Cables and Connectors

The cable sleeving for most strands is made from a very cheap material; however, even cheap sleeving is better than nothing. You can see the yellow cables up top that support the CPU and graphics cards. They are very long for a PSU in this price range, which is useful for cases with bottom-mounted PSUs. Even if this PSU has no modular cables, the extra length means you can better route the cables to keep your PC looking tidy. There are also fewer cables with the 520W PSU compared to the 750W version, so it should be easier to tuck any unneeded cables out of sight.

Cables and Connectors
Fixed Main 24-pin 55cm
ATX12V/EPS12V 4+4-pin 60cm
PCIe 2x 6/8-pin 50 +15 cm
Peripheral 3x SATA 55-85cm / 3x SATA 55-85cm
3x Molex 55-85cm / 3x Molex, 1x FDD 55-100cm

Seasonic is the master of long cables and it seems to continue here since they are the ODM for this PSU. These aren't the longest cables we have ever seen but the length is nice for an affordable 520W PSU like this one. Keep in mind that the cost of a few extra cables and connectors can quickly add up, so every connector more than the competition brings added value. The HCG-520 provides six SATA and Molex connectors, along with one FDD plug. The only complaint we have is that both PCIe connectors share one cable with a common wire cross-section. We wouldn't recommend such a setup for the highest power GPUs, though of course both AMD and NVIDIA recommend more powerful PSUs for products like the HD 6970, HD 6990, GTX 580, and GTX 590.

    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
