Hey all,

I started out with this build:

ASUS M5A97 Mobo
AMD Phenom II X4 965 BE
HD 7770 ghz edition
8gb DDR3 ram
500gb HDD
500w thermaltake PSU


Everything worked fine, but after a year this is my current build:
ASUS M5A97 Mobo
AMD Phenom II X4 965 BE OC@ 3.8ghz
Cooler Master Hyper 212 evo CPU cooler
HD 7770 ghz Edition
HD 7770 ghz Edition (crossfire)
500gb HDD
500gb external USB HDD
500w thermaltake PSU


I've already discovered I cant seem to go over 3.8ghz on the CPU because my build doesn't have enough power.

Also I'm not getting the performance I think I should.

In games like Battlefield 3 I'm getting 100% CPU usage and only 60-70% GPU usage on both.


Is my power supply causing these issues?

If you power supply cant supply enough power symptom would manifest as crashes and bluescreens. Your PSU has lower capacity than recommended and its not from a top tier manufacturer but in theory it has enough power.

The voltage you stated, did you get that from the BIOS or from software like CPU-z? You could try setting your vcore to 1.5v and see if you can get to 4.0 GHz.

If your CPU is at 100% and your GPUs are at 60-70% that simply means that your performance is limited by CPU, not your power supply.

So thats causing my performance decrease?

I'm running the CPU at the default voltage, it goes from like 1v to 1.4v depending on if its being used or not

What is the model of your power supply? I'm just curious to see how much power you actually have available, otherwise nothing in your question indicates a power supply issue.
