Power supply issues in new build?

[feikaidi]

Hi all, I'm building my first computer and having some issues. I'm thinking it's the power supply but not really sure.

Basically I put it all together (including case LEDs, etc.) and flipped on the PSU switch and immediately the CPU fan and video card fan were spinning, the wireless card LED was blinking, the case's hard drive and power LEDs were blinking, and the little speaker was clicking. Pressing the power button on the case did nothing (everything kept blinking/clicking). Nothing shows up on the monitor.

I took out everything except the video card, CPU+fan, and one stick of memory, and still, when I flip the switch on the PSU the fans start spinning but nothing on the monitor. I put a screwdriver on the power pegs and nothing changes about the situation. I should note that the PSU lacks a 2x4pin Molex for the ATX_12V_2x4 slot, so I put a 2x2 molex in the top half of it. The first time I flipped the PSU switch, I may not have had that plugged in... hoping I haven't done any irreparable damage!

My components are as follows:
Case: Linkworld 313-11 ATX mid tower with 500W PSU
CPU: AMD Phenom II X3 720 2.8GHz
Motherboard: Gigabyte GA-MA770T-UD3P
GPU: XFX NVidia GeForce 9500 GT
RAM: 3 x 2GB DDR3 G.Skill
HD: WD 640GB Caviar Black
DVD Burner Samsung SH-223L

Help, please? I should note that all desktops in my house are over 5 years old, so I'm not really sure if swapping parts would work too well. I plan to stay logged in, so I can answer any followup questions you might have. Thanks so much!

PROBLEMS with a NEW BUILD? Try This!!

Linkworld power supplies are total trash - so I'd get rid of it on general principle and get one with the right connectors. You need one that meets "EPS" specs.

That PSU by itself costs $15.99. There is no such thing as a decent quality $15.99 power supply, much less one that advertises 500 watts. It only has 20 amps on a single +12v rail, which is barely enough to run that video card.

What you need is something like this:

Thanks! Yeah, I looked at that sticky before posting, but as my issues weren't quite the same as the problems posted, I figured I'd ask here.

Any suggestion on a possibly cheaper (or at least easier to find) PSU? The one linked isn't currently for sale, and I'd preferably going to Microcenter in the next day or two to pick something up. A little impatient to work off something other than my 7" netbook

Also, might I have done any damage to the system by attempting to use the bad PSU? This is my first build, and while I've tried to take all precautions, I don't really know whether I've done it right.

Not the greatest, but it shouldn't blow up in your face. You REALLY need to follow the out of case procedure to validate your core components. I've been building for 15 years and do this with EVERY system I build.

Thanks so much. I did follow the procedure, but the same things were going on in and out of the case. I'll get a new PSU and start over... will post here again if I have issues, but hopefully it will work out. Thank you again!
