Do I need to Buy a new PSU?

I'm in the midst of buying parts for my new build and I'm torn on whether or not I need to purchase a new PSU.

Currently I'm using a Corsair 520HX 520W Modular Power Supply to power my system. Below are the specs of the new build:

Motherboard: GIGABYTE GA-Z68XP-UD3
CPU: Intel i5 2500K $180
RAM: G.SKILL Ripjaws 8GB (2x4GB) DDR3 1600
Case: Corsair 400R Carbide
SSD : Crucial M4 128GB
GPU: SAPPHIRE 100312-3SR Radeon HD 6950 2GB

I'll likely use onboard sound, or my existing Soundblaster XtremeMusic card, and my current DVD R/RW drive. I won't be overclocking out of the box, but do plan to at some point.

Will the 520HX PSU (which is 6 years old) be enough to power the new system, or should I look to upgrade to at least a 600/650 watt PSU?

Thanks in advance!

Great psu btw,it should work fine.
Minimum recommended unit for your gpu is a 500W.
Like o1die says!don't plan on any overclocking.

I guess what concerns me is o1die saying "it may work fine if you don't overclock." Prices on XFX Pro 650W PSU's are at $45 after rebate at NCIX. I'd rather not run a build and take chances on not having enough power.

Down the road I will want to overclock. Should I just wait until then to get a new PSU, or should I jump on one of the 65W deals now?

I'd get a new power supply now. The ocz psu 01die listed is great for the price and will be perfect for your system, even with overclocking.

I wouldn't use a 520w ps for overclocking with that video card. It's marginal at best. I like modular ps also, but the good ones are very expensive. If you don't have the money for one, get the one I recommended or similar brand. 650 watt is about the minimum I would use for overclocking with your system.

Would anyone be able to suggest a replacement PSU that won't break the bank, but it also reliable? The 520HX has been with my build for 6 years, but if I decide to overclock I'd like to make sure I have the right amount of power.
