I am in the market for a new power supply (PSU), and I want one that be able to sufficiently provide current AND future parts. My current configuration is:

AMD Athlon 64 3800+
nVidia GeForce 7900GTX in SLI
ASUS-A8N SLI Deluxe
Corsair XMS RAM 2GB (2 x 1GB)
Plextor PX-760A
Seagate HD 300GB SATA
Antec NeoHE 480 (and I recently discovered this power supply has been discontinued)
2x Cathodes
1x watercooling pump (very low voltage though)



Now, I have thouroughly been researching various brands and models of PSU's. I found great articles on how to choose the right one for you, and how price relates to quality, if at all. and have come down to 3 choices:

Thermaltake Toughpower 750W (or 850W?) (high-efficiency, industrial grade materials)
OCZ GameXstream 750 (similar to above)
Antec NeoHE 550W (efficiency >80%, stable Rails)

My most likely choice of those 3, (4 if you include the toughpower 850), is the ThermalTake Toughpower. However, with the release of the G80 series (like the GeForce 8800's which requires 4 PCI-e cables for SLI), the Toughpower 850 would be good for future products like the G80 series because it includes up to 4 PCI-e cables. I have to choose either the Toughpower 850W or 750W, and there is a BIG price gap, almost $100!

Like I mentioned before, I want a power supply which will last me for a long time. As we all know, technology changes at an exponential rate.

So, my question is:

Which of these (or if you know better ones), power supplies is the best for current and future PC products?









P.S. - I think it would be nice if this topic of Power Supplies would become a discussion as well
