GTX580 power

[ikkedee]

GTX580

So I set up my new PC but I can't figure out how to make the GPU work as there aren't enough power connectors.. Any help would be appreciated


Power connectors my PSU has:
24 pin; 4 Pin (12V); 1 x 6 pin PCI-e; 4 x Sata; 3 x 4 pin; 1 x FDD

Power connectors my GPU needs:
8-pin & 6-pin


Would a PCI Express 4 Molex Pin to 6 Pin Power cable adapter be sufficient, e.g. Akasa PCI Express Power Cable Adapter 4 pin to 6 pin

*** No hotlinking, particularly to competitors ***

I got an 8-pin to 2 6-pin adapter with the card by the way.. (which I find very weird)

My PSU is Alpine 750W Silent.

Hello and welcome to the forums

I would remove the link before a mode see's

I would also invest in a decent psu, but in theory it should work.

Edit: £15 PSU

I can't believe you've bought a 350 quid video card and you're expecting to run it on some dog**** 20 quid PSU. Do you want to blow your system up?!?

Hello and welcome to the forums


Are you really going to use a £20 PSU on a very expensive system ? That PSU will blow even before you get to the POST I bet or not even allow the system to POST. If you just purchased that PSU send it back for a refund and get a decent PSU like the Antec, Corsair, XFX PSU's they sell here. A £20 PSU is not going to power a GTX 580 correctly and this is why it has only 1 PCI-E 6pin. Get a PSU that has all the correct connections on it and it is not all about watts with a PSU it is about stable rails and Amps they can provide.

If this is what it looks like you purchased a really terrible PSU there.

The only Item Description I could find was this and it does not state how many rails it has and what their amps are on each rail. This would also make me think stay away when they don't even give you all that information that is important to know.

To be fair, I used a £45 PSU to power my first 580 for months. If it has the watts, and the rail has the amps. It will be fine.

It's all just superstition

Until your PSU blows and takes your nice £400 graphics card with it ^^

Major brand cards don't guarantee your equipment though in the event of failure.

The competitor I bought my generic ownbrand PSU from were so confident in it's stability they guaranteed £1500 worth of hardware hooked up to it in the event of failure.

Corsair and Antec don't do that.

650w should be more than enough for your needs even if you oc the CPU and graphics card but you could go for the 750w versions of the ones I've linked to(bar the lepa g as that comes in 700w and 900w), your motherboard doesn't do sli so you don't need to worry about adding a 2nd 580 in the future.

Thanks! I live in student halls so don't really have to worry about saving power. I think I'll go for the Corsair then, thanks for the advice!

It's about conversion efficiency more than saving power.

If the power supply is 75% efficient, that means that 25% of the input power is being lost in the conversion from AC to DC, and that lost power is mainly converted to heat. A more efficient power supply will not only use less power, but also generate less heat.
