ati 5970 Coolermaster 700W enough ?

[dan7777]

Hi, Folks ive just ordered a 5970 and am wondering if my Coolermaster 700W PSU is enough ? cheers

[dan7777]

anyone ???

[Dezmen]

Yes but i suggest upgrade to 850 or 1000

[Helloworld_98]

well nvidia recommends a 600w for the GTX 480, and the 480 uses more power than the 5970 so yeah.

[dan7777]

so i should be ok then with this ?

[trn]

I don't think so. Off the top of my head I think the max the 5970 draws is 588W and an i7 @ 4.2GHz draws 200W+ at peak plus other devices. Roughly looking at just those numbers I'd want a 1000W PSU. People here do run 5970's and overclock on 850W PSU's but if your upgrading its nice to have a little overhead.

*EDIT: i'm pretty sure i'm misquoting the 5970 Power usage here; I think its 288W.

[dan7777]

whats the worst that can happen if its not enough? so what you reccomend ?

[trn]

Nothing harmful should happen so you can always give it a try and see if it works and if it does don't upgrade. When I first bought my 5870 I tried it in my OC'd q6600 and the 650W PSU didn't have enough power to run both so the system just didn't boot. Went out that day and bought a Corsair 1000W PSU. Only bad thing that happened was I got ripped off by paying local retailer pricing + tax vs online shopping for a PSU.

However, if the setup does work but hardly then you could run into future PSU problems, 2 things could happen. 1, The PSU fails after some time from the added stress and burns out. 2, PSU capabilities fade over time as the caps are used so while it might be fine now, maybe in 6 months your system starts to shutdown when gaming etc.

Judging from your tone; give the system a try first. You won't hurt your new 5970, keep in mind that you may have some PSU issues in the future so if it starts acting up you already have a clue why.

ok mate thanks for advice think i might get a corsair 850W

You could try an online PSU calculator first also http://www.thermaltake.outervision.com/Power. Don't take my word for it before you spend your money I plugged in a system similar to yours and it says ~500W - 520W; so i'm sure I was way off when quoting the 5970 power usage. I can't seem to easily find the max power usage of the 5970 easily so i'm just going from memory (already wrong once) I think the 5970 uses 288W at max (fits in under the max 300W PCI-E spec?)

Maybe someone else could chime in with the right 5970 power usage numbers (and correct me.)

i just did a caculation and came up with 650W used so it seems i should be ok ?

[roki977]

More than enought. I ran 5870 in cf on tx650 without any problems even 3x5850 on same tx650 with overclocked i7 950 for 3d06 high score

I'd personally like a little bit more headroom, is running at 90% load good?

the 5970 is right at 200-220W but im sure that it will be oced so i would expect around 300W

anyways u have more than enough with that 700W CM but the CM psus are not the most reliable or stable (for under 850-1kw i forgot were the cut off was)

get it tues-weds so i will run it at stock speeds till i get corsair 850W or 1000W which one would be better ? cheers all for help.

the psu humping @ 50% max under full load is a good safe setup for extended play duration use

so what would i be safe with 700W psu around 90% load or get a Corsair 850?

Get the 1000W and then you'll "know" and also sleep better!

[wez]

Get the 1000W and then you'll "know" and also sleep better!

Indeed, you'll sleep better and have less noise and heat. Win-win

ordered the CORSAIR 1000W

well i'm running the rig in my sig on a corsair 650w... the psu wasn't the problem unless it's a ty cheap one

[Glow9]

seems like all the progess we're making in lower voltages isn't really true we keep needing bigger psu's

[Smoking]

Moddified Fortron 700W did't make any faces when 975@5000mhz and 5970@1000Mhz....
I think 24/7 700W PSU is good enough.
