What's the beefiest GPU you would run on a 450W PSU?

[Ja55ie]

Don't want to upgrade my PSU again, I have the 450 EVGA BT PSU and I am wondering what the strongest graphics card you would put into a system comfortably with this power supply. I know there are websites which you can calculate your required PSU wattage but I want to know in a real world scenario. Also I'm using the i3-8100 at the moment. 

 

Let me know thanks!

Something like an RX 580 would be serviceable on that wattage. Just don't overclock it.

if you're gonna keep the i3-8100, then you can get a GTX 1080 in there comfortably, that wouldn't make sense but you can do that.

 

but if you're planning on upgrading your CPU (like the i7-8700) then i think a GTX 1070 would sit there comfortably.

you can technically you can run it with a gtx 1080ti, but i wouldnt go above a gtx 1070

why not 450 is pretty low power if you where to bump up to a 550 or 600 you could run GPU from a few years ago and not worry about overloading?

Yeah I was thinking ideally an RX 580 just because of the fact that I have a FreeSync monitor but was off-put by the fact that it notes on AMD's website that they recommend a 500W PSU.

Really, a 1080 would be fine? Wouldn't it have some sort of performance hindrance?

Yeah I didn't think a 450W PSU would be sufficient enough for a 1070. 

 

Thanks!

Yeah, I just got the psu with no real intent of gaming but was just curious as to what my options were.

i get it i am still using my HP 2ac8 Gigabyte MOBO hope you find something other than like a AMD Radeon HD 7450

i didn't say there won't be performance bottleneck, but on a 450W powersupply with the i3-8100 there's no issue at all running a GTX 1080, and even overclocking it.

 

but again i didn't say that you should do that, pairing a GTX 1080 with an i3-8100 is a horrible idea.

Manufacturers are always going to recommend more than what is required for their card. As long as you have relatively clean power an RX 580 would work. Many people are running 580s on 450W PSUs and are ok. 

 

I would recommend upgrading to a 600w PSU at some point. If anything just for future use. 

 

But definetly with your CPU I would say get a 580. Putting anything more powerful in doesn’t make sense unless you plan to upgrade your CPU sometime soon.

Yeah exactly, thank you !

Okay amazing thanks a lot. I thought there would be some sort of bottleneck like not getting enough power or something. Thinking of the RX 580.

Okay yeah that's what I was hoping. I believe my PSU is good enough, I've heard EVGA is a decent brand. Yeah that's probably down the line in a couple years or so.

Thank you !

Also the fact that you have a Freesync monitor really seals the deal imo. I need to get me one of those. It’s a godsend when getting CPU bottlenecked in certain scenes in video games.

my Corsair CX 750m is a great PSU and i paid 45 USD for it. check out you local computer supply store they might have a PSU in back in a box that you might be able to get for a deal

Hi im also in about to change GPU in a VS450 psu, what did you experience and what GPU did you pair it with? RX580/GTX 1060 or equivalent?

T hat's a pretty low quality garbage PSU...

I'd rather not use it...

Why don't you make your own thread instread of necroing an old one??

 

The VS450 isn't great, other options like be quiet System Power 9??

I chose a Gigabyte RX 580 - 8GB and it seems to work fine, although I don't really run too many graphic pushing games.

You can get a cheap psu used on eBay.  If you are looking to spend a few hundred on a graphics card <$50 shouldn't be too bad, wouldn't want to damage one of your components with an overloaded power supply.  I got an EVGA SuperNOVA 1200W 80+ platinum for $80.  My buddy got a 650W fully modular 80+ Gold for $40.  Here is a good one
