Everything in my PC was working normally until I recently received a GTX 1080 to replace my GTX 1050. I plugged the power cables into the GTX 1080 and powered on the PC. The GPU fans were turned on for the boot and the PC loaded the boot screen. However, after the boot screen the GPU fans powered off, the display was black but there was still a HDMI signal. I repeated this test until I decided to remove the GTX 1080 and just try normal motherboard HDMI display. This also had the same results. I tested the HDMI cable and replugged internal cables. The keyboard and other USB components were also not working when powered.

Here are my PC specs:
- MSI GTX 1080 Armor
- Corsair 600c Case
- Corsair VS450 PSU
- 8GB DDR3 RAM
- 3x 120mm Corsair Case Fans
- Cooler Master 212x CPU Cooler
- LGA 1155 Foxconn Mini-ITX Motherboard
- Intel i5 2400 CPU

Get good quality, not just high quantity.

Corsair TXm, RMx
EVGA G2, G3, G1+
SeaSonic FOCUS, FOCUS Plus, PRIME

550W and up would work just fine with a high quality power supply. 650W is a sweet spot unless 750W or 850W is on sale.

Then there are the mediocre, medium/good quality units.

Corsair CX (2017), CXM, CSM
EVGA B2, B3 (650W)
SeaSonic S12II, M12II 520W or 620W

He did it says Corsair VS450. Not exactly what I would want to use with a GTX 1080, but it should work unless the VS450 has become defective. Even if it did work, I would recommend removing the GTX 1080 as soon as possible and replacing the power supply with something better. Corsair VS is not meant to be used with a gaming system, especially a high-end GPU like a GTX 1080. You are just asking for trouble.

The keyboard and USB components were working before I removed the GTX 1080. There was also no boot screen after I removed the GTX 1080 and put it back in again.

As I said, there are specific models that are good and other models are bad.

Corsair VS is bad. CX (green) are bad.

Most of EVGA's cheap units are not very good and some are bad.

By bad I mean they have been known to fail/go bad and even damage other components in the system.

Most all SeaSonics are good.

Problem solved. After upgrading to a 750w PSU, I found that only one drive, the non windows drive, was being booted. This was because I had not checked the SATA cables, as the cables to my windows drive was not plugged in properly. As a result booting up gave a black screen; not because of the PSU but because of the boot drive config. The PSU upgrade will still help for future upgrades and my PC is running fine now. Thanks for the help anyway.
