[SOLVED] GPU got fried. Should I replace my PSU

[jaimykoster2001]

So yesterday I was just playing Overwatch and out of nowhere my pc shuts off. There wasnt really a sign of anything outside that could've caused it (like lightning or something). When i tried to turn the system on all the lighting went on but my mobo gave a gpu error. Later i found out that it got fried but now im wondering how my gpu got fried and if i should replace my psu aswell. I can't test to see if the system still works because i don't have a spare gpu to trow in the system. All i had was another pc where i could try out the fried GPU (the gpu didn't work in that system aswell)

Also my psu always had a very silent hum even when the system was turned off. But i don't know for sure if its the psu that killed my graphics card

My specs are:
CPU: R5 2600
GPU: Sapphire Nitro RX 480
Mobo: MSI B450 tomahawk
PSU: Gigabyte B700H

What is the PSU that you have?

What is the PSU that you have?

I have the Gigabyte B700H psu (model nmbr GP-B700H)

 

[Ralston18]

How old is the existing Gigabyte B700H PSU?

Has it been heavily used for gaming, graphics, bit-mining, etc..?

Do you have a multi-meter and know how to use it? Or have a knowledgeable family member or friend who does?

I realize that with "social distancing" being able to get help is problematic.

However, installing another GPU as a test may only destroy that GPU as well.

Your CPU appears not to have integrated graphics - double check the specs to be sure.

If it does happen to have iGPU then you could use the motherboard's video ports.

Can always buy a cheap PSU tester as well.

A psu tester, like the paper clip test, can confirm a dead psu, but it can not test for proper operation.

A failed power supply is the prime suspect.
The only good way to test is to replace the psu with a known good psu.
A quality 550w psu is sufficient.
If you can't borrow one, buy a quality replacement from a shop with a good return policy.
Expect to pay a 15% restocking charge.

Of course, you are also going to need a new graphics card.
I don't think I would risk a new graphics card with the current psu.
The hum you hear sounds like trouble.

If the GPU went from the PSU, there is a good probability that the motherboard is fried as well.

Although i can't test it it does seem that the motherboard and cpu is still working acording to the diagnose led on my mobo. (It's only
saying that the graphics card isnt working)

You will want a 550W or 650W PSU. The biggest problem is that PSUs have gotten very expensive in the last few months and the stock that places have is low. Here are some suggestions:

550W 80+ Gold
https://pcpartpicker.com/product/gP...ed-semi-modular-atx-power-supply-focus-gm-550

Corsair RMx (2018) 550 W 80+ Gold Certified Fully Modular ATX Power Supply

pcpartpicker.com

https://pcpartpicker.com/product/sM...ed-fully-modular-atx-power-supply-220-g3-0550
The first one, Seasonic Focus GM, is the lowest quality of the 3 and is only Semi-Modular with a 7 year warranty. The other two, Corsair RMx & EVGA G3, are fully modular with 10 year warranties. Note that lowest quality doesn't mean bad here, it is already of higher quality than the Gigabyte B700H that you have.

650W+ 80+ Gold:

In this list there are a couple 750W PSUs since they are available whereas their 650W counterparts are either more expensive or on back-order until early June. This is probably the only time that I will ever have a Be Quiet PSU on a list of possible PSU choices because everything is so expensive. Most of the time you pay a huge premium to buy a Be Quiet PSU that doesn't perform as well as the cheaper competition.

I ordered a cooler master 550 watt 80+ gold fully modulair psu so i should be fine.

Er, possibly not. Cooler Master makes a lot of junk. What's the model of PSU? I'd be cancelling that and ordering a decent Seasonic or Corsair.
