SPECIAL NOTE ON REBATE: This particular rebate offer is good on multiple items-

CMPSU-520HX $15.00 $104.49 FS - $15 MIR = $89.49AR
CMPSU-620HX $25.00 $143.99 FS - $25 MIR = $118.99AR
CMPSU-750TX $20.00 {THIS DEAL}
CMPSU-450VX $15.00 $70.74 FS - $15 MIR = $55.74AR
CMPSU-650TX $20.00 $92.74 FS - $20 MIR = $72.74AR
CMPSU-1000HX $20.00 $220.49 FS - $20 MIR = $200.49AR
CMPSU-550VX $15.00 $84.24 FS - $15 MIR = $69.24AR

The terms & conditions specify the following:
Limit one rebate per qualifying purchase per unique product. Limit one rebate per product line per household. Maximum
rebate $130.00 per household.

What this means-
If you need more than one PSU check Buy.com for the other models listed above. Since there is a maximum of $130 in rebates per household and the rebates above add up to $130, I'm assuming that you can get one of each and get the rebate for it. All models listed and linked are currently showing in stock with free shipping. IMHO the 750TX is the best deal, but if you're in the market for more than one PSU it might not be a bad idea just to take a peek at the others as well. Have fun!

EDIT: I totally forgot about FatCash. Go through the FW link for Buy.com (1% FatCash) and pocket an extra $1.04, brings your final after rebate price down to $82.70. Sorry 'bout that Tim!

I subscribed with the keyword model of this PSU and only got this because you posted it but when I tried to go back and thank you I couldn't find the thread. Why is it that your thread does not come up when I do a title search for CMPSU-750TX or CORSAIR CMPSU-750TX.

I thought it was weird and tried google site search and found it.

For around $75 after coupons and rebates this was probably the best deal for a non-modular top of the line PSU.

Thanks for listing the details of other models. Can't wait for Nehalem.
