Spark and pop after installing new PSU?

Question

I bought a new OCZ 700w PSU for my PC so that I can use my new 8800GTS and upgrade in the future...

Today everything arrived, and I installed the OCZ psu... I was puzzled because the 24 pin connector is split to 2 connectors. The 20pin and the 4 pin... Oh well I said, and plugged in both. (bizarre)

Then I noticed that there's no 3 pin connector for the fan. There's only a 4 pin connector.
I plugged the 4 pin in to 3 pin. Then I connected the HD and DVD drive. Finally I plugged in the 2nd fan from my case and another 4 pin connector on the mobo.

I decided to see if everything works before I put in the g80... I crossed my fingers and turned on the power when.. BANG! I heared a loud pop and saw sparks flying. I thought I was gonna have a stroke right there on the spot...

I sniffed the PC.. No burning smell....


I crossed my fingers and plugged it in and turned on again... To my great surprise everything works perfectly! What could it be?

Here is my current system setup before any upgrades:

AMD Athlon 64 3200+ Winchester @ 2.3GHz
DFI Lanparty Ultra-D
1gig Corsair Value Select PC3200 DDR400 CL2.5
120gig HD
GeForce 6600GT 128mb
Sound Blaster Audigy 2 ZS
Antec Super Lanboy Case
Thermaltake Purepower 420W
Win XP Pro

Answer 1

The power supply cable is split into two connectors so that it is compatible with both a 20-pin and a 24-pin motherboard power connector. Some motherboards split the 20 and the 4-pin into two different plugs as well. If your board has a 24-pin, then you plug the 20 and 4 pin next to each other to fit in a 24-pin motherboard connector. It should be keyed to only fit one way so if it doesn't work, don't force it.

If the fan connector has 3-pins and the plug onboard for it has 4, then you might want to get a 4-pin connector for it. The wiring layout may not match the right voltage streams from the motherboard and the what the fan is designed to use if the pinholes are not using the correct plugs. It might work, but you also might be taking a chance on that.

Additional note: OK. As it turns out, they are indeed compatible.

You should be OK as long as the wire colors (should be yellow, red, and black) match the numbers on the pins.

possibly its out of your ability button itself, if thats the place you observed the pop. swap works by ability of connecting (2 conductor touching) and disconnecting (no longer touching), so once you ability on or off a swap, there's a element the place the swap is close adequate yet no longer touching yet. This creates a phenomena commonplace as arcing, the place electric powered fee jumps in the process, becoming sparks. for this reason once you turn off a useful speaker, you frequently pay attention the speaker producing a noisy pop sound. arcing reason a spike of present day into the speaker. besides, laptop works on very low watt, so any electric powered leak will consequence in a pointy soreness on your finger, yet you heavily isn't killed. It happens to me many circumstances in the previous. in case you experience such leakage, then its in all risk a bad ability supply leaking present day out. Oh, and um, just to your information, while a powersupply is going POP, it is not a capacitor. it must be the flexibility transistor too. merely so which you be attentive to... of direction if such transistor have been given burned out, your laptop won't paintings anymore.
