Sorry, are you talking about the SX600-G or the SX500-LG in your comment? confusedsmiley.png

Either way, I did end up going with the SX600-G. thumb.gif This may seem like a dumb question, but does anyone know if the fan actually ever goes back to 'fanless' after it starts up? My case allows me to take off a panel and I've been kind of monitoring to see what happens. It is fanless at startup, but, once it does start when things get intensive and the fan comes on, it never really goes back to fanless. Sort of weird.

That's normal behavior unfortunately. Once the fan starts it almost never shuts back off on its own.

Do you know if the SFX-L psus are the same way?

Also, does anyone know how much the 700W psu will cost when it releases and if anyone will release a 600w version?

I don't for sure on the other SFX-L units but I suspect they behave the same. All the SFX-L power supplies currently out are based on the same Sirfa design.

I don't think SilverStone has mentioned anything about price of the SX700-LPT. Supposedly there will be a Gold-rated 600W version that will come out after the 700W but there's no timeframe for that.

Can a Silverstone SX500-LG handle the following setup?

1. 4790K @4.5GHz (1.20V)
2. GTX 980 Ti close to 1500MHz core (won't be overvolting)
3. 8GB x 2 DDR3-2400 1.65V
4. 500GB Samsung 850 Evo (will add more drives in the future, but they all will be SSDs)
5. Asus Z97I Plus motherboard

I currently have a GTX 970 in the rig. I am wondering if I can replace it with a reference GTX 980 Ti without replacing anything else in the rig.

For those who might be curious, I couldn't get the fans on the 500W SFX-L PSU to stop after they started as well. So, same as the SFX 600W PSU. I've tried closing all my programs and just running a single window of chrome and still running after 15 minutes. Kind of disappointed, since I was hoping the only thing running in my case would be the CPU cooler (no case fans in mine) so it'd be almost silent when doing light stuff, but I guess an extra fan is survivable. Still, advertising it as a semi-fanless PSU feels a bit like a half-truth.

Here's a review from Hardware Canucks showing a full system load for various cards under 500W



Their test System is below for reference:

Main Test System

Processor: Intel i7 4930K @ 4.7GHz
Memory: G.Skill Trident 16GB @ 2133MHz 10-10-12-29-1T
Motherboard: ASUS P9X79-E WS
Cooling: NH-U14S
SSD: 2x Kingston HyperX 3K 480GB
Power Supply: Corsair AX1200
Monitor: Dell U2713HM (1440P) / ASUS PQ321Q (4K)
OS: Windows 8.1 Professional



Here's another review from PC world showing a full system load:



Take note the numbers above were taken using FURMARK which is notorious for putting crazy loads on a GPU which it will never go through from normal gaming!

Here's their setup:

Processor: Intel’s Core i7-5960X
Cooling: Corsair Hydro Series H100i closed-loop water cooler
Motherboard: Asus X99 Deluxe motherboard
memory: Corsair’s Vengeance LPX DDR4 memory
Case: Obsidian 750D full tower case
PSU: 1200-watt AX1200i power supply
SSD: 480GB Intel 730 series SSD
OS: Windows 8.1 Pro


So, he is right to say that the 500 watt PSU should be able to handle a swap from a 970 to a 980 Ti, even a non reference one!

Talking about semi-fanless mode of SX500 it mostly depends on rest of the components. In my case (I7-4790 + gtx 980, details here) it is really semi-fanless - the fan is off during internet browsing/playing video from NAS etc, even stays off during single cinebench run. It obviously turns on during longer load/games, and goes off again afterwards (5-10 mins later). During light usage scenarios CPU is around 1ghz or less and GPU is 135mhz (and ~8% TDP according to GPU-Z). So either I was lucky or I dunno... But that said - I don't like the sound of the PSU fan when it is on - very "clicky" and still "loud" during load, so I will probably get the 700 watt SFX L when it will be available.
