Best GPU possible on a 450w PSU?

TrueSpin · 16 Mar 2015 at 22:08

I have a GTX 750ti at the moment, which actually serves me quite well. But without upgrading my PSU (450w - good brand) do I have any options for a mid-range upgrade?

A GTX 960 should be okay.

Boomstick777 · 16 Mar 2015 at 22:14

970 might be ok on 450w, might be pushing it though. If you're at 1080P a GTX 960 will be good and decent price. I've been using a 960 today @ 1440P and it's ok for medium / high settings. Quite surprised.

Decent decent PSU? As in gold/plat - seasonic/superflower?
If so, any single GPU. I've got the SF500W passive, ran basically every card this generation from it, with a 4790k.

I wouldn't even bother with a 960 personally.

Pick up a second-hand 670 for almost half the price and enjoy slightly more performance to boot.

I bet a 980 would work

If it's a good quality PSU, then any single-GPU card will be fine.

I run a 170w (rated) 560Ti on a Bronze 400w PSU. I'm sure I'm nowhere near the limit.

This is my psu. I've always been of the opinion it's fairly decent.

970 would be absolutely fine unless you have a heavily overclocked cpu as well. my 970 (overclocked at 1500/2000) averages about 300w under load with a stock i5 at the wall.

MoonBoots · 16 Mar 2015 at 23:05

What CPU? Is it overclocked?

Bonjour · 16 Mar 2015 at 23:44

That's a good PSU.

290 might be OK. 970 definitely will.

Tonester0011 · 16 Mar 2015 at 23:46

290 will be fine, if you've got an intel CPU you'd be looking around the 350-400w mark loaded up, depends on CPU and whether you're running stock etc.

Meladath · 17 Mar 2015 at 00:36

Any single GPU will be fine on that PSU, bar maybe a super overvolted and overclocked 290X running furmark.

^ as above, my SLI gtx 670's only use 550watt for the entire system at the wall

long as it's a good brand psu you will be fine

I have a mini ITX office rig with a Silverstone SFX 450w supply.

It powers an i3 (35w), a GTX 570 (220w to 230w), and various fans, drives etc.

I will be changing to a 970 which will run at about 150w, saving me maybe 60 to 70w at max, so I would suggest that from experience a 970 will run very nice on a 450W supply, but does depend what else you will run on it.

deano-5 · 17 Mar 2015 at 03:58

My Silverstone SFX 450w is fine with a 280X and 4690k

Tute · 17 Mar 2015 at 10:03

450W here with a 3570K and GTX970. I think you'd be fine with any single GPU card, my previous one was a 290X. Still no issues.

ghost.florian · 17 Mar 2015 at 13:00

The rig in my signature does not draw more than 380W at full load. What are the specs of the rest of your system if I may ask ?
