PSU Causing hardware problems?

I have had some issues with a new i7 build recently, the mobo I was using was BSOD'ing a lot and the LAN controller was refusing to initialise unless under very specific circumstances (see this thread for info).

My question is, could a lack of enough stable power cause problems like those?

The spec is as follows:
Gigabyte EX58-UD5
6 Gig (3x2) OCZ 1600MHz Gold
i7 920
BFG Geforce 295GTX

I'm running all that on a Corsair TX 750W PSU.

I have used this calculator to work out how much power the setup should be drawing and its pretty close to the 750 rating of my current PSU.

So... would this be likely to cause the kind of problems that I have been experiencing or should I be looking elsewhere?

Edit: I have 4 SATA drives @7200rpm, a DVD drive and the case is an Antec 1200 (7 case fans total).
 
Unless your PSU is faulty then it won't be the issue. As that would easily power your setup, that site is covering it's back with the requirements. You should be able to run that system comfortably on a good 650W to make you feel better :)

Its possible there is no fault, are you OC'ing at all? If so you should try defaults. One thing Id say is check what speed the RAM is running at in BIOS, the 920 isnt meant to handle RAM that fast, so underclocking the RAM may help.
In fact just read your other post, its the RAM, its not the board lacking support its the CPU, due to the way the i7's work, RAM support is controlled by the CPU, and neither the 920 nor 940 support any faster than 1066 atm, only the 965 which is silly expensive. Though what you can do is underclock and use the headroom to tighten up your timings
 
No overclocking at all, I couldn't even get the rig to work stock so never got to the point of trying overclocking. Also, the RAM was running at the default 1066 that the 920 is capable of. No issues from that there I would think.
 
Yeah, the memory BSOD'd when I set it to what it was rated at.

The problem I was more concerned with was the initialisation of the LAN failing unless I discharged the capacitors on the board before every time I booted it (including restarts)

That's bullsh*t calculator.
350W should be very close to max draw.


Would you trust to anything what some magazine says about some product like car if half of magazine's pages where ads of it?
Then why to trust to some page with equally big conflicts of interest?
 
I wasn't taking it as gospel truth EsaT, I was just trying to figure out what might be the cause of my problems with this board... It was a suggestion, that's all.

Do you have anything better to add?
 
Having fully read your other thread I see you were awaiting an RMA, have you got a new board yet or not?
Sounds like youve been unlucky because by all accounts the UD5 is a great board
 
Yeah, the board is being returned no fault found as of today. This is after a second re-test under the exact conditions that I specified were causing the problems for me (any time when the board had been powered, turned off and then straight back on again or rebooted) and they could not get it to reproduce the problem.
