Hey Tom’s Hardware Community, I’m an absolute beginner and am building my first rig pretty soon. I believe I have practically chosen everything but the PSU.

I tried to use an online calculator and it worked out that I would need around 650w, so thought that 750w would be ample should I choose to overclock, run all my games at ultra settings or add extra fans. Was I right in thinking so? Is it enough? What would be the best 750w PSU I can get for under around $110?

I have searched numerous forums and read loads of reviews of different PSUs and was not sure which one to choose. I have found the following three options which both unfortunately have VERY mixed reviews on newegg and other sites.

Here is the rig I have chosen-

CPU - AMD FX8350 Black Edition 8 Core Processor (4.0/4.2ghz)
GPU - MSI N760 TF 2GD5/OC Twin Frozr (2 way SLI)
Mobo - Sabertooth 990FX GEN3 R2.0
RAM - Corsair CML8GX3M2A1600C9W DDR3 8gb (2 sticks)
SSD - Samsung 120GB 840 SSD SATA
HDD - Seagate 2TB 7.2RPM 3.5 6G/B SATA 64MB Barracuda XT
Optical Drive - LG GH24NS90
CPU Cooler - Enermax ETS-T40-VD Vegas Duo
Case – Either Coolermaster HAF XM mid tower case or Antec 1100 mid tower case (I thought these seemed best as they are very spacious and well ventilated. Any suggestions on which one, or which other mid tower cases (costing similarly), are better?)
PSU - ???

THANKS A LOT IN ADVANCE TO ANYBODY WHO CAN HELP ME :)  !!!!!!!

(PS: Is the rig above a good (gaming-wise) rig or not? I have never done anything like this and so would be extremely grateful for any advice I can get!!)

Best solution

I suggest the XFX PROSeries 750w, the same one as SR-71 Blackbird suggest, really good PSU and can't be beat at that price (i use this PSU in my 3570K Lan Party rig, i got mine for 60$ with 20$ Mail-in and 40$ instant rebate on NCIX)

out of that thread, SR-71 you have a nice signature !!

it'll be very fast, two 760 and a 8350 would run almost any game you want with max details (in 1080p)
August 6, 2013 9:39:44 AM

I will probably need to reduce my costs so I may only have one 760. Would it still be able to run 1080p without too much stress on GPU and other components + not causing too much heat?

Yeah, easily, a single 760 is enough for 1080p gaming, maybe you'll have some options down like AA and AF but it'll be playable no problem

Awesome- thanks Spawnkiller!!! I was really uncertain about the rig but now I'm really looking forward to it :D

I run 2x760 's with my FX8350 ,nice cards.

Are they both reference 760s or are they MSI, asus or gigabyte? I also understand you're using a Sabretooth 990fx GEN3.0 R2 motherboard? Apparently it's the only mobo with an AM3+ socket that supports PCIe 3.0

I have a revision 2 , and a GEN 3 , I have the 760's on the GEN3 , and a single 7870xt sapphire on the rev 2.

Wow nice :)  You must have a full tower case in order to fit two mobos?
