Computer won't turn on after new PSU installation, please help.

[SylEm]

The Anandtech community has always been very helpful in the past, I'm hoping I can once again use your expert advice to help out my situation. My current build is below:

Current Build:
Intel Core i7-2600K Sandy Bridge 3.4GHz
ASUS P8Z68-V PRO LGA 1155 Intel Z68
8GB Patriot Gamer 2 Series 240-Pin DDR3 SDRAM DDR3 1600
EVGA GTX 580 SC 015-P3-1582-AR
128GB Crucial M4 CT128M4SSD2 2.5" SATA III MLC Internal Solid State Drive (SSD)
Corsair 1000watt PSU
COOLER MASTER Hyper 212 Plus RR-B10-212P-G1 "Heatpipe Direct Contact" Long Life Sleeve 120mm
COOLER MASTER HAF 932 Advanced RC-932-KKN5-GP Steel ATX Full Tower
22" Samsung LCD Monitor

I just purchased a Corsair HX1050 PSU last night and I installed it. After it was all plugged in, I plugged the power cable into the PSU and flipped the switch. The lights on the motherboard lit up (so far so good). I then went to press the power button on the computer to boot it up. When I pressed the power button there was a time "Click" noise that came from the back of the computer, I'm guessing near the PSU (I'm not referring to the click the button itself makes when you press it down), but then nothing turned on. The fans didn't spin, no sounds, nothing. The only thing giving me hope that the PSU was supplying power was the fact that the motherboard lights were on from when the PSU itself was switched on. Any ideas as to what's going on? I'm hoping its a simple issue of plugging something in incorrectly and not a faulty PSU.

Note: All hardware prior to installation was working fine, this was an upgrade, not a replacement for a bad prior PSU.


Thanks in advance!

Check a few things.

Is 20+4 plug good and tight?
Is the 4 pin power connector plugged in to the motherboard?
Is the CPU fan plugged in?
Sometimes the power supply has a plug that needs to be plugged into the motherboard fan header that controls the power supply or whatever.
Check the Video Card Power connections.
Check the drive power connections.
Check all the other connections.
Did the last power supply damage something?

Maybe there is a grounding problem. Sometimes the video card will sit not quite right pull it out and reseat it along with any other I/O cards. There is also a chance you nudged the cpu cooler and it is not sitting right and the CPU is overheating and shutting down.

Try using integrated video and see if that works. i.e. remove the video card and see if the BIOS displays anything. Also check BIOS settings.

Hey

If your 4/8 pin CPU power supply is not connected then the system won't start (or start for no more than half a second). If that's not the case, then try connecting the PSU to another system (don't remove it from the chasis, just redo the wiring). If it works there then it's most likely a mother board issue

Did you try putting the old PSU back in to see if the system still works as before? This will eliminate the possibility of any hardware issues that may have occured during the installation of the new PSU. If all still works that will tell you it's a problem with the HX 1050. You can pick up a PSU tester they're relatively cheap or use an ohms meter to check if each rail is putting out the correct voltage.

Besides the CPU connector, what other connectors could potentially cause the computer to not even power on?

The 20+4 pin connector is the only other one I am aware that would stop the pc posting unless.....

Not sure on this but maybe having a faulty 6pin or 8pin GPU connector might cause the same problem.

It could be the 6/8 pin GPU connector, but I can't be sure. The few times I have forgotten to connect the same I got a beep before the PC died, but the whole system got power before dying, i.e. all the fans, etc. started up.
