Need help picking a PSU for my new build.

[Apothys]

I'm in the process of building a little gaming rig. I can't decide on a decent PSU for under $100 Canadian. Im shopping at canadacomputers.com and tigerdirect.ca

I will be putting in a I5-3570K, a Asus Z77 LK Motherboard, Nvidia 680 2GB Video Card. I will eventually put in a second one so please keep that in mind when recommending The rest is fairly standard stuff.

Would a 700-750W Surfice?

Any help would be greatly appreciated.

I'd go with this for sub $100.
Newegg.ca - CORSAIR Enthusiast Series TX650M 650W ATX12V v2.31 / EPS12V v2.92 80 PLUS BRONZE Certified Semi Modular High Performance Power Supply

EDIT: With you saying you're gonna need the power for two, I have a hard time thinking there will be a good PSU for $100 that can power all that and be comfortable. I could be wrong but I say save up. Do NOT go cheap in this department.

650W would be enough?

650w is recommended for a 690, so 2 680s not overclocked will run easy on a TX650. I do agree though, that if you plan to do SLI and overclock later you will want something like the Seasonic 650 Gold or TX750.

See my edit. 650w is enough for your current, with the second card you may need to raise your budget.

I dont plan to overclock. so I guess im ok. would any of these be good choices?
Buy the Thermaltake SMART 650W Power Supply at TigerDirect.ca

Buy the XFX 650W 80 Plus Bronze Core Edition PSU at TigerDirect.ca

Buy the Thermaltake TR-700 TR2 700W Power Supply at TigerDirect.ca

I notice some PSU's are advertised as SLI ready. does that make a difference when having 2 cards?

would this do it?

That tx750 is perfect. The others, no. And don't worry about the SLI ready. Any good PSU will be fine so I'd go with the one.
