Need some help with my PSU (GTX 780)

So I have the chance to acquire at GTX 780, but my PSU is this: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817341040&cm_re=OCZ700SXS2-_-17-341-040-_-Product

Do I have to upgrade? Thanks!

The 780 is a 250 watt card

It says your PSU has 72 amps on the +12v rails, which would make it 864 watts. Actually, I'm not sure how they're working that out, maybe someone like shub could tell us...

Anyway, I run a GTX 780 perfectly fine on a PSU which has 50 amps on the +12v rail, which is 600 watts. You can actually run a 780 on an awful lot less than this.

My advice is to buy a cheap Diablotek 900 watt power supply for $14.99 and sacrifice it by throwing it into your nearest volcano. Only then will this appease the great and mighty Shub. He will then bestow upon you great wisdom by posting in this topic.

Ok seriously just wait for Shub's response. He's the power supply guru.

Post #2 is correct. There's nothing to explain really. That PSU has more than enough juice for a GTX 780, which isn't such a power-hungry card to begin with.

A GTX 780 only requires a half-decent 600W (as recommended as per nVidia)--a 700W PSU from almost any company should be sufficient.
