Question RX 5700XT Led1 and Led2 Not working???

[Bomba__]

So my friend got a RX 5700XT and after he installed and flicked the power supply on he got no led1 or led2 response from the graphics card. He turned on the computer everything boots and it works. After an hour ish he saw that his led1 and led2 started flickering white is this caused by lack of power supply? If so is it a major problem? Since he cant afford a power supply right now since he got a graphics card. Forgot to mention light starts to blink when he plays games.
His specs:
Rx 5700xt Gigabyte Aorus
I3 9100f
H310m m.2 2.0
Silentum pc 450w

You're asked to have have at least 600W of power towards the entire system's disposal.
While TechPowerUp suggest;

AMD Radeon RX 5700 XT Specs

AMD Navi 10, 1905 MHz, 2560 Cores, 160 TMUs, 64 ROPs, 8192 MB GDDR6, 1750 MHz, 256 bit

at least 550W of power...
Your friend's PSU doesn't meet that threshold, and if it's as old as the processor, then you're providing far less power than the GPU needs.

After an hour ish he saw that his led1 and led2 started flickering white is this caused by lack of power supply?
Yes

Is this a major problem? Can he still play games or do stuff on his pc? Beacause he cant afford a psu right now.

How much did he spend on the GPU? ~200USD? More? He can't afford a new PSU but is willing to risk loosing the GPU, noted.

I'd move either to return the GPU or to avoid taxing the GPU or buying a reliably built PSU. Take your pick.

Would undervolting in the amd program help?

Not enough. He needs either to remove the card or upgrade a new power supply unfortunately.
