I ordered these parts for a low budget no gaming build.

Corsair CX430 Builders Series $39.99 - $19.99 after rebate- mixed reviews and I knew better than to cheap out on the PSU but it's a Corsair so......

ASRock 880GM-LE AM3 880G MB $59.99
AMD Athlon II X3 450 Rana CPU $79.99
Patriot 4GB (2 x 2GB) 1333 RAM $39.99
SAMSUNG Spinpoint F3 500 GB $49.99
Rosewill R101 Case $29.99
Keyboard and Mouse $29.99
Acer X223WDbd 22" Monitor $139.99
ASUS DVD Burner $18.99
Windows 7 $99.99
ALTEC Speaker System $19.99


Subtotal: $633.89



Hooked everything up, flipped the switch and no fan movement, a very slight high pitch whine from PSU, CPU cooler didn't spin, nothing happened.

Checked voltage on one of the extra molex connectors, 0v on both the 5v and the 12v pins.

On 24 pin connector - shorted pins 15 & 16 and the PSU fan started spinning.

On 24 pin connector every pin shows 0v with 2 exceptions.

Ground to pin 9 ( standby power ) has 5v

Ground to 16 ( power supply on ) has 2v



Any ideas ?

All I know to do now is order another PSU. Better quality this time.

Solution
When you shorted pin 15 to 16 to jump start the unit did you have a load on the unit like a fan on a molex connector? Some units wont output power in a zero load situation, if you hook up a fan to the molex connector and it spins up that will tell you the 12V rail is pumping power.

Thanks for the responses.everyone.

I tried several things, including a known good fan.

I ordered a Antec BP550 Plus. Connected everything and it fired right up. System is snappy for spinning HD.

I've built 10 systems and used Seasonic or Antec PSU's in every one except this low budget build. Corsair may want to rethink the CX430.

I thought I'd try to keep the budget down, wrong decision in this case.

$40 lesson learned. ( unless I get the $20 ) Corsair rebate.

All is well now, I kept it running several days and it tested out fine.

Shipped the system to it's final home yesterday. Time to clean up my work bench.
