post #1 of 9
Thread Starter 
I'm getting a new build and want to know if a 660 watt p/s would work,
Build is:

i7 4770 with a H80i
Asus Sabertooth
8gb Corsair ddr3 1600
Gtx 770
1 WD 500 gb. HDD
1 Samsung SSD (bootdrive)

All in a FT02 so around 5 fans (3x180, 2x 120)

the p/s will be a Silverstone SS-660XP2

You're only going to be using 400w with that build. I would suggest getting a 550w power supply unless you plan on future video card expansion.

The Capstone 550w, the Hive 550w, and the XFX Core 550w would be excellent choices.

According to this, your total wattage estimate is around 430W

Honestly, I think you should get at least a 650W PSU, since you might you want to overclock it and for future upgrades, such as a 2nd GPU.

The Rosewill Capstone is still the best bang for buck you can get

At least what i know of

IMHO you won't be getting 400W, you will be getting less (wall consumption), even with overclocks on both CPU/GPU.

I would still go with a quality 650W class unit, not only cause it will allow for some headroom for future espansion (i.e. 2nd 770 or some beastier solution by nVidia ala GK110 or - why not - a Radeon 9xxx card), but also because PSUs are usually more efficient around their 50-60% load range.

Ofc, in reality you will be seeing your max wattage being pulled only if you fold on both CPU/GPU at the same time or something equivalent. Your real wattage consumption, especially without a heavy overclock would be in the sweet spot for a 500-550W PSU. When gaming, I doubt you will often be pulling north of 300Ws.

Build uses fare less power than people think but it really doesn't matter bigger is better as long as you get the highest efficiency on your socket voltage.
Platinum for you that would be for me it would be something that only dell makes so I pretty much cling on to anything Gold or platinum as long as it is 90%+ I'm fine with it.
You have about 380W of in terms of max power consumption there the 770 won't have that much OC potential left as it is reference overclocked.
I would advise a 450W psu or any wattage with gold/platinum efficiency.

If you go with the 650w, then you can get another GTX 770 later on and not upgrade the psu. The 550w is fine for the single GTX 770 system, although all you need is 500w max.
