No power for new PC build....YIKES!

New~
MSI B85-G41 PC Mate (flimsy board)
I7 4770 3.4
Intel stock CPU fan...piece of crap
16 GB DDR3 (1600-12800)
Seasonic S12g 550W PSU
EVGA GTX-750 (1GB) GPU. I wanted more but $$$
Samsung EVO 250GB SSD
Seagate 2TB HDD
WD 500GB HDD
ASUS 24x DVD/CD burner
...Also a Pioneer DVD/CD burner, but
unfortunately, it is IDE, can not use it!

Ok, I finished installing everything, (except the GPU) it stated I have to update the bios, before installing, really?)

I had a problem With the CoolerMaster Hyperlink 212 tower, 1150 socket was a small after thought on the box, but the original print had all sockets listed except for the 1150. I still had a problem with the small pin on the bottom of the CPU cooler that after the middle pin got into the hole, that small 1/8" pin on the left side caused the cross bracket not to fit. I cleaned off thermal paste, and just used the Intel stock fan.

When finished, I just happened to spin the CPU stock fan blade and the blades were hitting the aluminum heat sink, played with a while and now it's intermittent, (but not under power) It may free itself, hopefully.

Ok moment of truth arrived, I powered it on, then nothing. I checked all the wires again. Maybe it's the 7 year CoolerMaster 690, but in looking at the MSI B85-G41 board, it has a 9 pin JFP1, and. 7 Pin JFP1, I don't see any pinheads for this header, so I plugged the 9 pin into JFP1, where the case front panel connectors go. Is it one or the other?

I also bought a multiport 2.0/3.0 USB, and that 9 pin USB plugs into USB1, and the case top USB connectors plug into USB2 connectors. This multiplier also has a Sata and the 3.0 bigger connector next to the 24 pin ATX header.

I also have a 9 pin 1394 case connector (ground,cable pwr,tpb, ground, tpa,) It belonged to the FireWire on top of case, never used it with storage drives, just my 2.0 USB. goes, since it's old technology. I also used the onboard LAN for internet.
think I was using the I/O IEEE 1394 Ethernet plug, and my old board had a 1394 pinhead.

I should have looked over this board before buying, because I have a fairly new Pioneer DVD/CD burner, that is not Sata, but IDE, so now I have to buy another Sata burner. Also, while working on the board, it seems more flimsy than my MSI P-35.

Have a nice Day!

Goal: Assemble and run a bare-bones system outside of the case.

1. Remove EVERYTHING from the case.
   
   
2. Place the motherboard on a non-conductive surface, such as cardboard (motherboard box) or plywood. Do *-NOT-* place the motherboard on the anti-static bag! It can actually conduct electricity.
   
   
3. Install the CPU, thermal grease and heat sink. (Intel Guide / AMD Guide)
   
   
4. Install 1 RAM module (stick).
   
   
5. If applicable, install the video card and attach the power supply connection(s) to the card if your card needs it.
   
   
6. Connect the monitor to the video output.
   
   
7. Connect the power supply to the motherboard with both the 24-pin main ATX power connector and the separate 4- or 8-pin power connector.
   
   
8. Connect a power lead from the power supply to the power connector on the CPU fan.
   
   
9. Connect power to the power supply.
   
   
10. Do NOT connect ANYTHING else.
    
    
11. Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. When you momentarily touch both pins with a screwdriver, it will complete the circuit and boot the system.

With any luck the system should power up and you should get a display. If so, assemble these same parts into the case and try booting once again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.

If the system did not boot up, more often than not, you have a faulty component. Start swapping parts until you determine which one is defective. Best bet would be to start with the power supply.

Sorry, I posted the following in the Frankenstein Lab, before seeing this, and I'd like to park it here along withy other related posts. Can a MOD delete the Frankenstein thread? TY
Doc, thanks for the detailed info!
Just to let you know the latest...

AND THE LATEST...
After repeatedly testing ONLY these installed components,
(JFP1 pinheads, 24 ATX 24 power, 4+4 CPU power, and one stick of ram) by jumping the two top right pins for the POWER SWITCH, neg / pos, No power!

Then I removed the Mobo from the case, and tried the same thing OUTSIDE the case, on a non-conductive surface, and again...NADA.

So I'm getting this board RMA'D from Newegg.

This could be a coinkydink, or maybe the reason the Mobo stopped working all together, but like I said previously in one of my posts, when the CPU fan spun then abruptly stopped, this time I then unplugged the 3.0 plug that goes into the 3.0. Header just below the ATX header, (for my 3rd party multi- port 3.0/2.0 Bay slot, since this old case doesn't have 3.0 in the front.
*Once removed, the fans fired right up and stayed on until I shut it off.

I turned it on again, but no power at all, and that's when I started jumping pins in and out of the case. Could something like that short anything?
Anyway, when I get the new board, this time I'm going to add piece then check, until hopefully, it will all work together.
The standoffs did not come with my board, I used my other MSI P-35's standoff, so I'm guessing they are all universal in size to be flush with the I/O shield.

Did I miss anything? Thanks!

Yes.

Just an aside, standoffs don't come with motherboards, they come from and with computer cases. The only thing comes with motherboards is the cables and the l/O plate.
