Is my psu good enough?

Vichy97 · Jul 22, 2014

My build is:

Motherboard: z77x ud3h
Psu: Corsair builder 650w bronze+
Cpu: i5-3570k
gpu: radeon r9 270x

It runs fine right now but i was thinking of upgrading with another r9 270x with crossfire and adding 4 more case fans and a new cpu cooler so i can OC and a new ssd. Will my power supply be good enough to handle this or will i need to upgrade?

Yes it's more than enough power for your specs.

If you want to add another card you will need 700-750w.

Vichy97 · Jul 22, 2014

I know it is enough now becuase i have had this build for almost a year, but do you mean i need to upgrade my psu to crossfire? also does OC affect it?

Dark Lord of Tech · Jul 22, 2014

Yes you should , it's not enough power and it's a poor quality supply.

iceclock · Jul 22, 2014

yes that will be more than enought sir.

and will support crossfired 270xs

Vichy97 · Jul 22, 2014

well.... who should i believe? what will happen if i try to run it and its not enough?

Well, looks like we have two xperts saying differents things about the same topic :??:

.
Try to use this calculator and check the recommended power output for a crossfire and OC build so you have an idea of what you already have or are going to get.

id say its not enough. sure, it may be able to power 270x's in crossfire, but itd be running near full load. its already a bad quality unit, so running it at full load for any amount of time can damage the psu and your other components. id reccomend atleast a 750W, (850W for future upgrades) solid quality unit from seasonic, xfx, corsair, or antec. use this list to help you choose. you'll want a psu in the 1st and 2nd tiers.

either way i will have to replace my psu so do you think it would be ok to continue using the psu i have now then upgrade in the future when it dies?

jshoop · Jul 22, 2014

the risk of doing that is when your psu dies, it can take your other components with it. it can fry both your 270x's, your motherboard, anything. id say its too big of a risk. i suggest getting a better psu now and waiting on the crossfire

Vichy97 · Jul 22, 2014

hmmm according to newegg wattage calculater i need a 1536 watt....

pit_1209 · Jul 22, 2014

Vichy97 :

You clearly did something wrong there...

Vichy97 · Jul 22, 2014

haha no i double checked everything i think their calculator is messed up. Since i dont want to pay 90$ for a new psu and mine is fairly new and in good condition, is there anywhere i can sell or trade in my old psu?

jshoop · Jul 22, 2014

i tried it and the newegg calculator is bugged out for some reason with that configuration. try a different calculator

jshoop · Jul 22, 2014

Vichy97 :

you can try craigslist, the deals section here at toms, ebay, etc.

Vichy97 · Jul 22, 2014

Vichy97 · Jul 22, 2014

im not really sure if you would know but how much do you think i could sell a used 650w for? most of the used 750w are going for around 100$ which seems like a lot to me

Vichy97 · Jul 22, 2014

thank you again for all your help!

Vichy97 · Jul 22, 2014

oh and one more question what is the difference between 80 PLUS gold and bronze?

iceclock · Jul 22, 2014

only power efficiency

jshoop · Jul 22, 2014

for your psu its not gonna fetch $100. how much did you get it for? id try to sell it for half that. $30 or $40

Dark Lord of Tech · Jul 22, 2014

A good 700 - 750 watt is more than enough.

iceclock · Jul 22, 2014

what sr-71 said

Vichy97 · Jul 22, 2014

ya thats what i think i will get. the coorsair builder 750w bronze+ is only 60$ on newegg with a rebate! such a good deal

Is my psu good enough?
