That new build you helped me put together... Won't BOOT!

[meeshu]

Here's a screencap of the photo of the power supply on Newegg. There are 8-pin, 6-pin and 4-pin power connectors. Note the 4-pin connector in the upper right of the photo. If your PSU is the same, it should be coming off of a short lead from the 8-pin connector.

What is the Newegg link for that?

I believe the Rosewill APS-450CCP PSU is not available at Newegg (or elsewhere). It is an OEM unit!

Correct. As has been mentioned, the power supply with this case is not sold individually. Not on Newegg, not on the Roswill site. Based on what the OP has stated, he is reporting the same connections that Newegg has listed:
1 x 20+4-pin main connector
1 x ATX12V 4-pin connector
1 x PCI-E 6-pin connector
4 x SATA connector
2 x Molex 4-pin connector
1 x Floppy 3-pin connector

I don't see how you could have put a 6-pin connector on the 4-pin slot. Possibly it did slip on but did not seat, but I have honestly never tried this. They are both 12v connections, so I don't know that there was any damaged involved here.

OP, I will say that you would do well to go ahead and order a higher grade power supply, and swap them out to use the original as a backup.

 

[mfenn]

I also put in the ATX_12 cable in...(yes I missed this, although my last system didn't require it). However, the powersupply only came with a 6-pin (not 4), it's the only one colored blue, rest are white. I just put it in anyway leaving the right 2 pins empty.

Well, it sounds like you just plugged the PCIe 6-pin into the ATX12V port. Unfortunately, the PCIe connector and ATX12V have the pins swapped, so you shorted +12V to ground. Hopefully the deadness is the PSU's overcurrent protection is kicking in and you didn't fry anything.

Slight misinterpretation on my part. Sorry!

However, I believe it was this post by Chapbass that suggested the connector arrangement -

That doesn't sound right on the 6 pin there, zeze.

From newegg:
1 x Main connector (20+4Pin)
1 x 12V (P4) <---- This is the one you want right here
1 x 12V (8Pin)
2 x peripheral Quick release connectors
4 x SATA
1 x Floppy
1 x PCI-E <--- This could be 6 pin, its for a video card.


Looking at the pictures, I see the 20+4 pin (big connector with the attached green see-threw connector), then I see a 4 pin (should be black and yellow cables), I also see a 6 pin and an 8 pin. I'd double check that.

Not sure which specific PSU the above information was obtained from? It can't be for the APS-450CCP OEM unit as there is no information readily available for this unit.

But, unless I missed it, this connector arrangement has not as yet been confirmed or denied by zeze yet. So we still don't know for sure what the connector arrangement is for the OEM Rosewill APS-450CCP PSU.

 

[Carson Dyle]

My bad. I didn't check that part number closely enough on Newegg.

But here's a photo off of Newegg of the Rosewill FBM-01-450P case listed, showing the blue 6-pin PCIe power connector that was mentioned by the OP. It also shows an 8-pin connector, which looks as though it may be the type that slides apart into two 4-pin connectors. That would be where the 4-pin ATX connector is located.

"...four plus four pin CPU plug"

 

[VirtualLarry]

Update.

So I took the battery out and cleared CMOS.

I also put in the ATX_12 cable in...(yes I missed this, although my last system didn't require it). However, the powersupply only came with a 6-pin (not 4), it's the only one colored blue, rest are white. I just put it in anyway leaving the right 2 pins empty.

Now it won't even turn on. Absolutely nothing, just completely dead. Zero response to the power button.

It won't turn on at all with zero my initial config (prior to CMOS clear & without CPU ATX power).

W.T.F?

The PSU is Rosewill APS-450CCP

Uhh, that 6-pin is a PCI-E power connector, not the 4-pin ATX12V aux connector. In fact, I'm pretty certain it has a different pinout. Most certainly, though, they are NOT interchangable. I think that if you didn't fry something, you would be lucky.

Look closer, the PSU certainly has a 4-pin, or a 4+4pin, which is an 8-pin, that splits into two 4-pins. (Some mobos use an 8-pin EPS12V aux plug.)

 

[VirtualLarry]

I built a rig for a (now late) friend's daughter, and I had to replace the mobo, because she was getting blue screens, and being semi-computer-literate herself, she took it apart, and saw an unused floppy power connector, and an unused USB2.0 header on the mobo, and somehow determined in her head that those must have been the issue, and plugged then into each other. Needless to say, she fried the mobo when it was powered on next time.

