatts 380W PSU.
