MSI MPOWER MAX 8pin cpu connectors

freemason · 27 Oct 2013 at 07:46

Dear all I've just build my new gaming system core components are as followed.

Case corsair obs 750d
Mobo z87 msi mpower max
Cpu 4770k
Cooler h100i
Gpu mdi 7950
Ram 8gig corsair vengeance 1800
Psu bequiet powerzone 750w

My question is

My motherboard supports 2x 8pin cpu connections but my psu only supports 1x 8 pin connection. Is there a cable of some sort i can plug in somewhere? So i can run power to the 2nd cpu 8pin connector. I have plenty of pci-e ports on the back of my psu..... Can i use Molex or perhaps sata power?

Any guidance would be welcome

I see 2 options.
First with 1 PCI-E being converted to 8-pin CPU connector.
Second with 2 cables that would split your single 8-pin CPU cable into 2.

YOUR BASKET
1 x Akasa PCI-E to ATX12V Cable Adapter (AK-CB051) £2.99
2 x Akasa 4 pin to 8 pin ATX PSU adapter cable (AK-CBPW10-15BK) £2.88 (£5.76)
Total : £12.66 (includes shipping : £3.26).

First should work without any problems.
Not sure if second option works with your PSU, so best to ask OCuk if you decide to do that.

You be fine operating with the one 8 pin connector.

If i push for 4.2ghz will i still be ok on the power draw from one 8pin?

How much do you need to overclock to use the 2nd 8pin?

Confused

Probably 5ghz plus with LN2!

Most people run with one 8 pin without issue with speeds in excess of 4ghz.

i use one 8pin on my board, can run at 4.9ghz if i want to.

Had a gigabyte board before that had a single 4pin and i could do 4.7 on that
