I'm looking at a build ,but I can't decide on a power supply that will not only work now, but in the future for a few more add ins. The two power supplies I'm trying to decide between are the 1,200 Watts - Cooler Master Silent Pro 80 Plus Gold Power Supply and the 1,000 Watts - Cooler Master Silent Pro 80 Plus Gold Power Supply. Any help would be appreciated. The system specs I'm looking at include:

12in Liquid Neon light
1 fan 200 mm fan,
1 140mm fan
3 120mm fans (all 5 of these fans have leds in them)
i7-3770K
Thermaltake Frio OCK CPU Cooler
1 HDD
1 SDD
EVGA NVIDIA GeForce GTX 670 FTW
24X Double Layer Dual Format DVD+-R/+-RW + CD-R/RW Drive
1 thermal display
8 gb RAM
GIGABYTE GA-Z77X-UP4 TH Intel Z77 Chipset

Thank you in advance

Both PSU's are overkill for your planned system. A GTX670 FTX should not pull more than about 15 amps (180 watts). A good 650 watt PSU with 50 amps at 12 volts output will be more than adequate.

For your system, I would suggest either a Corsair TX650V2 or XFX 650 watt PSU. Both are built by Seasonic and are very good PSU's.

Not sure why you're looking at those PSUs.1. CoolerMaster makes iffy PSus. 2. The ones you chose are way overkill for your system, even if you should decide to SLI later on.

Look at a Corsair 750 Watt Enthusiast series PSU, either modular or not as you prefer. Your pocketbook and peace of mind will thank you.

CM has started to make some decent power supplies recently, but I never can remember which models. So I avoid all of them and just stick to what I know are good PSU's.

Thanks jsc and abekl for replying so quickly. Looking at these particular power supplies they seemed to good value for the watts (,but I'm new at this). I didn't realize I was so out of the ball park for what I needed, thank you for letting me known (and giving me peace of mind that) a smaller psu will be fine. I do have a further question thought, do Corsair's power supplies have a lower failure rate then Cooler Master's power supplies as a general rule of thumb?

Absolutely. Corsair PSUs are very reliable. Much more so than CoolerMaster.
