Hi

Please tell us the amps on the 12V rail on your PSU.. It should be visible on the sticker somewhere.

Also make sure V-Sync is off for your games.

It might be a CPU bottleneck

First 12 V rail is 23 amps... a little bit low. That is around 276 watts of power, which your system might be overusing. You have a second rail, however I'm not 100% if you are even using the second one.

Possibly might be, I would still get a new power supply anyways. Before you do buy it if you want to, reinstall your drivers.
