Cooler Master 330 with Asus P7H55 Not Working

the-fridge86 · 13 Mar 2011 at 19:38

Hi,

I've just put together the following rig but it won't power up:

Coolermaster Elite 330 Case With Coolermaster Elite 460W PSU
Intel Core i5 650 3.20GHz Socket 1156 4MB L3 cache retail Box Processor
ASUS P7H55-M H55 Socket 1156 VGA HDMI Out 8 Channel Audio MATX Motherboard
LiteOn iHOS104 4x BD-ROM SATA Blu-Ray Drive - OEM Black
Seagate ST31000528AS 1TB Hard Drive SATAII 7200rpm 32MB Cache - OEM
Sapphire HD 5570 2GB DDR3 VGA DVI HDMI PCI-E Graphics Card
OCZ 4GB (2x2GB) DDR3 1600MHz/PC3-12800 Gold i5 Memory Kit 1.65V CL8(8-8-8-24)

The power supply has a 4-pin and a 20-pin whereas the the asus motherboard has sockets for 8-pin and 24-pin so I'm not sure if maybe that's where the problem starts. The motherboard's power LED lights up fine but the power and reset buttons from the front panel of the case don't do anything even though they seem to be connected properly to the board.

I know it's pretty vague but does anyone have any ideas what I might be doing wrong?

Would really appreciate any tips as, right now, I'm completely stuck!!

Thanks,

having a look at your PSU you should find that it has enough connectors.
It should have a 20+4 and a 4+4 pin connector.
have a look on here and see if you can identify them:

Welcome to the forum

I would have thought the psu would have 24 pin main atx connector 4 + 20 and most probably a 4 pin for CPU power.

Another thing is to check is the memory is in slots 2 and 4 away from the CPU socket.

Hey, thanks a lot for your help. I've now got the 4+4 and the 20+4 connected. A little bit embarrassed by how stupid I must be to have missed the right configuration there (my first build). RAM is in slots A1 and B1 (slots 2 and 4 away from the CPU socket). Still nothing from front panel despite mobo LED light on. Is there anything else I might be missing?

R088ieS86 · 13 Mar 2011 at 20:47

It sounds like your front pannel isn't connected up right then.

Take the cables out and start again. IDE LED might be labled HDD LED.

the-fridge86 · 13 Mar 2011 at 21:03

Thanks. I just tried that to no avail. Is there anything else it could be?

R088ieS86 · 13 Mar 2011 at 21:22

Try taking out your graphics card and one of your RAM modules, plug your monitor into the onboard graphics. and try powering it on.

the-fridge86 · 13 Mar 2011 at 21:39

OK. Tried tagging out a RAM module and powering on. Still nothing. I've not had my monitor (TV via HDMI) plugged in all this time because I thought the monitor would be independent of any issues so I'd plug it in last. I'm hesitant to take the graphics card out as I'd need to also unscrew the motherboard, which was a complete pain to get in and align with the rear interface.. Isn't the monitor independent from the issue?

R088ieS86 · 13 Mar 2011 at 21:49

really? why would the mobo need to be unscrewed?
sorry i was presuming you had it plugged in, don't worry about the monitor then leave it unplugged.
Any chance you could take a pic of the inside of the case so we can see the wiring etc?

RJC · 13 Mar 2011 at 21:53

Have you tried a CMOS reset.

the-fridge86 · 13 Mar 2011 at 22:31

Yeah, the way the graphics card slots in means taking the mobo out a bit to get it out. RE a CMOS reset, all the equipment is brand new and hasn't been powered up yet. Hope these photos help. Let me know if you need close-ups on anything as to me it all looks pretty unclear!

Woah, those photos are bigger than I realised!!

Did you put the motherboard standoffs in?

the-fridge86 · 13 Mar 2011 at 22:42

Yes about the standoffs

Surveyor · 13 Mar 2011 at 23:03

Does anything happen at all when you switch it on?

Might be a dead power supply.

You could try testing it using this method by attaching a fan to one of the molex connectors and then shorting pins 14 & 15 to see if the fan spins:

Do this at your own risk!!!

P.S.

Are you sure you've put it together correctly? I've never had a system where the motherboard had to be removed to take out a graphics card. Are you sure nothing is misaligned?

the-fridge86 · 13 Mar 2011 at 23:09

Nothing happens at all. I don't think I'm at the point yet when I want to start shorting things! Thanks, though, I'll bear it in mind.

(the motherboard's power LED is on but the on/off switch on the front panel of the case does nothing)

The power LED should only be on when the system is running.

If it's on permanently something is wrong, possibly with your wiring.

Check that all of the front panel connectors (power switch, reset switch, power LED and HDD LED) are connected correctly.

the-fridge86 · 14 Mar 2011 at 07:54

According to the manual, the motherboard's power LED is on when the system is on, standby or soft-off mode. In other words, I think it's always on as long as the power cable's in the back and the on/off switch at the back is on. The problem at the moment is with the on/off switch on the front panel, which should start up the machine and currently does nothing. It seems like it's stuck in soft-off mode.

Do you have the front panle plugs the right way around? If you look on the plugs there should be a little triangle/arrow which means that side is + (positive).

Make sure that the 8/24 pin plugs are in all the way. They can be quite tight sometimes.
