PC just reboots when gaming with new graphics card?

Mattmeow · Nov 15, 2015

Hi, I just installed a new graphics card, I upgraded from an MSI R7 250x to a EVGA GTX 770 that a friend gave to me. Unfortunately, when I start gaming usually within the first 5 minutes the pc just shuts off by itself and reboots. But when I'm not gaming, for example watching YouTube videos, using the internet etc. it works perfectly. I've already tried underclocking, but nothing worked. I looked up my psu and it only had a 3 star rating on newegg, here is a link : http://goo.gl/KH8D6k
Also here are my PC specs

GTX 770
Intel Core i3 2130 3.4 GHZ
LOGISYS PS575XBK 575W ATX12V SLI Ready Power Supply
1TB Hard Drive
8 Gigabytes of ram
Windows 7 Ultimate 64 Bit

Do I have to get a new power supply, or what is the issue?

How does it reboot? like when ur gaming does it shut off completely with a black screen or does it go through the normal reboot logo and then restarts?

If it goes through the restarting logo thats a windows related issue reinstalling should fix it if it shuts off completely then might be faulty psu.But i dont see why wouldnt your psu hold that card the wattage is fine for what you have.

Your PSU is very low quality and highly unlikely to meet its rating while being a failure waiting to happen. I think its highly likely to be the problem but even if its not it needs changing before it fries your system

you could be running into some power shortage issues so thats why the system restarts. id recommend you swap out the PSU for an Antec 650w or something corsair

EVGA makes pretty good an cheap power supplies. they are recommend by linustechtips but my personal prefrence is antec

I just bought it before I read your post. It should be coming in 3 days. I'll let you know how everything goes once i've installed it.

I've also discovered that the psu was making a really weird noise when I turned on a game and i could see light flashing in the power supply, it was weird. Hopefully this is new power supply fixes the issue
