PSU Upgrade?

[NeverWinter]

Might be looking at getting a second GTX 570 but my current PSU is an OCZ 700w

Currently running:

i5 3570k (currently at stock speed)
4*4GB
GTX 570
2xSSD
2xHDD
1xDVD-RW

Would I be pushing the PSU with an extra card? I will probably OC at some point as well.

Cheers.

GeForce GTX 570
•On your average system the card requires you to have a 600 Watt power supply unit.

•A second card requires you to add another ~225 Watts. You need a 750+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

For each other card (3-way SLI) that you add, just add another 250 Watts and 20A on the 12V rails as a safety margin. What would happen if your PSU can't cope with the load? Here are some pointers:
•bad 3D performance
•crashing games
•spontaneous reset or imminent shutdown of the PC
•freezing during gameplay
•PSU overload can cause it to break down
