Computer Restarting When In Game; PSU Issue?

[icanhascpu2]

Computer is stable until I load a game. Game being a 3D game, Skyrim, Crysis, GW2, Wow, etc. Sometimes it plays a few min, sometime it will restart upon the first second of rendering. CPU is Athlon II 240 not overclocked. GPU is a 460GTX (came slightly overclocked by manufacturer, but I under-clocked it to stock with nvidia inspector). PSU says 450w. It had one 6pin (needed 2) and I have another that converts 2 5v to the second 6pin. Is something being overloaded? What is possibly happening, and what can I do to fix it or what do I need to know when I look for a replacement PSU?

The PSU came with the case? Yes, likely replacing it will cure the rebooting problem. Before you do that, however, get some monitoring software that does logging (Speedfan for CPU and MSI Afterburner for GPU) to make sure it isn't an overheating problem.

 

[icanhascpu2]

Thanks for the reply.

I have nVidia Inspector for the GPU, and had set the fan at 100%, temps in the low 60s. My old car did this as well unless I underclocked it, so I am pretty sure its not the GPU. CoreTEMP is reporting 45 for the CPU. Pretty cool I think. The PSU I bought maybe 6 years ago separate, plus I was reading up that some of these share rails and the fact that the GPU only has one 6pin PCIe line and had to use a converter for the other from two 5v lines tell me maybe when my hard drive tries to access at the same time the game is loading and sucking power from the 6pin+6pinconverter it overwhelms the rail?

Does this sound right?

Reguardless I guess Im looking for a new PSU, but Im not sure what to look for so I make sure this doesn't happen again.

New PSU is the answer

New PSU is the answer

Yes, but this doesnt tell me what to look for. 450w is enough to power my machine, so its something else I need to make sure I look for when getting a new PSU. Ill be going 500w min this round, but thats just one part of it. Do I need to make sure of certain things so my GPU doesnt somehow overwhelm a rail? What do I look for to make sure of that?? Or will 2x 6pin PCIe lines/rails (what do you call them?) be enough to look for?

Thanks dudes

A quality 450-550w unit would be fine. Pick a seasonic model and you will be assured its good quality. Note that seasonic makes PSU's for man other PSU sellers, XFX brand is probably the cheapest way to get a seasonic made PSU. I always buy single rail PSU's to take overloading one rail out of the equation, keeps it simple.

 

[icanhascpu2]

Thank you I will keep it in mind!

$55 - ($20) MIR = $35
corsair builder should be good enough
the cx500 is actually cheaper than the cx430 atm

My GTX 460 is running off a Seasonic-built Corsair 520HX, which is plenty of power.

Don't sweat the whole single-rail/multi-rail thing too much. Here's a write-up from JohnnyGURU, who has worked in the PSU industry and done numerous PSU reviews.

You need a new psu regardless.

No, this one is working, I just have to underclock the GPU to keep it stable. I could keep on like this and get work done and play games at 80% potential fps, but I rather not

Was actually looking at that one, reading the reviews several days ago. It seems like it works great, then just up and dies on people that have owned it for more than several months. Also a lot of DoAs. So kinda pushed me away from that one. The price is good though!

That one has a shit-ton of good reviews, I will consider it, and thanks for the link!

The +12V rails on that unit are only rated for 15A and 17A, or 180W and 204W, respectively. That doesn't mean the total +12V is the sum of those, usually the total +12V rating is lower. And given that it is an XClio unit, these ratings aren't necessarily to be trusted.

Even if downclocking the GPU might stabilise it, you'd still be running a crappy PSU and stressing it near its maximum capabilities. I'd recommend upgrading to Rosewill Capstone 450W $56 AP. It has 37A or 444W on the +12V.
