Voltage Regulation
+3.3V regulation | |
Load | Voltage |
10% | +1.21% |
20% | +1.00% |
50% | +0.72% |
80% | +0.43% |
100% | -0.30% |
110% | -0.38% |
+5V regulation | |
Load | Voltage |
10% | +1.20% |
20% | +1.16% |
50% | +0.85% |
80% | +0.60% |
100% | +0.29% |
110% | -0.40% |
+12V regulation (worst rail) | |
Load | Voltage |
10% | +0.75 % |
20% | +0.64 % |
50% | +0.40 % |
80% | +0.27 % |
100% | +0.11 % |
110% | -0.08 % |
All the rails fall clearly within ATX specifications. They start slightly over the target voltage and end with results close to 0%. Since this PSU has two 12V outputs, we selected the worst rail for the tables (which is our standard procedure). +12V shows the best regulation, and will have no trouble with higher voltages. -0.08% at overload is one of the best results we have seen.
Ripple and Noise
+3.3V ripple quality | |
Load | Ripple and Noise |
10% | 13mV |
20% | 14mV |
50% | 18mV |
80% | 22mV |
100% | 23mV |
110% | 25mV |
+5V ripple quality | |
Load | Ripple and Noise |
10% | 9mV |
20% | 11mV |
50% | 16mV |
80% | 18mV |
100% | 19mV |
110% | 21mV |
+12V ripple quality (worst rail) | |
Load | Ripple and Noise |
10% | 8mV |
20% | 12mV |
50% | 14mV |
80% | 26mV |
100% | 28mV |
110% | 33mV |
Both smaller rails have less than 30mV ripple and noise, making this PSU is as good as the Antec HCG if not better. +12V has higher absolute ripple, but it's actually closer to spec as a percentage. All of the rails are far away from the limit. The TX750 V2 can't beat the Corsair AX 750W, so we now know why there is such a high price difference. Of course 80 Plus Gold is another reason to buy an AX-series PSU.

The review really seems to jump into things with no intro.JarredWalton - Monday, May 16, 2011 - link
I thought I had copied over Martin's text from the front page summary, but I apparently didn't. It's not on the first page.quiksilvr - Tuesday, May 17, 2011 - link
I hate to be a grammar Nazi but please change the title. How can something be new AND improved. It's either an entirely new product or an improved or upgraded version of its predecessor.JCheng - Tuesday, May 17, 2011 - link
It's a newly released iteration that improves upon the previous iteration.Etern205 - Wednesday, May 18, 2011 - link
It's "new" as it just came out and "improved" since this is marked as version 2.Stop nitpicking.

And stop ripping off George Carlin...quiksilvr - Wednesday, May 18, 2011 - link
So if a comedian points out an oxymoron it's called ripping off? I'll keep that in mind.ekstor - Thursday, May 19, 2011 - link
Technically, you're not actually pointing out a grammar issue.Mathieu Bourgie - Monday, May 16, 2011 - link
I quickly read the article, but I didn't see any mention of how well the TX750 V2 does compared to the its predecessor, the TX750?What are the pros/cons of going with the V2 compared to the original?
Otherwise, great review, thanks!

Same here. I was really looking for some comparison to the TX750 "V1", the original one.
