Will 500W be enough?

post #1 of 3
Thread Starter 
Hi all,
I recently want to upgrade my GPU to an Radeon HD 7850. But the problem is I am not sure if I'll need more power.

My current rig is:
8GB DDR3 RAM (2x 4GB ram)
intel core i5-3470 @ 3.2GHz
2x HDD
1x dvd/cd rom

And I'm currently using Cooler Master Thunder 500Watt PSU with 85% efficeincy
Would my current PSU still work, if not , what PSU would you recommend

Thanks in advance! biggrin.gif

The 7850s aren't that power hungry, you should be fine. My rig with an OC'd I7 and a 7950 can just barely pull 500 from the wall. 2 HDDs, SSD, 1 DVD drive, 4 fans.
