- Gigabyte B85 Motherboard
- 8GB Ram
- 128GB Adata SSD (for OS only)
- 1TB Western Digital HDD
- Nvidia Geforce GT-630 Graphics Card
- 22" AOC IPS Display Monitor

A 300W PSU would suffice as minimum (as recommended by Nvidia). http://www.geforce.com/hardware/desktop-gpus/geforce-gt-630/specifications

A GT-630 isn't really any stronger than your CPUs integrated graphics.

Just get any Power supply that isn't total garbage. For example, you should just get this

Cheap and effective.

Hello MajorMono, thanks a lot for your superb solutions. I'll just say wow! I'm going to the purchase
CORSAIR CX series CX430 430W 80 PLUS BRONZE Active PFC ATX12V & EPS12V Power Supply-500Watt. Thanks again.
Cheers.

You do know that the CX 430 (the green label version with CP-9020046 product code) are poor quality PSU's (i.e., garbage), with only 3-year warranty, only 30C rated operating temp, and 1x PCIE connector. It has already been discontinued and replaced by the more efficient, better-built, higher quality CXM (the grey label versions).

You should get the CX450M (gray sticker with CP-9020101 product code and NOT the CP-9020058 with the green sticker), 5-year warranty, 40C rated operating temp, and 2x PCIE connectors.

Yeah, you should go with that if you have the extra money to spend. the CX430 will suffice though for the time being, since you only seem to have a GT 630

Hello raisonjohn, thank you very much. Can you please provide me with details of CX450, or share a source link. So that, I can compare both of them & I can take a decision. Thanks again!

Here you go: https://www.newegg.com/Product/Product.aspx?Item=N82E16817139146&cm_re=CX_450m-_-17-139-146-_-Product

bit more expensive but better.

Or even better, this

The most reliable of the 3 and cheaper than the CX 450M if you don't want to wait 6 months for the rebate

Ehh, the CX450M is better still. 70w isn't much of a contender, the CX450M is semi-modular, newer, more versatile, better amperage.