Zeze, you are making these kind of mistakes. If you didn't already fry your mobo (by plugging the PCI-E power into the ATX12V power), I would attempt to get someone locally to help you, that has built a system before.

Edit: Late friend, not late daughter. Just to clarify.

 

[Ketchup]

I can't help but wonder if he had an 8-pin, (not a 4-pin as listed), and the item was updated since Newegg listed it. Like I said earlier, I don't see how he could get a 6-pin to fit.

 

[Carson Dyle]

Here's how. It's a "round peg in a square hole" thing. The leftmost 4 pins on the PCIe plug (looking at it from the front) can be fit into the 4-pin ATX socket.

In this diagram, only pin 5 (the blue one) of the PCIe connector is different, but since it's a rounded pin, it will fit into the square hole in the socket.

 

[meeshu]

From further research, the Rosewill APS-450CCP PSU has been used on motherboards with 8 pin ATX 12V auxiliary CPU sockets. This suggests that the APS-450CCP must have an 8 pin (or maybe 2 x 4 pin) ATX 12V auxiliary connector(s). But whether there is/are 4 pin(s) ATX 12V auxiliary connector available with the APS-450CCP PSU is still unclear.

The motherboard (GA-H81M-H) used with Zeze's build requires a 4 pin ATX 12V auxiliary connector from the PSU. But at this stage it appears that the APS-450CCP PSU doesn't seem to have the required 4 pin connector (as per Zeze's post below), so the system can't be fully powered up?

So from this it seems the APS-450CCP PSU connector arrangement (8 pin ATX 12V) is not pin to pin compatible with the selected motherboard (4 pin ATX 12V). But, assuming that the APS-450CCP PSU uses a 8 pin connector (or possibly 2 x 4 pin connectors side by side, which may look like an 8 pin connector), it is possible to use the 8 pin connector on a 4 pin socket, space permitting, with 4 pins of the 8 pin connector overhanging the 4 pin motherboard socket.

Basically, at this time, and from post number 13 -

Update.

So I took the battery out and cleared CMOS.

I also put in the ATX_12 cable in...(yes I missed this, although my last system didn't require it). However, the powersupply only came with a 6-pin (not 4), it's the only one colored blue, rest are white. I just put it in anyway leaving the right 2 pins empty.

The PSU is Rosewill APS-450CCP

it appears there was some confusion in that a PCI-e 6 pin connector from APS-450CCP PSU was mistaken for the ATX 12V connector, in the process of trying to get the system to boot. The PCI-e 6 pin connector was forced into the motherboard 4 pin ATX 12V auxiliary socket, with a possibility of electrical damage to either the motherboard or to the APS-450CCP PSU, or maybe damage to both.

Options now are -

1) Get another quality PSU that has a 4 pin (preferable, or 2 x 4 pin) ATX 12V auxiliary connector(s) and try this PSU on the motherboard, which is hopefully not damaged.

or,

2) Assuming the APS-450CCP PSU has 8 pin (or 2 x 4 pin) ATX 12V connector(s) get another motherboard that has an 8 pin ATX 12V auxiliary socket, or a motherboard with 4 pin ATX 12V auxiliary socket IF the APS-450CCP PSU has 2 x 4 pin connectors, and try the APS-450CCP PSU with it. Hopefully the PSU is not damaged.

or,

3) Get another quality PSU and another motherboard, making sure that the PSU has, preferably, either or both 8 and/or 4 pin ATX 12V auxiliary connector(s) to match the corresponding 8 or 4 pin ATX 12V socket on the motherboard.

 

[Ketchup]

From further research, the Rosewill APS-450CCP PSU has been used on motherboards with 8 pin ATX 12V auxiliary CPU sockets. So the APS-450CCP must have at least an 8 pin ATX 12V auxiliary connector. ...

Not at all. Considering the power supply supplies stable power, a 4 pin connector will work perfectly fine on a motherboard with the 8-pin CPU connector. The inverse should also work perfectly fine.

So it seems the APS-450CCP PSU connector arrangement (8 pin ATX 12V) is not compatible with the selected motherboard (4 pin ATX 12V).

Where are you getting this?

