fzlbayu · Oct 31, 2013

hi guys, i want some advice to buy a PSU whether 650w or 750w, im not an overclocker, i dont want to overclocking my CPU or GPU or anything else, here is my build:

CPU : i5 3570
Cooler : CM Hyper 212 Evo
GPU : HIS Radeon 7850
Mobo : ASRock H77 Pro4/Mvp
Ram : Corsair CMZ8GX3M1A1600C9 (1X8GB)
HDD : Seagate SATA III 1TB 7200RPM
Casing : Cooler Master K281 Gaming
Optical drive : Samsung DVDRW SATA
Monitor : LG 22 Inch 22MA33A LED TV

does Rosewill Hive is a reccomended PSU? i mean does it has a pure power?
and which PSU do i need to buy? 650w or 750w

what if i'm using i7 3770 for the CPU? does 750W enough for this?

thanks

I recommend using this PSU wattage calculator to determine what wattage you need.

I would also add an extra 100 watts or so just in case.

fzlbayu :

Why buy an aftermarket CPU cooler if you aren't going to overclock , just use the one which comes with the CPU?

either will do for that build, if you want to SLI/crossfire in future go for the 750w minimum

With the 7850 and no Xfire a good 500-550 is plenty, will want at least 21 Amps on the 12 volt rail - a good reasonable cooler would be the HYper 212 EVO, about $35, I don't have a lot of faith in the Intel coolers myself

For 210 on an i5 3570, I'd recommend an 8350 for 190 if you hadn't already purchased your other components.And RAM-you won't need more than 8gb if you're only gaming. But smaller RAM runquicker than so does dual channel. So I'd recommend 2x4GB. As for PSU, 500w is good, but if you might add to it for Xfire, I'd recommend maybe 650w. OC-Z makes some nice full modular ones for cheap, and this means better wiring

. Here's your build, and then my recommended:

The reason for extra wattage if you're wondering, putting a PSU nearly full load constantly decreases it's lifespan. So working a PSU at ~50-60% tops for 24/7, that PSU will outlive so many other PSU's. (That, and it won't heat up as much and a couple more reasons

)

does Asrock 990fx xtreme3 has a PCie 3.0 slots? from newegg that i have read the specification, it only has PCie 1 & 2, while my radeon 7850 need a PCie 3.0 slot

Jake Wenta · Nov 1, 2013

fzlbayu :

The only AMD motherboard with PCi 3.0 is the one I have. Asus Sabertooth 990fx/Gen3.0. But you don't need it, as nothing uses more than 2.0 bandwidth. It's more a marketing gimmick.
