Self build

Hello Experts Exchange,

I decided to finally build my own home server.  I have put together a couple home systems before and had also read an article suggesting a recommended build so I thought I would try it.  I assembled all of the parts but now whenever I attempt to turn it on all of the fans light up and start for about two seconds and then everything turns off.  If I let it sit it will do the same thing in about 5 seconds.  This loop continues until I pull the power.

I have checked/re-seated all of the cables, reseated the processor, cpu fan, memory and also the motherboard with the same result.  I have also tried a differnt power supply (700W) but still the exact same result.  I have also ensured both the 24 pin and 4 pin power cables are connected to the motherboard.

Without buying more components to swap out I am unsure what the issue may be.  I have not added a CD/DVD Burner, video card or any other periphials as of yet.

I have the following components:

LIAN LI PC-Q08B Black Aluminum Mini-ITX Tower Computer Case (Model PC-Q08B)
Zotac H55ITX-C-E LGA 1156 Intel H55 HDMI USB 3.0 Mini ITX Intel Mobo (Model H55ITX-C-E)
Seasonic SS-460FL Active PFC F3, 460W Fanless ATX12V 80Plus Gold Certified PS (Model SS-460FL Active PFC)
Recertified Intel Core i3-530 Clarkdale 2.93 GHz LGA 1156 73W Dual-Core Processor Intel HD Graphics (Model SLBLR)
Crucial Ballistix Tracer 2GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) (Model BL25664TB1337)

If any experts have any ideas please let me know anything I may have missed.  All parts are new except for the recertified processor.

This behavior (short power-ups) usually indicate a PSU problem, however I can see that you have tried swapping it out only to produce the same result.
Does the power-ok light go on on the motherboard? (it's a redundant question really).
Do you have a multimeter handy? Do you have a powersupply tester handy? On some motherboards there is more than one 4-pin connector.
Pull out the motherboard from the case and set it on a cardboard box.  Install cpu and one RAM module and clear the CMOS.  Connect a monitor to the onboard video and connect the power supply.  See if it will at least boot to the BIOS with this configuration.  If it won't, you have a problem in the power supply, motherboard or cpu; for the motherboard or cpu, they will require a working opposite component to verify.

agree with the above two posters, since you already tried swapping the PSU (I assume you are CERTAIN the swapped PSU is 100% good at 700w) or a bad Mobo, could be a short in the Mobo, I've seen them fail right out of the box all too often
