Can my PSU handle 2 5870's?

!TIMMY! · 18 Jul 2010 at 10:49

I have an Enermax Modu82+ 625w PSU and I want to get either crossfire 5850's or 5870's. The 5850's use less power than my current 2 oced 4870 1gb's so I think they will be fine even when oced. But I don't know if it will be able to handle 2 5870's oced.

In my PC (as well as my sig) is 3 150gb raptors, 2 Samsung F3's, water cooling, 8 fans and 2 DVD drives.

I don't want to have to buy a new PSU just to run the 5870's over the 5850's, any advice would be great.

What wattage is your PSU?

I use crossfire 5850 & i7 @ 4ghz, my system pulls 430w from the mains at full load.

Lol I forgot the most important bit, it's 625w.

Yes it can quite easily. You'd only be using about 400-500w full load.

Should be fine, you will need to check your connections as I think the 5870 comes with 1 x 6 pin & 1 x 8 pin connectors.

!TIMMY! · 18 Jul 2010 at 14:49

That's a good point as I have 4 6 pin connectors. Do the reference 5870's have 2 x 6 pin or do all 5870's need a 6 and a 8 pin?

625 is more than enough for what you need, i dont know about the connectors though....adapters are a dime a dozen on the bay anyway

!TIMMY! · 18 Jul 2010 at 16:16

Cheers for the replies, I think ill try and get a 5870 now and another at a later date, just need to gauge how far the price is going to drop. Don't want to buy it now and see it drop £20 the following week.

I've tried running a GPU using a 6-8 pin adaptor and it wasn't particularly successful, I'd suggest looking at a new PSU if you can afford it especially if you're thinking about CFing in the future.

My reference XFX 5870 uses 2 x 6pin connections.

Nerusy · 18 Jul 2010 at 18:26

only new asus 5870 needs 1x6 1x8 pin as far as I know, normal reference or asus or xfx needs 2x6 pin but check in the description box just in case before buying obviously.

my reference asus 5870 uses 2 x 6pin connections.

_lecro_ · 18 Jul 2010 at 18:35

Yep 2x6 pins on my Asus

!TIMMY! · 18 Jul 2010 at 19:23

quality, thanks for the replies, ill try and get hold of a Asus reference cooler one.

Mr Krugga · 18 Jul 2010 at 20:18

You should be just fine, I bought mine with Crossfire 5850s in mind
