olly Posted February 8, 2008 Share Posted February 8, 2008 I wondered if I would be alright using my HX620 for either the 8800GTS512 in SLI or for the soon to be announced 9800GX2 (should be around the same power requirements as the 8800 GTSs in SLI). Also the rumored GT200 from Nvidia is supposed to draw 250W (Don't know 12V rail requirement) and has a 2x3 and 2x4 power connector. Does the HX620 support 2x4 power connectors? Edit: I should have read this thread http://www.asktheramguy.com/forums/showthread.php?t=59296 sorry, so It looks like the 8 pin connector is available on request, I might get away with 2 8800GTs or a 9800GX2 but perhaps not the GT200.

Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 The 6+2 pin connectors have come standard with the HX620 for some time now. However if you were to get a unit that did not have them for some reason, we could send them out to you. Link to comment Share on other sites More sharing options...

MU51CL Posted February 8, 2008 Share Posted February 8, 2008 This is a question that is going to keep cropping up as we start to see more cards with 8 pin power connections. As the HX PSU info on the Corsair website is not specific that 6+2 is now supported by these PSUs and the (now outdated) downloadable manual on the site says they have 2 x 6 pin, would it be a good idea to refresh that info on the website? This is a great feature of HX in the mainstream/enthusiast market - it pushed my buttons for sure! Let people know :): Link to comment Share on other sites More sharing options...
Willrob Posted February 9, 2008 Share Posted February 9, 2008 I'm not sure. I have the irritating problem with my Nvidia 8800 GTS (G92) card reporting that it is getting insufficient power etc. when I go into / out of standby. This card only has a single 6 pin PCI-E connector. According to the packaging it needs a 400W PSU minimum in non-SLI configuration (600W recommended) with 26 Amps at +12V. The HX620 offers triple 12V rails at 18A each with "Advanced circuitry design that automatically enable power sharing between the triple +12V rails in the event of overload on any single +12V rail" Now, if the 8800 GTS is drawing 26 Amps at a certain point in its power up / down cycle (ie when the fan briefly ramps up? - just a guess...) could it be the HX620 isn't responding fast enough? To be fair, there are lots of systems out there that appear to be exhibiting this issue and the common factor in all combinations seems to be the Nvidia card rather than the PSU or motherboard. A lot of people are suggesting it is an Nvidia driver issue. I am lobbying them (& XFX who make my card) too. Nonetheless, if this is is a shortcoming of common high-end PSU architecture it needs to be resolved! I see the TX series of PSU for instance are marketed on the basis of their 'dedicated single +12V rail' that offers 'compatibility with the latest components'. Hmmm! Lots of speculation I know but I - and many others - want to resolve this glitch. The HX PSU is beautifully quiet & well-made but if it hasn't got the muscle for a single 8800 GTS, then it's toast. Any feedback from Corsair? PS Are the TX series as quiet as the HX? (I know they are not modular cabling). Link to comment Share on other sites More sharing options...
EliteKiller Posted February 9, 2008 Share Posted February 9, 2008 I'm not sure. I have the irritating problem with my Nvidia 8800 GTS (G92) card reporting that it is getting insufficient power etc. when I go into / out of standby. Please see this reply from the Corsair Power Guy: http://www.houseofhelp.com/v3/showpost.php?p=329684&postcount=10 For those interested, NVIDIA has finally been able to reproduce the problem in their labs, and is working on a solution. As of right now, every major power supply vendor can potentially be affected by this problem. It is not tied to any specific brand or build of power supply. When NVIDIA has a solution worked out we will post it here. This card only has a single 6 pin PCI-E connector. According to the packaging it needs a 400W PSU minimum in non-SLI configuration (600W recommended) with 26 Amps at +12V. The HX620 offers triple 12V rails at 18A each with "Advanced circuitry design that automatically enable power sharing between the triple +12V rails in the event of overload on any single +12V rail" Now, if the 8800 GTS is drawing 26 Amps at a certain point in its power up / down cycle (ie when the fan briefly ramps up? - just a guess...) could it be the HX620 isn't responding fast enough? The 26A recommendation is the total system power consumption and not just the gpu. The G92 cards are not capable of consuming over 150W (12.5A) since they only feature a single 6-pin PCIe connector (75W max), and the PCIe slot itself supplies 75W max. To be fair, there are lots of systems out there that appear to be exhibiting this issue and the common factor in all combinations seems to be the Nvidia card rather than the PSU or motherboard. A lot of people are suggesting it is an Nvidia driver issue. I am lobbying them (& XFX who make my card) too.

I see the TX series of PSU for instance are marketed on the basis of their 'dedicated single +12V rail' that offers 'compatibility with the latest components'. Hmmm! Both the HX520 and HX620 feature a single 12V rail. Here's the response from the Corsair Power Guy: http://www.houseofhelp.com/v3/showpost.php?p=324422&postcount=5 You'll also find reviews (http://www.houseofhelp.com/v3/showthread.php?t=52612) where the HX series are tested and confirmed to have a single 12V rail. Lots of speculation I know but I - and many others - want to resolve this glitch. The HX PSU is beautifully quiet & well-made but if it hasn't got the muscle for a single 8800 GTS, then it's toast. I know many individuals running 8800GTX SLI with an HX620, and each of those cards can consume well over 150W under a load. In this special case the "glitch" has nothing to do with inadequate power, and more to do with some sort of timing issue. Any feedback from Corsair? PS Are the TX series as quiet as the HX? (I know they are not modular cabling). The TX series feature an excellent fan controller that keeps the noise under control. However in my experience the HX series are some of the quietest psu's on the market. Link to comment Share on other sites More sharing options...
