PSU and GPU compatibility?

Adster3000 · 18 Jul 2010 at 18:07

Hi,

Can an OCZ StealthXStream 500W PSU power an XFX Radeon HD 5850 1024MB GPU sufficiently?

Thanks.

What's the rest of the machine?

ASRock M3A770DE AMD770 motherboard,
AMD Athlon II X3 Tri Core 440 3.00GHz CPU
And Corsair XMS3 4GB (2x2GB) DDR3 RAM.
Along with a 300GB HDD and DVD drive.

it will be fine.

Should be fine

Thanks, though I'm a bit worried about the amperage.. I've been told to be careful, which I'm trying to be.

Any other feedback? I need to be absolutely sure that it'll be fine, the £500 it'll cost me is a lot of money to me, so apologies.. ><

Should do the job but you sure you won't want to crossfire later on? in which case its not enough watts?

Also PSU is really the most important part of your computer, it is PC's heart that pumps energy through it so never ever cheap out on a PSU, better to spend a little more and get the very best you can.

It will power your pc with over 200w to spare. The rig in my siggy only pulls 274w at the wall fully loaded.

I agree, though I will not be Crossfiring in the future, I just need something that will make do now, if I upgrade parts in the future, I'll definitely upgrade the PSU.

The reason why I don't want to upgrade is I've literally hit the limit of my budget (6p off..) and am trying to get this ordered either today or tomorrow.

It's not necessary that I have it ordered by then, I'm just fairly looking forward to having these components to build.

I run a i7 @ 4ghz with 2 5850 in crossfire and this pulls 430w at full load.

Adster3000 · 18 Jul 2010 at 18:59

I understand the wattage is sufficient, it's just the amperage I'm worried about.

But if you guys are sure..

I have one more question, does the heatsinc that comes with that processor (it's retail) have the thermal paste pre-applied? I've looked at similar AMD CPU unboxings on Youtube, such as the Phenom IIs and they are.

Wow. I'm running a single 4890 and use just a little less when furmark and primed up. Didn't know the 4890s were that bad for the national grid.

RJC · 18 Jul 2010 at 19:07

I used to have the 4870x2 which pulled a lot more!

Adster3000 · 18 Jul 2010 at 19:28

Anyone have any input in regards to amps then?

And my heatsinc question,

Thanks.

Adster3000 · 18 Jul 2010 at 20:17

All right.. I hope, will order the components either tonight or tomorrow.

Wish me luck.

RJC · 18 Jul 2010 at 20:27

You be fine

But I would have one of these on standby
