Question PSU question

[Dave DAvis]

hello
I wanted to know if going from 400watt to 500W PSU have any affect on electricity bill increase

For example if i had 200watt worth of components running on both PSU will i see a difference

If they operate at the same efficiency then no, or at least so small you would never notice.

400W one is generic white box. While 500W is 80+ bronze. Same result?

Probably not. Assuming the 500w actually has a genuine 80+ bronze rating (cheap units sometimes lie) it should be more efficient than a generic no efficiency rating unit. I am generalising.

You'll save money, but it would probably be years before you saw savings that matched the price of the PSU.

Not that you shouldn't replace a junk PSU with a better one. If the better one actually is a better one; since you don't give information, it's hard to say.

I am planning on an upgrade but very vary about the electrical bills . So not sure if the bronze 80 plus actually helps in cutting that cost.


Going from
i5 3450 to i3 12100f
1050ti to rx 6600
Generic 400w to 500w bronze

Want to know how much of a marginal increase would i see

It won't help much.

Also, both of these PSUs are very cheaply made group-regulated PSUs of ancient design. Neither are appropriate for a rig with an RX 6600 and CPU platform newer than Haswell. Hopefully you have not made a purchase of one of them already.

A psu will use only the wattage demanded of it, regardless of the max capability. How much power is drawn from the wall is determined by, in part, the efficiency. Bronze 80+ is the usual starting point and going up.

Another factor is how loaded a psu is when operating.
The most efficient point is about the middle of the range.

Here is a handy chart to size a psu:

If you think a graphics card upgrade is in your future, over provision the psu up front.

You will not likely save any on electrical bills by buying a psu with a high efficiency rating.

Of most importance is the quality of your psu.
A cheap psu that fails can damage all of your other parts.
Not knowing anything else, you can estimate quality by looking at the warranty.
7 years or more should buy you a decent quality unit.

Its C tier in cultists, which is what im expecting for a budget build. Im also considering undervolting GPU to game on 60fps.
I'd welcome any suggestion from their site
