Conflict with the PSU.

[Chrono Trigger]

I have a problematic situation, according to friends of mine who also have this motherboard my power supply is not compatible (well on paper it is but this is an exception) with the motherboard. I have an Enermax Liberty 500W which conflicts with almost every DFI board in the ATX-plug. He said that it wasn't a matter of wattage capacity but it had something to do with communicatin signals between the PS_ON and PWR_OK pins which could explain why my computer is not rebooting anymore. Not all of the Diagnostic LEDs burn anyway, the last one (the system start-up) signal is off. This friend of mine who also had an Enermax psu and an rdx200 replaced it with a Seasonic S12 500W and it worked again perfectly, for the I want an OCZ PowerStream 520W, but he also said that there are more ATX2.0 psu's which do not comply with this board. Is there a list opf psu's which are compatible with this board?

This is a sticky of PSU"s that work with DFI boards, stick to the A list and you should be fine.

700watt> http://www.fsp-group.com/english/1_product...id=98&proid=462

 

Those two are all I recommend anymore. Sure there are quite likely others, but I do not have time to speculate about which ones they are. So many manufacturers are behind the times in building power supplies and updating to ATX spec when ATX spec does not even go beyond 450 watts at this time and we are needing 500 to 800 or more 'working' watts for the power hungry boards, cpus and these freeken ultra power hungry new video cards.

 

So there will 'not' be any list of truly current recommended power supplies for that board; because what IS available is changing too too fast and what "was"; is superseded by what is now.

 

I have used both of those supplies on my RDX200; Expert and the Venus board and they both have worked fine to 'start/crankup' the boards WHEN you pay attention to balancing the load on all 4 12Volt rails so the later 'type' power supplies can put 'out' fully. If you have 'only' one video card then pay attention and use PCI-e #1 to supply power to only a single video card and pay attention to using "each" of the other leads coming from the power supply for "something" to balance the load. Yes, I know you all run around trying to hide the cables but you stick a knife in power supply engineering when you do not use all the cables if possible to power at least a 12V fan. Modular supplies make it too d*mn easy to leave out a cable entirely and thus unbalance the power supply load and keep the 12V rails from rising to their full power potential on some designs of power supply.

Thanks, and no I'm not new to overclocking. My first overclock was a Pentium II with a 440BX motherboard, I started tweaking this Pentium II when I was 8 and when I was 10 I got my first Abit BP6 with a Celly 466. I clocked the Celeron to 600MHz, a great achievement in that time. When I was 12 I saved pocketmoney to buy my brother's Pentium III 1GHz. It was a Compaq, but when I found the Crystal Oscilirator number I tweaked it anyway to 1282MHz! I got the parts for my current system (with a MSI RD480 Neo2 instead of the DFI I own now) 3 weeks ago. With that motherboard I got my X2 3800+ to 2,42GHz (unstable) and 2,23GHz (stable). I'm planning to clock it to 2,75GHz (Prime95 24h stable) with my new DFI.

That topic is only for DFI SLI motherboards? Or could I also connect a OCZ PowerStream 520W to my system?

 

@ RGone, thanks for the tip but those power supplies are not sold in the netherlands , here's a searchengine of the supplies which are sold in our country.

[centy]

They are available here for €120 (600w) €140 (700w)

""Sapphire Radeon X1900XTX"" is what is bringing power supplies to their knees with DFI boards.

This is a link into the FSP-group forums where they do not have all the BS that goes on in this forum. Some good solid technical details in this one thread from beginning to end and no bull shett just solid questions from one customer to their tech people. No wah wah my woo woo don't work type of threads there but take a good look as this is what is coming. Including a mighty good description of how that FSP Epsilon 700watt supply works across the rails.

 

A large majority of my close friends are already buying the 700watt Epsilon or waiting on the OCZ ones with very very similar specing and I am using Ocz's 700watt similar supply right this minute on CFX3200 with two X850s in SLi and the supply is running not walking or crawling with that load.
