Apparently I need a new power supply. What's the best option under $100? Thanks.

All of those are over 100 though. Is it really worth it to spend that much on just a power supply?

I'm saving up for 2 more monitors.

For under $100, not really gonna find one unless its on sale.

a quality 850 w unit would work, 900 would be a little better.

You really need to look at more like $125-150. Any of the ones UsedPaperclip posted will be fine.

The PSU is very important (it is the heart of the system). Monitors can wait.

Yeah there's nothing under $100 unless you count post-rebate price or get a great sale. SLI GTX 480 Lightnings are going to destroy a lot of poor power supplies that claim near 850W but can't actually deliver that consistently over the long term. Yes, it's worth spending, unless you want to overload a power supply and risk having that take out most of your system.

Cheapest (without considering rebates) seems to be the very good Antec CP-850, at $115:
http://www.newegg.com/Product/Produc...82E16817371024

XFX Core Pro 850W at $120 is another good choice and would actually fit in cases other than a few Antec models.
