SilverStone Starts Shipping the SX700-G SFX Power Supply

[btarunr]

SilverStone began shipping the SX700-G, the most powerful power supply in the SFX form-factor, with a nameplate capacity of 700W. This unit is designed for compact builds with bleeding-edge hardware, including up to two high-end graphics cards. Its fully modular cabling includes four 6+2 pin PCIe power, one 4+4 pin EPS, a 24-pin ATX, six SATA power, three Molex, and a Berg. Under the hood, the SX700-G features a single +12V rail design, with 700W output rated just for this 58.4A rail; and 110W for the +3.3V and +5V rails. The unit boasts of 80 Plus Gold efficiency.

Besides active PFC, you get most common electrical protections, against over/under-voltage, overload, overheat, and short-circuit. Keeping things cool is a 92 mm fan with fluid-dynamic bearing, with a minimum noise output of 18 dBA. SilverStone will first release the SX700-G in North America around mid-December, with availability in Europe following two weeks after that. In the US, it will be priced at USD $159.99, AUD $179.99 Down Under, and 139.99€ (excluding VAT) in the EU.

700W, 80 Plus Gold certification, fully-modular design, SFX form factor & a US$160 price tag. Sounds like a good investment in getting into mITX builds for me.

mITX builds

700 W is definitely overboard for a single CPU and single GPU build, which mITX suggests. Heavily overclocking on of the new 18 core 2066 CPUs together with a beefy AMD GPU might get you close. For a sane mITX build, I'd suggest something in the 550 to 600 W category, the 450 W Corsair for a tame build. There is also a 650 W Silverstone unit available for 120€ incl. VAT, which should be enough with a reasonable price tag.

Minimum noise of 18db? Well thats not very informative... what's the maximum??

Even with higher end parts my 6700K/1080 MITX rig runs on an ancient 450w just fine.

I don't know thr maximum noise, but it doesn't bode well for a quiet build... Might wait for a Cybenetics test.

@Deathy I would still use that PSU coz headroom is essential. You wouldn't know until you start cramming power-hungry cards.

Which card specifically needs more than a 450w SFX unit? I actually pulled my Vega FE card off of the 450w SFX I have in my HTPC, it's also had a 1080Ti in it without issue.

We are waiting for evaluation samples so into the next month it will be included in Cyben's database.

The PSU I'm really waiting on now is the rumored 700W Corsair SFX Platinum with two EPS ports. Although good to see more SFX PSU's overall. Even if my case can handle it, I don't really want ATX anymore. I love the design of higher power in a smaller package (density).
