Atx12v on gigabyte oc force - 8pin AND 4pin?

post #1 of 9
Thread Starter 
Seriously?!? What do I do? Seems like they just went from 4pin to 8pin, now all of a sudden I need 12 pins?

Can I use one or the other or am I boxing this up and taking it back? I can't swing another psu at the moment

Yes sir thats a 8 + 4 pin cpu connector. You will need both connected in order to run it. That is a PERDY mobo though. Hope you can make it work. I believe all z87x mobos require 8 + 4 you may need a new psu, May I recommend:

pending wattage requirements you could go down or up but a great psu for cost

That last 4-pin is meant for extreme overclocking only, you don't have to use it.

Oh thank god. Are u sure? And how extreme are we talking? I nearly got sick to my stomach. 4.8 on a 4770k isn't extreme right?

And yes it sure is pretty, but I'm disappointed I bought it over the Maximus due to the integrated watercooling and come to find out its 3/8 when I use 7/16 tubing. Can't change the barbs out so its useless to me frown.gif sucks!

Anyhow I appreciate the recommendation but after th cost of that I cannot afford a new psu for awhile. Just went from an ocz750 to a corsair hx850 cause my first z87 board (ud4h) required the 8 pin and now this one needs 4 more!!

(So long as your certain that when i put this all together it won't not post lol.)

I'm gonna see if anyone has a psu to trade for a spare 4770k I have NIB - if not ill be using this one for awhile so its imperative it works. (Posting this from my phone lol)

just ftr - it does/is running with just the one. Which im sure most of you knew. For those that didn't im living proof though. Whats ironic is my older much worse PSU has the 8+4 pin and this darn corsair hx850 doesn't?! blegh!

Does rosewill make good psu's? I always thought they were just so so if not worse than so so due to the price. Not that low price is always an indicator of shat but its a safe bet/starting place lol.

4 gtx480's (if I upgrade im gonna make it worth it, buying a psu alone is always so meh!) what size PSU to be safe? I have 3 running on this hx850 but im sure its pushing it pretty hard.

I imagine 1200 so I have some headroom? future cards if anything should be going down in power though ya?
post #7 of 9
1200 should be plenty of room. Rosewill takes psu from different suppliers. So really they are only good if you get the right ones. The capstone series is really one of there only great power supplies. If you need 1000+watts id recommend switching to Seasonic or similar.

Corsair also has the ax1200 which is decent:
http://www.amazon.com/Corsair-Professional-Series-Modular-AX1200/dp/B003PJ6QVU
or the ax1200i which is even better:
http://www.ebay.com/itm/CORSAIR-AXi-AX1200i-1200W-Digital-ATX12V-v2-31-and-EPS-2-92-SLI-Ready-CrossFire-/300951521071?pt=PCA_UPS&hash=item46121bc72f

or the x1250 from seasonic:
http://www.ebay.com/itm/Seasonic-X-1250-1250W-80Plus-Gold-EPS12V-ATX12V-Power-Supply-/190745475930?pt=US_Power_Supplies&hash=item2c6950fb5a
or the platinum from seasonic at 1000w which should be better then the x1250:
http://www.ebay.com/itm/Seasonic-PLATINUM-1000-SS-1000XP-80Plus-Platinum-EPS12V-ATX12V-Power-Supply-/190647588601?pt=PCA_UPS&hash=item2c637b56f9

theres always superflower who are the makers of the capstone series from rosewill:
http://www.ebay.com/itm/SuperFlower-SF-1000P14XE-Golden-Green-Crystal-80PLUS-Gold-Power-Supply-1000W-AT-/261253366588?pt=PCA_UPS&hash=item3cd3ea033c
only 1000watts but a great brand

heres EVGA's superflower aswell:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817438010
(best warranty of all of them comes with 10 years)

Lots of options out there just make sure you check reviews and verify quality aswell as verify you have a good warranty.

The 480 takes around 250w of power for a single gpu. When scaled into SLI they do not take the full 250 each, so i would imagine close to around 750watts with all 4running full speed. You should be ok with 1000watts (depending on your cooling system / rest of build). If you ever plan on water cooling though you will need 1200+. Also as you mentioned most newer cards are using less power so over time you should have even more room if you swap cards.

Unless your running 1.5v+ I would not worry about the 4 pin. I had 1.55v same board with just the 8pin no problem. Remember a 8 pin can push past 150w with no problem. Remember the AMD 955 C2? 140W. Ran overclocked on a 8 pin.

Awesome. Thanks a ton for the info guys. I ended up with some spare cash (doesnt happen too often and when it does let me tell you it is SO hard to spend it on a psu!) that being said, I wanted to future proof and had to choose between the AX1200i the ZX1250 and the NEX1500. I went with the latter. (U know that monster has a dip switch for OC mode 1650w!)

Lol hope I made the right choice. They are all overkill and obv w rating isn't king. Evga gpus have never done me wrong so.....
