GTX 780ti with 550w Power Supply?

[Waltee]

As the title suggests I have a 550w power supply - Zalman ZM550-XG to be exact - and I'm planning on upgrading to a new graphics card, possibly the 780ti EVGA.

Now I've heard that it's a pretty power hungry card and I've seen all these high wattage PSU numbers thrown about, but I'm wondering if I'll have any issues running it on my current power supply.

I'm also planning to upgrade to a 4690k/4790k in the near future.

Will I be able to run it or should I opt for a less power hungry card, and if so, any suggestions?

Hi, from Evga itself,

REQUIREMENTS
600 Watt or greater power supply with a minimum of 42 Amp on the +12 volt rail.****

Is this your PSU?

That is indeed the PSU I have. I also couldn't get to the official Zalman website, but the PSU does have 45A on the +12V Rail so meets that requirement.
Just didn't want to buy the card and then be unable to use it is all, and really would rather not get a new power supply as this is only a month or so old as it is.

Just to explain why i think it'll be ok.

A while back i was running an ASUS R9 290X (which as everyone knows, is a nuclear reactor), with an XFX 550W Pro.

Recommended minimum spec PSU is a 600W or greater PSU.

It worked ok as far as i could see.

Hope this helps.

Well it's definitely more insightful than what I was working with already, cheers!

If you can wait, i can look about some more tomorrow, or better still more forum members will answer your questions.

Must go to bed

If you buying new and want to stick with Nvidia , look at the 970 range will use less power and has more vram. As far as i know all the 780 range is End of line

Valve was running a Geforce Titan card off a 450W small form factor PSU. A full sized 550W PSU is more than enough.

It will be fine. It's a decent unit built by Enhance Electronics with a single 12v rail of 45A giving a max of 540w.

Recommend PSU specs are always way OTT for single GPUs, it will be fine.
