Hey community I need help choosing a PSU I used the build from razethew0rld channel on youtube for a AMD FX 8350 but i changed some things and this is the part list

CPU: AMD FX 8350 Vishera (4.0 Ghz)
Motherboard: ASUS Sabertooth 990 FX R2.0
Memory: Kingston Hyper X blu (2X4GB)
HDD: Seagate Barracuda 2TB 7,200 RPM SATA 6.0Gb/s 3.5"
SSD: Kingston Hyper X 3K 120GB
GPU(2): AMD Radeon HD 7770 Crossfire

The Estimation on the Calculator was 510 w and for a newbie is that an accurate amount and should i go for a Higher wattage for the PSU

P.S. If you disagree with some of my parts and recommend something else put it down below!

550w -600w to be safe.

When looking at a PSU, just be sure it has at least a bronze certification, can't really go wrong from there.

Obviously don't go too cheap on the PSU, it's well worth having a good quality PSU as they usually last more than one system build.

I am also an avid viewer of RTW and Tek Syndicate, ;)

I would say the PSU calculator was accurate, in a X-fire system with 7770's NVidia suggests a 600W or greater PSU which is consistant with the calculator. I'm going to suggest looking at these two 650W PSU's as possibilities
Rosewill CAPSTONE-650 650W reviewed here http://www.anandtech.com/show/5698/rosewill-capstone-45... (conclusion page)
ENERMAX NAXN 82+ ENP650AWT B 650W 550W model reviewed here http://www.hardwaresecrets.com/article/Enermax-NAXN-82+...
The Rosewill seems to be the best for the $$
Hope it helps

reveiws on newegg are pretty bad.
i'd go with the rosewill hive but that's just personal preference.
you don't want to skimp on the power supply and do tons of research . i use newegg mostly to read reviews on that certain product .

You are going to get nothing but frustration with crossfiring 7770's.


I suggest you buy the single best gpu you can get.


You live near a microcenter?

When it comes to PSU's I prefer to use the professional reviewers found here
http://www.realhardtechx.com/index_archivos/Page541.htm If I don't find the PSU (or it's kin) there, with a passing (minimum) review I won't use it. The guys there really know their electronics and have the tools to see if the PSU can perform as is claims (many do not)
Hope it helps

I agree with avoiding Crossfire if you can. You will experience microstuttering and not all games even support multi GPU setups.

That being said you need a recommended 520w power supply for a system with 2 x HD 7770s. ( I agree with the Realhardtechx site being one of the best. )

http://www.realhardtechx.com/index_archivos/Page362.htm

Get a single HD 7850 or 7870 over the Crossfire 7770s if you can. Or even a 7950. I'm not up to date on my GPU prices without looking and I don't have time right now. Whatever the same cost single GPU solution is.

A quality 500-550w power supply will run any single GPU out there even the $1000 Nvidia Titan. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, Antec or thehigher efficiency Rosewill units for quality. Most certainly avoid low end crap like Coolmax. For a good low cost unit look at the Corsair CX series.


Personally if I was buying a new SSD ( and I will be in a month or 2 ) the only choice in my opinion is the Samsung 840 for value or the 840 Pro for max performance. Samsung drives are the fastest, most reliable drives on the market. With the 500GB 840 as low as $290 here lately I am going to have a hard time not getting one.

I Have a question what kind of problems will i encounter Crossfiring two 7770s? The initial reason i did this is because I have a 7770 right now and i wouldn't be that expensive buying another one and crossfiring it with the one that i have right now. Is it really that glitchy and problematic? It just be more exopensive buying a 7870. I would rather get a closer FPS to a 7870 and spend less money.

If you have one already then it makes sense but as I said above with Crossfire/SLI you get micostuttering and some games that don't even support multiple GPUs. Is it a good way to improve your frame rates? Yes. Is it as good as a single more powerful GPU? Usually not.

The OCZ ZT is a pretty good unit especially at $69. I don't see a similar quality modular unit for cheaper.
