well ... i use it sometime ... yet i always confirm that the recommended wattage needed is exaggerated ;)

little example with my current main rig setup at 100% load and 8hrs a day setting
Load Wattage:416 W
Recommended UPS rating:800 VA
Recommended PSU Wattage:466 W

(ok ... i have a 750w ... well got a price on that Seasonic so, i kinda did bite the bullet ) but i did ran on a 450w spare psu without any issues

another setup with 2 OC'ed GTX 580 (Matrix Platinum) and a Xeon E3-1275v2 @ 4.0
Load Wattage:766 W
Recommended UPS rating:1400 VA
Recommended PSU Wattage:816 W

(was running easily on a 700w PSU at the time, a InWin Desert Fox gold )


unreliable note really ... exaggerating, most of the time yes ... i think it's rather for keeping"beginner" builder on the safe side (oversafe i should say )

also manufacturer tend to exaggerate power needed too, i.e.: ASUS recommended a 700W for a single 580 Matrix Platinum @ stock , yet i ran 2 of them quite OC'ed on one

Yeah, manufacturers tend to recommend more watts than required too. I think they do this because they know that there are a lot of people running crappy PSUs that can't deliver the wattage they are rated at reliably and they want to avoid unnecessary RMAs on damaged hardware due to that.

those of us with wall meters all know that those PSU estimator websites are steaming piles of fertilizer - they won't risk being sued for saying a low number was safe, so they go really high numbers instead.
It's been said enough times, but yeah its basically to be safe with cheap no-name crappy PSU's.

You can get platinum rated 400W PSU's for example, one of those would blitz the OP's system.

couldn't agree more.

I used to mine coins with 3x 750Tis (FM2+, A4 APU, 4GB DDR3, 1 flash drive, no HDD/ODD) off of a 380W - 6 years old - seasonic PSU, run it for 24x7 for almost 3 months until I add 2 more 750Tis and replace the PSU with a corsair 450W.
