Hello everyone!
I am having a hard time choosing a proper PSU for my planned build.
Intel i5 4590
Gigabyte GTX 970 G1 Gaming 4Gb
16 gigs of Corsair Vengeance RAM
I will be using a Cryorig H7 to cool the CPU (I know its not a must-have with a non-oc cpu, but i like my system cool and quiet, also i want it to last at least 5 years)
Also, i am planning to use three 120mm fans for good airflow in the Corsair spec 01 case
My cpu is not overclockable, but i am planning to OC the GTX 970 as much as i can!
Here comes the tricky part: i used many different psu calculators to determine how much power ill need. The results always showed me that the load wattage of a system like this should be around 380-400 watts. Now i know i should add some headroom to that, and finally i decided that a decent 550W psu would be enough for me.
Then i read, that for a safe headroom, a gigabyte gtx 970 gaming should have around 600 watts.(remember that i will oc it as hard as i can)
So my final question is, will a decent 550w psu (Like the XFX Proseries 550w) be good for my build? I read somewhere that psus are most efficient at around 45-50% of their max wattage, what does that mean?
My budget for the psu is around 60-70 bucks, but i am willing to spend around 100 if it is neccessary.
Thanks in advance for any help!
