Since I built my PC I added more things to it and I was wondering if it is time to upgrade my PSU. I have a 550 Watt supply and this is my rig:
CPU: Intel i5 2500k OCed at 4GHz
RAM: 16 GB 1600MHz
Video Card: GTX 670
MoBo: Asrock z68 Extreme3 Gen3
CPU Cooler: CM Hyper 212+ with 2 Fans
Case Fans: 3 CM Sickleflow 2000 RPM red LED
SSD: Samsung 840 Series 128 GB
I dont think I forgot anything but if I did let me know.
Your power supply shouldn't need upgrading until you add an additional graphics card in SLI. With the components you're running, you're still not seeing more than 350W actual draw, you still have headroom.
Hope it helps
