I downloaded the Leliana's Song DLC and after playing it for around 20-30 minutes or so my computer will randomly shut down. Is this a problem with the game or with my computer? Dragon Age had always worked fine up until this point.

[Gorath Alpha]

Current system thermal readings are at what levels? Complete description of everything that happens in the "shut down" is also needed.

[Blado123]

When it shuts down it literally just turns off. It doesn't automatically restart or anything; it just shuts off. What is the best program for determining my computer's temperature?

[Blado123]

On speedfan it has fans one through five listed and it says only fan one is moving and that is at a rate of 2885 RPM.

on Coretemp it says core#0 is 54 degrees celsius and core#1 is 51. This is with only firefox up.


Edit: it goes up to the 70s while playing Mount & Blade: Warband, which isn't really taxing on a computer.

Edit2: Yea I think its an overheating problem. It got into the 80s while playing a game.

Power Supply overheating can only be surmised from the rest of the system, but is the type of no-warning stop you described.  If it's an old, or a low quality brand (most of the brands are just that), its output is almost always overstated, which gives them less cushion.  As they get hotter, they get extremely inefficient, and the current they supply falls below what the system requires to operate. 

Even quality brand power supplies deteriorate over time, which is why most system builders like myself overspecify, to have plenty of cushion as the device ages.  After 4-5 years of regular use, a "500 watt" PSU is only producing about 70% of its rated amperage (that's why I have set the watt number in quotes, as that isn't the important thing, the CURRENT is what is important). 

[Blado123]

I recently replaced my PSU, so I would hope its not malfunctioning already, although it isn't a very strong one. After cleaning my computer though, its running at about 40 degrees Celsius, so maybe it was that.

[Gorath Alpha]

Let's have the brand name and model number, and we'll look it up. There are a hundred different brand names, and only about a dozen qualify as decently made, with some ringers even among the lines that carry those 10-12 brand names.

You probably should ennumerate the rest of the system components so we can be sure your 430 was adequate to handle your current hardware, if it is a quality product.

It probably is low quality considering it was cheap. Its a Dynex and the model is DX-400WPS.

Yeah, the rule of thumb isn't to go cheap with a PSU. Also, never take a PSU at face value. It may say 650W on the box for example, but if the 12v rail (essential for providing sufficient power to the GPU) is lacking then it could display behaviour akin to what you're experience.



Go for a more reputable brand such as Corsair when picking a PSU. Gorath probably knows his brands better than I.

[Gorath Alpha]

"Dynex" is a house brand for generic products sold at Best Buy.  There is no generic power supply worth matching up to a Geforce 9800, from ANY producer.  It cannot supply the amperage required.  The quality brands include the following:
Corsair, Enermax, Fortron, PC Power and Cooling, Seasonic, and Sparkle (there are a few more that are out there, but those are the ones that come to mind first.  

The Dynex can be purchased for less than $30; a quality "500 watt" unit will cost at least $50, all the way to about $80.

I'd throw Antec into the mix, unless anyone thinks they're no longer good.



But yeah, gotta agree so far. You've got a heat/resistance/PSU issue. Probably the PSU as Gorath mentioned as the needs of the 9800GT are high.

[mousestalker]

Just a note, I ran across an amazing deal at Best Buy recently. They were marking down the Corsair power supplies for deep discounts. I have no info as to why, but that usually means that they are about to replace them with either another brand or other models from Corsair. I am guessing the latter. You may want to cruise your local computer component stores and see if there are any discounted name brand power supplies available. Stay away from refurbs, what you want are new, but discounted.

Is rocketfish a good company for a power supply unit? And what is the best Watt power to go with for my computer? And how about thermal take?

[Gorath Alpha]

Rocketfish is a similar re-mark brand name, similar to the way Dynex is what Best Buy has added to otherwise generic parts. If you know what you are doing, and can examine something such as a PSU with an expert's eye, only then can you take the gamble on such brands.

Not that long ago, there were LianLi PC cases up for sale at well below the usual LianLi prices, and the brand they carried was "Rocketfish". I named the brands that came to my mind already. Most of the lines that are being offered by Antec right now (see their web site) are from Channel Well, and worth buying.

[Blado123]

I'm replacing my computer in december. Which one will better suit me for the price until then,

http://corsair.price...num=CMPSU-550VX ?

or http://corsair.price...num=CMPSU-450VX ?

edit:  or this one?   http://www.newegg.co...N82E16817139018

The last one, at Newegg, with the rebate, is the best value of the three.
