A good PSU for SLI/Crossfire

[VirusType2]

Is this over the top?

I'll be building a PC with at least Dual Core and twin Video Cards.


Any recommondations? If my X1900GT says it requires at least 450 watt PSU, then what do two of them require? another 100 watts?

I'll either be upgrading to two, even better graphics cards or just getting another one of these.

Yes that is over the top, it's a very nice PSU, but way more than you'll need.

This will suit your needs just as well and I've heard nothing but good about it.

This is the one I'm using now.

I've had it a few months, and I love it. The quality was surprizing, compared to the PSU's that come with most pre-built PC's. It came with tons of high quality cables. It's got dual 12v rails, and it's quiet as hell.

I bought it because I had just got my new video card, and my stock PSU didn't meet the recommended requirements. I needed something right away so I drove up to the stores and it was the best one I could find. As a bonus, it was on sale for like $80, instead of the normal $100 at this store. If I would have known I would have needed a bigger PSU, I would have ordered it with my graphic card, and I would have gotten one that could handle anything.

I'm concerned it won't be enough for 2 graphics cards, at least 2 HD's, a DVD drive, mouse, sound, a quantity of fans, and dual core processor. But I hate to buy a better PSU, considering the price of this one, a better one might be $150 or more. I could use that money.


What do you guys think?

EDIT: Oh, and my graphics card is massively overclocked, requiring even more power, especially if I have 2 overclocked cards.

If you're worried about the money, then why do you want 2 graphics cards? Most of the time you're better off getting a better single card.

500watts was just enough for PC with 2 high-end cards for the 1st or 2nd generation. If it's just X1900GTs you might be OK although if it was me I would buy a more powerful unit especially since you have 2 hard drives and want the GPUs OCed.

I want unprecedented untapped power on hand. I want to be able to turn the graphics options up to max on any game, with massive epic battles with dozens, even hundreds of enemies on screen, with a rock steady 60fps.

What graphics card can do that?

I've only had mine a couple months, and it was one of the top cards available.

At newegg, they had a few graphics cards that cost several thousand dollars. Is that what I have to do? Because I think a crossfire configuration will be cheaper.


My brother built some new Intel dual core with custom matched 4GB Ram and 2 gigantic wide-screen LCD displays a few months ago. I intend to build something more powerful.

And you're worried about $150? Pff...
