I7-9700K, MSI Z390-A Pro, ZOTAC RTX 2080 SUPER AMP with 550W PSU

[Valid_Hensel]

Will my Corsair CX550M(550W) work with:

I7 9700K

Noctua NH-D15

ZOTAC GeForce RTX 2080 SUPER AMP

MSI Z390-A Pro

Crucial DDR4 2400MHz 16GB(2x8)

ASUS PCE-N15 N300 Wireless Adapter

Samsung PM961 SSD 256GB M.2 NVMe

Seagate Barracuda 1TB 3,5" HDD

 

Im wondering if the wattage is enough as id like to not have to buy another PSU when i can just use my old one, i think its right on the edge of enough or not. but if it is too much do PSU's have a breaker in them? will they turn of if they're overloaded?:)

No. You will need around 750W

Ok, thanks

It should be barely enough if you drop the GPU power limit to 70% and keep the CPU at stock settings, if not undervolt it.

@Jurrunio It will be unstable and may lead to unexpected crashes

I've done my math, 9700k at stock draws about 150w while 2080 Super Amp's vbios has power limit somewhere between 250w and 280w so 70% will push that back to 200w, giving plenty of room for other stuff and efficiency loss

i will opt for a 750 because i want to overclock the cpu

would the 550 work with my 1070 and the i7 9700k though?

If you want to do that, even a 650W is absolutely plenty. Just get a decent unit, and don't cheap out.

I have an overclocked i7 and titan Xp, it draws 400 watts from the wall, I measured it myself with a watt meter. You will be able to overclock your setup with that 550 watt PSU

It's fine, but if you plan to overclocking with an exact extra-stable-voltage-stability or with the least possible fluctuation, you should go for a PSU twice that capacity. It is not necessary by the way, just as a Sunday afternoon project!

unless you are doing some dry ice overclocking or more exotic. getting something bigger than 550w is unnecessary.

 Exactly!
