Question about 6 pin power connectors

[Big Cool]

Hello everyone

Just today I got my new XFX 7870 as an upgrade for my rather low end 5670. The issue I'm having is that I need two 6 pin power connectors for my new card but I don't have them as my 5670 didn't even need to be connected to the PSU.

This is kinda embarrassing but I'm trying to buy some online but for the life of me I can't find any. I'm not the most computer literate person around so maybe I'm being dopey but I can't find it. I'd really appreciate it if someone could give me some links from either Amazon UK or ScanUK. This is the card:

Thank you if anyone can help me :D

You should really post the make and model of the power supply. If it doesn't have at least one 6-pin PCI-E connector, that is a bad sign that your power supply may not be able to support the wattage of that new card.

[Big Cool]

Ah yes.

My PSU is not the best I'm afraid but I already confirmed the card can run on it with a friend of mine who works in IT. It's a 550W CoolerMaster.

It did come with a power connector but I never had any need for it and quite clumsily lost it when I was moving overseas.

what power supply do you have?
brand/model

Commence the mockery, I know I didn't make the best choice with this.

I'm 99% certain it should work as I did do research on this beforehand. The issue is no power connectors and where can I purchase them.

its kinda weak and inefficient, but should work

get a better power supply when you can

The power supply you linked does have a pair of 6 pin connectors, they'll have another 2 pins clippd to one side of the plug so will look like 8 instead, if that is the model you have they'll be there. it's non modular so it's not like they could have fallen off.

There's a link to a 4pin Molex x2 > 6pin PCIe power connection by the way, scanUK does have them. You'd need two of those though to power the card, if it needs 2x 6pin connections. I'd bet the plugs are there anyways, bought myself a thermaltake PSU last month, had a 4+4 power connection for the CPU on it, that looked like 8 rather than what it was.

Thank you very much man! So these will work right, just to double check?

Big thanks to everyone's posts/help. A new PSU is for sure a priority of mine but spending £210 on a new GPU+RAM has drained my budget a bit. In a month or so I shall upgrade.

[H3X]

Provided you have the molex plugs to spare they should work fine, though as I said before, I'd have thought the connectors are on the PSU anyway if it is that model coolermaster you're using.

When you do look to upgrade your PSU, the Corsair that _I_ linked is a good model for the price, you'd be looking at doubling that for anything with better efficiency and a 80+ gold rating, for example. if you have the budget for it though, they can be worth the price, if you use the machine a lot.

Here's a good gold rated PSU, for a pretty respectable price, though there's a 650w model for about £12 more, might be a better bet if you go for one of these kinda things:

What I use, and would definitely recommend if you can afford one:
http://www.scan.co.uk/products/650w-thermaltake-tgp-650-modular-93-eff-80-plus-gold-sli-crossfire-eps-12v-quiet-fan-atx-psu

that thing will run pretty much anything, but it costs quite a bit i will admit. Oh, and yes, these are simi modular, keeps cable clutter down a bit. if you search scan for non modular PSUs you might get a bit cheaper than these, but likely not much. you get what you pay for more often than not when it comes to PSUs though.

If you use one of these, make sure you connect them to two unused connectors (that have nothing else plugged into them). The whole reason you need two of these is to prevent the wires from burning up due to having too much power traveling through them. If you connect this adapter to the same cable as your existing six pin plug, it could cause a fire.

[Legendary old man]

He does not need the adapters. That PSU has them already. They are not plugged into anything so he just needs to find them.

That PSU is just 16 amps on each rail. Next time get a single rail PSU or a very large duel rail.

[Big Cool]

Wait I'm confused now.

All I want to do is connect my GPU to my PSU. The issue is I do not have any 6 pin connectors.

Will the molex to 6 pin power cables work?

Sorry for my lack of knowledge.

[[☥] - CJ -]

Yes the Molex to 6pin PCI-E will work, though most people dont recommend using them.

Try to have each Molex on a seperate one on the PSU, try not to use the same one. If you dont have many Molex's on the PSU then u may not have any choice but to double up.

[Big Cool]

Okay then

It'd be nice if the 6 pin cables were just sold seperately
