Antec HCG 750W: Built for Gamers?

| 20% | +2.40% |
| 50% | +1.40% |
| 80% | +0.60% |
| 100% | +-0% |
| 110% | -0.40% |
| +12V regulation (worst rail) | |
| Load | Voltage |
| 10% | +1.50% |
| 20% | +1.33% |
| 50% | +0.80% |
| 80% | +0.16% |
| 100% | -0.17% |
| 110% | -0.54% |
All rails are very close to the optimal value. They start with a small over voltage and end with results just under by 0.5% to 1.0%. Since this PSU has multiple 12V outputs we have selected the worst rail for the tables, as we always do. +12V is not too weak but we should keep in mind that our loads are 14A per rail, according to the ATX standard. This is far away from the rated maximum but more than enough to reach 750 watts output.
Ripple and Noise
| +3.3V ripple quality | |
| Load | Ripple and noise |
| 10% | 15mV |
| 20% | 15mV |
| 50% | 22mV |
| 80% | 27mV |
| 100% | 31mV |
| +5V ripple quality | |
| Load | Ripple and noise |
| 10% | 18mV |
| 20% | 19mV |
| 50% | 28mV |
| 80% | 33mV |
| 100% | 36mV |
| +12V ripple quality (worst rail) | |
| Load | Ripple and noise |
| 10% | 23mV |
| 20% | 29mV |
| 50% | 30mV |
| 80% | 34mV |
| 100% | 50mV |
The good results continue here. Both smaller rails have less than 40mV ripple and noise (50mV is the ATX spec limit). The +3.3V rail shows small transients and +5V has some negligible overshoots. +12V has higher absolute ripple, but as a percentage it's better than the other rails at only 50mV. While this power supply is no match for the HCP series, the price makes the difference and there's nothing to worry about.

Well, unless you have a windowed chassi you won't be seeing much of that PSU once you've put it all together.. I would never buy PC hardware based on looks either..Martin Kaffei - Friday, April 15, 2011 - link
In my opinion the look is just secondary.But I still prefer those black Corsair PSUs and would never buy a pink one. The aesthetic shouldn't be ugly.
But I agree the look of the PC case is more important than the appearance of a PSU, which is usually not visible in a closed PC.

Antec is freakin great company. And has with out a DOUBT ,the BEST customer service ive EVER seen. Me personally i chose this PSU for that reason. And they are VERY reliable quality and power! Im not sure why it didnt hit 80+ silver.Im useing it with
asus v formula
fx-8150
gtx 570 SLI
2 ssd,3 WD 320gb and 1 tb
h100, with 10! 120 tri-cool fans includieng the 230 bogboy! All with out ANY issues!
