buying power supply/psu suggestions??

[L0stChild]

currently have a bottom tier psu,
Corsair CX 600
no problems with it so far but i think its time to swap it out as im starting to invest in my rig. last thing i want is to have the heart of the rig die and take everything else with it.

im most likely buying from http://www.ncix.com
the cooler master psu calculator shows 530w and 550w for my future added upgrades and recommends a 650w psu which seems to be the typical.
**question though: is it better off to get a psu under/over/exact wattage ratings to match the rigs needs?

most psu would be an upgrade for me but i just want to grab the best deal (full modular, +warranty)


so far im lookin at:

A G2 or P2 from EVGA are fantastic choices , rest on the list not so good.

Summary

In what comes as no surprise to me after all this time of looking at EVGA's units, the P2 650 watt model is one fantastic performer. It has some of the lowest ripple I've ever seen, it's as stable as I've ever seen, and it runs so cool it hardly ever needs to turn the fan on. Now, if you'll excuse me, there's a computer right over here with EVGA's name on it.

The Good:

amazing ripple suppression
fantastic voltage stability
fully modular
exceptional low load efficiency
ran fanless most of the time

The Bad:

zippo

The Mediocre:

why does a 650W unit need two CPU connectors?

PSU Tier list
http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

GOOD PSU EVGA is a B2, G2, P2, GS, PS, or T2. Avoid the EVGA B1 and G1 series

thanks for the replies.
thinking of the 650 p2..

i probably shouldnt have put the cs650m on the list.. it is a old psu. that being said my shittier psu seems to be working with my new skylake..

hey mr stealthbird u violated my post, that link doesnt work lol
but yeah i could actually make it down to the store now. but will just let it sit for a night
price is reasonable considering it is $190 regular price.. knockin off instant $50 and another mailin $10

650 P2 is amazing that was the review from johnnyguru.

ill do a bit more research and price matching.
but my question is still unanswered
**question though: is it better off to get a psu under/over/exact wattage ratings to match the rigs needs?

if the psu is converting and has the potential to put out lets say 150watts more than what ur total consumption is.. whats happens?

Unless I'm misunderstanding the question, a PSU's maximum wattage isn't what it's drawing at all times. Your PSU is never putting out 150W more than your computer's consumption. Like when you adjust your water faucet for water flow, the PSU is only giving out as much power as the PC asks for.

 

[L0stChild]

oh ok so there arent any cons for getting a more powerful psu?
does it just regulate what it takes from the outlet depending on what the computer needs?
just curious if its drawing more electricity and if that amount is significant in the long run

 

[RARRAF]

yes you ansewered your own question really I have a 650watt but it will only draw what it needs I very much dought that I draw more than 500 at max but the quality of the PSU matters a lot you spend a lot of money on PC parts and belive it or not the PSU is important

well yeah i can sorta figure things out logically but id rather have a definitive answer

and to cap it off.. i put the order in for the EVGA SUPERNOVA 650 P2 80 PLUS PLATINUM CERTIFIED 650W FULLY MODULAR POWER SUPPLY 10YR WARRANTY
came out to $156CAD -$10 after MIR
most likely will keep this psu for as long as i need.

thanks for all the comments was easier for me to decide with the info and suggestions.
i gave DSzymborski post as best solution b/c it helped me with my what and why.

Excellent PSU. It ought to last you a long time. The PSU is the heart of the PC and you'll feel a lot better over the years knowing you made the investment.
