PSU Connectors

Hi,

its been a few years since I built my last computer, and haven't kept up with some nuances of the latest motherboard and PSU connector compatibility.

e.g.
If I look at the spec of the MSI X99S MPOWER, I see the following:

Internal I/O Connectors
- 1 x 24-pin ATX power connector
- 1 x 8-pin ATX 12V power connector
- 1 x 4-pin ATX 12V power connector
( http://us.msi.com/product/mb/X99S-MPOWER.html#hero-specification )

But if I look at the ASRock Extreme6, I see, as far as I can tell, only
- 1 x 24 pin ATX Power Connector
- 1 x 8 pin 12V Power Connector (Hi-Density Power Connector)
( http://www.asrock.com/mb/Intel/X99%20Extreme6/?cat=Specifications )

i.e. no mention of 1x 4-pin ATX power connector.

Although the latter does list other connectors, and maybe one those connectors corresponds to the same 1x4-pin on the above MSI motherboard.

But then if I look for a review of the MSI X99S MPOWER, and see what PSUs the testers used, I find the following:
OCZ 1250W Gold ZX Series
and
Corsair AX1200i Platinum PSU
( http://www.anandtech.com/show/8978/msi-x99s-mpower-review/4 )

So if I look at each of of those two PSUs, I find they both have 1x 20+4pin ATX, and 2x 4+4pin EPS connectors.

So does one of the 4+4pin EPS connectors fit into the 1x8pin connector of the ASRock Extreme6?

And likewise, does one of the 4+4pin EPS connectors fit into the 1x 8-pin ATX of the MSI X99S MPOWER, and the other 4+4pin EPS fit into the 1x 4-pin ATX on that motherboard?

Am a bit confused by those 4pin, 4+4pin connectors...


So looking at the following PSU: PURE POWER L8 | 530W CM
( http://www.bequiet.com/en/powersupply/249 )

It lists the connectors at the following:
1x ATX-Mainboard (20+4 pin)
0x P8 (CPU)
1x P4+4 (CPU)
0x P4 (CPU)

So I'm thinking this is not compatible with both motherboards above?

Anyone?

Thanks.
