I currently have enough to get a RTX 2070 and a cable to convert 6-pin to 8-pin but I'm wondering if my power supply will be enough to run the card it has 2x 6-pins.

I'm currently running a GTX 1060 3GB + Intel core i7-7700 the exact computer is a IBuypower BB930.

After some research I found that this is the power supply for the PC:

I can get the graphics card + converter cable shipped to me over night but I won't be able to afford a new PSU for 2 weeks so will my current one work for now as long as I'm not doing any overclocking?

For more information:
The GPU I'm looking at is:

The cable to convert is:

if it's a decent 500W power supply I would say no issue. but this one is a very low end psu.

my suggestion is not worth the risk.

2070 draws a lot of power from your psu. your psu has two 12V rails of 18A each (and assume if this is true), I don't think a single rail could hold a 2070 at full load, depending on how the cables are wired, if you can get both 12V rail on the 2070, then I guess in theory it's possible. however, with $500 at stake, I think it's best to avoid running 2070 off this psu.

What is the cheapest PSU that would run good with this card on newegg?
 
Good job on researching the psu.
That psu is a cheap unit that does not deliver advertised power on 12v where your card and the processor needs it.

I would not take a chance.
The problem is not that the psu will not deliver adequate power, but if it should fail under load, it may damage anything it is connected to.

I think EVGA may well ship an 8 pin adapter cable with the gpu.

Do not go cheap on a replacement psu.
Seasonic is always a safe bet. 550w is about right.
The older S12 units are ok and cheap.

But, I would hold out for a Seasonic focus gold in 550/650w size.
A good psu will last a long time and allow a future strong graphics card upgrade.

Here is a 550w unit with 10 years warranty:

650W is something I would suggest, it leaves some room for future upgrade as well.

60 with 15 MIR

Well I don't think I will be doing any future upgrading with this PC because it's limited to 1 SLI card slot and it already has a pretty good CPU so if I ever do upgrade in the future I will be saving up for a new pc. I was looking at this PSU because it said the preferred requirements are 550W Gold Certified so let me know if this one will work fine?

The one you linked me is Bronze but 650W would that work cause it said required 550W Gold Certified.

Okay well my question then is would a 650W Bronze Certified PSU work because the requirements said 550W Gold Certified?

gold and bronze makes little difference in terms of power requirement, both rate can supply 550w without issue, gold rated psu has higher efficiency and made with higher quality parts or more efficient design.

looking at the review for the rosewill psu, it seems to have very inconsistent quality. I would suggest away from rosewill. Both corsair unit has 80% (4star/5star reviews off newegg). you could also go with a Seasonic unit as they are a tier 1 psu manufacturer.

Okay my final question is with these power supplies does the cords come with them like the 6+2 pin cord for the gpu?
