Is a 450 watt psu enough for a msi gtx 750 ti 2gb Oc?

GreekTzatziki · Apr 23, 2016

Hey guys.I want to upgrade my video card and I think I'm going to buy the msi gtx 750 ti 2gb Oc gaming edition but I don't know if my power supply will support it. Unfortunately it is a 450 Watt crappy no brand psu from a pre-built pc. I went to the psu calculator and with the gpu the system max watt usage was only 210~230 watts. I am not pretty sure what to do.
Any help would be appreciated.

It's enough for power requirement. However a low quality PSU is never recommended.

Some prebuilts have ok-ish psus. Do you know the model?

unreal9400 · Apr 23, 2016

It's more than enough.

PSU calculators are known as random number generators.

All we can do is speculate. I think it'll be fine. There should be a model on the PSU. Can you tell us it? Or take an image and post it here?

He said "crappy no brand psu"

Once someone called seasonic a generic no name brand because they've never heard of it. Never assume. Even getting the prebuilt model number may get more info or even a pic of the psu label to get the ul number to trace manufacturer.

I can't find any model name or brand.I have taken a picture of it but I am a noob and I don't know how to post it.

usually oem(acer/dell/hp/etc.) brands use more reliable units than cyberpower/ibuypower/etc. when it comes to sub 500w power supplies. otherwise a 450w unit is plenty for a 750ti which cant really draw much more than 75w. though evga has some no pcie pin gtx950s now that can also be used in place of 75w 750tis.

Upload it on postimage.org then post the link here.

Prebuilt companies like Dell and HP can't use extremely hazardous PSUs because just think of all the suing that would occur and mass media frenzy when people in this world would start saying "Dell and HP computers blow up!" Look at hover boards.

Here's the psu (sorry for the quality) :http://postimg.org/image/4nkm5p73r/

From what I can find, it's manufactured by Deer.

We can't really be sure if it'll be fine or not. All you can do is plug it in and try. It'll probably be okay.

k1114 · Apr 24, 2016

I'd say you want to stay away from deer's fireworks but if you really can't help it, it should be enough power.

GreekTzatziki :

That's a 60 Watt video card! With all power supply questions always list all your hardware.
But in general it will do just fine.

unreal9400 · Apr 24, 2016

GreekTzatziki :

That's a total of 30A on 12V+ rail.
More than enough to power the system and graphic card.

turkey3_scratch · Apr 24, 2016

unreal9400 :

Not all power supplies can meet their rated amperage while maintaining stable voltages or without other troubles arising. Not only is labelled wattage unimportant, but the amperage rating is not too important either when there is a good chance it can't be fulfilled.

GreekTzatziki · Apr 25, 2016

The msi model I want to by needs 400 watts minimum, 100 more than the reference card. I don't really know what to do guys.

unreal9400 · Apr 25, 2016

GreekTzatziki :

Worst thing that could happen is the power supply won't turn on if there is not enough power or PC will shut down itself if there is not enough power.
Anyway what is the rest of the system specification?

Deer Computer Co. Ltd. isalso known under other brand names like:

Apex Computer Technology, Inc
Austin
L&C Power
Solytech
Supercase/Allied

All bad OEMs and companies. Deer PSUs are Tier 5, Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.

Deer PSU review where the past reputation of Deer is expounded on. It blew up in the review.

Please get a better PSU that is Tier 1 or Tier 2.

Pc specs are :
Amd athlon II x3 455
4gb of ram
Integrated ati radeon 4250
450 watt psu
I don't remember the motherboard model but it has a pci-e slot

I have this pc for like 4 years and I hadn't had any problems with the psu. I just want to know if I should buy the gpu. The cpu is old and I don't think it draws too much power so am I good to go?

Alan Caldwell · Apr 25, 2016

That processor has a TDP of 95w. Get a better PSU.

GreekTzatziki · Apr 25, 2016

Ok guys, everybody is giving me different answers, Please just tell me if I should by the card because I don't want to upgrade my psu...
