How much power do I need for a GTX590?

[Nab]

Ok, so before I order my GTX590, I have a question regarding my Power supply. Since a GTX 590 is a hell of a card. Will a 600Watt ( 80 Plus Bronze ) be enough to power the card withought overclocking it for the time being?

Computer specs in sig.

No offense dude but why would you need a 590? a 580gtx or hd6970 can pretty much handle any games out today and probably most games in the next year or so.

ETA: You would probably need 800W or more.

Assuming you already have 570, are you going to SLI them (I think it's possible?)
If yes, then I think you need more than 600.

It's like saying "Why would you get a GTX 580? You should get a 560ti instead!"


My bet is minimum 750w, 1000 may be overkill but it's worth it.

[BicycleMafioso]

Yes and no.

If you plan on ever benchmarking and stressing your CPU and your GPU to the limit, it's 620w. If just gamingload, 563w.
It's too tight for me, and I'd say no.
I'm also impressed that you run 3x2GiB sticks in dual channel mode.

It's not possible.

I have a 120hz Monitor, that requires double the power to achieve full quality.

going to have to agree with b0sanac here but i would recommend a decent 800w psu

Just saying, 590 is overkill for all games at the moment.

[Potatowizard]

I think the recommended watt peak for a gtx590 is around 700w? I think about its peak the 590 pulls around 600.. so you're pushing it.

I don't run 3x2Gib sticks the sig is outdated I run 2x2 Gib.

Stop projecting your own needs onto others.
It's also a general and untrue statement.

Hey just stating an opinion. Im assuming that OP is using it for gaming, otherwise i apologize.

[Adsertif]

You probably want a 750-850W PSU, 600W is just too close to pushing it.

According to that I only need 500 Watt, something smells fishy here.

As tetris essentially said, we all have different needs. Who knows, the OP might have a 2560x1440 monitor or even larger, and if he does, a 590 would suit him extremely well, especially if he wants to play anything at reasonable graphics with 40+ fps, much less 60. You should meet Cyanotical and Synthaxx and tell them they don't need their video cards.

[Nab]

Again, as people didn't realize. I run an 120hz monitor which requires double the power. That is why I need such a powerful card.

[DeltrusDisc]

I want a 120Hz so bad. x_x Course then I would have to upgrade my video card anyways.... no displayport. >_<

[BicycleMafioso]

Why would you need a displayport to run 120Hz? DVI-D should be enough.
Also, just restating that 600w will work, but I'd clock the CPU back to standard and undervolt it as far as possible. To like 1.15v or further.
I'd then remove the DVD+-RW if you have one, as they soak up a bit.
I'd then NOT run benchmarks, as that would put you above 600w. At least cpu+gpu at the same time.

But you'd still live too close. I hate when people recommend too beefy PSUs, but your case is a warranted one. 750-850w would be another option, so you could overclock.

Underclocking my CPU back to stock sounds a bit rough. Don't want it to bottleneck the GPU. May as well do that until I get another PSU though.

You likely wouldn't bottleneck it.
Yea, it wouldn't be as good as with overclocks.
However, the term bottlenecking is used where one part of ones configuration is holding another hardwares potential back, and not letting it be used to its fullest.
That would likely not happen here. The i5-2500(K) is a very capable CPU, and it should very well be able to keep up with the GTX 590 without forcing the GTX 590 to throttle.
