Help me with my power supply

tom_taylor97 · Apr 10, 2013

I am building my first computer and unsure of what power supply to buy. I need a fully modular power supply because it is going to be in a bitfenix prodigy case. Will the XFX 850W Pro Black Edition Fully Modular power supply be ok or will it be too much or too big?
The other parts i am going to use are:
Intel Core i7 3770k (Overclocked to 4.6GHz)
Corsair H100i Hydro CPU Cooler
ASRock Fatal1ty Z77 Professional Micro ATX Motherboard
Corsair Vengeance Low Profile 8GB DDR3 Memory
OCZ Agility 3 240GB Solid State Drive
Seagate Momentus XT Hybrid Sata 3 750GB Hard Drive
Gigabyte GeForce GTX 670 OC 4GB Graphics Card

Any help on the power supply would be greatly appreciated.

850W is overkill for that system. If it was the only PSU that would fit it would be okay, but you should be able to find something lower-wattage and cheaper.

A Seasonic M12II 620W would be plenty.

As for the rest of the system, you might consider a 250GB Samsung 840 instead of the OCZ Agility 3. And with a large SSD, a hybrid HDD seems a bit superfluous.

You are going with a Fatal1ty board(ATX) but picked a case that supports only Mini-ITX...

I like http://www.corsair.com/psufinder/ to find the required wattage.

If your just playing games you are not going to put a dent in that CPU, go for SLi

That looks like a good PC

ASRock Fatal1ty Z77 Professional Micro ATX Motherboard, this is a micro ATX it say right there and if you do't believe it google it.

JonnyWhite89 :

The case still only supports Mini-ITX, so it wouldn't fit.

JonnyWhite89 :

I can read the OP well enough. The board is incompatible with the case. I didn't think I needed to spell out micro to get my point across but it appears that you have proved me wrong.

slomo4sho :

I do apologies, I completely miss read the spec of the case, you need an ITX Motherboard not a mini-ATX. On that note you can't go with SLi as I also suggested.... Sorry

JonnyWhite89 :

thanks for the help and i had later realised the problem and after your advice i have changed it to a gigabyte GA-Z77N-WIFI Mini ITX motherboard and chosen a VTX3D HD 7970 as the GTX 670 wouldn't fit. I have also chosen to use the hybrid modular corsair 600W buider series power supply. i am going to remove the 120GB SSD and use the 240GB on its own with a 750GB Seagate Hybrid SSD/HDD for saving my films on. Thanks for all of your help