 

[meeshu]

In terms of pin to pin connectivity, 4 pin PSU ATX 12V connector would usually go into a 4 pin ATX 12V socket on the motherboard. And an 8 pin PSU ATX 12V connector would usually go into an 8 pin ATX 12V motherboard socket.

For the motherboards that required 8 pin ATX 12V connection and were powered by an APS-450CCP PSU, it was assumed that the PSU's had 8 pin ATX 12V connector to match. Although it is possible that 2 x 4 pin PSU connectors in parallel may have been used (less likely, but possible). In the worst case a single 4 pin PSU connector may have been used in the 8 pin motherboard socket.

Plugging a 4 pin PSU connector into an 8 pin motherboard socket will sometimes work, but sometimes not. And there is some risk of overloading and damaging the 4 pin connector, especially if overclocking and/or during heavy gaming or graphics work.

Plugging an 8 pin PSU connector into a 4 pin motherboard socket is possible, if there is room to do so, with 4 pins of the connector overhanging the socket, which may or may not cause other (obstruction) issues.

Generally, it is recommended and usual to match connectors and corresponding sockets pin for pin for esthetic and technical reasons.

 

[Carson Dyle]

See my replies above. A 4+4 pin plug is shown in both the photo and the video.

 

[meeshu]

Yes, 2 x 4 pin connectors do work as well as 8 pin connectors.

The question is, does the APS-450CCP PSU use an 8 pin ATX 12V connector, or does it use 2 x 4 pin connectors instead?

Further to my earlier post, it is suggested that the OP carry out the following procedure.

1) Check the APS-450CCP PSU's connectors closely again for either an 8 pin, 2 x 4 pin, or for a 4 pin ATX 12V auxiliary connector(s). The PSU MUST have one of these options. Refer to photos posted here for guidance. Then carefully (don't force it, and note slight variation in pin/connector shapes which must match corresponding socket shapes on motherboard) install the appropriate connector into the motherboard, and making sure all other connections are made also. See how system goes. If system fails to boot/run then the PSU and/or motherboard may be faulty/damaged.

2) Get another quality PSU, preferably with 2 x 4 pin ATX 12V connectors (and plug ONE of the 4 pin connectors into the motherboard socket), and see if the system boots and runs. If it does run then the original APS-450CCP PSU is probably faulty/damaged. If the system still fails to boot/run then the motherboard is likely to be faulty/damaged.

3) Get another motherboard. It can use either one 4 pin ATX 12V socket, or it can use an 8 pin ATX 12V socket (note, recommend using both of the 4 pin PSU connectors at the same time here). Try the system again. If there are still issues with booting/running then other options will be considered.

 

[mfenn]

See my replies above. A 4+4 pin plug is shown in both the photo and the video.

Agree. I've never seen a PSU that doesn't either have a separate 4-pin or a 4+4 combo connector. I think it's extremely unlikely that the PSU would come with only a solid 8-pin.

 

[meeshu]

Actually my PC Power & Cooling PSU uses an 8 pin connector. It is definitely not a 2 x 4 pin connector arrangement.

 

[Zeze]

Problem solved. I just had to use split the 4+4 pin and plug it in the CPU power connector (ATX_12).

It's up and running now.

Thanks all for putting up with my noobery. To be honest, I haven't come across any boards that required doing this since the 90's.

That's good news! I'm glad that the mobo wasn't damaged, and the PSU appears to be working correctly as well.

 

[meeshu]

Yes. Thanks for the feedback!

There was a real possibility that either the PSU or the motherboard may have been damaged due to making wrong connections to the ATX 12V socket. But fortunately it appears this wasn't the case.

Now we also know that the APS-450CCP PSU has 2 x 4 pin ATX 12V connectors.

Pretty sure P4 boards (circa 2000 or 2001) already come with 12V AUX connector. That, or the AMD socket 939 (circa 2004) will require it.

What the story on 4 DIMMs for a 2 DIMM MB?

System ordered!

I was closed to getting that super mini system (ITX whatever), but ended up sticking with the conventional microATX this time.

Zeze is probably thinking even older than that though. Back in the AT days you had to plug two power cables into the board, but they of course weren't keyed, and plugging them in the wrong way resulted in instant smoke. We've come a long way with keyed connectors and protection circuits (thankfully!).
