Suitable power supply for 4930k and gtx 760

rthushara · Jul 2, 2014

Hi,
I'm going to build my machine with following components.

i7 4930k processor
Asus p9x79LE motherboard
Asus GTX 760 vga
32GB 1866GHz memory
1 SSD
2TB 7200rpm hard disk
Corsair H90 liquid cpu cooler
Zalman Z11 plus casing

Most of the parts I have already purchased. Please can you help me choosing my Power supply unit. I'm thinking of getting 600W or 650W power supply. I will not overclock my CPU. Will 600W power supply suffiecient for the above spec?

Please advice. Thank you

500w or more will be good.

You want Antec, XFX, Seasonic for quality.

For headroom 650W is good.

XFX Pro 650W: http://pcpartpicker.com/part/xfx-power-supply-p1650snlb9

What is the system being used for ? if it's mostly gaming, you could go with an LGA1150 based i7 processor e.g Intel
Core i7-4770K or i7-4790K , a Z97 motherboard & tone the ram down to 8GB. And then put the savings into a GTX 780 or R9 290.

Either way, looks okay. All the best.

Thanks @Tiny Voices and @Scampi

http://www.extreme.outervision.com/PSUEngine recommends 547W or above for my configuration.
There is a considerable price difference between 600W and 650W power supplies. So I'm thinking which one to buy.
I have already brought CPU and VGA. So no way to change now

That PSU calculator is known to overestimate by ALOT.

500w is plenty for your system. You will barely pull over 350w at load. The gtx760 is very efficient.

A 550w unit is plenty. The XFX550 is a VERY good and cheap PSU.

rthushara :

If you haven't opened them, you could always give them back for a refund.

Personally i'd stick with the 650, the extra headroom will be less of a headache when upgrading the GPU in future. Seeing as your buying one of the best CPU's that will last a good long while, that's what will be upgraded in future no doubt. Plus not pushing the PSU hard will result in it operating quieter.

The XFX is good quality (Seasonic OEM) hence the price premium, if your talking about Corsair CX series, then they aren't as good. It would look odd to see a monster of a processor setup with a value PSU. But it's your decision to make.
