Some help needed

[vnorbi]

Firstly, I'm sorry for misspelled words and grammar mistakes, english is not my native language.

Secondly, I'm not a hardware pro, so sorry if I ask dumb questions.

 

So, today I bought a RX 580 (from here: https://kazycomputers.hu/powercolor-red-dragon-rx580-8gb-gddr5-axrx580-8gbd5-3dhdv2oc-17158?utm_source=arukereso&utm_medium=cpp&utm_campaign=direct_link). After the purchase I realised that I might not have enough power for the GPU to work. Not a long time ago I also realised that my PSU doesn't have any pcie connectors, only two 4-pin molex connectors and two 15-pin sata connectors.

 

Here are my specs:
PSU: Danubius D12-ATX450W 450W
MOBO: ASUS M5-A78L-M LX3
CPU: AMD FX-8300 @3.3Ghz (base clock)
SSD: Samsung QVO 860 1TB
RAM: Samsung DDR3 1 x 4GB
GPU: RX 580 8GB (link above)
Other:
WLAN adapter: TP-Link TL-WN781ND

 

My questions are:
Is the PSU enough for these specs?
- If yes, then is it safe to convert two molex/sata to an 8-pin pcie connector?
- If no, then can you recommend me a cheap, but trustworthy PSU?

The wattage is fine but I'd NOT use that PSU.

A cheap but trustworthy PSU is the Seasonic M12II-620 Evo, it's fully modular, so , you will be able to do some cable management and it only costs 50-60 dollars, it's the best psu at this pricepoint

Yeah, I will replace it soon, but I at the moment I can't

Okay, I'll have a look at it, thanks for the recommendation
