Need advice on PSU to get for my build..

post #1 of 10
Thread Starter 
Its been awhile since I've built computers (I'm switching back to Windows after being in the Mac world for a couple of years) and I don't know how much wattage I will need for my new build.

Here are the specs:
MSI P67A-GD55 (B3) LGA 1155
SAPPHIRE Radeon HD 6970 2GB
Intel Core i7-2600K
G.SKILL Ripjaws X Series 8GB DDR3 1600
Western Digital Caviar Black 1.5TB
COOLER MASTER Hyper 212 Plus
NZXT Phantom Black - it comes with fans

I was thinking of getting this PSU:
ENERMAX REVOLUTION85 920W

But I'm not sure because I kinda think a 920watt would be over kill. Would it be? How much power would my system need/use?

Any recommendations of a good reliable power supply would be much appreciated.

I strongly recommended it, I've owned one for about four months and it is THE best PSU out there right now. I got mine on sale for $129.

Your build is very similar to my current one.

All SeaSonic built PSUs are gold. 920W is seriously over-kill, though. For your build, if you want to consider CrossFire later on, I wouldn't hesitate at all to recommend the Corsair TX-750v2, especially at its current price of $105. A very solid SeaSonic made unit. If you want features like semi-modular cabling, you can pay a bit more and get an Antec TruePower New 750W for $130. If you want a fully modular one, get the Corsair HX750 for $140. This is as high as I'd recommend you go for your build if you don't want to waste money. Even with tons of peripherals and CrossFire none of these units will break a sweat.

I sense the approach of a Phaedrus who will tell you that rig would run on a good 500w or possibly a 450...
Seriously, an ax750 would run a pair of those GPUs and more.

550w would be fine on that rig, But i'd go with the TX650v2 unless you're planning on a second 6970.

Pretty much what compuman said

No need for 750w. Something more around 600W will be MORE than enough for that rig.

You won't need more then 550 or 650 watts with that rig, if you plan on doing crossfire later on though you might want to pick up a 750.

I usually leave a little headroom, I would go with a 650 watt one. Go for Corsair, Antec, or XFX brands. Just look for the best price, MIR, promos, combos, etc, and go with that one. Just make sure it has all the connectors you need, those brands will generally have enough amperage on the rails as well so you won't need to worry about that factor.
