Corsair CX750 vs. TX750

[Paull]

I'll buy one of then, but I have doubts regarding the cost benefit.Do someone know what exactly is the difference between the two? I know that both are 80+ Bronze certified. What makes the "TX" more expensive than the "CX"?

Thanks

Just have a look at the tech specs, the TX has more connectors. It all comes down to how many and what sort of components you need to feed. I guess you're having many devices, else you wouldn't look for a 750W one. Both are non-modular, I could imagine the cable management to turn out a little messy.

E: Warranty is also different.

Thanks Rusch.

I'll feed an Core i5 2500, 8GB RAM Corsair Vengeance, ASUS P8z77-v and maybe an 2-way SLI of GTX 660.

The CX750 is enough, right?

[Rusch69]

To make it short: Yes, it gives enough power.

Look up your GPUs' power supply though. It could possibly differ from the usual 1x 6-pin, depending on the manufacturer and clocking/memory.

Just select what you have and it'll roughly tell you what it needs all together. I guess it'll be less than 750W, so ya can possibly go with something weaker and spare money unless you consider more upgrading in the future.

First of all, CX series is the weakest PSU series made by Corsair. It's lifespan is lower. They are pretty good, but you might end up having some energy problems, or lack of reliability in about 1 or 2 years.

TX series is some what enthusiast, it's efficiency is higher and they last for a longer time than CX.


You could always check Tomshardware for what products are recommended and what products are a trap. Either way, I wouldn't buy any of these. I'd go with a ZT from OCZ, Cooler Master or Antec.

Reason? I had several PSUs made by Corsair, and most of them, lasted for less than 2 years. And I can asure you that they had a higher wattage than the recommended for my previous system. No to mention that they are noisy as fuck.


My true recommendation is OCZ.

I've only had good experiences with Corsair (HX1200W, HX1000W and a 800/700W-something) and with OCZ too.
Use this calculator to find out how much power you need then either get the one that delivers the most power (1000W for say 200USD) or the most high-end version that delivers just enough (700W for the same prize). Link: http://www.extreme.outervision.com/psucalculatorlite.jsp
All PSU's power output has a continual drop in power output as time goes by so you either want a mediocre 1000W that drops to 700W in 2 years or a 750W psu that drops to 700W the same amount of time.

[Paull]

Yes, I know that Daffy.

My only doubt was the difference between "CX" and "TX", now I know the TX is basically better so in terms of efficiency, voltage regulation, ripple levels etc

I'll choose the CX because of the cost benefit.

Thank you guys
