GA-M590-SLI-S5 won't boot

[iwrk4satan]

Here's my setup, everything is "new" ordered from newegg

Gigabyte GA-M59SLI-S5 motherboard
AMD64 x2 4600+
XFX GeForce 7600GT PCIe
Apevia (Aspire) X-Plorer ATX APEVIA (ASPIRE) X-Plorer ATXB8KLW-AL/ 420W Power Supply
2 GB 240-Pin DDR2 SDRAM 800

I've plugged in the 20+4 pin main power connector on my motherboard, but it seems my power supply only has a 4 pin 12v. Also on my motherboard is a slot provided for "12V_x2", which is a 8-pin slot, with 4 pins covered. I have read on another forum that it is necessary to plug into this slot with all 8 pins. Do I need to buy a 4 to 8 pin adapter? Or a new power supply (I kind of have the feeling now that 420W might seem kinda small for my setup).

Other than that, is there any easy way that I can tell whether the problem is in the PSU or if the motherboard was DOA?? All I can say is that I feel the motherboard start to get warm when everything is plugged in. No LCD, fans, or any beeps, etc when I turn on the power. I was planning on buying a DMM, but don't have one right now.

I'm basically just trying to troubleshoot and locate what might not be working properly, but this is my first build it from scratch project. Any help or suggestions at all would be greatly appreciated. Thanks.

Hi there and welcome to the forums.

You should consult your motherboard manufacturer's website to check the power requirements for the setup you have purchased.

Power supplies these days come in all different specs and with varying amounts and types of power leads. The last thing you want to do is plug in the incorrect lead into a spot on your motherboard (or video card for that matter) that is not required. Who knows what could happen, you could end up with fried components.

Try a barebones setup - take out your hard drives and only leave in the minimal amount of RAM. Remove any add-in cards. What you are trying to do is get your new system to POST and nothing more. You should only have: video card, mimimal RAM, proc & heatsink / fan, motherboard, power supply. I've done this a number of times without a case, of course making sure that I am properly grounded before I start touching things.

When you are building a new rig, getting to that POST screen is a big success - believe me, I've been there! Report back with any progress that you might have made. If you can't get it to POST, try powering up while holding the delete key - some manufacturers have this set to clear the CMOS memory. Alternatively you can consult your mobo manual on instructions to manually reset the CMOS memory. It's a last ditch effort but I have seen it bring many a "dead" board back to life.

Let's assume for now that none of your components are DOA Good luck.

Thanks for the thorough response. I've tried some things out, here's my update.

I tried the barebones setup with minimal RAM, CPU, and video card. Still nothing works. I got a chance to check the power supply leads with a DMM. For the ATX Power Supply, the POWER_GOOD lead was correctly at 3.6v, and the power switch was also receiving voltage, so I have a feeling that my Motherboard may be DOA. I checked some of the other pins, and they were definitely getting voltage, but some seemed to be different from the ones listed in my motherboard manual. From the online guides that I read, I should only really be cocerned with the PWR_GOOD pin, but I'm not sure. So I still receive absolutely no reaction when I try and turn the computer on.

Any help would be greatly appreciated. Thanks.
