Solved PSU requirements for graphic cards

[nfsworldrace]

im planning to build a pc
i have a true rated 300watts psu, but hd 5450 needs atleast 400watts in psu. is it still ok to run the graphic card in that system i dont know about the amps.

other spec
pentium D 945
2gb ddr2 ram
intel mobo

I have to say no.

It "May" run for a while but the 300 Watt PSU will be under heavy strain and will most likely die at some point, it may wreck some of your other components along the way when it dies too.

In my opinion it is not worth the risk. I would recommend upgrading to the best branded PSU you can afford and higher than the 400 watts if possible, this will allow you the choice to get better graphics cards and components in the future should you wish.

The problem is, you have not filled out your system specs, so we don't know what PC or case you have. This is of importance regarding the PSU too as many OEM cases will not allow the fitment of regular sized PSU's.

Hope that helps a little.

I agree with Paul. The power supply recommendation is for your total system. Use a power supply calculator. Extreme Psu Calc I would get a 550 at the minimum, giving room for future upgrades.

ill think ill buy geforce 210 but i checked its psu recommended wattage is 250watts
so is it fine to run in my 300 watt true rated if i changed it to geforce 210

 

[nfsworldrace]

i also checked geforce 210 psu requirements must havge atleast 300watt psu, so my system can handle geforce 210?

Should be OK, you are aware the 210 is a very low end GPU, I mean most cpu's have better built in graphics than that by a fair way now. It's fine for websurfing and basic games but don't expect much from it. I owned one a long time back.

If you want to put ANY GPU in, you will need a new PSU. 300 Watts is just not enough - unless you want to set the house ablaze. And as was said, 550W is the minimum. I would even go with 650W from a reputable company like Antec.

It's fun to wrestle with the wires. Here is when I did it last.

Not wanting to start an argument, I also consider 300 watts to be too low for any modern GPU, but 550W is not needed as a minimum, there are some fantastic lower wattage PSU's available for lower end GPU's when a user is on a budget, for example the XFX Pro core edition 450 Watt or Corsair CX430 or Seasonic G-360 Watt.

In certain circumstances with lower end GPU's these PSU's will do the job and do the job well.

As I mentioned before I would recommend going higher than he needs for the purpose of future upgrades, but the point I am getting at is he does not need 550 Watt as a minimum based on the GPU he listed in his OP.

I get the feeling he does not want to upgrade his PSU so all of this is pointless. Of course my recommendation would be to upgrade the PSU first, but it's up to him if he wants to take the risk.

Dang I gotta start spreading some rep. I can't rep either of you guys as I've not spread enough around.


Anyway really nice post

im not planning this to upgrade any more with pentium D and geforce 210 im happy with it, im saving money for better build maybe after a year, this pc is only temporary for me to play online games without setting max graphics (im not a hardcore gamer just a casual one). so im asking if i could atleast run this components without having issue after all i got a true rated 300watt psu ang the minimum i checked is 200 but recomended is 250.

 

[nfsworldrace]

no im not planning this to upgrade any more with pentium D and geforce 210 im happy with it. im not a hardcore gamer just a casual, playing online games not at high/max settings. will it run without a problem

It's kind of like asking how long a car engine will last for when you are running it at 5000+RPM constantly, it may last a while it may not, depends who built the engine. What brand is your PSU? I get a feeling it is not a quality branded one.

I know you are on a budget but I don't want to be responsible for you wrecking your PC.

Nobody on here can say if it will run without a problem, you have been advised to get a better PSU and that is that. If you don't want to then the risk is on your shoulders my friend.

The spec for that GPU is 300W total, not 400 W, don't know where you got that. That includes the CPU etc. The maximum total design power for that card is about 20 watts. Add to that about 180 watts maximum for the rest of your system and you fall way below 300W.

You will be fine with that PSU and graphics card as long as it actually provides 300W with no issues.

 

[RoasterMen]

Are you kidding me? the HD 5450 does not even consume more than 30w at full load, 300w is more than enough except if you upgrade to HD 5670.

My old PC that had HD 5450 with 250w ran fine

i think my psu is made of big factory manufacturers its not custom made. my pc brand is DELL with pentium D procie and 2gb ram 80gb hdd etc and adding my geforce 210.
