500 WATT PSU? for new build


Jan 31, 2008
Hello, Seeking some advice...
I'm considering this build in a Thermaltake Lanbox case I currently have. All the research I have done says the components will work well with each other but I am concerned about the PSU. Will 500 watts cut it? I will not be overclocking. Also add a standard DVD burner I currently have.

1. ASUS Maximus IV Gene-Z LGA 1155

2. ZALMAN ZM500-HP 500W

3. Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) 4 x 256KB L2 Cache 6MB L3 Cache LGA 1155 95W Quad-Core Desktop Processor

4. G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 x2 (8gigs total)

5. Scythe SCSK-1100 100mm Shuriken Rev. B 3 Heat Pipes CPU Cooler

6. Video Card will be an existing MSI NX8800GT 512M OC GeForce 8800 GT 512MB

Thanks in advance!

Umm can I assume that this is for gaming? If so, I have a few recommendations to make.

First, the Maximus 4 Gene-Z is unnecessary since you will not be overclocking. If you are intent on Micro ATX can i suggest simply getting a P8Z68-M Pro instead? alot cheaper and all you will need since there is no O.C. involved.

I would also recommend upgrading from 2x2GB to 2x4GB RAM. People may there isn't a performance increase but Windows will tend to use less SWAP when additional RAM is installed, allowing system critical function to work faster, which games may need.

If you are not overclocking, the stock heatsink works absolutely fine unless you are really intent on getting something that is much quieter. I used the stock on an i7-2600k untill I decided to O.C., but my Case Fans are really loud and pull air around fast so I would not have noticed much.

And, can I recommend I much Better Video Card? Like an NVIDIA 560, from ASUS or EVGA.

Also, you should look into a more reliable PSU company, i prefer Corsair. 500 Watts should do fine in this setup, but I would I highly recommend 650, especially if you take my GPU card recommendation.
a 2500k is a 2500 with an unlocked multiplier so you can overclock .
Save money , buy the 2500 instead .

If you already have the graphics card and think updating mb/cpu/RAM will give you a boost in games performance you are almost certainly wrong .
Unless your current processor is a pentium 4 or a low end core 2 duo the limitation in your system is the graphics card .

500 watt quality psu will run it easily . A poor quality 500 watt psu will explode and burn your house down
