opus 250w atx problem.

well i bought the opus 250w right when it came out, and noticed that off the bat the atx cable didnt look like it was meant to go there:

well last night I wired everything up and the cpu fan spins but nothing would post.

here is what I am trying to run on it, it should be able to handle it:

mAtx motherboard w/ onboard video with 3200+
1gb ram
250gb hd
wireless nic
gps (bu353, wasnt plugged in at the time)
7" lilliput (turned on, no input signal, tried home monitor as well, same thing)

I emailed opus to see what they say about the cable, and maybe theyll send me the right cable if that is the wrong one.

On a side note, I have a fused distribution block that I bought a long time ago and decided I should incorporate it in the system.

Well I wired everything and since I didnt have the correct fuses (anl style) I bridged the connections with a piece of wire for testing. When power was applied to it it made an awful high pitched squeal until the power was removed from it (bad ground? i don't think so since everything else worked).

You appear to need a 24-pin ATX connector. It's the newer ATX standard. It appears that Opus makes the new 250w PSU with only the 20-pin connector.

Here's a link to a 20-to-24 pin ATX adapter: http://www.saveateagle.com/wcab460-v...-V78&ovtac=CMP
It's not the only one out there i'm certain. It should at least give you a jumping off point.

i figured, im going to call opus and see if theyll send me the cable, i dont see the point in buying one if they didn't include the right one to begin with.

maybe you should have read the spec better?

I bought the psu in preperation. How is it my fault that the cables opus provides with the power supply aren't the right ones. I'd understand if they gave a 24pin to 24pin motherboard, but they included a 20pin all around and the actual power supply has a 24pin connector.

I think what Ste_nova means is that if you'd read the specs and compared them to your motherboard, you'd know that you need the 20-pin to 24-pin adapter.
I don't think Opus is going to supply you with the adapter you need or replace the unit with one that has the 24-pin connector. I could be wrong, since Opus is known to have top-notch customer service.

the motherboard is 20pin, i don't need an adapter for that. What I'm saying is that the cable that came with my opus powersupply is a 20pin (which is fine, connects right up to the motherboard) but the actual connector on the 250w opus is a 24pin, so I did not get the correct cable in the first place. How would I hook up a 20 pin cable to the 24pin connector on the powersupply without the correct cable.

[opus 250w: 24pin] <==> (provided cable: 20pin, both ends) <==> [motherboard: 20pin]

I don't see a reason for me having to spend more money on buying a cable to make the powersupply I purchased that already came with a cable but it did not fit into the actual powersupply.

Thats like buying a DVI only monitor, and it coming with a standard vga cord.

where did u buy the 250w opus?

DyeinBreed, an ATX 24 pin connector is only 4 pins bigger than a 20 atx, in the sens they are retro-compatible. Try to connect your 20-pins cable in the PSU atx connector (don't power it, who knows....), there should be only one way to do it.
