Power related good product for M/B

Anyone knowledgeable in configuring correctly a product of power related stuffs, so can point a decent one?

What'd be suitable PSU for ~ 65 TDP CPU set in motherboard MSI H310m:

Find the PDF spec sheets for your motherboard and video card. Look for the watts used and add them together and add 20 watts for the rest of your setup.

My general rule of thumb is:

Max CPU power + max GPU power + 100W for the motherboard chipset + 10W per attached drive or device.

The round the result up to the next standard PSU rating.

Look for an "80+" rated type, as they are more efficient that non rated ones, they take less input power (so cheaper to run) for the same load rating, and produce less waste heat.

Would you please elaborate birefly the term "80+ rated PSU" preferably with concise logical and historical reasoning to be its popular say.. please, I'm really noob in M/B PSU

This webpage will tell you about the 80+ system of rating PC power supplies

It's the efficiency between the AC input power and DC output.

A lot of older or generic PSUs had quite low efficiency; eg. a 400W output one could be taking 600W or more at the AC side, and dumping all the excess as heat. That's expensive to run and bad for the computer cooling system.

The 80+ marking means a minimum efficiency of 80%.
A "bronze" grade one may be in the low 80s, while a "Gold" grade one should be well up in the 90% range.

For the same 400W output, if the PSU were 95% efficient, the input power would only be 421W at full load, just 21W of waste heat and excess power!
