Ultra gives lifetime limited, corsair gives 5 years. I see corsair has 6x6pin, but ultra has 4x6pin and 2x8 pin.

I plan on running e8500 on rampage formula asus mobo, 9800gtx and then upgrade through evga to a 260 or 280 in a few months, or whatever new one comes out.

I know my board is a crossfire board, but I like nvidia cards better atm, and the corsair is capable of handling crossfire and sli, while I can't find any info if the ultra can handle crossfire, albeit being sli certified.

So, help me decide because I can't...my good friend loves ultra, and corsair seems pretty decent. So I like the idea of having lifetime limited, but if in the future I choose to go crossfire, can the ultra3x handle it?

corsair and it is cheaper

Corsair or Ultra? You're joking right....
Corsair, no contest.

Why exactly are you getting a 1000W PSU? For a single GTX 280? That's overkill big time unless you're planning on going SLI 280s (which again, you can't do on a X48 motherboard). A TX750 would be more than enough for a single GTX 280 (or any single graphics card, including the X2 and GX2).

My suggestion to you is to do more research. The HD 4850/4870 are currently the best buys and you'd have room to upgrade to multiple graphics cards in the future.

ultra is a little shady when it comes to power supplies (or anything for that matter).

My suggestion to you is to do more research. The HD 4850/4870 are currently the best buys and you'd have room to upgrade to multiple graphics cards in the future.

+1
especially since you have the crossfire compatible motherboard, and for the fact that the 4850 trades blows with the 260 and the 4870 trades blows with the 280 for significantly less $

A 9800GTX and the GTX 260 and GTX 280 each require two pcie connectors. One 6 pin, and one 8-pin. Any QUALITY psu that has those (4)connectors should be sufficient. In your case, a 6 pci-e psu is overkill.
I don't know about Xoxide-Ultra, but Corsair is a quality unit.

As a better alternative, may I suggest a PC P&C silencer750

for half the price.

Don't worry about 6 or 8 pin connectors. Quality PSU's will make half of the connectors a 6/8 combo type, which is exactly what you want. The vga card package will also include a 8 pin/molex adapter if you should happen to have an older type PSU.

Either of those PSUs is way overkill, as has been said a few times.

Also I like the killer price on the Silencer 750, it's a solid single RAIL Seasonic built PSU. Here is an even cheaper price for it, it's a steal.

List Price: $199.99
Our Price: $129.99
Instant Rebate: $70.00
Mail In Rebate: $30.00 Expires 08/16/08
Final Price: $129.99 ($99.99 after MIR)

The Corsair has 6 of the 6 pin PCIe and 2 of the 6+2 (8) pin PCIe connectors.

While Ultra does have a poor name with their low end PSUs that is not the case with the X3 series. The X3 1000W is made by Andyson and I believe they are primarily a server PSU manufacturer. The X3 1000W is a solid PSU, and gets the same high score as the Corsair, it's really a toss up with maybe a nod to Corsair.

Say I decided to get 4850 and eventually two for crossfire, wouldn't i need a bigger psu then, because I am planning for the future also, so perhaps the antec 850?

 

[spuddyt]

you would need a bigger PSU, but nothing near 1000 watts, as has been said before, a corsair Tx 750 will do fine for 2 4870's, let alone 2 4850s....

 

[Zorg]

Two HD 4850 in CF draws ~199W or ~16.6A.

Using the single rail Silencer 750W above you would have 60A - 16.6A = 43.4 amps left for the rest of the system, which is a hell of a lot.

You could easily use a PC Power & Cooling 610W and have 49A - 16.6A = 32.4 amps left for the rest of the system, which is way more than enough.

The sale is extremely good, but it's over on the 15th.

I would probably spend the extra $20 for the 750W for future VGA flexibility.

I own the Corsair and I can vouch for it, and I want to set the record straight: it has 3x 6 pin and 3x 8 pin connectors.
