Will my PSU scrape in and power my 1080 TI?

[Jack1369]

Hello!

Okay so basically I finally decided to swap my ancient GTX 970 FTW for something a little more powerful. My shiny new Gigabyte GTX 1080 TI Aorus is coming tomorrow. I was wondering if I can power it with my current PSU? Here are my specs

CPU: Intel Core i5-4690k @ 3.5ghz (not OC)

GPU: Aorus GTX 1080 TI

PSU: Evga 430 +80 PSI (I have a 500w Thermaltake litepower one around)

RAM: 16gb DDR3 (no idea the brand. Kingston I think)

Plus 3 RGB Thermal Make fans 120mm

Some old laptop hard drive (doubt it matters it's a laptop hard drive)

And lastly a SSD 500gb Sandisk


Anyone able to give me an idea?


If not what is the cheapest reliable one avalible? I don't want to spend much since I already blown 1k aud on this GPU this week.

Absolutely no chance at all mate. (Either of them)

The 550 will handle it

The 650w would be better

I would have to say No.
And no as in, I wouldnt even try it.
Sure it will boot, and sure you'll be able to run some games, but at some point you WILL face issues.
Your PC might actually shut down unexpectedly, or restart, or worse.

This is actually from https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1080-ti/
So according to Nvidia:

Thermal and Power Specs:

- Graphics Card Power (W): 250 W
- Recommended System Power (W): 600 W

They are not suggesting 600W PSU by accident or kink. The 1080ti is rather power hungry, as you can see from its specs.

Go for a really good 650W PSU, or higher.

I would recommend the EVGA SuperNova 650 G2

But if it were me, I'd actually buy a 750 W PSU, so I can have room for overclocking, should I need it in the future.

OR

80+ TITANIUM, and 10 Years warranty. Pretty awesome if you ask me.

Thanks everyone! I went overkill and got a 1200 watt psu with 60amps+ on a 12 volt rail for about $300aud from my local computer store. Lastly I have a i5-4690 will that bottleneck my gpu? Thanks!

Not typically, no, but in some rare cases it might yes. Its all dependent on the application or game you are going to be running.
You listed the Core i5-4690k in your specs, but you didnt list your motherboard. Depending on whether or not you have a Z-series motherboard, you might be able to overclock that CPU (since its a K model) and get any performance you might need (if you need it).
This CPU will blow stock i7's out of the water, if overclocked properly.

In the case that you dont want to or simply cannot overclock, then you might wanna upgrade to an i7, especially if you can sell your i5 and get some of your money back. I wouldnt recommend that you upgrade if you're gonna spend 350+ dollars on an i7, and just put the i5 back in its box and leave it on a shelf.

Just keep in mind that with some extremely CPU intensive games, and/or with the right mods/customizations to those games, you can basically bring ANY CPU down to its knees. Most game mods are graphics intensive, but there are those that will put a heavy load on the CPU as well. Skyrim is a well-known culprit of this issue.

Of course, it matters a lot on what is your target framerate, what resolution you are gaming on, etc.
If you just want 1080p @60FPS gaming, then I'd say you're perfectly fine. But if for example you must hit 144 FPS for your 144HZ monitor, then you might want some extra juice out of that CPU, to make sure you will usually not be bottlenecked.

Lastly, you might want to look into getting a used CPU. By selling your own, and getting a cheap used i7, you can basically get an upgrade for a pretty low cost (very rough estimate ~100 dollars).
