Can 450W PSU power a Nvidia GT 730 1GB GDDR5?

shadowray95 · Jun 2, 2015

Hi i have 450W PSU from Intex. It say 18Amperes on 12V rail. Is it sufficient to power my gpu?

Processor- Intel i3 3rd Gen 3.3GHz
Ram- 2x4 GB DDR3
GPU- Nvidia GT 730 1GB GDDR5

Sure shadowray95. 450 watts is more than enough to run GT 730.

18A should be enough to run it.

HELL YEA IT CAN, my GTX 970 is being powered by an EVGA 400w psu with a 4690k

A cheap HEC 400W for a 970 + i5 setup?

You're teetering on the edge of PSU explosion and destroyed components right there buddy.

Well. That PSU although of a lower quality, would be more than enough.

But at a higher level of usage, it would be preferred to get a better PSU.

Like an Antec VP450P which is readyly available here in india in most online retailers for around Rs.2500.

is of a very good quality and has all high quality Japanese Capacitors.

It will be more than enough

I checked pc part picker and its only using 300w in total

A 970+i5 system will use about 300-350 watts, Your PSU is rated to supply 360 on the 12V+ rail.

You're cutting it close.

the i5 and the 970 come at stock speeds, the 970 is 1.05GHz and the i5 is at 3.5GHz. I going to be getting a new power supply next week because Im going to get a second 970, im going to get a 650w fully modular power supply from EVGA

Okay. If you are going for a PSU upgrade, don't limit it to 650Watts. go for a 750Watts if you are going to use an SLI setup. 650 watts will be enough for that specially if it is a very good quality PSU like an EVGA unit or Antec unit.

pc part picker says that my rig, when I add a second 970 will use 477w so I will have 173w left over with 650w, do u still think I should get a bigger psu?

kwa-e · Jun 26, 2015

I trnd to not trust the power calculator of PCPP as it calculate card TDP and not the actual load power consumption.

650w will allow for 970 SLI but you wont have much headroom to overclock.

750w on the other hand is all you will need

senseijtitus · Jun 26, 2015

750 would be a wise choice since it will eliminate any issue or a need to upgrade the PSU further in the future. 650 watts will also do. But 750 would make it even better.

GTX 970: maximum 290-320W at peak consumption. (depending of model)
i5 4690k: 100W at peak with slight overclock (around 4-4.4Ghz)

400W is just barely enough. Not to mention there is the other parts like motherboard, RAM and HDD taking power.
Also, the fans and cpu cooler.

You are probably maxing the psu out most of the time.

senseijtitus · Jun 26, 2015

Yes. And PSu would be stressed to the limit & that is not at all a good idea.

Matteo De Vellis · Jun 26, 2015

Sapphire Thunder :

Ok, will do, thx for feed back, I will get a 750w or maybe even bigger

senseijtitus · Jun 26, 2015

Matteo De Vellis :

Good. That will get rid of possible issues in the future. Happy building.

I just entered my system on the psu calculator website, and it says my whole computer will use 752w (with overclocks) so yea Im going to get an 850w

Good. Higher the better.
