Hello!

Let me start off first by saying I’m in no way a computer person and infact this is my first “expensive” pc as before all the ones I had were cheap small ones from currys so I’ve very little idea about what parts are good and so on.

Because of this I bought a prebuilt PC in hopes of being able to run games a bit easier (nothing fancy just aiming to not play on lowest graphics possible) but I’m having major issues with my power supply.

I sent the PC back to overclockers in October due to the PSU blowing and had them look at it and replace said part, it was returned to me the 15th of November and I turned it on for the first time on the 18th to update anything needing updated and logging into stuff like discord again before shutting it down

Today (20th of November) i turned it on again only for it to pop and let off a huge spark - PSU had blown again

Is there anything I can do apart from fight with overclockers again to try to get a higher quality one?? I genuinely didn’t do anything during the single time I turned it on to warrant the one overclockers had put in to blow again so its quite frustrating.

I’ve attached the pc specs that were on my invoice below if that helps for anyone since I’m not the best with computers haha

You had two blow in 2 months? Wow, that's unlucky. You sure your house power is alright?

As you suggested, I'd ask them for an upgrade, in the circumstances.

Its the only thing thats blowing anything else in the house (even another pc) has been completely fine so it has me quite confused this time we replaced the wires too in case it was something with the cables and still no luck :/

Or there is a component shorting?

Think its worth asking overclockers to do a full health check of the pc? Is that even an option? Last time they had me state what i thought was wrong for them to look at it but if its something I’m not sure about I wonder if I can ask for it all to be checked haha

definitely

basically its house electricity -> psu -> internal components
if it's a surge from your house leccy then other devices should also be affected/circuit breaker tripped
2x bad PSUs is incredibly rare (ofc never say never)
the last thing is your internal computer components causing a trip and the psu blowing up to save your computer innards

Okay that makes a lot of sense since nothing else in the house has been effected I’m going to assume the PSU is actually trying to protect the PC, I’ll message in to get a full health check of components and hopefully find what the issue is

Thank you for your help Tamzzy!! Fingers crossed we find whats wrong and don’t make it three blown power supplies

If the PSUs are coming out of their build stock (would imagine they're not hugely popular for DIYs) it's possible they had the same batch/fault. Though, I'd imagine OCUK would have more than just one PC with a problem, in that case :o

yeah its the kolink core in OP's build
whilst terrible, i've not heard anything bad (exploding) yet about them
and to be fair, a 10100 + 6500 build sips like 150-200w max load
the core 700 should supply 576w on the 12v continuous so that psu should be able to handle it methinks

:cry:
 
Did you plug it in same socket each time?
Wall socket not an extension?
Maybe you should get a surge protector on that socket

Anything you can do
Ask for a new tower unit?
They repaired it once and it blew again
If they put same type psu in there it's likely to do it again
Has to be a point it's irreparable and should be replaced

Or offer to pay a little extra and get a seasonic put in it
Though given what you already went through
I would look not to be paying for a psu upgrade as a goodwill gesture
I have a 10 year old ax860i here and would have more confidence in it
Than what they put in yours
 
It will be because of the abysmal Kolink Core series psu. They have the cheapest of the cheap internals and are based on a ancient design which is one reason that a so called 700w psu can only deliver 576w on the 12v rail. They are garbage and you should ask for a quality replacement.

And that misleading model numbering makes also honesty of those other numbers suspect.
Also as bonus QC&factory testing is likely minimal for these cheapos.
