1070 SLI pc restarting while gaming

Tbf, is it really worth £100+ in order to run your 1070's overclocked for a few more fps? I'd personally run them at stock and be happy I saved the dosh tbh :D

But then again I run a pair of FTW's for 3440 res so I'm probably overkill :p

Agreed on both counts.3440 sli 1070 is sweet.No oc required.:)
 
I had this exact issue a while back. Dying PSU was the culprit. With a rig like that, invest in a quality PSU. Cheap ones skimp on the components and degrade faster.
 
As stated don't ever skimp on a crap quality PSU. This is most likely the culprit here.

The PSU is the heart of the system. If that goes it could take everything else with it.

I'd certainly agree with what everyone else is saying and get a good quality PSU. 850w or something. If your likely to go SLI again I'd go with 850w at least if not more.

Corsair, EVGA, Superflower, seasonic, antec. All top brands. They can be had reasonably cheap too. Both of these 850w PSU's, under £130.

You guys have got me all paranoid now about the possibility of my PSU dying and taking everything with it!!! Your right ive skimped on my PSU on a rig thats worth about £1500+. Why do PSUs take other parts with it when it dies? Surely theres some kind of protection against this? Even if it's a top brand?

I'll be getting a new PSU sharpish.

When PSUs die there is potential for it to create a massive burst of high voltage current that can fry the circuits of anything and everything connected to them. Bad PSUs are more likely to die and have less protection against this happening. Good PSUs are less likely to die and have protective measures in place to prevent damage to other components.

Thought it would be higher than that. Googling suggested 250W for his cpu alone (v high oc and voltage on that) and his 1070s overclocked can both pull 200 to 250W each.

Just advising that replacing his troublesome psu with one with little head room might not be the best idea for the little bit extra it costs.

Plus, personally I like to stick around two thirds capacity but thats just me. Means the psu isnt ever stressed and the fan ticks over or doesnt even spin when load is down.

I didnt need 1200W in my current system and doubt I am using 500W atm but my psu has lasted 7 years now without skipping a beat and seeing me through 3 different builds including SLI and xfire where i might have peaked at 800 to 900W.

on side note
5930K
980 SLi
was 550W at max load (GPUS)

need to test 1080

That happened to my old Gigabyte Odin 850W PSU, back when I was running a Phenom II 940 Black Edition, and a 4870X2 both heavily overclocked.

PSU went pop, and took the GPU and my waterpump at the same time.

The cheap ones have very little protection circuitry. Components are of a low standard and fail much more catastrophically.

Definitely get a quality PSU as soon as possible. Most important part of your PC. Everything is connected to it. It's not all about the wattage number, the quality of the internals are more important.
 
A friend of mine has just told me some guy is selling a EVGA 1000w G1 Supernova for £100. He said its a unwanted brand new unopened sealed rma replacement. Worth it?

Overclocked and under a proper load? I saw far more than that coming from the wall on a meter with a 5820k and a pair of 980's (not Ti's)

Back on topic should be a big sticky at the top of all the hardware sub forums saying

"DONT SKIMP ON YOU PSU!"

Its a terrible false economy can lead to all sorts of otherwise fairly hard to diagnose problems and at worse a quick way to kill your other hardware
