PC randomly shuts down after I installed new GPU?
So, i recently upgraded from my 650 ti Boost to an ASUS 780 3GB, and now my PC has started to just turn it self off randomly, and then start by itself 5 minutes later. Does anyone have an idea to why this is happening?
Onus said:The GTX780 needs a lot more power. What is the brand and model (not just wattage) of your PSU?
Are there any useful entries in the Windows Event Logs?
Im kinda new to this, I think the PSU may be the problem, I'm curently on Cooler Master B500, 500W PSU. That might be the problem..

Does sound like the power supply is struggling, but run a few tests first:
Use GPUZ (excellent freebie BTW) to check the new card temperature, it may just be something simple like a loose sticker jamming the cooling fan.
Grab a CPU temperature monitor and check its temperatures as well, it's easy to accidentally dislodge the CPU cooler during an upgrade.
For a PSU about 600-650 Watts from a good maker like: Corsair, Seasonic, Silverstone, FSP, Fractal Design, XFX or EVGA will do the trick.
Onus said:Oh yeah, that PSU is insufficient. A good 550W PSU would be enough. CM offers very few PSUs that are good enough, regardless of claimed wattage. Seasonic or one built by them (e.g. XFX) would be a good choice.
Thanks for the help, will an upgrade to Cooler Master G700, 700W PSU be any good? Its at a pretty decent price (especially here in Norway)
Only if that's one of the new Seasonic-built ones, but I thought that was their "V" series. If not, I wouldn't touch it with a ten foot power cord. I couldn't find any reviews, just articles claiming it to be a new, "budget" unit. Based on their history, no thanks.
