Upgrade Advice, Help appreciated

[trunks91]

I am currently in the process of basically re-doing my entire set-up.
I've been using a 500W Antec [Fairly ancient] PSU for quite some time now.

My current system is basically (In my opinion) a quite low tech budget build consisting of the above mentioned PSU and the following...

MOBO - Asus M5A97 R2.0 [Latest BIOS]
GPU - Asus 2GB Dual Fan HD 7770 [Not Overclocked]
RAM - 16 GB Cosair Vengeance [4x 4GB Sticks]
CPU - AMD FX6300 6-Core Black Edition [Currently Overclocked to 4.3 GHz] [Great temps, Stress tested etc Stable]
HD - 2TB Seagate Hybrid Drive
Cooling - Multiple Cosair fans, 1 Exhaust, 2 Side panel intakes along with a front panel intake.
CPU Cooling - Zalman CNPS5X

So yeah, Basically I'm looking to improve my system for gaming I currently have my eye on a
Corsair Builder Series CXM 750W Modular 80 PLUS Bronze Certified ATX/EPS PSU and a new case to go along with it, Corsair Vengeance Series Black C70 Mid Tower Computer Case.

I'm planning on buying 2 new GPU's for a dual setup, I can't see myself getting a new CPU anytime soon to be honest. The motherboard I'm willing to upgrade to maximize Crossfiring capabilities and I've also been thinking about fitting an SSD as well.

I suppose my main question would be is the PSU I have my eye on a good option for Crossfiring up two decent GPU's? From what I can find online the power output of the Cosair PSU I have my eye on is as follows..
+3.3v @ 25A
+5v @ 25A for 130W across 3.3v and 5v combined.
+12v @ 62A for 744W max
-12v @ 0.8A for 9.6W
+5Vsb @ 3A for 15W

Any advice whatsoever is welcome.
I'm just really looking for a bit of guidance to be honest, I've only built a PC from scratch twice and to be quite frank I'm a novice at best when it comes to picking out parts that will work well together and give me a good solid Gaming PC. I'm not looking to spend a fortune and I live in the UK.

Again, Any help or advice is much appreciated, Thank you.

Your system isn't that bad, but you might not be able to upgrade to a dual GPU setup without upgrading the CPU to a high-end Intel and I would be cautious about using any of the Corsair PSUs... they're all outsourced and most of them aren't very good.

Regarding a new CPU for Dual GPU's is AMD totally out of the question or would an Intel i5/i7 for example basically just maximize the potential? Intel CPU's from what I can find online tend to be quite expensive. Nothing I can't afford just way beyond what I could justify to the missus lol. I'm not a massive gamer or anything basically I just want a nice solid rig for when I am gaming, that's more or less what I'm after.

Regarding the PSU, are there any good ones around for say, Under £100 that would do the job with Crossfiring?

Cheers

In general it would just maximize the potential, if you can find someone who has tried it before then you can find out how big the difference is.

"Corsair PSUs... they're all outsourced and most of them aren't very good."?? wow...ok...
Anyway, regarding the PSU , i have the same one and i don't have any complains about it but for a SLI/Crossfire is out of the question. You really need to get a better PSU for it , try something above like HX/AX series.
I wouldn't change the cpu since its still a good one but just a little bit power hungry compare with to the intel side.
Going with a crossfire hf 7770 is a huge mistake however because its outdated GPU and you would be much better with trying to sell it and going for something newer like a r9 280x/285 or even a GTX 970 and for that you could keep the cx 750m

I was planning on buying new GPU's for a Crossifre setup, I know the 7770 Is fairly outdated now 😛
I'll have a look at some of the better PSU's regarding a Dual GPU setup, Thanks mate

Sorry, I didn't really provide a lot of info there, my point was that Corsair doesn't make their PSUs so you have to check who does make them + reviews before making a decision. Some of their models are good, however there is a lot of variety and even if you buy a "bad" model you may not have any problems with it but it's all up in the air. It's just a lot easier to buy a decent model from a known good manufacturer that does their own construction/research in house.

So after looking at the thread on here regarding PSU's and Tier etc
I did a little search on Amazon and came across this PSU

Corsair CP-9020073-UK Professional Platinum Series HX850i ATX/EPS 850W Power Supply Unit

It's well within my price range and according to reviews it's pretty damn good, thoughts? I imagine it would do the job of crossfiring without issue.

 

[Joao Machado]

yes , that is a good PSU and will do fine with Crossfire/SLI
