Will a 450 watt power supply be able to support gtx 750 ti?

[GreekTzatziki]

Hey guys. I am looking forwards to buy a new dedicated gpu since my current one is an integrated one. I decided to buy the evga gtx 750 ti sc but I am not sure if my power supply can support it. Sure it is 450 watts but since it is from a pre-built pc, it might be overestimated.
Any help would be appreciated.

Yes, 450W is plenty, even from a crappy supply.
The reference 750Ti needs around 60W while 3rd party cards could need up to around 90W or so.

Ok thank you very much

My pleasure

just put a 750 ti in my tower, and it works like a charm. no crashes, and it doesn't run super hot. Granted I have a fairly large case with high airflow, but I haven't felt air warmer than room temperature coming from it, even after 3 hours of SMITE.

Well, that card draws so little power even when pressed hard that it won't warm the air significantly.

Will it also be able to support the msi gtx 750 ti 2GB Oc gaming edition?

 

[Petrossa]

Yup, should have no trouble with that card either.

Yes, no trouble with that.

I also run an old PC with this exact card in it, it has only a 400 watt PSU - so you will be fine.

This particular MSI card pulls a theoretical max of 38.5 watts with its standard Bios.rom, even in 'OC' mode (using the MSI gaming app).

I modded the Bios.rom and now for example, it pulls around 70 watts* when the gpu clock is boosting to 1460Mhz and the vram at 3200MHz!

This card uses so little power it's unreal!
