So what IS the problem?

[BovineKid]

I just built my first ever system (sort of). It's not posting, and I suspect the PSU may be my problem. My MB (abit IP35v link) takes a 4-pin ATX_12V, but my power supply (Silverstone ST50F link) has an 8-pin ATX_12V. Someone on Newegg who purchased the same PSU said he got his to work by just plugging in 4 of the 8 pins. I tried this, though I'm not sure which 4 to use. Also, there are only 4 that I can use since a transistor gets in the way if I try to use the other 4.

I haven't ruled out anything else as the reason I'm not posting. Can I work with what I have? Can I get some kind of adapter? Or do I just need to buy another PSU?

I posted this in the power supply forum also, but I figured it'd get more traffic here.

Thanks!

The 4pin design on mobo is foolproof. You can plug it in only one way.

If you can fit both halves of 8 pin, plug in one that you can plug in (one without which transistor in the way).

You can use either of half, so plug in any half.

I was hoping you can "break" the 8 pin in two 4 pin (both 4 pin are identical, thus you can use either 4).

My PSU came with two 4pin plugs and mobo that required 8 pins, so I just plugged them both in and it works well.

Thanks. The good news is that I don't have to buy a new power supply. The bad news is that there is probably something else wrong with my build. :frown:

Probably should be a different topic, but I'll ask anyway. The LED on my mobo is lighting up, but I'm not getting a beep. I also don't have a monitor yet, because my mobo has no on-board video, and I haven't installed my graphics card yet (it will be on my front porch when I get home from work today). This is mostly wishful thinking, but is it possible that the a board with no video won't post until it has a video card plugged in?

If that isn't the probably, I'm kinda worried now. Having to buy another power supply would have sucked, but at least it's easy.

I changed the topic so it would make more sense for the new question, although I guess it's pretty vague now.

Just wait for your video card
Perhaps you didn't connect the case speaker?

Your basing your non post to nothing but PC speaker sound? Do yourself a FAVOR... Wait till you have a full machine.. My last build didnt post (I was able to WATCH it on my monitor :beer and it was because I didnt plug my PSU into the video card..
So in effect IMO it was not posting because there was no video card.. I suspect you are in the same boat with no "on board" or "no card".. Patience is KEY when building...

Seems you were right. I got home and stuck the 8800GT in and everything seems fine now. Still no beeping though. I don't recall seeing/connecting a case speaker. Maybe mine doesn't even have one. Anyway, installing OS now.

My new Case (Christmas present:thumbsup has a one inch wire, with a connector on it and a round half inch plastic disk on the other end...
And the hard black plastic connector was labeled SPEAKER LOL...
Maybe new cases are getting away from actual speakers.... I would call this more of a buzzer LOL...

It does grunt and buzzzz on start ups....
