First Time Gaming Build - PSU Advice


Just wanted some advice on a PSU for our first attempt at a Gaming PC build. We were looking at this one but not sure if it's best to go for a 750 or would that be overkill?

These are the specs so any thoughts on these too or any advice would be appreciated!!


Intel - Core i7-7700K 4.2GHz Quad-Core Processor

CPU Cooler

Cooler Master - Hyper 212 LED 66.3 CFM Rifle Bearing CPU Cooler


MSI - Z270-A PRO ATX LGA1151 Motherboard


Corsair - Vengeance LED 16GB (2 x 8GB) DDR4-2666 Memory


Seagate - Barracuda 2TB 3.5" 7200RPM Internal Hard Drive

Video Card

Gigabyte - GeForce GTX 1080 8GB WINDFORCE OC 8G Video Card


NZXT - S340 (Black) ATX Mid Tower Case

Thanks in advance :)

  2. Cheers for the quick reply.

    We've already bought everything except the PSU and HDD but thanks for the suggestion. Hope what we've bought is ok?!

    As for the PSU, a 550 would be enough then? Also, will adding an SSD make a massive difference?

    Thanks again

    Ssd is mainly to improve the loading times.
    Yes, a quality 550w psu like I suggested above is enough.
    Regarding your part lists, the mobo is a very basic z270. The ram I would choose is either 3000 /3200mhz model and the windforce oc isn't factory overclocked very much.
    Also, the 212 cooler is a poor choice if you even think of overclocking. It will do for stock speed cooling.
