Appearance and Fan

The black finish is pretty typical these days, but the red accents add a nice touch. The fan grille also mixes things up by using a slight octagonal cutout. The ventilation holes at the back are honeycombed and there is a small power switch beside the AC inlet. At 160mm in length, this is a relatively small case and will work well in smaller enclosures. Personally, I think the design of this model is more professional than that of the HCG-750, so hopefully Antec continues to use this design.

ADDA  is an often used company that delivers decent fans for power supplies. This ball bearing type has the model number ADN512MB-A90. This 135mm fan can spin at up to 1700RPM, so it shouldn't get too loud. The nine fan blades are well-made but overall it won't be able to surpass a Sanyo Denki fan.

    No sooner did I read Anandtech's reveiw of the Antec HCG-520 than my home pc died. Figured it was either the p.s. or the motherboard.

    Ordered the HCG-520 from the egg late last week. Received it today, installed it and my pc came to life. I'm impressed w/ sleeving and cables for a budget p.s., as well as its low noise level.

    Hello, i had this PSU for 6 months now in its box, and i am going to put it in a new system in one hour or two, and this is why i glad i run into your review.
    But first things first, very nice review!

    My problem is that my XFX 6950 asks for 2*6 pin 75W connectors, and specically says NOT to use a Y connector or anything else, it wants 2 cables while the PSU has only one.
    So the question is, should i connect both, or use a connector on a 4pin molex to get the job done?

    Thanks in advance
