PSU headache

[Space Bumblebee]

Good evening,

After watching your video about fitting the right PSU and how much power your rig will 'actually' draw, I've decided to post my queries on here.

Initially I thought of getting a 650-700 Watt PSU but different people keep recommending different sizes, anything from 500 to 1500 Watts! Which is getting me quite confused. I've calculated that my system might draw between 250-600 watts but this is a rough scramble or information from the manufactures' specs and tests. I've read that PSU's run better and longer at 40-60% load?

My specs:
CPU- i7 4790
GPU- MSI Gaming GTX 970 Twin Frozr
HDD- 2TB Western Digital Black
CPU cooler- Corsair h80i
Mobo- ASUS z97 Pro Gamer
RAM- 16GB (8GB*2) 1.5V yet to order this yet
Will be getting a 120GB SSD or M.2 SSD.
My case, Zalman H1, has five fans in total; four 120mm (one LED) and one 200mm.
Optical drive and an external 1TB hard drive.

I would really appreciate any advice you have for me!!

Thankyou!

You will have enough headroom with a 650W PSU, the smallest I would take personally would be 500W

As said, 500 Watts will do the job. Personally, I'd pick up a 650W unit with a 0RPM fan feature so you'll never really hear it and to have some headroom for upgrades.

Prettymuch this, i have the Corsair HX750i, way overkill for my system but it is a joy to have a silent psu all the time, combined with the 970 fans that stop spinning below 60 degrees, and hello quiet pc!

I'm guessing once you get your hands on to the RMi series will you be able to do a review

Not taking this that far off topic sorry mate.

No problem

Sorry for the delay in reply peeps!
Ah I see, so with a 650W it would be running at 80ish% load if everything was maxed out? Would that reduce the life of the psu?
So perhaps not just 650W, but a 80plus and up version?

Thankyou for all your advice!

Awesome review indeed!!
Is there much difference between this one and say a Corsair RM 650 Fully modular?
I do quite like the look of the Superflower one! What would be your, say, top five 650W PSUs? In general performance, reliability and cost?

Thankyou!
