Can you guys look at my build??

Solution
The CPU requires relatively little power. The graphics card is the biggest power draw for most PC's.

The R7-260X has a system requirement of a 500Watt power supply.

System Requirements
PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.
2X75 Watt 6-pin PCI Express power connector is required for CrossFireX™ system.
1X75 Watt 6-pin PCI Express power connector is required.
4096MBMinimum of system memory.
Installation software requires CD-ROM drive.
DVD playback requires DVD drive.
Blu-ray™ / HD DVD playback requires Blu-ray / HD DVD drive.
500 Watt Power Supply is required.
600WattPower Supply is recommended for CrossFireX™ System.

Solution
You should, but like terry said, it's your GPU that takes the most power. I'd suggest getting a 500W (NOT corsair CX series) PSU.

I suggest not buying a cpu cooler and using that money on a better case and PSU. You can overclock on the stock cooler pretty well.
 
Actually the R7 and R9 260x both call for a 450w PSU, I've run them easily on very good 400w supplies, however, that EVGA W1 unit isn't one. I would neither run that GPU nor overclock on that PSU. Just to run the cards I'd get something like the Antec VP-450, minimum, and not overclock, or a really decent Tier 1 or 2 unit of 550w or more if you do plan to overclock. The G3258 has to be SUBSTANTIALLY overclocked to be worthwhile, which will easily run your power consumption requirements up to the point where 500w is cutting it a little close.

I'd do something like this.

I did you one up and posted the link to the Tom's article where they HIGHLY overclock the heck out of that chip.

The Intel Pentium G3258 3.2GHz Dual-Core Processor is an entry level processor. It isn't a "K" type processor. Thus it is practically not overclockable.


No offense, but please do your research. :)

The Intel Pentium G3258 is INDEED overclockable. Just google search it and you will find countless posts on it.

It is news to me.

It was my understanding that the Intel processors (LGA 1150 & LGA1155) since Sandy Bridge were locked other than the K processors

And I haven't read anything on this processor since it was introduced as a low cost processor.


Read this then! :pfff:

Why? I'm not interested in liquid nitrogen. And the point has already been made about this particular processor.
