will the new evga 450 b3 be able to run a 980ti

[krispeebacon]

im getting a 980ti from a friend because im giving him an am4 motherboard and 2 gpus that i dont use and was just wondering if this power supply since its new will be fine consindering my ryzen 7 1700 isnt overclocked and i dont plan on overclocking the 980ti

First thing to check is if it has the proper amount of PCIe connectors. so I need to know the exact 980Ti model you plan to buy. Also, please list your full specs.

im not sure what the 980ti is gonna be its more of a surprise model but my specs are

ryzen 7 1700 3ghz
gtx 980ti
evga 450 b3 comes with 2x 8-pin
asrock ab350m pro 4
hyperx savage 120gb ssd
seagate firecuda 1tb

The 980ti tends to be a bit power hungry. My R7 1800X system will draw 450w from the wall under full load with an RX 480.

The 450 B3 is a good PSU but IMO you're pushing it with that. It may work fine, but you may find it crashing, a good chance I think. I would get something 550w or better.

Well the EVGA 450 B3 has two 8-pin PCIe cables. So no GPU with more than that would be allowed. To my knowledge I can't think of any GTX 980Tis that require more than two 8-pin PCIe cables.

Now time to calculate power (for a non-overclocked system). Based on this Tomshardware article on the Ryzen 7 1700, the CPU is 55W when gaming, and when under full stress around 67W. Based on this article here, the reference GTX 980Ti is around 235W when gaming and 255W when under torture. Since the CPU's power is so light, the motherboard should not go over ~15W. Other stuff like fans, hard and solid state drives, and RAM can be assumed a low value of about 15W also.

This means for gaming: 55W + 235W + 15W + 15W = 320W
Under torture: 67W + 255W + 15W + 15W = 352W

These are my own approximations based on my knowledge and data from articles, so even if there is some error here you are well within the tolerable range of the power supply. Assuming the graphics card you buy is not reference but aftermarket, power consumption may also be about 30W higher, bringing gaming consumption to maybe 350W and torture to 382W. Keep in mind that the EVGA 450 B3 has not been reviewed by professionals yet, so its quality and such is largely unknown as of now.

alright thank you very much for youre very detailed thoughts on how i should go about this.

Yes It will be fine with a 70-80 percent load. I have a Simmilar system runing on it now.
