Windows 7: New Computer not powering on,is it because of not powerful enough PSU?

New build not powering on, Any Suggestions why?

So today I bought my self parts to build a new computer for my parents, here are the parts:
A10-5800K
Gigabyte F2A85XM-D3H
Cooler master elite 342
Kingston 4GB DDR3-1600
Western Digital 1 TB blue Sata3
And the power supply im not sure but its a 420W PSU that came with the case, I think its quite low quality but as it came with the case i thought i would just go with it

So when I assembled everything, it didn't start up and the lights just flickered, Then I Connected the Power + and Power - pins together with a screwdriver and the CPU make kind of quiet clunking noises and the PSU fan spun for a brief sec.

Is this caused by not having a PSU powerful enough or is this probably some other reason? though a online wattage calculator says i only 240W for this system :/

If its the PSU Im thinking of getting a Cooler Master GX 550W 80+ Bronze

My bet is that the PSU is the culprit because the PSUs that come with these cases are utter crap. I apologize for the way I said that, but I don't know of any other way of saying it right now.

The Cooler Master GX Bronze Series units aren't bad; they're not great, but they're actually somewhat decent. Of course, you can do better than the 550W GX Bronze Series.

This is a stupid thing to do, never do it again. You are risking your own life and/or to fry your hardware.

Other than checking again your cabling and that you did not screw up with jumpers and whatnot (check the motherboard manual), I tend to agree with the guy above. You probably got a crappy PSU in that case.

As far as PSUs anything that has the 80+ certification is fine. It means that they are tested and can reach and keep 100% of their stated capacity without dying horribly. For a general-use PC you don't need more than that.

As long as the PSU is working, it should be more than enough for that system.

I hope that you meant that you bridged the pins on the front panel header. (That's a legitimate way of checking for a defective case power button.)

Did you connect the 8 pin (probably 4+4 pin) 12V CPU power connector? (Just guessing at random here.)

Hum pity I didn't see this before this is what you should have had a look at first mate http://www.sevenforums.com/vip/257690-psu-how-test.html#post2130086

Using screwdrivers like that well again very reckless and as Twp Cables says the generic struff is crap. Fra better off witha a few extra dollars and get a good one.

I like Corsairs personally and this might have ben a good buy for you Corsair CX-750 V3 Power Supply [CMPSU-750CXv3] - $109.00 : PC Case Gear

or better still Corsair HX-650 V2 80 PLUS Gold Power Supply [CMPSU-650HXv2] - $139.00 : PC Case Gear

As AddRam has asked I hope these were the right way round - I don't know what the actual consequences of reverse polarity would have been on a mobo but I have destroyed many devices and dedicated components in the past by doing that - even briefly.

I'm sorry, but this is not true. There are 80+ Certified PSUs that are utter garbage and should be avoided.
