I need to upgrade my PSU. Which one should i choose?

Stijn van Loo · Oct 10, 2014

Hello, I recently upgraded my graphics card from a Asus GTX 650 1GB to a MSI Geforce Twin Frozr GTX 770 2Gb. Now i need a new PSU. How many watt does my new PSU need to have and which one should i choose? Will 650 watt do or do i need at least 750 watt? I want a corsair PSU because all my pc components are from corsair!

Current PC specs:
24inch samsung syncmaster 1920x1080
Inter core i7 3820 @ 3.6GHz (8 CPU's)
16gb RAM
MSI Geforce GTX 770 2GB OC edition.
Windows 7 professional.
Sabertooth x79
Corsair CX500M

Thank you in advance and sorry for my terrible english.

A decent 550W will be from. Get Tier 1 or 2 from this list:

Avoid Corsair CX and CS, there not that great compared to other alternative really. The only good Corsairs' series are AX, HXi, HX, some AXi.
XFX 550W TS or XFX 550W pro will be fine.
650 would be the highest I would choose for a single gpu build.

Suztera :

Thank you for your reply. I was wondering if it is dangerous or risky to game with my current 500 watt PSU. Should i wait until ive installed a better PSU?

You'd need at least 575W with one 6-pin and one 8-pin connectors.

Stijn van Loo :

It is be doable but I don't recommend Corsair CX series to be used due to their internal quality for gaming pcs.

Suztera · Oct 10, 2014

sammy sung :

In theory you need 575W when you are drawing the max TDP from the GTX 770, an overclocked cpu and other parts of the pc. But you most likely never reach 500W. or even 450W. A quality 550W or 650W is enough. 750W is overkill and is aimed more for SLI or people who want their psu's fans to turn off/slow down.

Will a TX650W do?

Suztera · Oct 10, 2014

Stijn van Loo :

Yes, a TX 650W will do.

Only the Corsair AX , AXi , HX , HXi and TX VERSION 2 are good , the rest use poor capacitors.

Link in SR-71's post is the one made by Super Flower. It's worth it.

I would personally get this for your build. EVGA has an ODM of Super Flower, and is based on their LeadEX platform. Super Flower makes amazingly reliable and well performing PSU's. It also is fully modular, with sleeved cables, and comes with a 10 year warrranty. (That is 6 or 7 years longer than a corsair warranty) EDIT: Also, has passive and active cooling.

EVGA Supernova series is also Tier 1 here.

I am very happy with my Supernova G2 850W.

Dark Lord of Tech · Oct 10, 2014

That EVGA isn't a good power supply , you want the B2 , G2 , P2 , T2 series which are made by Super Flower.

Ok thank you for your replys. I will look into it!

Stijn van Loo · Oct 11, 2014

Well guys im from the netherlands and i cant buy those parts in my country

Vic 40 · Oct 11, 2014

What is your budget in euro's?

Stijn van Loo · Oct 11, 2014

Less than 100 euros

Vic 40 · Oct 12, 2014

Wow,hard to react with those huge pics.

A few options,
http://tweakers.net/pricewatch/349127/cooler-master-gm-g650m.html (a cheap and imo good one,i know that others will say no to this one)
http://tweakers.net/pricewatch/360227/seasonic-m12ii-evo-620w.html (the newer model,fully modular) !
http://tweakers.net/pricewatch/349132/cooler-master-v650-semi-modular.html (i like this one) !
http://tweakers.net/pricewatch/348558/corsair-rm650.html
for the ones bitching about this one,it's in the tier 2A from the Psu Tier list from this forum.It should be good.
http://tweakers.net/pricewatch/361903/xfx-xtr-650w.html (a (very) good choice normally and should be according to TechPowerUp) !!
went for 650watts,that cpu can use a lot of power and with overclocking would that even be more.The 550watt versions (not that seasonic=520wat) would probably be good too,but are just a few euro's cheaper.

The ones with four or five starts are normally good shops,look at least above three stars to be sure I mainly use Afuture by now,but Azerty also has a good rep,4launch should be good too and is also under budget,not taking into account the postal costs.With Afuture are there no postal costs right now! This means that the corsair would be under that budget you gave.
Still,with that seasonic (or the cooler master gm) would you save quite a lot of money,enough for a nice cooler on that cpu if you don't already have that.
Well there's something to be said for each of those,read some reviews about them and make up your mind.

Thank you! but is 750 watt not a bit to much?

Vic 40 · Oct 12, 2014

Stijn van Loo :

For sli would it be good,but for one card a bit much,even 650watt is already much,550watt should already be fine.But like i said are the 650watt units just a few euro's more expensive and like the moderator says,it doesn't hurt.
Which one you choose is up to you,but with that seasonic 620watt would you make a good choice for a good price.

maxtex · Oct 12, 2014

If you want corsair just get a RM, no need to think about it more. A 550 will be enough, a 650 is fine too.

Stijn van Loo · Oct 12, 2014

Okay everything is clear now ! I want to thank everybody for their help !

I need to upgrade my PSU. Which one should i choose?
