Which psu for sli?

[imported_Wanger]

Ordering a computer from monarch soon so my choices are a bit limited

Asus sli premium
x2 4400
2 gb ram
1 80gb and 1 200gb hds
audigy sound
2x 7900gts
nec 3550 dvd

thats about it I think so which one of these two would do me proud

OCZ PowerStream ATX 2.01/EPS SLI 520W 119$

Enermax Liberty ELT500AWT ATX 2.2 500W SLI 108$

They have a couple other ones for around 160$ that are 600W but would rather stay closer to 100 if I can.

You should be fine with either of those. There both decent brands and will give you a constant supply of power. See which one has the best connection options on it (sata, pcie power) and buy the one which fits the bill best

I have this in my system and have had no issues with it.
