Thinking of getting the Sapphire 5970.

At present I have a Hiper 630 M series PSU with 4x12v rails at 18A on each.

Can this run the 5970, or do I need to 'spalsh the cash'.

Many Thanks

Tom
 
Think you may need a different PSU, you need 650W to run a 5970 and i would always suggest some slight headroom above recommended specs, I have a thermaltake toughpower 750W in my rig.
 
why dont you just buy the card if you are going to anyway, see if it runs on your PSU. If it does great saved money. If it doesnt then buy a new PSU.

easy.

yeah, but if you do that you risk damaging components? better to be safe than sorry with gear that expensive i tell you...
 
In these three reviews full system power consumption at load was between 393 and 529 watts. I don't know where exactly the differences come from, but the 529 watt review was on a system with i7 920 at 3.33ghz, while the other two were i7 965's.

Also antipacker mentioned he ran 4870x2 on your psu with no problems and 4870x2 uses like 80w more power.

So, it should be fine.
 
I have this PSU in one of my i7 systems, and as much as people bash Hiper for being garbage, that PSU of mine has been with me for almost 5 years, and it hasn't failed me yet..

Whether or not it would be good enough for a 5970, I can't say for sure, but going by what Raikiri posted above, it should be more than capable of handling it..
 
A 750-800W would be incredibly close to being able to run a heavily overclocked quad core system with 8gig mem and 2x 5970's, a 600W + psu will have zero trouble with a single 5970.
 
I have nicely overclocked GTX 260s in Sli (675 core, 1200 Mem) with a 4.2GHz i7 that peaks at 520 watts at the wall (the most I have noted with any game) and I think that this PSU should be able to run the 5970 that I expect to get tomorrow ... however, if one stresses both cores to the max AND the CPU (P95??) at the same time then maybe that will stress my PSU a bit too much (625 watt Enermax) so I would recommend to anyone that you cover max CPU plus MAX GPU load to be safe when stress testing (800w should do it :cool:) .. but for me I am gonna try it and see if I can save a few bob using informed decisions because that is how I am - please do as I say and not as I do sort of thing as this is my (informed!) risk to take ...

If I am wrong then watch out for the thread titled 'How I totalled my i7/5970 system' :D

However, having said that, I did literally blow up a 480w crappy cheap 'stop-gap' PSU a few Christmas's ago with a hghly overclocked 6320 + overclocked 8800GTX and worried for near on a week that I had blown something important till I got my new QUALITY psu ! So it can happen!

Bottom line is that if you do not like the 'feeling' that you are chancing it then go for a higher rated or ATI recommended PSU.
