I have a quick question for some hardware early adopters. I'm putting together a new system and I'm a little worried about possible heat/power problems. Below are my specs, any opinions out there to if I may experience a heat or power problem?

CPU: Intel Pentium D 3.0 Processor 830
MOBO: Asus P5ND2-SLI Deluxe
MEM: 2x Corsair XMS2 512MB DDR2
VIDEO: 2X BFG GeForce 7800 GTX OC PCIx SLI
HD: WD RAPTOR 36GB SATA 10,000RPM
HD2: WD 800JB 250GB SATA 7,200RPM
DVD: Pioneer DVD-120S 16X DVD
DVDRW: Sony DRU-700A DVD RW
Soundcard: PCI Creative Labs Audigy
FDD:Generic FDD
Case: Enermax CS-3171 Mid-Tower
Case Fans: 3x 80MM fans 1 back, 1 side, 1 top
PRW: Thermaltake 480W Butterfly Series

So is this doable? I plan on leaving everything at MFG spec not planning on overclocking. My two main concerns are obviously heat and power, but if anybody notices anything else that may be a problem please reply as well.

I would worry about heat, power, and that mobo. Tom's did a stress test with the EE 840. It might be worth a look for you. (most people here think they should have put the 840 out of our misery)
They do not recommend the nforce chipset.

The processor is a problem.

The heat shouldnt be that bad nothing you cant handle. I think it is comparable to the temperature in the desert during the summer.
Sorry im biased.
THG burned all the boards except the intel board. They were trying to favor intel too. Karma.

But then THG also used a stupid PSU <i>and</i> used the wrong HSF. It's quite likely that if they weren't complete idiots things would have gone significantly better.

They used same PSU for AMD, and they also used wrong cooler for AMD.

..but PCP&C PSU is not a stupid PSU i believe. It would be better if they didn't change it to enermax, but to a new but the same type of PCP&C's PSU. ONly if that fail also, should they change it to another brand...

For me the dual core intel proc is good considering that i live at 1700m above the sea level..

So? AMD uses a lot less power than Intel. What works for AMD's dual core obviously blows on Intel's.

Are you serious? I didn't catch that, but then I gave up on them doing anything right fairly early.

Either way though, the point still stands that any idiot can assemble a system with wrong components and have things fail badly. All that it proves is how much of an idiot the reviewers were, not how problematic a platform is. You can crash <i>any</i> platform with the wrong parts.

Yep, they used wrong cooler for X2 also.

The issue was never the PSU. The original one was a 850W model. Now PDs may be extraordinarily powerhungry, but 850W should be enough really They changed the PSU as a "precaution" as they where getting desperate trying to make the 840 system stable.

= The views stated herein are my personal views, and not necessarily the views of my wife. =

imo...

good psu + wrong hsf = all bad
good psu + good mobo + wrong hsf = all bad

they're just so blaming nforce chipset, i don't get it... are there any reviews with 840EE/D and nf4 chipset that could prove thg wrong? i wonder...

I'm not convinced of that. The PSU that they originally used looked like it was designed for servers and most of that wattage wasn't available to the mobo. It's all about the balance and the fine details (such as combined limits), not the total wattage. That was what it looked like at first glance to me anyway. Again, I didn't put much energy into reading that goofy (if not worthless) article as it was pretty clear from the beginning that it was going to be crap.

Pleased to meet you. Hope you guessed my name.
But what's puzzling you is the nature of my game.

Alright. That's just sad. I guess the fan on their wrong HSF had a pretty high RPM. It's amazing how small of a HS you can use if you don't mind a lot of noise! **ROFL**

Maybe THG should stand for Tom's Hardware Goofups. Except that Tom is no longer involved either, so maybe it should be something more like Tally of Hardware Goofups. Or just Totally (incompetent) Hardware Guide.

They're just scaring me more and more every day. I can't even remember the last 'review' that they did that I found useful. To be fair though, maybe that's because I hardly ever read their 'reviews' anymore.

ahh I thought I saw the x2 cooler look different. The cooler looks like the one that came with my 3400+ and my friends sempron 2600+

for the reference, pc power&cooling power supplies are the industry standards, so you can't really get better than that. they have AMPLE power to all voltage rails, including the mobo. i mean, even IF the it wasn't giving enough power to mobo, its 850watts for god sakes.

The funny thing is, they didn't have any problems when the put the wrong hsf in. They only put the wrong hsf in on the last mobo. Before that, they had been using the hsf that came with the chip. Then they got a mobo with 2 hsf units. This was on the last mobo. They picked the smaller, lighter hsf, with fewer fins, rather than the one that was identical to the one Intel gave them with the chip.
The hsf was never the problem.
