430w Psu

with

7770
http://www.newegg.com/Product/Product.aspx?Item=N82E168...


Yeah I know cutting it close but will this work, Not asking what would be better because I would love a 1200w psu but I don't have the money for a new psu and thats the one I got.

Using a 4650 right and I can't tell what the power consumption is its different for each site.

more info
I got 1 fan, asus 79 evo, 4gb ram, 3core phenom 3.3ghz.


I noticed people in comments using 450 gtx with it.. pretty sure those are more power hungry then the 7770, Though I am not tech pro.


Also did this little power consumption calculator was around 299w

I'd get a CX 500 v2. That PSU looks dead dodgy.

Guess that was not specific enough to say this is not a compromise, this is will it work not what is better.

If the PSU actually outputs the amps it claims, you should be able to run it.

Calculating the power output on the 12v rails (good PSU's only have one), you should get a max of 348W (The supply has no business being called 430W).

Assuming worst case scenario.
AMD CPU: 125W
Mobo: ~30W (much likely less)
HD7770: tough to find out, but 100W at absolute most (likely much less).

Total Draw on the 12v rail: ~255W

You should be fine, though that supply is fairly low quality. I would advise replacing it as soon as you can to a proper unit.
