Hi everyone

I am having a problem with my 970 SLI setup. I recently bought second 970 g1 gaming and everything was working fine for around 3 days until last night when I encountered some blue screens while browsing internet I was thinking that it was due to the latest drivers that I have installed. I have reinstalled windows today and installed older driver and the problem with blue screens was fixed but the screen was freezing after around 20 second after bootup and then i decided to get rid of the second 970 so i unplugged and everything is back to normal now.

So my question is whether the RM650 is too crappy quality for 970 sli or not enough power ?

Also since it was running for a few days and now it freezes the screen does it mean that I have damaged my corsair PSU ? For the past few days i was playing games and doing everything as usual...

This RM650 was quite expensive I paid around £100 for it around 4 weeks ago.

My rig is quite new i bought everything new last month

rig config:

i7 6700k
asys z170 pro gaming
kingston hyperX ddr 4 2800 2x8gb ram
corsair RM650
nzxt h440
asus xonar stx
2x corsair SP120 fans with coolermaster evo 212
1 additional 120mm fan on the top of my case

best regards

Hmmm...

Well, looking at it, the GTX 970 pulls about 150w each, and the 6700k pulls 75-80w, that's about 380ish. Motherboard and other incidentals would be MAYBE another 75-100w putting you at 480w with everything running full tilt. That's only about 70-75% load.

The Corsair RM series is a Tier 3 PSU, which means it's 'ok', but not the best.

What I would do:

Take out your original GTX 970 and put in the second one you got. Stress test that one and see if it's an issue with the GPU. If it fails / BSODs / freezes up then you send back the GPU. If it doesn't then the only other issue would probably be the PSU.

I would pick out a PSU from Tier 1 or Tier 2 off the PSU list of a 750w capacity (to give you a little more headroom)...

If that doesn't work, then it could be a motherboard issue having to do with the physical slot, but we'll cross that bridge if we get to it.
