Hi all,

I currently have a problem with my pc resetting when i play certain games which are quite heavy for my PC.

after some searching it seems like my powersupply needs to be replaced whoever i am not sure which one i need to replace it with.

I currently have:
Power supply: LPW12-23E 3*SATA 420 W
Motherboard: (MSI) MS-7994 Ver 1.2


Like you might already noticed from the question i have no idea where i can find the needed information so if i need to add more information could you also add where i can find said information.

Thanks in advance!
 
replacing the PSU would be a good thing, after that you could consider updating the BIOS and GPU drivers

check windows integrity
open the command prompt as administrator and type DISM /Online /Cleanup-Image /RestoreHealth

clean boot

check the memory by running memtest.org usb autoinstaller (bootable USB flash drive)

check the hard drives for errors with the manufacturer´s tool

use ddu uninstaller and reinstall the latest graphics driver

This one?
This is absolute crap PSU. 204W on 12V rail. It's basically 200W PSU.
Not suitable for being used with discrete graphics card. Replace asap.
GTX 950 minimum PSU recommendation is 350W.

Your psu does not have the requisite 6 pin power cable for a GTX950 card.
Using an adapter is dangerous.
If a psu does not have the requisite power cable, it does not have the ability to support one.
If your psu should fail under load, it can damage all it is connected to.
Consider a quality power supply as a long term investment.
Buy only a quality unit with sufficient reserve power to support a stronger graphics card. I might suggest 550-650w.
Here is a chart as to what differing graphics cards need:

Here is one list of psu quality tiers:
Look for tier 1/2, no worse than 3.

The one SkynetRising postsed is the one currently in the system. I bought it a couple years back in a prebuild case.

Just one more question, how do i know how many rails my power supply needs?

Acording to the chart is need atleast 380W with 6 pins (GeForce GTX 950).

If at all possible could you suggest one for me?

Thanks in advance
