General Problem

Hey everyone,

Basically, my computer keeps either crashing or the lagging really badly when just using windows. I also have problems with crashing during games.

My specs are:

i5 2500k (it was overclocked to 4.3GHz but due to the crashing I put it back to 3.3GHz)
8GB Ram
60GB Intel 330 SSD
GeForce GTX 460 1GB (Gigabyte)

and I had a second EVGA 460 plugged in as well, but I've decided to remove this as I'm wondering whether it's crashing due to too much power being drawn.

I currently have a BeQuiet Pure Power L7 530W '80 Plus' power supply and I'm thinking that perhaps I could do with a more powerful one...I don't really know!

My CPU has an H50 cooling it, and gets up to 50C occasionally, but mostly rests around 35C. The GPUs get up to about 50-60C when gaming but idle at about 30-35C.

Any advice on this would be greatly appreciated - I want to punch my PC!

Thanks,
dirtychinchilla

Are you still having problems, now that you have removed one of the 460`s?

Yup just had a crash right now...

According to this review you need a 650-700W Psu for 460sli.

You could try using onboard graphics. If it still crashes in windows, would rule out the 460s as the problem.
Might also want to try with the other 460 on its own.
Have you added any hardware/software prior to this happening?

what o/s are you using ?

have you tried running with just a single memory stick in ?

gfx card in different pci-e slots ?

tried resetting the bios to default after your overclocking.

what temps the processor running at ?

Btw, how long have you been running sli with that Psu?

fault finding 101, all components out then replace 1 by one and test to death until you find the change that causes the crash.

I would personnel start at stock clocks 1 ram stick with onboard graphics

I remember spec'ing that L7 PSU back in the day. It came to light that it doesn't actually put out 530W, it was closer to 430W if I recall. There was a thread on it but it was a very long time ago.

If you want to SLI the 460 you need a new PSU

Maybe not the one you were thinking of but it'll do: What sort of spec for my brother

FYI for anyone considering the BeQuiet Pure Power L7 530W '80 Plus' Power Supply.

Custom PC have just had one of their big PSU tests.

The BeQuiet has two 12V rails with a quoted maximum combined output of 35A.

In the test the maximum combined output they could draw from 12V rails was 28.5A so they weren't impressed.

Possibly a bad sample but it doesn't look good.

35A would equal 420W on the 12V rails.

28.5A = 342W.
