hi,i search on the internet how much amp in the 12V rail the AMD R7 250 1GB gddr5 need but i dint find anything.i have those specs for the PSU ( it's a 350W but when i calculate how i much i need if i use this card i found that i only need 298 W):
+3.3V = 20.0A
+5V = 20.0A
+12V1 = 16.0A
+12V2 = 16.0A
my config:
+ x2 HDD the first one is 255 GB and the other one is 209 GB
+ 2X ram each one is 2GB ddr2 so i have 4GB
+ motherboard asrock G31M-S
+ CPU : intel core 2 quad Q8300 2.5GHZ
+ GPU : nvidia geforce 210 ( i want to replace it)
will it be enough to run the AMD r7 250?

it'll should run off a 350W PSU, even if it is fairly cheap.

Though Quality does sometimes limit the output, it may only be delivering less than 300W, as mentioned before, what PSU is it?

I'd strongly suggest getting a new PSU.

A good 300W+ one should be fine.

20A is enough.

Yes, it should be okay for an R7 250. The 250 is a low impact card (still quite a nice upgrade over a 210) and doesn't even need quite 16 amps on the 12v rail.

Edit: Wait, disregard that. I'm not sure anymore, some benchmarks show the R7 250 drawing much more power than other benchmarks.

I meant to say that the amp was enough also, you should be fine, but later on it would be best to get a new PSU.
