Default Corsair TX 650W enough?

Hey guys im looking to put together my new build and was wondering if the Corsair TX 650W will be enough as I know the PSU is an important component in the long run.

CPU: Intel Core i7 920
Motherboard: Asus P6T
Memory: Corsair 3GB (3x1GB) DDR3 1600MHz XMS3 Dominator
Hard Drive: Western Digital 640GB Caviar Black
Optical Drive: Sony DRU-V200S 20X DVD±RW
Graphics card: Sapphire Radeon HD 4870 1GB
PSU:
Case: Antec 1200

Im a little optimistic as I need the PSU to last me a long time and possibly another 4870 1GB in the future for CrossFire. Will it be ok? If not any suggestions?

Thanks
Chris

For longevity I would bump up to at least a 750w or an 850w whichever best suits your budget and needs. If you intend to crossfire that rig or overclock cpu (recommended for best gaming performance) you'll need and want the extra power.

I also don't recommened the sapphire card their customer and RMA service has been called "poor" at best. You might consider HIS or XFX which have far better products, warranty and service.

I'd also recommend to bump up to at 6Gb the kits can be easily had for not much more than a 3Gb kit, Canadian Prices: G.Skill - G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)... - F312800CL9T6GBNQ is my recommendation.

Good luck with your new build and if you have anymore questions ask away,

If you decide to go with a 750w PSU this one is a good deal:

It's enough. You could even drop down to a Corsair HX620 for some Modular goodness. As long as you don't Crossfire X 4870X2, you'll be fine with your current PSU choice.

TX650W is plenty for your rig, even for xfire setup (2x 4870). I ran a HX620W with dual 260s and an oc'ed i7 easily.

@ev0: I don't think its the watts (650 vs 750) that matter to your situation, its the amps on the 12v rail which matter most in a dual video card setup. That 650TX Corsair PSU you listed has 52amps and the 620HX has 54amps. Not a big difference, but the 620HX is modular (removable cables), and is generally found to be of higher quality. The 620HX is said to be just as good as many 700w or better PSUs.

If you are sticking to one card the first PS you listed is plenty (the 650TX). If you are adding another card and getting an OC going, it will most likely be enough, but will stress the 650TX. You mentioned longevity, thus the recommendation by Eagle Eye for a PSU a little better.

Ok thanks for clearing that up guys, so to sum up a quality 750W PSU like the Corsair TX would run my potential setup with less stress, making it last a little longer. I live in the UK so im opting for a different PSU but its meant to be just as good. If u guys have the time check it out:
Dark Power PRO 750W - leise und effiziente Netzteile - be quiet! Dark Power PRO & Straight Power

I thought I could get away with the 650W to handle my upgrades and next few builds but it seems I was wrong.

I never heard of that brand. Looks good on paper, but perhaps some of the PSU gurus could chime in. Its a 750w modular PSU, with 6 20a rails.

Specification: +3,3V: 26A, +5V: 30A, +12V1: 20A, +12V2: 20A, +12V3: 20A, +12V4: 20A, +12V5: 20A, +12V6: 20A, -12V: 0,8A, +5VSB: 4A (peak 5A)
