Hi Etr98,

Let me know the system model.

If the motherboard has stopped working third time, I would suggest you to try a different PSU and ensure that all the fans are working properly.

System board is suppose to be replaced by a professional only.

Did you perform any hardware upgrade on the system(Video Card, memory or hard drive).

Thanks & Regards

✔ Best Answer
If you're buying cheap junk PSUs, that's likely the problem. Please post your system specs in detail along with the make/model/wattage & specs of the PSU (or PSUs).

Here's what to look for when shopping for a PSU:

- wattage - generally at least 400W, more may be required depending on the hardware configuration
- single +12v rail with amperage of at least 30A, higher is generally better
- +3.3v & +5v rail amperage should be roughly 20-25A, if it's significantly higher, you should question the quality of the PSU or it's design
- active PFC (power factor correction), NOT passive
- 80 PLUS Certified - this means the PSU is at least 80% efficient. There are different levels - bronze, silver, gold, etc
- proper type & number of connectors depending on your needs (24-pin or 20+4-pin main ATX, 4-pin ATX12V or 8-pin EPS12V, SATA, 6-pin PCIe, 4-pin peripheral, etc)
- reputable name brand - Antec, Corsair, OCZ, Rosewill, Seasonic, Silverstone, Thermaltake, XFX, to name some of the top brands
- 3 yr warranty or better

This 430W Corsair unit is a forum favorite & highly recommended: CORSAIR Builder Series CX430

"PSU silverpower 500w"

Never heard of it before but Tom's Hardware gave the SP-SS500 a pretty decent review. You didn't mention any of the other brands you've tried but it appears the Silver Power SP-SS500 is a good one if that's the model you have?

Now post the make AND model number of the other PSUs that you've tried.

Hi Etr98,

Motherboard failure can occur due to numerous reasons. It can be caused due to any hardware installed on the system. It seems like the configuration you have on the system might not be compatible and that is the reason motherboard is failing. It would be better if you check the system with a different PSU first and then move on to graphic card. Also, let us know if you replaced the motherboard with a different model or it is the same replacement.

Sapphire HD 7870 is a decent GPU and it requires 500W PSU. Try more powerful PSU to isolate the issue.

Thanks & Regards

Motherboard failure isn't all that common so 3 boards going bad means something isn't right. It might be the power supply or you might be doing something wrong during the builds. How did you determine all 3 boards are bad? Did you bench test them?

Adding to #7 above:
Have you made sure you have all motherboard stand offs in the proper place with none missing and no extra ones under the motherboard, plus screws in all of them from the top of the motherboard?
Are you properly installing the CPU heat sink with a clean CPU and heat sink and the proper application of thermal compound? Follow these directions for your CPU:
Are all connectors properly plugged in?
Do you have your CPU heat sink fan plugged into the CPU_FAN connector? some motherboards will not start if it is not plugged in here.
Are you sure your motherboard(s) support your CPU selection? With your BIOS version?
Most other assembly issues can be discovered by proper bench testing:
Post results as well as exact makes and model numbers of components.

You have to be a little bit crazy to keep you from going insane.
