technical question. I am kinda stumped here NOW WITH SHIPPING PICS

So here's my setup
all brand new..

Gigabyte K8N-Pro-SLI motherboard
AMD 64 3500+ Newcastle
Enermax 650W psu
1 Gig of Corsair XMS Twinx pc 3200 DDR400
gigabyte wireless pci card
2 hard drives ide maxtor and western digital
1 dvd-rw drive..

ok so my problem is I can't get my computer to power on at all.. I see the lights flicker when I plug int he power supply tot he wallw hich is a good sign as usual. i checked all the connections. I don't have a video card yet because the baor donly accepts PCI-X so I am awaiting that right now.. but I figured the board would power up anyway without it? at least turn on the cpu fan or psu fan.. but I get nothing at all.. I tried flipping the polarity of the power supply switch jumper in case I had it plugged in upside down tot he motherboard.. still no go. I reset the cmos. I am kinda stumped as what to do next and the power supply is not new I bought it from someone here on the forums, but I assume it's capable of powering this motherboard.. oh also the 12v connector is plugge din firmly.. I reconnected the atx connector just in case. so still no go.. the ram is seated properly. i get absolutely nothing. Can a board powerup without a video card??
 
Thanks thats all i needed to know, was just curious if something might ahve been dead, but nothing should be it should all work.. so just reassuring myself that if I DO NOT have any type of video card plugged into any slot the computer will not power up regardless.. no beeps no motherboardfan no nothing correct?
 
hmm I am gonna go back upstairs and try some other things.. I should be able to make this work I am just not trying hard enough..time to remove everything and start at square one.. thanks for the input guys.

Sorry I couldn't be more help LiquidIce1337 🙁
 
I don't have any bright ideas either besides the usual strip it down, add back piece by piece.

Check your manual for beep codes and if there are diagnostic LEDs on the motherboard. I did double-check and in the first manual I grabbed (Asus CUSL2-C) the video card beep code is one very long then 3 short.
 
I gotta go downstairs tot he graveyard and swipe a pc speaker.. antec lanboy doesn't come with one unforuntately.. so I don't even know if I have any beep codes going off.. but I don't see any lights on the motherboard anywhere to show that is has power reaching the motherboard.. so it's kinda odd right now I'll be back with results.. probably end up stripping it down removing all add in card ( just the wireless card) and see if it powers up then.. it's jumperless.. but I'll clear the cmos again.. hopefully it's something I just missed. I am worried though if this power supply cna handle powering an athlon 64 board.

It's an Enermax 615

do you guys think this is sufficient?
 
550w is more than sufficient to just boot your rig LiquidIce1337, I'm using a Antec 380w PS in my current rig which includes an A64 3200+, 2GB of RAM, 120GB HD, an AIW Radeon 9800 Pro, Samsung SD-816B & a Sony DRU-510A.
 
Ok, so far so good.. Umm so I tried adding a pc speaker on.. i unconnected everything started from scratch reseated the cpu and memory.. checked to see if anyhting was shorting form a brass stand or anything at all.. still no luck powering up... I don't know aboutt his power supply though I am not positive it is a working power supply.. is there anyway to test it besides putting it in another system? I don't have a tester but is there some backhand way of testing it? I noticed on the atx connector to the board there is 1 green wire hanging out with a red cap in between in, I'll take a picture in a min but it also has another greenwire piggy backed next to it int he atx connector so it looks like it was an addon or something.. but the end of the wire is just cut.. so I am a little shaky I pmed the guy that I bought it from but he hasnt responded yet.. he had great heatware reviews over 60+ no negative.. so I don't think he'd send something that was defective.. I'l get pics soon.

I don't know how this helps me though, what do you mean I know pci-e is pci express and I alwasy thought pci-x meant the same just a slang way.. enlighten me.. also does this mean if I had a pci-x slot for my video card instead of pci-e it wouldn't power.. im confused
 
Just remove the motherboard from the case. Connect the power supply, CPU and memory and attempt to boot it. It should turn on and give you a beep or a voice should come on the speakers saying that there is no video card present. It's more than likely something is grounded and or something is not in tight. How many sticks of memory do you have? You can try putting in one at a time.
 
Jeeze, no go I tried alot of stuff, pulled mobo out put it in a cardboard box with speaker and atx power sw and power and 1 stick of ram.. tried both sticks of ram and none.. wouldn't power at all..
 
green is the power on wire - if its grounded to a black wire, it turns on the PS.

looks like he was making a remote turn on/reset button switch, then when he sold it to you, he just cut it off
Whats really strange is both green wires are the same manufacturer, implying it came that way.
What is the exact name and model and wattage rating on the PSU??

http://www.powerstream.com/itx-atx-pinout.htm

and PCI-X is 64 bit PCI slot for server boards
the PCI slots in your mobo are 32 bit.

PCI-E is PCI Express.
PCI-X is PCI Extended.

Not the same thing.
 
here's the info

Enermax
switching power supply

Model: EG651P-V(E)
AC INPUT | 115V/230V ~13A/8A, 50-60 hz
DC OUTPUT | +3.3V | +5V | +12V | -5V | -12V | Vsb
| 40A | 45A | 25A | 1A | 1A | 1.8A
+5V, +3.3V, +12V TOTAL MAX 525W
+5V, +3.3V, TOTAL MAX 300W TOTAL 550W, PICK 650W


thats verbatim fromt he PSU
 
flick the little 230V switch to 115V on the back of the power supply..

had this problem once before..

I'd bet $1 that's the problem.
 
heres a pic from an old review - dont see 2 greens
http://www.ocworkbench.com/hardware/enermax/eg651/Image6.htm

but this model has been around for so long (they now have a 24 pin ATX vers) its kinda hard to say for sure

looks like the guy you bought it from had a watercooling setup
I wonder if he was using the green to turn on his water pump

well, wait for his response - see what he says
the extra wire makes no dif tho, as long as inner wire doesnt touch anything

you could use a DMM (Digital multimeter) to test the voltages with the needle probes in the molex with ground in a black hole
