HELP me prevent another explosion

[balmung11]

I'm using a case cooler master n600 , my psu cooler master v750w it suddenly died on me today it only last or 3 years for a gold psu idk what cause the issue i dont have a video card install on my pc right now then i change my psu to a thermaltake lightpower 700w within 3 hours that psu suddenly exploded luckily all my other components still fine by testing on my friend rig

idk what cause the explosion thing my v750 w cm does not explode but its not working , my stock from my old rig thermaltake explode

my current rig

ecs h61h2-mv v1 i5 3570 stock cooler g skill 8gb 2 fan 1 from the front 1 from the back 1 tb HDD generic AVR philips 15 inch led monitor

as you can see no video card no rgb no other components or peripherals that can get more power idk why my thermaltake exploded its a 700w even though its not bronze /seilver / gold / platinum psu i used that on my old rig for more than 5 years ,maybe it exploded because its old ? or my avr is generic ? if that is the cause why is that my cm v750w doesn't explode is because its a gold psu ??

need help guys !! before buying again a new psu

 

 

BTW Im going to upgrade my cpu/mobo soon + a new video card since I'm waiting for vega so i can decide if gtx 1070 or vega, thinking of a K chip or even ryzen cpu so i need a much better psu than before i hope it will last more than 3 years this time around .

btw i want a fully modular

what I'm eyeing right now with same price category

 

EVGA G2 650w corsair rm 650x seasonic x 650

Maybe the problem is in the wall outlet since it killed two different PSUs.

Get the Corsair or Seasonic, whichever is cheaper. It may be the wall outlet, try another one or a surge protector.

It could have been "dirty" power from the mains, old wiring in the walls where you live or a load drain by another electrical appliance drawing power inside your home, for example, an air conditioner/heater is running and the fridge/freezer turns on?

 

@balmung11 you could start by using a good quality two-way surge protector.

They are all good. Just buy the cheapest one.

wall outlet ehh well on my case my computer/electric fan/modem/speakers are the only thing connected to it 

on the mains yeah its old but we have a breaker ,fridge is always on air condition is off no heater since  l live in a tropical country 

ill get a power surge protector 1st since my generic avr is useless  

btw last week before my cm psu died i smelled something burning it might be my psu

The electric fan being plugged into the same wall socket even if it is a double outlet, and I understand the fan is an "essential bit of kit" (it is currently 36C / 96F here!) could provide enough of an electrical fade/drain over time that overstresses the PSU. My machine is 24/7 connected to a PSU which is the ONLY thing connected to that wall outlet.

A circuit breaker is a protection device that stops/cuts the power coming in from the street when there IS a grounding to earth, they are designed first and foremost to protect a human from dying (frying) from electrocution when they complete that circuit.

The two-way surge protector works as it sounds it protects from a spike in the power delivered from the wall but also if one of the devices on your power-bar draws too much current it disconnects the bar from the mains power. This can be useful to show if a device has an intermittent power draw problem. But a better power bar than this is one that has a property built-in that smooths out the delivery voltage from the mains feed. These are thought of as a "poor man's UPS" because they do not really add any effective relief to a clean energy supply due to the square type of waveform they create, as opposed to a smooth sinusoidal waveform (pure sinewave see diagram bottom). Also they only offer a relatively small backup battery inside which means they cannot really sustain a machine for more that just a few minutes after an outage.

This is the type of wear that can come from an electronic component that draws over and above the delivered current available from the mains supply, in a matter of milliseconds. You may not even be able to perceive this by eye until it lasts long enough to make an incandescent bulb light output dip momentarily! The component could include old wall wiring as when a device calls for energy the wire's poor conductivity adds to the issue.
