Required PSU Wattage for R9 290

[don_svetlio]

Cause fk TT. Based on my experience with pc building I'd always get a nice corsair

Or you got unlucky if you had a 600w psu

Corsair RMi, HX, HXi, AX, AXi are good - cause they're essentially SeaSonic PSUs. RM are decent but overpriced for what they are and CX are a total flop. CWT also make TT so their track record is mediocre.

HOLY NECRO

One guy I know have a 500W but I think a 650W is lowest I would dare to go... (750W if you use a FX-9590)

In my eyes if your CPU draws more power at stock speeds then your GPU then there's a big imbalance if you run a fx 9590 you'd probably want to get 850w and a custom loop to cool that hot mess

Funny enough my brother has been using a cx650 for about 2 years just fine, though I got him that as an overkill PSU for an MSI 7770 and fx 4100 because less load = less likely to melt . Now he runs the same but with a gtx 960. So far so good [emoji14]

And as for my tx750m, I assume that's a discontinued line but hell, its still doing a great job with oc i7, gtx 970, 3hdds, 2 ssds [emoji14]

So, I decided. I'm buying an R9 290 Tri-x from Sapphire.

But, I'm worried my Corsair 600W 80+ is not going to be enough...

 

I have 1 HDD, 1 DVD/RW ROM, Core i5 3330 , 2 DDR3 RAM sticks and 4 fans.

 

So, I checked how much power my rig will need with Cooler Master's PSU Calculator and MSI's PSU Calculator.

 

CoolerMater's PSU Calculator: 463W

MSI's PSU Calcuator: 357W

 

WTF?  That's a 100W difference.

I know this is just an esimate but still!

 

I also checked on Sapphire's website. According to them, I need a 750W PSU!!!

Let's assume this "750W PSU" is only 80+ certified. 80% * 750W = 600W

 

Every comment is appriciated, but I'd like to get an oppinion from someone who know's what he's talking about.

Can my PSU power my rig? Even when I'm running both CPU and GPU at full load? Will it be stable?

I don't to destroy my PC.

well if your psu is 80+ you only need 500w to be safe in a normal system. if you wanna oc 600w would be better

Try a 1st gen i7 extreme edition OC and tell me what happens

You think 9590 is hungry? You gotta try those things.

Haha yeah that's comparing 65nm to 22 i think? Quite a few years between them. The 9*** amd CPUs are fairly recent. Rubbish but recent.

Hah - I just watned to remind ya of those

Intel were the same once - back then Phenom II X6 1100T was a better deal than the original i7s

Yeah but AMD says 750W as "minimum" so I would say a Intel CPU is safe on 650W and probably also 550W!
