PSU size for computer

[flamethower]

Im rebuilding a computer I have and I need to know how big of a PSU I will need.
Planning on the following items:
DVD rom
750 gb harddrive
160 gb harddrive
350 gb harddrive
160gb harddrive
2gb video card pci e
dual core cpu I5 2nd or 3rd gen
motherboard DH67BL
8 gigs of ddr 3 mem.
3 case fans 80mm
I will be loading 3 different OSs on 3 of the drives all 64 bit. XP, WIN 7 , WIN 10 One drive will be a share drive. I have programs that need different OSs and this computer is for that. I tried other methods but they don't work.

For doing the multi OS, you could have partitioned one drive, but if you've got a lot of drives and don't mind using them all, one OS per drive works. But to choose a PSU, we need to know all of the components, not just "2gb video card" but full model. To find out what hardware you got, you can use these two programs: CPU-Z (http://www.cpuid.com/softwares/cpu-z.html) and GPU-Z (https://www.techpowerup.com/gpuz/). Run each, it will tell you what GPU and CPU you have in detail.

Ya tell us what card you have. Most likely you won't need more than a good 400W PSU (or even less but there really aren't any less for consumers).

A 200W PSU should work. If only there were those what is your country and budget?

And what CPU?

dual core cpu I5 2nd or 3rd gen. usa can put up to 50 dollars us for the psu

[strike]Do you do rebates? http://www.newegg.com/Product/Product.aspx?Item=N82E16817139146[/strike]

There is also this, which is not as good as the above power supply but has an initial cost below $50 (with the $4 off promo code) http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028&ignorebbr=1

Oh, looks like the CX550M is $50 after promo code and still has a $20 rebate - you are lucky it's Black Friday http://www.newegg.com/Product/Product.aspx?Item=N82E16817139147&ignorebbr=1 - so get the CX550M.
