Hi everyone! I hope you are staying safe and healthy
Until today, I was using my Cooler Master B700 V2 (RS-700-ACAB-B1) to power up the following system:
Intel Xeon E3-1245 v2 (close to i7-3770)
16Gb HyperX Fury DDR3 1600MHz
Gigabyte GeForce GTX 980 G1
Asus B75M-A motherboard
3 HDDs, 1 SSD
Things were rather smooth, I had nothing to complain about, until I tried to upgrade to GTX 1080 Ti GameRock by Palit
The system started, but there was no video signal from the video card. I was able to get into the BIOS once after I switched off all my SATA devices, so I tried to re-plug the video card, check if I connected it properly - all in vain. When I tried to re-plug my SATA devices and use my CPU's graphics to get into the OS, I was able to do it but the 1080 Ti was not showing in the device manager.
I tried plugging the video card into my friend's PC with a be quiet! Pure Power 9 700W PSU and it did work. I also tried to plug it into another friend's PC with a be quiet Dark Power Pro 850W PSU and it did work, while another 1080 Ti (from MSI this time) did not work at my end for some reason.
Do you guys think I should change my PSU as it's insufficient for such a build (I know it's not balanced but I can't afford to swap the system completely at once) and I should change it? I was sure that B700 v2 will be enough to power up a 1080 Ti.
I was able to find a thread from a person who has been able to use i7-8700K and 1080 Ti on such PSU and I was able to find builds with B75M-A + i7-3700 + 1080 Ti although idk what PSU they use.
Please let me know your thoughts - what could have gone wrong and what am I missing.
Thanks!
