Odd PSU Problem - Please help?

niteflite01 · 6 Oct 2006 at 17:37

Hi there,

I have an AMD 4000+ (o/c to 2.8GHz), 2GB RAM and a DFI NF4 INFINITY mobo. All of this, and 2 DVD drives, 1 SATA HDD and 1 IDE HDD, is powered by an Antec TruePower II 480W PSU, which I've had for about 5 months.

Now, I have a severe problem with the whole thing.

When I press the power button on the PC, the fans spin for about 1 second, then stop, and the PC refuses to start. This happens over, and over, and over again until eventually the whole thing cranks into life and works fine - no crashes etc.

I thought it may be a dodgy power switch on the case, to purchases a spanking new Antec case, but still the problem persists.

Could anyone please, please help, as I'm at my wits end

Cheers!

Try another psu or buy another psu.

You think that's the most likely problem?

niteflite01 · 6 Oct 2006 at 18:06

My voltages :

Core 1.4v
+3.3 - 3.31v
+12V - 11.9v
3.3dual - 2.94v

I had a very similar problem with my Antec Neopower (around 18 months old I think) just recently. It would take many tries before the system fired up properly, but once it did, all was OK until the next time I had to power it off. I've just replaced it with a Seasonic M12 inspired by some very favourable comments on these boards, and it is now absolutely fine. So I would agree with the suggestions that you try another PSU.

Yup that's exactly the same problem as I have

I'll try a new PSU - cheers for your help!

Just for anyone else with this problem, a new PSU sorted it, a 600W effort in fact.

Job done

Yeah, the 3.3V rail on the other PSU did seem low.

Some PSUs just do that to you - I had a Hiper that did exactly that (although it would never turn on ... ever), I got it RMAed and everything is fine.

Strange how it just came out of nowhere, after working fine for a good few months?
