I see a PLX Chip on the Deluxe, although I can't make out the IC's numbers so I don't know which KIND of PLX chip it is...
Still, it would make sense to me to include one, as the Asus Deluxe and Premium variants almost always support more-than-2-way X-Fire/SLI (and I don't mean X8/X4/X4 because that's kinda pointless). I would expect them to at least offer x16/x16 or x16/x8/x8 or even x8/x8/x8 via PLX, and then reserve 4-Way with either full x16 or with 16x/x8/x16 3-way + x16/x8/x8/x8 4-way multi-GPU setups.
Power delivery looks good, especially on the higher-end "mainstream" boards. They seem to still be using the same VRM/Phase layout that they began en-mass with the Rampage IV Extreme, and as I know how well it works on that board with a CPU that's nearing the 300W mark, I imagine it'll work extremely well with CPU's that draw ~35-45% the power.
I do wish we would start seeing MORE phases for the RAM and PCI-Express, as currently we're pretty well set with CPU Phases (owning a GA-Z77X-UP7 with its 32-phase CPU VRM's that don't get more than warm to the touch even with all the switching frequencies cranked, and my 3770K @ 5.2Ghz with 1.3525v, ~1.2125v for VTT/VCCSA, as well as ~1.7425v vDIMM for 2x4GB G.Skill Trident-X 2400 9-11-11 @ 2740 10-12-10-31 1T, and an MSI G680 Lightning w unlocked voltages running 1438core/7568mem with +195 Power Percent, +84mV Core, +10mV VRAM, +10mV Aux Voltage).
The reason I say this is because with X79, for example, some of us are hesitant to run 8x DIMM's due to the negative effects it has on overclocking, while others have a difficult time overclocking their memory past 2133 or even 1866. I realize that a lot comes down to the chips' IMC, but it's practically a "rule" that Cleaner Voltage/Power Deliver = Less Total Voltage Required and Less Excess Heat due to more efficient regulation.
A real easy example of this is hooking something up to a wall socket directly vs using a top-notch Surge Suppressor with Voltage Regulation and EMI/RFI filtration such as the Tripp-Lite ISOBar Ultra series (which also have isolated filter banks, huge capacitors, and don't use MOV's for anything except secondary, sacrificial volt-stoppers so they can be blown but the unit is still perfectly fine). I run these exclusively, and don't trust any other "surge suppressor" unit after having had the transformer box in my front yard suffer a direct lightning strike; my entire home theater, 6 PC's, family room TV/surround sound, etc were all hooked up to ISOBar 4/6/8/12 Ultra's or the ISOBar Home Theater version (which has angled outlets and 2x Cable + 3x/ea Ethernet and Phone to ensure all connections going into any of the electronics have a common ground). I lost 2 of the ISOBar units, but didn't have a single damaged piece of equipment, which is good because I know that my insurance wouldn't pay for all of the high-end audio gear I've got (Sonus Faber Cremona Auditor speakers, McIntosh Amps, etc) or my gaming/benching or workstation (audio editing/mixing) computers.
Anyway, I simply used some Kill-A-Watt meters and measured one of my receivers ( ) while playing the same WAV song file that is 5:42s long and 239MB in size and about 750KB/sec (a Sigur Ros song), from my HTPC* at the same exact settings/volumes through the same amplifier (one of my McIntosh MC452 2ch 450W-per-Channel amps, also tried with one of my Audio Research DS450 2ch 450W/ch Amps with the same results) and with the same speakers (Sonus Faber Cremona Amati Anniversary Limited-Edition/Hand-Made Italian Floor-standing Speakers, also tried with B&W Signature 805's, Sonus Faber Cremona Auditors/Auditor M's and the floor-standing Cremona's).
The results were:
(McIntosh MC452 450Wx2 Amp + Sonus Faber Amati Anniversary Speakers)
WALL PLUG = 1203Watts
ISOBar4Ultra = 1148Watts from Wall, 1031Watts from IsoBar4Ultra-to-Receiver (KaW attached to both the wall and another to the Isobar4 between it and the receiver plug)
That's far from conclusive, and I know it's not the same thing at all as what goes on in a motherboard's conversion process for power, but it still would make sense that "clean in = cleaner out".
I hooked up the EZ_Plug2 on my RIVE (the 4-Pin FDD Power Plug), which is advertised for use with 8x DIMM's, and found that my memory was stable with lower voltage AND LLC settings at any given overclock.... and that I could tighten timings further than I could previously at any given speed, i.e. from DDR3-2248 9-11-10-28 1T to DDR3-2248 9-10-9-26 1T, or from DDR3-2496 10-12-11-30 1T to DDR3-2496 9-11-10-29 1T.
The same goes for the EZ_Plug1, which is a 6-Pin PCI-Express Power Plug on the board for additional voltage to the PCI-e bus, advertised as only being used when 4 or maybe 3 GPU's are running in SLI/CF-X. While I just have one card in the rig ATM, I plugged it in and found that my 670FTW 2GB, which was at 1348core/7362mem, would go to 1401core/7454mem with no other changes (both are with the voltage at 1.218v).
That tells me that additional 12V power inputs, other than the standard ATX 24pin and 4-/8-pin EPS plugs would likely be of quite some benefit to those of us running fast memory and/or high GPU clocks.
What if all boards had a 24pin ATX + 2x 8pin EPS *AND* 2x PCI-e 6-/8-pin Power Plugs or 4x SATA 12V Power plugs on them, with the PCI-e/SATA Power being sent directly to the RAM, PCI-Express Lanes, and onboard chipsets such as the SATA/USB controllers and LAN chips?
What if my board had 8 RAM Power Phases instead of 2? Or what if it had 4 or even 8 PCI-Express power phases?
Would that not result in far more even power distribution, prevent overloading of any single circuit, and also supply the cleanest possible power with the least possible voltage fluctuation/ripple?
Why don't motherboard manufacturers do this????
