Recommended PSU?

[zflajs]

To start off there have probably been thousands of these types of posts and I know they can get irratating to some but I only ask for any positive input that you may have.

Now to the point I'd like to upgrade my PC soon. Here are my current specs:

Antec NeoPower 480w
AMD Athlon 4000+ San Diego
BFG 6800 GT OC
Asus A8n Sli Deluxe
2x 1gb Patriot mem
2 hd's
2 optical drives
Various USB devices
LED Front Display

Now i'd like to upgrade to a higher end graphics card (7950??) and run a dual monitor setup. I also might get a better dual core processor later on. My question is will my current PSU hold up to a single BFG 7950 w/ dual montior and my current setup or will I need to look for a different PSU? Any input is appreciated.

Easy answer is "NO!".
Check out the power requirements for 1 BFG 7900 GTX OC. It will amaze you.

A 450 watt PSU is getting just too small these days. For a 7950 you are going to have to get an SLI approved PSU, because a 7950 is really just 2 7900's on one card in SLI mode. So the power requirements are going to be the same as running 2 individual 7900 Cards.

I think that the Minimum size PSU I've seen that is SLI approved is 500watts, and it had a HUGE 12v rail.

But more and more of them are coming into the market so the prices are coming down.

Your NeoHE 480W should be fine.

Don't stretch the truth just to make a point. Your current supply is fine.
