Antec HCG 750W: Built for Gamers?

Like most Antec PSUs this one gets very loud once we near 100% load. However, most PCs don't (and shouldn't) reach that level so the sound pressure during low to moderate loads is more important. Most "gamer" systems also have GPUs that generate a lot of heat, so an active cooled PSU is very welcome here. At a load of 50% (~375W) or less, the HCG-750 is nearly inaudible in a closed PC; 20 dBA is almost certainly less noise than most GPUs will generate, and they would likely be necessary to reach such a load.

We have two different charts for efficiency and PFC, as some readers expressed interest in 230VAC measurements. The efficiency is good for an 80 Plus Bronze PSU, reaching up to 86% on 115VAC, though our 81% result at full load on 115VAC is actually slightly below the required 82%. More importantly, we see greater than 80% efficiency at low loads, which isn't always a given even with high-end power supplies. PFC is also good on 115VAC. As is always the case, on 230VAC PFC drops quite a bit and we'd like to see better results. On the other hand, efficiency on 230VAC goes up several points, easily qualifying for a Bronze rating and nearly reaching Silver levels. Not bad for a moderately priced PSU.

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!
