Is 450w Psu enough for a 290x?

dankknightavngr · Jun 26, 2017

I only have a low power G4560 for my cpu, is 450 w enough for 290x?
My Psu is Seasonic G-series 450w 80+Gold... If not I might just go for a slightly slower 970...

No, the 290X was power hungry. Recommended is 600w but a good 550w is probably as low as you can safely go.

Why not a 1060? Better performance and uses less power than both of those.

The 290x is a bit of a power hog. If you can get a 550-600W PSU, that should cover you and have plenty of wiggle room for any other unaccounted for variables.

The GTX 970 is only a tad slower, but does use a little less power as it is a newer and more efficient design. Still though, I would get a little more wattage to cover either card, but it depends on budget and those other variables again.

Your PSU is excellent but the 290x is power hungry. It will be enough if you don't have too many HDDs, fans and other power hungry components. In a review I found with a more demanding CPU, the total system power draw was almost 400w

Running a PSU near max is asking for trouble in my opinion, even on a high quality unit. The 290X can peak around 300w, I personally wouldn't use a 450w.

Ill just get a 970 for less complication

That being said, the 290x is 20$ cheaper Than gtx 970 in my country, I could also sell my current my psu and upgrade it to a 550-650w psu and get the 290x, what you guys think?

Whatever GPU you choose, I think you would still benefit from having a little more power availability. Of course, do what works for your budget, and whatever is easier for you.

That PSU is perfectly capable of running a 290x and that CPU you have.

The Tom's Hardware charts shows the worst 290x pulling 262w on a gaming load, and that's the card alone.

I'm currently mining with a slightly overclocked 290 and the entire system is pulling 265w from the wall.

You may have a version of the 290x that may have a better cooler, and possibly even better build quality. Then there is the silicon lottery. The 290x has a reputation for being a power hog, run hot, and depending on the cooler, it could be a bit noisy.

guys

300 w use gpu http://www.tomshardware.com/reviews/radeon-r9-290x-hawaii-review,3650-29.html
54w cpu tdp https://ark.intel.com/products/97143/Intel-Pentium-Processor-G4560-3M-Cache-3_50-GHz

and another 50w for the rest of the system.

that seasonic is easily capable of powering gpu.
sligghtly slower 970? I would get that 970 any day above the 290x.
