Small/cool PSU for SFF build

[suicidemonkey]

Hey guys,

I'm doing an SFF build with an Lian-Li TU200 case in the next few weeks. I have all of the hardware except for the power supply. I've been googling for hours trying to find the smallest, coolest running 550-600W PSU that I can, but there's just so many on the market that it's doing my head in.

Can anyone make any recommendations?

For anyone that cares, i'm using an i7 3770, Nvidia 560Ti, 12GB DDR3-1600 RAM, ASUS P8Z77-I DELUXE. It will be a video editing and occasional gaming machine.

Cheers!

Possibly the Silverstone ST50F-P (140 mm) combined with their PP05 set of shorter modular cables?

Thanks for that. Looks to be a bit smaller than most.

I'm wondering if an SFX PSU is an option.. Silverstone have a 450W SFX PSU.. but i'm not sure if that's quite enough for my system..

Seasinic X series 80 plus gold.

The X-series Seasonic are definitely very good, but they're 160 mm long. The lower power S12ii (non-modular) are 140 mm long (like the Silverstone) and the M12ii 520 W and 620 W are 150 mm long. Unless you're using tons of HDD, 450 W should be fine -- you'd just need an adapter plate (which the Silverstone includes).

Thanks for the info.. I'm using 3 HDDs and an SSD.. might give the 450W SFX PSU a go.

To reiterate the above, 450w will be overkill with one lower-power GPU, you'll be fine. HDDs and SSDs don't take up much power.

I plugged your system into this power supply calculator and got 440W required. This is roughly twice the wattage your computer will pull at 85% usage since peak PSU efficiency occurs around 50% of a PSUs maxumum rated wattage. Everything else being equal, choose the PSU with the highest amperage output on the 12V rail.
