To be specific i want to know about the connectors the gpu has 8+6 pin and my psu says it has 2x 6+2 pins..
does that mean that i can power the gpu with 2+6 + 6 pin connectors?
please help.

No way would I run that or any kind of good GPU on that PSU, that's NOT a good quality unit.

Better to get a good quality unit and 650W ideally.

1) Please don't say "low budget" but rather give the actual budget.

2) That 550W unit can run the RTX2070. It's not that bad. It also depends on the CPU etc. In GAMING you'd use maybe 230W or so, so if the CPU + rest of system uses 120W you're still at 350W, and the PEAK Wattage is about 680W though I'd prefer to see no more than 450W for sustained usage.

FAN NOISE is another story but that's a personal thing.

3) New PSU:
If you're going to spend $60 anyway for something half decent, then considering the REST of the money your PC cost then I'd spend a bit more and get something more reliable and quieter. And probably will last longer.

*My top choices are one of these two:

or

You could get less Wattage but the price difference isn't that big, and the fan noise and life of the PSU are affected slightly... anyway, both of these models have excellent fan control (the EVGA G2 model doesn't just so you know. the G3 is above).

Check out the FAN curve for the Seasonic: http://www2.seasonic.com/product/focus-plus-750-gold/

With the Hybrid button unpressed (out) the fan is OFF until 30% load (225W) at which point it kicks in and is very quiet and doesn't even start ramping up until 50% load (375W).

Funny story:
My Corsair PSU was making noises for a while so I thought "will have to buy another PSU eventually so might as well get one now and save myself the hassle as the timing might not be convenient to be without a PC"

So I ordered an EVGA G2 750W unit, plugged it in, and it died a couple hours later.

The point is NOT that the EVGA G2 unit sucks as it's actually well made but that replacing an existing PSU of lower quality with one of higher quality doesn't necessarily work out for you.

Personally I'd buy one of the units I recommended above but I always get a good quality PSU. Maybe that's just because I designed and built some in College that I overthink this because some of the "cheap" PSU's of today are actually still pretty good. It's more RELATIVE than an indication of how they are in general.

(Side note: my fan shuts off at 50% with "ECO MODE" on the EVGA G2. It's noisy without ECO MODE even in light usage. Same as the one that failed quickly so that's a design flaw IMO as a high RPM fan for almost no power is just stupid. Again, they did fix with the G3)
