Power supply with TWO 8-pin CPU power plugs

I'm having some trouble finding the ideal power supply here.

I have the following motherboard:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16813182348

It has TWO 8-pin power ports for CPU power. I need to find an ATX power supply that will support this.

According to eXtreme's power supply calculator, I need minimum 560 watts, recommended 610 watts or more.

Can somebody recommend a power supply from Canada's Newegg.ca that will work?

The CORSAIR CMPSU-750TX specifications tab doesn't mention it having two EPS plugs, but the pictures clearly show two 8-pin CPU plugs:CORSAIR CMPSU-750TX

The specs tab for the modular CORSAIR AX760 does list two EPS plugs, and it looks like there's room to plug in six of them, though that would reduce the 6+2 PCIe plugs to zero.

One more... the Seasonic X650 currently has a promo code showing for $20 off, but it expires today. If you're ready to buy, that would make it the least expensive of the three I found there... but personally I kinda dislike making decisions on $100+ purchases with a time constraint.  :-|

"... The CORSAIR CMPSU-750TX specifications tab doesn't mention it having two EPS plugs ..."  ==>  Actually, Corsair's specifications clearly show that the TX750 has two EPS connectors (as does the TX850)  ...

Corsair Connectors

HOWEVER ... I'd recommend going with the higher-end HX series.    The HX750, HX850, and HX1050 all have 2 EPS connectors, so you can get as high a wattage as you want, depending on just how you plan to populate your system.    The HX750 has a nice rebate at the moment:   http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139010

I was referring to the specifications tab on the page of the newegg.ca link I gave...  where it (incorrectly) lists only

1 x Main connector (20+4Pin)
1 x 12V(4/8Pin)
8 x Peripheral
8 x SATA
2 x Floppy
4 x PCI-E


i.e. the second line should say
2 x 12V(4/8Pin)

Yes, I noticed that.   But note that the chart I pasted above is on the page your link goes to :-)

That's really weird... the HX750's Specifications tab there also says just one EPS plug:

1 x Main connector (20+4Pin)
1 x 8-Pin EPS 12V
8 x Peripheral
12 x SATA
2 x Floppy
4 x PCI-E


I've never noticed Newegg's info to be wrong on so many items.
I wonder if the newegg.ca and newegg.com sites are maintained by the same people.

On the newegg.com site, the HX750 currently has a promo code for an instant $25 off, which brings it down to $105 USD (that's prior to the $20 mail-in-rebate... so it would be $85 if that can be cashed in CAN).

No idea what the charge would be for handover from UPS to Canada Post... (or does UPS run in CAN, too?)

Just to point out another mistake, the TX850 Efficiency at 115V in the chart above must be 87% not 97% since auto-ranging PSUs are always more efficient at 230v than at 115V.

Ahh now I know what it's called - an EPS plug.

I've always liked Corsair's power supplies. And since NewEgg has demonstrated that sometimes their specs are wrong... lets just use Corsair's website directly.

What the heck? One is listed with 1x EPS plug, the other is listed with 2x EPS plugs. What's the difference between these two?

That's probably correct => Corsair's site could also get it wrong;  but it's probably a bit less likely.    I'm surprised the HX750 doesn't have two EPS plugs;  but given the choices you've listed, I'd go with the HX850

Gary CaseRetiredCommented:
You edited your note while I was writing the above :-)   ... but nevertheless I'd go with the HX850.    It seems they've improved it from 80+ Silver to 80+ Gold, and the newer version has 2 EPS plugs.

HOWEVER ... the HX850 Gold on Newegg has a chart on the Overview page that shows 2 EPS plugs;  but lists 1 EPS plug on the Specs tab !!!

Hard to say exactly what's right with these disparities.    I suspect that EITHER the TX or HX 850w versions have 2 EPS plugs;  but it's hard to really say for sure with the clearly not-well-validated details on both Corsair and Newegg's sites.

Hmm okay. I think you've hit the nail on the head there with one of my links showing the HX 850  as 80+ Silver, and the other one showing it as 80+ Gold. perhaps Corsair had an earlier revision of what they are calling the "HX850" which was Silver, and 1x EPS plug, and it was superceded by this more recent model which is Gold with 2x EPS plugs.

My distributor has the HX850 and states that it is the 80 PLUS Gold one... so hopefully that's the later model with the 2x EPS plugs. I'll place the order today. Fingers crossed, I'll let you know what the result was!

I don't know how Corsair decides which ones get 1 EPS plug and which ones get 2, but here is the Silver/Gold designations:

The HX 850 arrived, and it has 1x EPS plug that is hard wired to the PSU.

... and it also comes with an EPS modular cable which I can plug into one of the many blue modular ports on the back.

So, technically it has 1x EPS plug. And technically it has 2x EPS plugs. I think this is where the discrepancies on Corsair's website comes from. In any case, it will work nicely for my purposes.

Thank you for the help!

"  ==>   I don't think that's why they have the discrepancy.    I think it's just a disconnect between the technical folks (engineers) and the tech-writers.     A modular supply should (and for all the other types of connections does) list the number of plugs it comes with, INCLUDING those that are connected via modular cables.

In any event, it clearly is going to work for what you need here -- THAT is the important point :-)

Including my own comment in the answer because I summarized the Corsair PSU's and the # of EPS plugs they have
