these are my psu's main specs:
+3.3V: 20A
+5V: 20A
+12V1: 16A
+12V2: 16A
the PSU is 350W (220V) with 70% Efficiency (at full load) and this is my config:
+cpu: intel core 2 quad 8300
+gpu: nvidia geforce 210 (i want to upgrade it with r7 250)
+motherboard: asrock G31M-S
+RAM: x2(2GB ddr2)=4GB ddr2
+x1 CD/DVD drive
+ x2 HDD
when i calculate it i found that i need 290W at full load.i want to know if the PSU can handle it or not and if not what will happend if i try to install it if you know that the PSU have those specs for safety:
UL
TUV
CB
 
Solution
You won't come near 290w. At gaming load, you'll be around 125w draw, and with full synthetic benchmarks/stress testing you may top out around 150-160.

That will be just fine. Though I wouldn't go more than a 250.
