530W enough?

[pompeybloke]

I am halfway through building a new PC. I already have a 530W Tagan PSU and I want to know how it will deal with the following stuff.

Epox EP-9NPA+ SLi nForce4 SLi Motherboard
A64 3700+ San Diego
2GB 3200 RAM CAS2.5
Western Digital 250GB SATA2 HDD
7800GTX (undecided on make)

I guess it should be OK initially, but if I wanted to add another 7800GTX later on, would it work on that PSU?

It's perfectly fine. However, I really don't suggest getting SLI. Consider this: 1 7800GTX is about the same level as 2 6800 Ultras in SLI. A 7800GTX is about $520. 2 6800 Ultras in SLI is about $1000. SLI is only for uber-rich people that always MUST have the best at the time. By the time you save enough money for a 7800GTX, a newer card will be out that outperforms your 7800GTX's...

7800GTX isn't a power hungry monster like the 6800. That PSU will be more than fine.

OK thanks.
I wasnt considering going SLI for a long time, it was just something I was thinking about for the future.

Even in SLi, you've got enough power. The system in my sig uses a 500W PSU, without any power issues whatsoever.
