Can I use one of these power supplies?

I'm building a new system, mainly for gaming. No overclocking will be done.

Two SATA hard drives and a DVD-RW that's in my current system will be reused.
I'd like to also reuse one of my current PSUs (Antec TP-550 or TP3-650) and my GTS 250 until I can afford to get a new video card and PSU.

TP-550: http://www.antec.com/Believe_it/global/product.php?id=M...
TP3-650: http://www.antec.com/Believe_it/product1.php?Type=Mg==&...


This is what I intend to buy:
i7-950
Asus Sabertooth X58
Corsair XMS3 6GB DDR3-1600 (PC3-12800) CL9

Two questions:
1. If I stay with the GTS 250 for now, would either of the PSU's work?
2. When I upgrade to a GTX 470, would that PSU still get me by or is upgrading the PSU a must at that point?

From what I've read, it seems like the TP-550 should work even if I move to a GTX 470.

I can't remember atm how much a power hungry system (i7-900 series based) with a GTX 470 consumes, but it seems highly likely that the Antec Truepower New TP-550 would be able to deal with it easily enough. If I was you I'd double check on review sites like Anandtech, here, bit-tech, techpowerup, hardwarecanucks, x-bitlabs, etc.
Bear in mind that the figures sites like these state (unless otherwise stated) is usually the peak achieved during a stress test which is not typical unless maybe you fold or stress test a lot.

Don't know anything about the TP3-650. Altho I suspect that it would be able to deal with a GTS 250.

The TP 550 will work for the GTS 250
but you will need to use the 650 Watt one when you buy the 470
If you decide not to reuse the TP3-650 you should look at one of these:
EA-650
TP-650

Highest consumption I've found for a system with a GTX 470 under Furmark load was 408W, which is easily within the capabilities of a Truepower New TP-550.

And like I said this will not be typical for most users.

I don't think that Furmark stresses the CPU as much as Prime95
That being said the 550W can run the 470. However with capacitor aging and such it might be better to use a PSU that is a step above like a 600 or 650W
Also pulling out 450W+ out of a 550W PSU is not as efficient as pullling it out of a 600W or 650W PSU

This chart compares a 260 (no 250 was available) and a 470:

http://www.anandtech.com/bench/Product/170?vs=160

The 470 used 408W at the wall under Furmark. That means, even assuming a 90% efficient psu, the ehtire system required <370W from the psu. Add another 70W for kicks running Prime95 as well, and a 550W psu that really delivers 550W can do the job. Even allowing for roughly 80% max use of capacity to allow for aging.

Ante TP 750W is made by Seasonic. The TP-650 is also Seasonic, but not well reviewed. Still, its likely a quality unit. I can't find anything on the TP-550. Both are likely to work well, certainly the 650 will be fine.

Unless you are OCing the cpu or running benchmarks, fast memory is likely a waste of money. Jack says spend $1 more for lower latency and a freebie - and that's reasonable.

OTOH, I'd suggest:

and save $25.
