Asus P5N-T Deluxe 780i Motherboard

The board - a close-up

Asus P5N-T Deluxe - a close up
The Asus P5N-T Deluxe is again a well laid out and well thought out board from Asus. It seems boards nowadays have less and less of the niggles that we used to see, and didn't want to, and have more and more of the features that we do want to see. As on the P5E3, there are no waterblocks (a good thing in my opinion) and again we see a large heatsink configuration on the board.
100% solid conductive polymer capacitors are used throughout the board and Asus have again used their excellent 8-phase power management.

The black PCB is again used by Asus and you cannot complain about that. The colour layout of the board is again easy to use and clear, although I would have liked to see just blue, white and black used as in some of Asus's better looking boards. Again though, Asus have put some nice design ideas in there with flipped 90° SATA connecters and everything close onto the edge of the board. The only thing different to the P5E3 in this respect is the lack of 90° flipped IDE connector, but I guess this isn't a real big issue.
I would also have liked to see some sort of onboard power and reset buttons and a POST readout LED of some description, although those sort of things tend to be restricted to Asus's RoG boards.
cpu area  cpu area 2
The CPU area isn't as packed as that of the P5E3 and the right-hand PWMs only have a heatsink on, not plugged into the heatpipe cooling system. As usual, Asus have supplied a fan to go over the top heatsink in the heatpipe array, although you should not need this if you have decent airflow and a fan on your CPU cooler that can cool them. There's also plenty of room for manouvering with a large cooler and the Noctua I installed on the board went on without a hitch.
RAM area 1  ram and cooler area
The RAM area is kitted out with all of the connectors at the side, although the IDE connector has a particularly bad position which could be hard to get to as the main ATX 24PIN cable is right in front of it. This is the worst niggle on the board and could be a bit of a hassle. On the upside, the RAM slots are easily far enough away from the CPU socket to make sure you should be able to install any RAM there and not have to worry about clearance.
Asus have again used their stack-cool PCB feature to make sure that the heat goes away from the problem areas and have also added an extra heatsink on the edge of the board to make sure that the PWMs get cooled effectively.
PCI layout
The place where the board really steps up is in the PCI-e department. With 3 x PCI-e 2.0 slots, you can put 3 x high-end graphics cards in there and have yourself an SLI monster. Asus have also supplied an extra-long SLI connector to make sure that you use the two blue slots for SLI, which is good as it also frees up the PCI slot for use with that all-important sound or physics card.
Here you can again see the general layout of the board is pretty good, although as I have stated previously, it would have been nice to see a Power/Reset switch and perhaps an LED POST readout.
Overall the P5N-T has a few niggles but doesn't do too badly for board layout.

We check Asus latest 780i board

See how it does

15-01-2008, 14:32:40

Good review, shame about the board..

What a stupid idea to stick a IDE connector in front of the ATX connector though =/

15-01-2008, 14:44:52

i was thinking that, terrible...

the chipset doesnt seem the best ever either...

Nvidia have failed every time after the Nforce 4 chipset..

15-01-2008, 15:13:49

nForce 4 ftw!

Great review, although lacking board.

15-01-2008, 15:15:42

Asus are writing a new BIOS after reading about the issues in this review so hopefully we can revisit it and perhaps it will show some better potential

Thanks for the comments

15-01-2008, 16:29:36

Very nice review, but the board just under 680i I think, like Kempez said hope the new BIOS help.

I love that... Thats seriously taking customers feedback into consideration!!

Nice one on the review anyway Matt.. Shame ya didn't have more to work with. Hope that 790i will be better.

17-01-2008, 08:09:27

i am only waiting for the new mobo 780i to buy a new pc. Such a shame that asus didn't make it, else i would go and buy it now. Now i have to wait even longer. Hope better ones will come out soon

17-01-2008, 08:12:36

Do you need SLI? The Intel X48's should be starting to make an appearance shortly, and I'm betting they'll provide better performance than the Nvidia 780i. However, it will be interesting to see if ASUS' new BIOS rectifies this board's issues.

Do we have any idea on roughly when the X48's will be about.. Next month or two?

17-01-2008, 09:26:18

Well Gigabyte has officially launched their X48 range (GA-X48T-DQ6, GA-X48-DQ6, GA-X48-DS5) so I can't imagine that it will be very long before ASUS and other manufacturers have them on the shelves.

17-01-2008, 10:21:27

I was thinking about SLI, maybe buy an other 8800 GT when the price drops, so i was thinking about the 780i, or 790i maybe. It's painful to wait an other 15 days or so, to see the new stuff. And to buy a mobo that needs a bios update so soon doesn't seem like a good idea.

17-01-2008, 17:36:26

Try a Striker II?

17-01-2008, 19:11:43

Tbh 790i is becoming to appear more appealing to me. DDR3 is becoming much better value.

Check this out. DDR3, 2x 1gb rated at 1600mhz at "just" 140 is pre-ordered, getting much better value.

Pretty soon it'll be overtaking DDR2 withe the 790i's and X48 releases.

17-01-2008, 20:44:02

only diff between 780i/790i and x38/x48 is the support of DDR3?

Then i would buy now.. No diff between DDR2/3, well not worth the cost

18-01-2008, 10:09:00

Well as you said it's one of the most expensive mobos till now. I think it's a bit too much to give for a mobo for me and also i don't see many other mobos in the market, so i think its better to wait maybe 15 more days and then deside...

18-01-2008, 10:25:24

There is also the EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX that is out, and as i can see, users are more satisfied with this mobo. Maybe you will test it out later, but thanks to everyone for your help and thoughts !

19-01-2008, 10:19:23

Hi Guys, I am a complete newb to overclocking, I have built several systems but never delved into the Dark Art...! (Not with any success anyway!)

