Is my PSU big enough?

[PhegMan]

Hey guys,

 

Just wondering whether or not I will have to upgrade my PSU with my recent upgrades in my system.

 

Currently I have a Corsair CX600M (600 Watt, 80+ Bronze)

 

My specs:

CPU: i7 3770

Cooler: Corsair H100i

Motherboard: MSI z77 MPower

Case: Fractal Design R4

Memory: 4x 4GB Kingston HyperX @ 1600Mhz

Graphics: 2x HD 7850's OC @ 1050mhz core, 5000mhz memory

PSU: Corsair CX600M

Fan Controller: Bitfenix Recon Black

Storage: 1TB Seagate Barracuda, 2TB Seagate Barracuda, 1TB WD Green, 120GB Samsung 840 Pro SSD

 

I'm not having any trouble so far but it is 80+ Bronze and PSU calculators (however inaccurate) have given me results around 550W, any reason to worry??

You're good for now, if you want to add another 7850, you'll need to upgrade, maybe.

That shouldn't draw much more than 500w

You are probably fine. To be sure, messure the load on the wall outlett when doing mormal job, gaming and stress test

Very nice 7850 crossfire you have there. Good power for the price.

2x7850 use the same power as a single 7970. so you use 350 - 400W. at wall.
