PSU connectors for GPU

[Ilija Radojkovic]

I've just bought new gtx1060 strix, but I don't know how to connect power cable to it, since it has 8pin which my PSU doesn't have. I've got one 500w PSU, it's not really good, but i thought i could use it for a month before i buy a good one. This PSU has 4pin CPU, 24pin mobo, 4 sata and 2molex connectors, but one of those molex got 2 of its cables puled out then isolated. What power adapter should i buy? I've never built PC, especially not brand new expensive one.

In general if your PSU don't have the right connector then it's not good enough to use.

Hello Ilija Radojkovic

can you list the CPU, Motherboard, Video Card, and Memory Make and Model Please, it will help to identify what you need as power supply.
also this is a custom built computer or a commercial built computer case ? what brand would that be if it is ?

 

[Ilija Radojkovic]

It's a custom build.
H110M PRO-D MSI Mobo
Intel i5-6500
8GB DDR4 RAM
GTX 1060 ASUS Strix OC

I was searching online and people say that 500w will be more than enough even tho it probably has lower wattage because it's not new and high-quality one.

sorry forgot to ask what make model 500w power supply you got

L&C LC-8500BTX

Don't use that PSU. Its highly likely that a PSU that doesn't a 6+2 pin connector is absolute garbage. These low quality units never meet their rated wattage, plenty of reviews showing such low end PSU's failing with as little as 50% of their rated wattage. The risk is if it fails it can damage other components in your PC including the GPU. Get yourself a decent quality PSU with the correct connectors.

Not perfect but useful

You can get an adaptor from Molex to Video card connector yes they cost about 4-7 $ and you could limp on with it.. but I would seriously consider that if the power supply isn't good enough to handle it, it could cause other issues electrically to the motherboard, cpu and video card.. I think getting a better power supply should be one of your priorities.

from your hardware peeks at 250w with the new video card I woud look at 450w from EVGA or Seasonic.

Those brands are way overpriced here because they are rare on our market, what about Corsair CX430W or CX500W?
Both are 80plus certified.

Those are from the old CX range. The 430w is slightly better quality but both are poor. However Corsair refreshed the range with the new grey labelled versions, the CX450M or CX550M are much better http://www.corsair.com/en-gb/cx-series-cx450m-450-watt-80-plus-bronze-certified-modular-atx-psu-uk

Don't get a CX with a green label

I'm on tight budget right now, I thought i could use my PSU until next month so I could save up for high-quality PSU, looks like i was wrong...
I guess my parts will sit in boxes and wait for PSU, it's painful 😀

I would NOT attempt to use an adapter to power the card for a month like you suggested earlier. Your current PSU is garbage. Don't force garbage to power more than it should. Ever. Hold onto your card until you can get a real PSU. My first 500W PSU had 34A on the 12V rails (408W) and two 6pin PCIe plugs. This was a LONG time ago before 8pin plugs came out. That you have a 500W PSU with no PCIe plugs tells me it's a very low end unit that wasn't designed to power modern video cards.

I wouldn't get that 430W Corsair, though the 500 might not be bad. Keep it cool and it should do ok.
