I wouldn't buy it. Not only do I not recognize this brand, but its +12V capacity is 384W which means that this is a 520W peak-rated unit. So with a 384W +12V capacity, it's better to think of it as a 400-430W power supply (and probably not a very good one at that).
This PSU's +12V capacity is also only approximately 74% of the total wattage rating. As one rule of thumb [of many], avoid PSUs that have a +12V rating of less than 80% of the total wattage rating.
There are better PSUs out there than Corsair's CX "Builder Series".
For example, all of these are better:
- 450W Antec Neo ECO for $59.00
- 520W Antec Neo ECO for $69.00
- 520W Antec High Current Gamer for $85.00
I'm not recommending Antec, but instead I'm recommending these specific units. To be honest, the brand name is almost always irrelevant unless it's a brand I've never heard of (especially if its +12V is less than 80% of the total wattage rating, such as just 74%).
I'm sorry that I didn't shop anywhere else, but I looked at a couple of the other stores mentioned in that thread, and all I found were higher prices. I also didn't shop on Amazon.com because for some reason I have a bit of difficulty sorting through power supplies on their site.
By the way, what is your budget for the PSU?
