  • P5Q Deluxe Desktop Motherboard - Intel P45 Chipset (ATX - Socket T LGA-775 - 1600 MHz, 1333 MHz, 1066 MHz, 800 MHz FSB - 16 GB DDR2 SDRAM - Ultra ATA/133 ATA-7 - 7.1 Channel Audio)


Our Score:


Asus has done its best to cover all the bases by using Intel's new P45 chipset in an extensive range of motherboards. The basic P5Q has a single graphics slot, The P5Q Pro adds a second graphics slot for CrossFire and the P5Q-E adds eSATA and a second Gigabit port. Moving up the product range we have the P5Q Deluxe that we're reviewing this week which is effectively a Pro with a third PCI Express graphics slot, then there's a DDR3 Wi-Fi version and finally we have the Republic of Gamers Maximus II Formula that we'll be reviewing very soon.

The P5Q Deluxe sits squarely in the middle of that list and supplies a fair number of bells and whistles without going ridiculously over the top. It has a certain amount in common with the MSI P45 Diamond that we reviewed a couple of weeks ago

including the P45 chipset, the passive cooling system, a stack of SATA ports, HD audio and one eSATA port on the I/O panel.

Asus has added a third long PCI Express graphics slot but we're not really in the realms of CrossFireX here. The P45 chipset supplies 16 lanes of PCI Express 2.0 to a single graphics slot or splits it eight and eight if you use two graphics cards in CrossFire. That's pretty much the limit of the chipset's abilities and if you plug in a third graphics card you'll get a maximum of four lanes so we'd strongly advise you to treat the third slot as something of a gimmick.

The layout of the board is very tidy with only one possible cause for complaint as the six SATA connectors on the ICH10R Southbridge have been crammed in higgledy piggledy. Two of the ports are laid down while the remaining four stand vertically which is a shame as some judicious movement of the floppy connector would have created enough space to pretty the thing up. Moreover, dare we suggest that the time has come to ditch the venerable floppy connector? We do. You can update the BIOS from a USB key with ease so we feel that the need for a floppy drive has passed.

The area around the CPU socket is remarkably neat despite Asus having to find accommodation for a prodigious amount of hardware as Asus is making use of 16-phase power for the first time. When the demand for power is low the P5Q Deluxe uses four phases and as the load increases and efficiency drops the system switches over to the full 16-phases. The business of power regulation and efficiency has received a huge amount of attention from Asus, Gigabyte and MSI and lies at the heart of a dispute between Asus and Gigabyte over their rival technologies, so we're in thorny territory here.

Good Review - I am very interested in this board for the storage capacity as I have run out of SATA port on my current media server. With my 2port PCI-E card installed I can have 9 hard drives and an optical drive in the same system - plus extra on the e-sata.

Point of note is that the Red sata ports are all on the P45 ICH10R southbridge (which is specc'ed at 6 max and has its own RAID configs). A Marvel controller provides the e-sata and IDE ports and finally a Silicon Image controller provides the additional 2 Orange sata ports. Therefore not all drives will be available in the same RAID set.

Also note the gigabit ethernet ports (one on PCI-E and one on bottlenecked PCI) are both Marvel controlled too - which is different to previous Asus boards I have used where one port was on the Intel southbridge.

I don't think the additional graphics port is totally useless - can't it be used by non-gaming multi-monitor freaks..?

If not then there is no reason a pci-e x1 card can't be used - especially if you want to space out your cards for better airflow....

Do you plan on re-testing the board once a better BIOS is available..?

Those screenshots show the guy with the amazing overclock was using a different motherboard - Asus P5Q Deluxe WIFI-AP edition - that supports DDR3 ram. Does this explain why he was able to take his FSB significantly higher than a DDR2 based board that proved not to be too flexible regarding memory settings?

Also, your review was apparently of the MSI P45 Platinum edition, not the more expensive Diamond, which (like the more expensive Asus board mentioned above) also features support for DDR3 ram.

I agree about the third PCI-Express slot. It's less than useless if it means the 16 lanes result in even less bandwidth going to the main GPU. If you could maybe run each slot with independent lane assignment then fine, perhaps a very small minority would find it useful.

Is it true the MSI board still offers the best overall performance and reliability? I hope so, as I've ordered one in preference to the ASUS models since they appear to be extremely finicky and more than a little troublesome to operate. Oh lastly, a lot of people still use XP for gaming systems and the use of a floppy disk drive to load SATA/RAID drivers during Windows installation is essential. It's the reason I'm having to change my motherboard as the damn header appears to be missing a pin so no attached floppy drive is recognised. I'll know for sure if that's the cause when the new board arrives.

Cheers for the reviews. Perhaps, akin to the power supply round up and technical explanation into their operation, something could be done to explain the ins and outs of motherboards more thoroughly? Maybe not though, on second thoughts as they have enough features already I guess. Such a wide range of choice though - it's definitely a headache choosing one that's for sure.

i may get this as my current motherboard is limiting my computer's power
