Help

I removed my 1 week used corsair CX430 CWT built thinking its low quality as suggested by exparts here cheap samaxon caps etc. it was powering my 3770k and gtx 670 fine !

I just bought a Antec HCG620 Seasonic built japanease caps good quality psu as exparts persuaded me here BUT......

when I finished installing as soon as i on the psu switch on the back, I saw little spark came out from the mash grill and my kill a watt showed the psu pulled 30 watts fraction of a sec and then went down to 1.9 watt
Now immediately i switched off the psu and TOO scared now to on it or turn on pc.

Is it normal ?

The psu cost me £75 from local shop doubble to the corsair cx430 so i need some exparts suggestion here.

HELP !!!

You don't need to move cables, just unplug them.

A brief spike in power from the wall, when the PSU is first turned on, would be fine. The fan probably spun a bit at that point, and the +5VSB circuit charged. A PSU, when plugged in and powered on, is never fully off. It has to be ready to power the standby rail and come on quickly when main power is requested.

What you are describing typically happens for one of two reasons - first is something isn't connected right. Second would be that your power switch (110/220V) isn't in the right position.

It could be moisture in the PSU as well (condensation), but that is far less likely.

Last thing it could be a defective PSU.

It might have been something very minor, like some material left over from the assembly or something that fell in there.

Disconnect the PSU completely from all of your parts, and make sure it is off.

Use a paper clip to bridge the green wire and any black wire in the 24-pin connector. Then turn it on.

Paper clip PSU test

Try that a few times and if there's no further issues you are probably safe enough.

Theres no such power switch (110/220V)
it has only 1 switch on/off
if i turn on again will it burn damage my pc?
i checked all connection all ok no visible flaw, everything ready, just need to switch on the psu and then switch on pc

is it even safe to switch on now?





im thinking why it showed half a sec 30 watts pull at first and then idle 1.9w?

isnt it meant to do less than 1w @ sleep/standby?

is there any other way can i test the psu without taking it off from pc?
i spent hours in cablemanagement everything now would be pain to take it off again

Help !

Yes
If it doesn't they will replace it.
Your max power is always much higher than gaming power usage. If you worked at it, with an overclocked CPU and GPU you might get close to 400W from the wall. Gaming, you will never get much over 300W. You probably did need to upgrade, and you cannot predict what your power usage will be in 5 years.

I have purchased many PSUs in the past, the better brand name/models will last longer overall as compared to non-branded or models that are manufactured by others. I always buy Antec, Seasonic or Corsair...the price is about 25-50% higher than the no-brand....but worth it for peace of mind. The Corsair CX430 is a power supply I have used in many builds...

There is an online wattage calculator at: http://www.extreme.outervision.com/psucalculatorlite.jsp

I use this to determine what PSU to buy for my builds. I usually go about 20-25% higher, so if it recommends a 500W PSU, I will get a 600W-650W to be safe (you never know when you will add a HDD, USB devices, etc).

One thing about the better power supplies like you bought - they have good power regulation, and if you had a short, the PSU cuts out quickly preventing damage to components. Both of your PSUs are in my opinion good....
