Is A 550W PSU Enough For This Build?

alannm37 · May 28, 2015

Just wanted to know if I'll have enough power to run this 'safely' without any worrying about power consumption. As I've heard AMD cards use a crap tonne more power than Nvidia cards.

Here is the build.

i think if you get it bronze or higher it will be fine. But to be honest I'd go with a 600 watt just to be safe.

It should work ok, but it would be a lot safer to buy a new 600W or 700W PSU for safety. PSU's are not very expensive and all you need is a bronze PSU. AMD recommend about a 600W PSU for the 280x.

It's a Tier 2 Seasonic-made PSU so a very good one. In terms of wattage, I'm running the same processor with an R9 290 (which uses more than the 280X) on a 550W PSU and have never had any issues. Measured at the wall, power draw at gaming was typically around 250-290 W, peaking around 360 W. I think you'll be absolutely fine with that.

Thanks for your replies and suggestions. I 'might' get the 650w just for peace of mind.

As for the suggested "less expensive better parts" build, I don't live in America so if I bought that in Ireland its at least an extra 200/300 euro which I don't have, thanks anyway
