PC Restarting - Mainly when gaming

Gimpymoo · 29 Jun 2009 at 21:31

I think my PSU maybe the culprit.

AMD 720BE 2.8Ghz Tri-Core
AMD 4850 512MB
6 x HDD'S

OEM PSU = 400W

Now, is that uber under spec?

Never had that problem before, been running the rig since feb.

I am only using the stock CPU fan with limited case cooling.

CPU at 60 degrees under load, this shouldn't force a restart should it?

So, what you think, CPU fan or have I beat my 12v rail into submission - lol

I agree its most liely the psu. Have you had a look to see how your rails are when under load? You can use speedfan to graph the 12v rail while gaming and have a look when you finish to see if its dropped. If it has its a sure sign of an overloaded PSU.

Good idea.

Will run it on the second screen while gaming and see what happens, thanks.

OK, Speedfan logs the lowest value to be 11.52v. Obviously, I assume it is unable to log the exact voltage at the moment is restarts.

It averages between 11.65v - 11.71v.

Is 11.52v considered low?

Would that be a good buy?

I quiet fancy a modular PSU though and these seem the best Value/Performing ones I can find although is my thinking flawed and a none modular one is just as good?

At the moment, the 700w is only £4 more than the 600w although it is £15 MORE than the 500w although I feel the 500w would not give much headroom for future upgrades.

Mmmm... Appears to have slightly better build quality/Components than the OCZ one...

Conflicting reviews though:

The cables are as have been said, quite long so fitting un used cables in a 'smaller' case can crowd the components slightly.

No bells and whistles on this PSU but it does its job and quietly. Note although the cables are long I found fitting in a large case (Antec 1200) to be problematic as a few of the cables only just reached.

LOL

The Seasonics look nice but would prefer a little more juice than 500w, if only for Future VGA/CPU upgrade.

Mmmmm.. My 2nd core is getting 10 degrees hotter than the first, taking it over the maximum 73 degrees recommended by AMD.
