Does my build need a bigger PSU, for OverClock?

lilkev2477 · Sep 17, 2013

AMD FX-8320 3.5GHz 8 Core
8MB L2 Cache
8GB DDR3 1333
2TB SATA II 3.0Gb/s 7200RPM
24x DVD+-R/+-RW DUAL LAYER DRIVE
AMD Radeon HD 7770 1GB
MSI 760GM-P34FX MOBO
Thermaltake Purepower ATX 12v 2.2 350 WATTS

I Ordered a 212 EVO Fan and Heatsink , and two more fans ( currently have 3 on the case ), will be installing them tomarrow.
My Question is this PSU good enough for the extra fans , plus a goal of 4.5 maybe a little more OC on the CPU? Also an OC on the GPU ?

lilkev2477 :

Most likely. At 4.5Ghz you will be pushing 175-200 watts on the CPU. Tack on another 80 watts for the GPU and you'll be at up to 280 watts on those two components alone. Toss in the rest of the junk on the 12 volt rail and you have very little overhead on an already mediocre PSU.

Ok , kinda what i was thinking. Any Suggestions as far as Watts needed and a good PSU for my setup? I dont need top of the line , just something to do my planned OC .

Those psu's are pretty generic as far as performance I would get a 430w 80+ bronze psu if you want a stable system that can also handle your overclocks amd's take a lot of power to run and overclock http://www.newegg.com/Product/Product.aspx?Item=N82E16817139049

Leaves room for a solid PSU down the line

Nice! I did not think about " Future upgradability " ( new at this ) . So 550 W, atleast a Bronze Series, will cut it ? Im a bit concerned about anything smaller. Unless im just thinking im going to be pulling alot more power, than i actually am ..
Ive heard of Corsair being good, but havent heard of XFX .

if you plan on getting a large video card just get something like a 630w+ psu, http://www.newegg.com/Product/Product.aspx?Item=N82E16817139040 this is a 750w psu which will allow you to run crossfire and sli if you ever chose to and it has an amazing 62amps on a single 12v rail which will be able to handle anything you toss at it unless you build a crazy $4000 system

lilkev2477 · Sep 17, 2013

Ok. Thanks for your help. I will Consider my options and leave an update on witch one i go with.

What would be the difference between that Single Rail , vs a 4 Rail ? http://www.newegg.com/Product/Product.aspx?Item=N82E16817341041 Also like it because it will match my Setup ( Red ) .

single 12w rails just are way more better I've had single double quadruple rail psu's but I just find compatibly is just more there with the single 12vrail psu's solutions like I run my 2 gtx 770's in sli with the same power supply no problem overclocked and I have 2 ssd's 2 hdd's and about 7 fans and a water cooler works great
