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

So, the Radeon 6770 needs at least 450w.
I have 460w so I'll be able to use it, but preferably anyone would like to have at least 500w to run it comfortably.
Unfortunately I can't buy the card and a 500w power supply at the same time. Could I get by pretty easily using this card on 460w for a few months without upgrading my power supply?

yes, it is enough to run the 6770 easily but do not overlock it until you get the newer psu..

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).

Tom's 500 SBM OC 955+6870 and was only getting 317w off the socket, running on a 430w psu. But it's a good quality psu and has sufficient amps on the 12v rails which is the most important part. What psu do you have?

As long as if its a quality PSU you have more then enough, then again that's only if its quality....

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.

Acbel usually make a quite good PSU. Even some of the gigabyte and cooler master PSU are Acbel's. I think you will be fine with your PSU. Don't need to change it.

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.
