The PSU isn't that great looking at https://images-na.ssl-images-amazon.com/images/I/71mpPO77ZSL._SL1000_.jpg
No, I can't tell you it's that but it's a problem with it's rather low +12V Ampere rating.
Then you find some motherboards don't like new GPUs. The motherboard maker has to be asked about that.
Hi,
I need help with "Gigabyte GeForce GTX 1050 Ti" graphics card. I plugged in monitor by HDMI to the graphics card port and I get no display on the monitor, even BIOS doesn't show. Earlier was connected "NVIDIA GeForce GT 440" graphics card which works fine.
In "Gigabyte GeForce GTX 1050 Ti" there is 6-pin power socket slot, but on my PSU there is no such cable, so I connect GPU with dual molex to 6-pin cable. BIOS is upgraded to newest version.
Computer specs:
CPU Type: QuadCore Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz
Motherboard Name: ASRock H61M-VS
System Memory: 16342 MB (DDR3-1600 DDR3 SDRAM)
BIOS Type: AMI (09/10/2012), Supported Standards-DMI, ACPI, UEFI
DMI BIOS Version: P2.70
Monitor: Samsung SyncMaster T24A350
PSU: Linkworld PSU LPK12-25E 420W ATX
Thanks,
Pavel
