how many watts is enough?

[syncopied]

i know there are calculators out there, but they vary way too much for me to believe in them. i am building a new system with the following components:

i5-4670k
zotac gtx 660 ti (non amp version)
1 SSD
3 HDD
1 DVDRW
and the rest are standard

i bought one of these Seasonic G series 550W 80+ gold

i know that they say the recommended psu for a gtx 660 ti is 450W, but with that many hard drives and a hungry processor, will it be enough?

3 hard drives is not a lot. An SSD barely even counts, it takes probably 4-5 SSDs to equal a single hard drive. And approximately 20-30 hard drives to equal a high end GPU.

Your processor is not even remotely close to being a power hungry processor.

Your processor tops out at 150 watts in a worse case scenario, overclocked. The 660 will max out around 160 watts, if you're pushing an aggressive overclock on it. The SSD, a measly 2 watts. The hard drives, 5-10 watts each. Everything else (including motherboard, fans, etc), maybe 50 watts. You're looking at ~390 watts with a very aggressive overclock on your CPU and GPU.

thx it always feels better to listen to someone with experience

They have several psu calculators available, such as this one: http://www.thermaltake.outervision.com/

a high quality 550 watt psu is plenty. stock that pc would never pull much more than 300 watts and oced it would never ever pull 400 watts even under full load.

Don't worry, you will be just fine.

You have plenty of power left on the table with that PSU.

Most PSU calculators over compensate the power demands to cover shitty PSUs.
