Power Supply Recommendation?

[PhilipDM42]

I've tried checking the forums and Neweggs recommendation checker, but still not an exact answer.

I have:

DeepCool Tesseract Case with 2 Led Fans
GTX 1050 ti
i3-7100
Gigabyte B250M-DS3H MOBO
2 8GB DDR4 2400MHZ
and as far as Hard Drive, I'll be buying one from best buy 1tb, not sure of the specs.

I need to know whether I'll be overshooting the necessary wattage because the only Power supply on hand at my nearest best buy is 750W. I know I should go for 500W, but maybe I don't because CoolerMaster over here is telling me 300W is sufficient.

To receive the right answer, please give detailed information as to how you came up with the answer. Most of the other threads just throw out a number. I'm hoping this thread will help others whenever the search the same question.

The build won't even top 230w , but your better power supplies start a 450w , here's a great deal.

you need a good 450 , psu.

quality matters , not the wattage.
I would even good for a quality 550w psu, may you ever upgrade in the future.

now what do you think of this?

I would upgrade, but that'll be in a year or so. I'll go with the 450 from the Senior Moderator

Please give details as to how you guys came up with those numbers too <3.

Personally i dont recommand lower than 450 Watt, because of the lack of connectors you will need perhaps in the future

7100 .......51W
Motherboard....60W
Memory Modules .....11W
Caviar Blue 1TB ........20W
1050 Ti Video Card.........75W
Fans ....1W - 5W
Fans ...1W - 5W
Total if all were maxed which won't happen ......about 227W-230W , PROBABLY a little less

Cool, thank you.

Question:

I'm currently on a prebuilt PC that is using 250W power supply. I already placed an order on the 450W, but I would like to test my pc.....now. Would you allow someone to use an old Power supply and connect it to the custom built PC?

 

[Dark Lord of Tech]

No I wouldn't risk it , newer power supplies have better built in protections.

KK Thank you, will have to wait then.......unless Best Buy offers Guarantee returns to 750W power supplies with receipts
