Will my PSU cope with new gfx card?

Skillmister · 13 Dec 2012 at 16:44

As title, will this PSU cope with an i5 3570k, Z77-D3H, 16GB RAM and an upgrade to a 7850 from a 4850?

Thanks

I'd say no.

ATI recommends at least 500W.

According to eXtreme power supply calculator minimum wattage is 321w and recommended is 371w but this is with Cpu and Gpu at stock.
So I would say yes, as the 4850 probably uses more power than the 7850.

I'd say yes. Overclocking may be a little 'ambitious' though.

you'll be pulling around 300W. Your PSU has 30A@12V, so yeah, close but should work. 4850 / 7850 have about the same power draw at stock (100W), overclocking (130W-150W) will add more strain, so do it sparingly.

Cool thanks guys. I'll just take it easy till i get a new PSU some time

Any reviews in this power supply to be found?

The PSU will be fine, I pull 330w max from my system with a GTX 670 and i7 2700k.

I used to run 750w Pc Power & Cooling PSU without issue

This, im amazed by the low power use of modern cpu/gpu's, not that long ago my old i7 920 and sli 470's were pulling 630w in games, (4ghz cpu, 750mhz oc cards). Spec in sig is drawing 330w, with a pretty high oc on the gpu. Im doing my bit to heal the planet.

Very true, my overclocked 920 setup with a 480GTX I managed to get 615w from the mains!

With one card, holy **** mate. Theres me thinking i was bad with two 400 series cards in games. Though, in furmark they pulled 740w. Furmark and prime small fft together, 860w and climbing before i stopped it. Corsair HX850w. I dont do silly things like that anymore.

RJC · 13 Dec 2012 at 23:18

Yep one card, that was Furmark and Prime running together!

Good job you have a decent PSU, 860w and climbing

setter · 13 Dec 2012 at 23:23

Thank god mate, and bought secondhand on MM for the very good price of 90 quid, think ive had it for over 2 years now. It's had an easy period since the 470's are gone. But ill be adding another 670 soon, give the old girl a good kick up the backside again.

Heck, i even bought her some nice fancy blue braided corsair modular cables, shes an old girl who wants to maintain her looks.

Well i've got the card and all is well

No explosions thus far! Can't believe how quiet it is compared to the 4850