I bought this Mobo as I got fed up of waiting for the Striker II Formula to appear at scan despite having pre ordered it ages ago.

I am really struggling to get anywhere with it, I am quite pleased with the stock performance (compared to my ageing AMD FX 55, A8N Sli Deluxe combo) but would appreciate some tips / BOIS settings to help me get going. The best I have done so far is get a 10% increase with Asus' AI overclock setting in the BIOS if I try to adjust things manually it wont POST....


Great Site by the way.....

Cheers, Dave Warry.

19-01-2008, 10:29:14

I'd suggest updating to the latest BIOS before you even try overclocking.

Set the CPU volts a little higher and al;so set the CPU VTT a little higher

19-01-2008, 12:19:27

Thanks for the quick reply, I have updated to the latest BIOS (0502) and tweaked the voltages slightly but I am worried about frying stuff...! I am unsure what voltages are reasonable for the various settings. Is there a list of the voltages and tweaks that were used in the review of this board?

I will crack it, I just need to get over the initial fears....!

Cheers, D W

Hey guys, Asus have released a new BIOS for the P5N-T Deluxe Nforce 780i. 0602.

I have used Asus, AI overclock option and got it up to 20% overclock with no problems this means a FSB of 320mhz and a core speed of 2.88ghz, I know that this is peanuts but previously the board wouldn't POST with an overclock of 10%...!

I now need to try adjusting the settings manually but could do with some advice on what voltage adjustments should be safe, or do I leave the voltage settings on "Auto"

It would be interesting to see what an expert Overclocker could get from this board with the new BIOS, seeing as the performance was "lacking" during its review...!

ANY advice would be very gratefully received....Cheers Guys


21-01-2008, 14:16:35

Remember overclocking is based on a chip per chip basis so no one person will get the exact same results

Anyone can become a good overclocker, it just takes patience and research mate and a lot of trying again.

Stay whithin safe CPU voltages (1.55v for air cooling for example) and watch the temps alla round

21-01-2008, 14:30:44

Cheers Mate,

I will try and push the FSB up slowly, my target is 3.0ghz (unless I get hooked and start watercooling etc...!). My RAM is rated at 1000mhz so that shouldn't pose a problem.

You mentioned the CPU VTT voltage in your last reply, what would be a safe limit for this setting?

Cheers, D W

21-01-2008, 15:06:03

Only bump up CPU VTT if you get stuck, do it in small increments

24-01-2008, 13:07:25

Now that there is a new bios update for this mobo, did it become any better, and how about the overclocking, can it reach 3.0Ghz with the build in cooler ?

24-01-2008, 15:35:06

I was waiting for the BIOS release to try again but due to review time constraints I've had to take it out.

I may get some time to try again but it won't be for a while

24-01-2008, 15:38:06

I managed to get it up to 3.375gig (FSB of 1500 in BIOS) and I could run 3Dmark 06 comfortably with a score of 19,448. However when I was playing stalker all maxed out it threw up BSOD's after about half an hour. I didn't try to push it any more than this and this was with my Thermaltake Big Typ 120 air cooler turned right down to silent levels. I am now running at 3.038gig (FSB 1350 in BIOS) with all the fans on Silent and it is Solid as a rock, (No problems playing Crysis last night for 3 hours, wife is at work...!, with all the settings at HIGH inc. AA & AF, Res 1600x1050 on 22" screen) 3Dmark score is still over 1700, So I personally am well impressed with the new BIOS it has helped me overcome my NewB overclocking fears....!

It would be good to see what an expert OC'er could do.....HINT HINT.....!

Cheers, DW

24-01-2008, 15:43:58

I simply don't have time right now. If I get some (unlikely) I will update the review

24-01-2008, 16:41:10

Thanks dood, you can only try :-)

02-02-2008, 07:34:50

I think the benchmarks would be better, if a Nvidia card was used on a sli board. using an ati card makes no sense to me. very bad review.

The fact that nvidia and ATI cards perform nigh on identically on any chipset not crossed your mind?

Also the ATI card was used on other boards review, so it there as a control. Using an 8800GT vs the X1950 pro and then saying the motherboard is fantastic for gaming isnt exactly a fair test is it.

And intel dont make graphics cards to test with intel chips.

02-02-2008, 09:44:56

That`s the thing. There are a fair few reviewers out there that would switch out cards, cpus or memory, but where is the fairness in the comparison ? Or the consistancy really.

U have to try and keep the playing field for all the boards ur going to compare as even as possible. Components, to an extent don`t matter that much as long as they`re the same. A choice of decent proven stuff in this case I think, don`t want to overcomplicate things either and take ur eye of what ur really reviewing, which is the mobo.

06-02-2008, 15:39:58

Not a bad review, definitely not a "very" bad review. There are many benchmarks that were taken that don't rely on video at all. I do agree to an extent about the video card, but mainly because it wasn't tested with a PCIe 2.0 card, which is what the board is supposed to be for.

I'm sure it's quite hard to keep everything accurate because, for instance, in a lot of benchmarks a 8800 with 256bit memory vs. one with a 345bit (or whatever it is) doesn't look like much now, but once games, etc. utilize it better, there will be a growing difference between the two. Same with the wolfdale vs. conroe, because the wolfdale is using new instructions, and once those are used in apps, there will be more of a difference.

Would really like to see a comparison between PCIe 2.0 and 1.0(1) performance on this site.

17-02-2009, 05:50:39

I bought this board, sadly jumped into it without reading any reviews, i've been planning on overclocking my cpu for ages now, i've read many guides on overclocking (including the ones on here) but i'm still clueless, does anyone know this board well who could help me please?

17-02-2009, 10:58:51

Probably best asking in the overclocking section m8.
