Is my PSU good enough for my new system?

[Gerr]

I used Xmas money to upgrade my system. I now have an stock clocked I5 with an MSI P55 mobo and 4GB(2x2GB) of G.Skill DDR3 @ 1600. I have a factory OC'ed BFG GTX260(192sp) as my main videocard and a new BFG GT220 that I use just for PhysX, so not SLI and it is just bus powerered, ie no separate PSU connections like my 260. I have one WD hard drive and one DVD Burner. I have an Antec 900 case with three 120mm fans and one 200mm fan.

My PSU is a Cosair 520W, HX series I think, and is about 2 years old. So far, it seems to be running it just fine and it survived a 30 min stint in the new Batman game with all the details turned up.

Is that PSU good/powerful enough for this system? I was hoping it would make it until tax return time when I would buy a 750W PSU for the system. If it's not powerful enough, what effects would show up?

You should be fine. There's really no need to get a 750w unit.

The power supply you have is fine.

If you want to see what you're pulling from the wall, pick one of these P3 kill a watt's up and run some load and gaming tests: http://www.newegg.com/Product/Produc...82E16882715001
I think you'll be pleasantly surprised.

520W is enough, especially since it's a Corsair, will have most of the amperage on the +12v rail. My rig in my sig pulls about 170-210W idle/normal usage and 300-400W high CPU and GPU load.

If I did the OCCT PSU test it might go over 500W, but there's probably no program, or programs that will ever load a PC to a point that OCCT PSU test simulates. I only got the 750W because I had some spare cash after calculating my biggest (and the most expensive) upgrade ever and so decided to future proof the PSU by getting nice HX750W. Should keep me in check PSU-wise for years to come, even if I ever have the money to SLI/CrossFire later in the future.
