Help with choosing PSU

I roughly calculated the power that my rig would use up which is around 806 on 95% load and 856 on full load. Would it be ok if I buy an 860W PSU which can barely withstand the power usage of my rig or is it better to get a PSU with higher wattage for countermeasures? BTW my budget is pretty tight right now.

What's your actual rig? 

Fine you want the PSU tier list? Have the PSU tier list: https://linustechtips.com/main/topic/1116640-psu-tier-list-40-rev-103/

1. What rig on earth draws that much power?

2. Yes 860w would be sufficient as long as its 80+ gold and from a reliable brand. Alot of good psu can operate at full load and give out a consistent ~50 extra watt above their rated limit. Just look at the Cooler Master v700 it can give out a steady 800w at full load

"can deliver almost 850W under load."

80+ rating hasn't got much to do with it... there are some pretty good PSU's out there that aren't certified as they don't automatically switch from 110V to 220V (toggle on back)..

 

But yea, any good PSU should be fine and the 860W (only ones I can think of are the Seasonic built Platinums) are fine..

 

Don't use PSU calculators.. they suck..

I don'T PreSS caPs.. I juST Hit THe keYboARd so HarD iT CriTs :P

 

Quote or @dzzope to get my attention..

Not at all... PCPP just adds up the TDP of components and adds a bit. In reality your system will use leaps and bounds less power than what PCPP will tell you.

My account is almost entirely dormant. Hope you all are having a grand time. Many years of fun were had here.

I use the number PCPP gives me to pick the actual wattage, like if it says 450w (i5 non k and a R9 280)  for a system, I put a 500w PSU in the system just to give it headroom.

In reality a 350W PSU would actually power it but nonetheless....

A 500W PSU of decent quality will work just fine yes.
