New PSU

[Beneath Karma]

Hello HC, I was just looking for a small suggestion. I am looking to buy a second GTX 580 for my rig around Christmas time. I was just wondering if I will need a new power supply, and if so What would y'all reccommend? Here's my specs:

Mobo: ASUS P8Z68 Pro-V
RAM: 2x G.Skill Ripjaws 1600 mHz 4GB
CPU: i7-2600k @ 4.6 GHz
Cooler: Antec Kuhler 620
GPU: EVGA GTX 580
HDD: WD Black 1TB
SSD: OCZ Vertex 2 64 GB
PSU: Corsair TX 750 v2
Optical: Asus 24x DVD Burner

I assume that a second 580 in SLI will require a beefier PSU however, so suggestions are welcome! :)

I'd get at least an 850 if you are going to SLI 580's, more is always better though as PSU's are most efficient when using ~50%-70% of their max capabilities.

Yeah I'd personally want an 850 in there to be safe.
SOmething like a Strider Plus, AX series from Corsair, Seasonix X series, or High Current Gamer from Antec.
