Can the power supply affect the speed of the computer?

Question

System administration

Good afternoon, I recently purchased a new motherboard asrock pro 4 h270 chipset and a 6th generation intel core i3 3.7 GHz processor, the power supply remained old, weak at 230 watts. The computer works but slows down. worse than my old dual core. changed 3 hard drives. it doesn't get better. put both 10 and 7.

Answer 1

For stability, yes. For performance, no.
From the power supply there is no feedback of the type "I can not give so much power, limit the load"

Answer 2

Windows has very specific performance monitoring tools. If there is a dozen - press Ctrl + Shift + Esc and go to the "Performance" tab. We look at what is overloaded at the time of the occurrence of "brakes". Wangyu that there will be 100% HDD loading (with a demonstration of "inhuman" throughput in the region of a couple of MB / sec) as a result of a swap due to lack of RAM, a crappy SATA cable, or the poor condition of all three tested drives that were taken from a dusty cabinet)

Answer 3

The processor may not be getting enough power.

Answer 4

No.
If the power supply is weak and does not provide high-quality power, problems begin, such as unstable operation, crashes, blue screen freezes, shutdowns, disks can quickly fail, etc.
But the speed of work does not change in any way.

And how much memory do you have and what disk is under the system?
In order for the computer not to slow down, two conditions must be met -
As a rule, the brakes are a lack of memory and / or a slow HDD.
This is especially complicated if the HDD is faulty, there will be generally unrealistic brakes.

Answer 5

What is the rest of the kit? Voltage on the 12v line?
If the voltage is below 11.5 volts, the power supply either cannot cope, or it is already bad for him.
