Part Way Through Build - Urgent Help on Power

toocanx · 22 Jan 2014 at 19:38

First build in 15 or so years so struggling!

In terms of the power to the motherboard do I connect the adjacent 4 block into the end or not? as per the pic

In terms of the Graphics card (r290) do I connect 6 chocka to the end e.g.

OR/AND

do I connect the 6 chock + the 2 chock to the next one down the card e.g.

I dont think you need to, but you may as well plug it in for 'better' power. My brain has died on me, I'm sure you know what I mean.

As for the graphics card, You will need to connect a wire to both the 6 pin and the 8 pin.

The 4 pin motherboard connector will need to be plugged in. The connector should attach to the main 20 pin connector to make a 24 pin connector. There are usually small tabs that interlock with each other.

The graphics card needs both the 6 pin and 6+2 pin connectors, so the 6 pin goes into the 6 pin socket and the 6+2 into the 8 pin socket.

OK so basically fill ALL the holes! the extra 4 for the mobo and both the 6 and the 8 on the gfx card?

Yes,

And that is all a great life motto.

Yes to the mobo connectors and for piece of mind a quick search to confirm the power connections for the R9 290 as well!

That is correct.

ive just noticed a cable that says cpu1 and a empty block under the fan labelled "ATX 12v 2x4" (it would have to be after i fitted the bloody fan).. Do I need to connect this if ive connected the main 24 pin connector?

lee32uk · 22 Jan 2014 at 20:14

That needs plugging in as well

RICKST20 · 22 Jan 2014 at 20:16

Yes you will also need to plug these in. If your mobo requires the 2 4pin connectors (or has space for them both) then they need filling to.

ugh. gonna have to take the heatsink off. Is it a bad idea to mix thermal pastes (different makes?)

Also ive connected the gfx card as follows just using one cable from the power supply should i use 2?

RICKST20 · 22 Jan 2014 at 20:36

With that gfx id be inclined to use both cables if you have them. Takes the load of of just one of the cables and spreads it evenly across the two then. Plus you may as well use the wires instead of hiding them inside the case somewhere.
However id avoid removing the heat sink if you can. Im sure you will have space to wiggle them in there. But if you really have to id advise starting a fresh with the paste. Im not sure on how mixing compounds would affect the heat transfer, but personally if it was me id start a fresh rather than mix them.

I'm assuming you are talking about the CPU so yes it is a bad idea. Clean the old stuff off and apply new stuff.

Yes, you need to plug in both connectors, so both the six and eight pin sockets are full. You may use one cable from the PSU (if it is split into two) or use two separate cables from the PSU.

There's no 'like' button on here but too true sir, too true!!!

toocanx · 22 Jan 2014 at 21:18

thanks for the help guys, and life advice

there was an overspill of paste from the cooler so i moved it back on the chip and on the cooler. Bios has been on for 15 mins and it seems to be steady at 25C

One annoying this is the cpu gives out a high pitched sound - not ideal

It's far more likely to be the PSU or graphics card (or combination of both). You can try using two separate PCIe cables between the graphics cards and the PSU. Or you can try wearing in the coil that's whining by leaving it running something very heavy for a day.

Search the forum for "coil whine" and you'll probably get loads of things to try.

Hi its definately the cpu fan. If I put my finger on the fan to stop it the high pitch wine stops, then when the fans spins up it happens again. I tried loosing the fan very slightly ontop of the heatsink but no joy.. any suggestions

So it's not the CPU, it's the CPU fan.

Are you sure you have installed any buffers or anti vibration pads between the heatsink and the fan? Is the fan tight on the heatsink so it's not vibrating against it? Have you set the motherboard to control the fan speed as the fan shouldn't need to run full speed all the time?

I don't know the Gigabyte boards, so I don't know if they come with fan control software like the Asus boards do, but the BIOS should do some kind of fan control.
