[SOLVED] Will my PSU be able to power this GPU - Gigabyte Radeon Rx 5700 Xt Gaming OC 8G ?

Hello people of TH!

Straight to the point. My PSU is this https://www.coolermaster.com/catalog/legacy-products/power/b500-ver2/

1. Will it be able to power(and connect to) this GPU which im planing to buy ? I saw that i have 2 x PCI-e 6+2pins connectors but i will post a picture of them here Pic1 and Pic2
2. However my motherboard is Gigabyte p55-US3L ver 2.0
3. Will it be a problem that the GPU is PCIE 4 and my motherboard is PCIE2? I know that if it is a PCIE4 GPU working on a PCIE3 motherboard it wont be a problem but i am worrying about this.

4. Please dont question my decision to buy this graphics card..... I had a Gigabyte Nvidia Geforce gt630 2gb ddr3 by now. My configuration is old, I know... ! But i`m planing to build a new PC in the upcomming 2020 or end of 2020. I am planing to try to play CS GO at first and if it is possible to play Battlefield 1 i am planing to play that too. If it is possible without risking my new gpu or destroying my build. Is it likely that i ruin my 2010 build ?

My PC configuration:
Motherboard: P55-us3l
HDD 7200rpm Seagate
4gb Kingston RAM DDR3
CPU: i3 530 dual core 2.9ghz

Recommended minimum power supply is 600W for the 5700XT so I wouldn't do it. It may power on but once you put a heavy load on the system the PS will probably hit its limit and could damage your system.

Besides the power supply, theoretically, the card should work fine but there may be a compatibility issue with your motherboard BIOS supporting such a new card.

If it works at all, you would be completely CPU limited in this set up - the 5700XT would run very slow due to the rest of your system.

All in all, this is not a good idea. I know you are trying to maximize your buying power - which is smart, but you risk damaging components with that PS and may have issues with such a new card working on that old motherboard.

And it's not even just the wattage, it's the quality as well and this ancient PSU is quite low quality. It was probably fine when talking a GT 630, but this is essentially a 450W PSU of ancient design and I would never even consider pairing it with a power-hungry GPU. This was a low-end group-regulated platform a decade ago and while suitable for an office PC or a very light gaming rig (like your old one), I would strongly recommend not using it in this use case.

Thank you for the reply ! Much appreciated ! So should i buy the graphics card anyways because i am getting it for a lot less on black friday here in Bulgaria and go to a PC service or something just to test the GPU if it is working properly ? Like a bench test i mean. Would they do that ? Just to make sure the component is working properly for the future build.
