Do I need to upgrade my PSU?

[PsychoPigeon]

I plan on getting a new graphics card and was wondering if my current PSU would struggle or inhibit my system in any way. It's about 3 years old.

Corsair TX 650W ATX SLi Compliant Power Supply (CMPSU-650TXUK)

My specs:

Intel Core i5-2500K 3.30GHz (OC'd to 4.5GHz)
MSI P67A-GD53 Intel P67 (Socket 1155) DDR3
Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz (16GB)
Seagate Barracuda 7200.12 1TB SATA
Another 160GB HDD
ATI 4890
Cooler Master HAF 932

Going to buy MSI HD 7950

What do you think?

I would say it should still be more than sufficient.

the max TDP of the 4890 is 190W. the Max TDP of the 7950 is 200W. similar power consumption for more performance

i'd say youd be fine with that mate ... ive just fitted a corsair cx600m in myself .. just dont sli it

mine does 552w on +12v

 

[linwelin]

you're good with 650w

On the AMD website (I think) it lists the GPU and the recommended PSU wattage

It's fine.
