Two PSUs broke on me. How do i stop them from breaking?

Som3thingElse · Aug 13, 2016

I had a cheap PSU break a couple months ago (thankfully it didnt destroy anything). I then borrowed a friend's old PSU (SCANFX own brand) and that exploded a couple days ago. Both broke while while playing games so the PC was under alot of load, could that and the fact that the PSUs are cheap have caused it, or is it something else. My friend had been using the PSU for a while before he gave it to me and I thought it was odd that they broke so soon after I got it. What should I do to stop this from happening again, apart from buying a good PSU, which I will be doing.

Specs:
Motherboard: Gigabyte 970a-ud3p
CPU: FX-6300
Ram: G-Skill - F3-1600C11S-8GNT

Didn't mention your first one but second one is a pos.buy a better supply http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html no gaming rig should be below tier 2 if you have lage drawing components

2 broke PSUs = don't buy or use cheap PSUs.

Well running a cheap unbranded, or not very trust worthy power supply is wise.

I see you have posted some of the specs of your system.
How ever you have not included what graphics card you are using if it is a Pci-e based card.
You should post the brand of the card Nvidia, or Ati, and what model number of the card it is you are using.

If both the power supply`s happened to blow when using the system and playing a game with a Pci-e graphics card fitted to it, it will happen because the power supply used was a very low wattage unit or the amps quoted for the 12v power rails of the psu were very low indeed.

And the power supply became overloaded due to the amount of watts and amps a high end pci-e graphics card requires when playing a game.

Every card you buy has a maximum wattage rating, and will also tell you the maximum amount of amps that will be drawn from the power supply when the graphics card, and the gpu chip on it is put under a heavy gaming load Som3thingElse.

So you really do need to post the brand name of the graphics card you are using and it`s model number.
That is a must, then you can work out along with the rest of the parts of your system what power supply will be enough in wattage and amp out put you require. So the power supply does not explode again.

Oh my bad. I have a zotac gtx 750 ti, so it doesn't require alot of power. I have 2 7200rpm hdds and 3 fans. I just purchased a corsair cs450m, is that enough on the 12v rail?

Still an iffy quality one but probably a good bit better than the two you blew up. Should run your system.

OK thanks for all the help. Just to be extra safe is there anything else that could cause a power supply to break (like a problem with the mains or something) because my friend was running a similar system (almost identical and should have been drawing the same amount of power) and it didn't explode? Or was it just that the PSU detioriated while he used it, then broke on me because its cheap?
