[SOLVED] Pci-e 6 pin to 2x 6+2 pci e cable

[viktorhanu]

Hello there guys, recently I've ran in a dilema. I've ordered for my laptop the exp gdc device and a gtx 690, but i didn't wanted to have so much fuss on my desk, so instead of buying a psu, I've bought a dell adapter d220 or something like that. Now my question is, as my gtx 690 requiers 2 x 8 pins to power up, the exp gdc has an 6 pin output female, besides the 8pin input, I've tried to search on ebay,amazon and whatsoever, but the only thing I've found was 6 pin female to 2x6+2 male adaptor. I know some of you might think why don't I just buy a psu, but I'm kinda low on money right now and I cannot afford something good for the moment. If you guys have any recommends? 😀 Appreciate any answer. Thanks

Being low on money is of no concern. It doesn't matter. Save money and buy the correct tool for the job. Otherwise, you're going to be out of a lot more money when something goes wrong with that seriously bad judgement arrangement you want to do.

Things have specific power requirements and capabilities, and are designed to come with specific connectors for a reason, especially when they are specifically excluding something like an 8 pin from it. If a unit doesn't have one, it is BECAUSE it CANNOT support the power requirements that kind of connector must be capable of delivering.

It's a poor idea, and you should abandon it if you value the hardware you DO have. Save, and get the correct hardware that can handle the job safely. Or else being low on money might become a much larger problem.

These kinds of adapters are not safe.

A 6 pin is rated for 75w. Dual 8 pins can deliver 300w.
The 590 will draw a lot more wattage than a single 6 pin can supply, so this can cause a lot of issues.

Okay, I understand, so whats the best way to do it? I've seen many people using a psu to power the things up, will that be okay?

 

[NightHawkRMX]

Yea, a proper psu with dual 8 pin connectors will be the best way.

Any recommendation, like what brands and power should I go for?

According to this the 590 draws somewhere around 425w. You will want a bit of extra wattage and since the pcie slot powered by the dell adapter, I would reccomend a quality 500-550w with dual 8 pin connectors. There is no way any laptop AC adapter can power this GPU, regardless of adapters

Recommendations depend on how much you want to spend.

You should expect to spend over $50 for a good unit.

Those are whole system numbers though. The most that any normal single GPU equipped card can pull, by specification, not counting any "spikes" is 375w. Two 8 pins at 150w each and power to the slot at 75w, maximum, by spec. So even if we say 400w, which is probably unlikely, a very good 450w unit is likely more than enough for that card in that configuration. Consider, unlike if it were being used in a desktop environment, there are no other system demands to be met by the power supply so what the card needs to get fed, is it. 550w would certainly not be overkill though, especially if a more budget type offering is purchased.
