520W enough for 770/780 under load?

[Hargreaves]

As stated,

 

Thanks.

[aidenrelkoff]

770 sure...maybe

780 not really at all

780Ti nope not happening

[TheKDub]

I doubt it would be enough, the minimum requirement for a GTX 780 is 600w according to their website.

I'd suggest a 750w psu.

The Nvidia user's guide says no.  You need a 600 watt minimum PSU.

[Clyne]

It's not enough, the guide that @DeViLzzz referred to said it's not enough, would need 600w but i recommend 750w or greater.

[soaringchicken]

No way man, go with a 750watt or an 800. Even if it did work the efficiency would be horrible and your power bill would suffer

[AMICLG]

As long as it's a 80+ Gold PSU from a good manufacture and you don't OC/run minimal hardware then it'd be cutting it close but it'd work as it can only pull 250w max at load but never the less I'd go for a 600-650w 80+ Gold.

[SeanBond]

Everyone here is kinda just dumb. You only need a 450W for a 780ti. The real thing is it needs to be a high quality one. A haswell 780ti rig only pulls about 425W while bench marking. 

 

[D2ultima]

Technically it should work... but I would not recommend it.

 

Loaded i7: 100W max

hard drives, RAM, fans, etc: 100W (I know this is a lot for it)

Leftover for GPU: 320W. Should work.

 

Again, I wouldn't recommend it, but if you're wondering if you can wait a month or so till you get a new PSU? It should be ok (as I think you already have it). This, of course, is assuming good power efficiency and a good PSU even; if your PSU has a 520W turbo power or short-burst-power it's probably sustained-outputting less. So yeah, if you can, don't try it. If you still need to buy a PSU, go for clear 600W or higher, just to be safe

 

*sits back and stares at 330W power brick on my laptop and wonders how Clevo did it*

[The Crazed Child]

If it does 520W on the +12v rail then yes it's enough. I'm running a 500w PSU on my rig with an R9 280X, haven't run into any issues so far.

 

HDDs, Optical Drives, fans, etc are fed by other rails.

750W+ for a single GTX 770 system??

You can run GTX 780 in SLi with a 750W PSU.

 

A well-built 500W - 550W is enough.

I'd rather play it safe and have some room for overclocking hardware and so on and if Nvidia says 600 watts then it is 600 watts for me.  OP seriously why **** around here?

[Clyne]

What in the actual fu....650W, 750W for a single GTX 770 system?? What kind of retardation is this?!

 

You can run a system with a single GTX 780 off a 500W - 550W.

Would be better to be on the safe side and allow room for future upgrades also what if the OP wanted to overclock the gpu.

You don't have to be a dick about other people suggesting things.

You know what?  Nvidia recommends 600 watts so wth is wrong with listening to Nvidia?  Also maybe Nvidia has a brain like I do and realizes people will overclock cards like these so they want to leave some room for that?

[VMaxMuffin]

To summarise everyone else's posts, basically "yes, you could, if it's good" but you'd want more for headroom.

[Sintezza]

520W is more then enough for a single gpu setup.

aslong as it is a decent one.

[soaringchicken]

This is something that is stupid to be arguing about, of course you could go with a 650watt and be absolutely fine. I wouldn't recommend a 500watt but it is possible. Everyone keep it cool and leave suggestions without criticising other people's.

[Sintezza]

according to the video posted above, you see that his highend rig pulls arround 425W from the wall.

But thats just what the psu is sucking from the wall.

The psu it self is a 80+ gold one, this means in his case globably 90% efficiency.

This means that the whole computer parts suck arround 380W globably from the psu.

 

Its not even close to 500W.

 

[Sintezza]

I gonna steal this thread, I'm buying a 

MSI GeForce GTX 780 Ti 3GB Twin Frozr Gaming IV

 

I have this PSU:

be quiet! Dark Power Pro10, 850W 80+ Platinum Modulär

Can this handle two GTX 780 TI in the future?

 

yes no problem

[Face2Face]

The reason Nvidia recommends a 600 watt PSU is because they want to make sure there is enough overhead for your system, and there are plenty of people out there that own PSU's like THIS and will try to run this card.  As Tom Logan pointed out above with the card maxed out using OCCT we only saw 430w from the wall. Keep in mind, you have to factory PSU conversion efficiently.  At 85% efficiency would mean this system is only pulling 365 watts under load from the PSU.  A good quality 500 watt PSU would have no issue powering a stock GTX 780 or 780Ti.

They recommend 600W because there are people who like to buy cheap psu's not rated for continuous load. Even a bronze corsair 430W would work. Obviously im not saying run out and buy a psu that would be pushing limits all day. I just mean a bronze continuous 520W should be fine. Even if it's not one of the highest quality platinum rated psu.
