Do I need a bigger psu?

I recently built a new computer and reused a Corsair VX550 from my old computer.

I'm not having any problems so far but I think I may be on the edge of needing one because I'm getting voltage errors when trying to overclock any further using the Gigabyte Smart 6 overclock program.

I7 860 OC'd to 3.3ghz
8 gigs Corsair ram
3 Seagate internal HDD
DVD-RW
GTX260 Core 216
Antec 900 case with all included fans hooked up.

What do you think?

Not overclocking the GPU at this time but I am planning on upgrading my video card within 6 months to something more powerful.

Then you should use that new video card in the PSU calculator. If you plan on going SLI, specify how many video cards will be used.

Well, if you were gonig to recycle a PSU, you picked a good one to reuse. :) 

What kind of video card are you planning on upgrading to?

Your current PSU is of excellent quality.
With your current build, it is more than powerful enough.

Perhaps the issue is with your overclocking software?
I personally have never had good luck with software overclocking.
Try manually overclocking through the BIOS and see if this helps.

My vote is to keep the PSU. Its a very good unit and should be enough for any single card.

I think that any newer card that you get should use less power than that GTX 260 beast. (unless you go Fermi)

You shouldn't rely on overclocking software to determine power supply voltage's.
Do like the outlaw said and overclock thru the bios.

I'm waiting to see what Nvidia's Fermi lineup is like.

I've been looking at the 5850 a lot as well.

No Xfire or SLI. My motherboard's 2nd pci slot is 4x so that's a waste.

Unfortunately I haven't seen any firm release date or technical specifications for the new Fermi. There are unconfirmed rumors the card runs hot. My best advice would be to wait until the card has been relased and several competent technical reviews are published.
