Power supply question

[techwanabe]

This is a first for me but ordered a HIPRO 300W power supply to replace a bad one in my daughters computer. The computer has an ABIT ST-6 motherboard of ATX configuration IIRC.

The HIPRO power supply I thought was an ATX 300W type. So I go to install it and noticed right away the cable to the mother board doesn't match - first time I have had this happen. The HIPRO P/S cable has 12 pairs of plugs on the wide motherboard connector while the motherboard socket has only 10 rows. What gives? Where did I go wrong?

I guess I'll have to RMA this puppy to New Egg and find out what I really need. Feed back?

You have the 24 pin connector on the PSU. Most of these connectors can be configured for 20 pins by sliding out the last 4 pins. If this is not the case, then you would need an adapter 20-24 pin connector.

You can just let the extra 4 pins hang off the end assuming there's nothing in the way.

Hmmm.... this is a first!

One side butts up against some capacitors - I'll see if there is any why I can make it fit. Like which for can be left off?

If you look at the connector with the tab clip on the top, is it the right side or left side that you can omit the last 4 pins?

 

[polypterus]

It'll only fit one way, match the tab with the tab on the motherboard and you'll see where it hangs off. Like this.

I knew it, the extra part hand off where the capacitors are. Well, I guess finding and adapter would save me having to RMA the thing.

Thanks, I'll look for an adapter!

Be careful you get the right one, they have 20 to 24 and 24 to 20. You want this one.

Or just cut off the plastic for the extra 4 pins if you can. Make sure not to cut any wires though.

Yeah, I was thinking of cutting off the last four on the left side with the pin snap up. I don't think I have an exacto blade handy. I'll see if I can round up a connector with a 24 pin female and 20 pin male. Hopefully they I can find one at maybe radio shack.

When did these 24 pin conectors become popular - never seen one and I just replaced a power supply in my home built PC 6 months ago - a machine based on the Epox 8RDA+ Nforce 2 chipset motherboard/AMD Athlon 2500+Barton.

The 24-pin power connector is part of ATX EPS, 2.0, and 2.2 Specifications. Those specifications became more mainstream with Socket939 and LGA775 mobos. Most PSU's use a 20+4 configuration, like so:

If you notice, the right 4 pins can be disconnected from the main 20-pin connector.

Too bad they all aren't made like that. The one I bought is a one piece plug and nothing short of cutting it would make it fit. I'll have to hunt for an adaptor, or go find my old hobby razor saw.

I'm resurrecting this thread. I cut off the left four plugs on my 24 pin connector (with the hook on the top). I just plugged it into the motherboard on the Abit ST6 motherboard. Then plugged in the power cord and tried turning it on. The power light on the front blinked once and then nothing. I disconnected the motherboard cable and did it again, same thing. Computer isn't powering up. What is going on now? Help!

Your power supply may be underpowered. I had this happen to me and I bought a more powerful power supply with more amps on the +12V. Computer started right up. Can you borrow a more powerful PSU from someone and give it a try?

Good grief, that shouldn't be the problem. This computer was running on a 250 watt before and the supply I just put in is a 300W. It was a cheap HIPRO but... now that I cut the power plug I probably am stuck with it.

BTW, the original power supply from the computer in question is in the one I'm typing on now. It's an Emachines who's power supply died. I robbed the P/S out of my daughters computer to get this one working for her mother. I could always take it back out but this one is needed for work when she is home.
