Hello all,

I'm currently in the process of acquiring parts to build my first gaming PC. I've been using PSU calculators around the Internet but different sources give me different results. I was hoping someone here could better advise me.

My proposed parts list is as follows :

CPU : Intel Core i5-4590 Haswell Quad-Core 3.3GHz LGA 1150 84W Desktop Processor Intel HD Graphics 4600

GPU : Gigabyte R9 270X GDDR5-2GB 2xDVI/HDMI/DP OC Graphics Card

Motherboard : Gigabyte GA-Z97X-SLI LGA 1150 Z97 2-Way SLI UEFI DualBIOS ATX Motherboard

HDD : Seagate Desktop 2 TB Solid State Hybrid Drive SATA 6 GB with NCQ 64 MB Cache 3.5 Inch (possible additions here)

SSD : Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive

RAM : Corsair Vengeance 8GB (1x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory

CASE : Cooler Master N400 - Mid Tower Computer Case with Fully Meshed Front Panel

HEAT SINK : Cooler Master Hyper 212 EVO

I appreciate whatever help I can get.

Anywhere from 550-700w is good

You should go for around 650w. That build will use around 500w, so 650w will be perfect, especially since it will leave you some headroom

Going off on a tangent here, but is there a reason you're using only one stick of RAM?

You'll be losing the benefit of dual-channel memory.

  • eXtreme Power Supply Calculator Lite is fairly decent.
  • If you are certain above list is complete for the system and will be using a decent power supply, a 500w should do.
  • If using typical/budget power supplies, suggest you follow Sheepzorable's suggestion.

Thank you for the replies. I've been looking at a Corsair CX600. What do you think about that?

I'm using 8GB now with intention of getting a matching 8GB later on. I've read up a bit on dual-channel and though it does offer improvements, they're not generally improvements in areas I'm looking at at the moment (mostly gaming).

I've used xTreme and it gives me a value of around 420W. I've just seen my GPU's power requirement of 500W on Gigabyte's website. What should I make of that?

The CX series is classified as a budget model. It is lowest Corsair model in their lineup.

If you can eke a little more out of your budget buy a better one than that. Even from Corsair. It's their budget line and is at the lowest end of the scale. And going modular or even semi-mod will pay off in the future with cable mgmt.
