Postal Dude Posted November 6, 2005 Posted November 6, 2005 I have just purchased a DFI LP UT SLI-D. It isnt in my system yet, its not even here yet! Jus reading up on a few things with PSU's and stuff. I have an Antec TruePower 430W (not version 2) Its not a native 24Pin PSU but it does have the extra 4 pin connector for independant CPU power. Ratings for each rail are as follows, +5v 36A, +12V 26A, +3.3V 28A. Im only going to be having one GFX card to start off with. And i'v got my eyes on a Noisetaker 600W when i bother to upgrade to SLI (more like can afford it ) Just wondering am i going to need to upgrade my PSU before i install anything. Im going to be getting a 7800GT and running 3200+ @2.5, soon to be a 146 @ whatever i can squeeze out of it. With an almost stock 7800GT, a winnie 3200+ @ 2.5, 1 HD, 2 Optical, 1 neon, 5 case fans (4x120mm(rad, 2 native case fans, 1 mouted over ram), 1x90mm). And a water cooler rated at 0.4A. Am i gonna be in trouble? Quote Share this post Link to post Share on other sites More sharing options...

tw33ter Posted November 6, 2005 Posted November 6, 2005 you are on your own when using a 20-pin power supply. DFI no longer will support customers who do not adhere to the minimum power supply requirements. if the board has a 24-pin power connector, then you must have a true 24-pin power supply. not a 20-to-24 pin adapter not a 5,000,323watt 20-pin with 80000 amps on the 12v rail a true 24-pin native power supply. period. there is no argument anymore on this subject. if the board has a 24-pin power connector, and we state (as we have) that you need a true 24-pin power supply and that a 20-to-24 pin adapter does not work and is not supported, then you need a true native 24-pin power supply. no arguments no trying to tell us we dont know what we are talking about. period you only have a 20-pin psu? a modded 20-pin psu? a 20-pin psu with a 24-pin adapter? you are not adhering to the minimim specs required by these boards to run. this means that any problems you have while not adhering to the minimum requirements will result in you being told 'you need a 24-pin native power supply of at least 480w' and that is the only answer you will receive on your problem until you meet the minimum requirements. sounds harsh? we don't tell you to put a 24-pin power supply in just to make you angry and see you complain about how you have to upgrade your power supply. we tell you that you are required to have a 24-pin 480w power supply because that is what is necessary. if you want to argue about it, by all means continue arguing about it. but you are not meeting minimum requirements and will not get any answer other than 'you MUST have a 24-pin native 480w power supply to run these motherboards and that is your problem so please upgrade to a minimum 480w 24-pin power supply' not much else to say on this subject. i'm tired of some of you who think you know more than our engineers continuing to argue that we have no clue what we are talking about and you can skirt the minimum requirements. follow the recommended guidelines. period.

fst h2o Posted November 6, 2005 Posted November 6, 2005 You "might" sneak by with what you have, but according to required spec's (here), you definitely should upgrade your PSU. If you have problems with the one you have, most likely the only answer you'll get is upgrade your PSU, so I'd do that to make sure that isn't a problem to begin with.

davidhammock200 Posted November 6, 2005 Posted November 6, 2005 The Antec TruePower 430W is a very good PSU & +12V@26A is fine for non-SLI, however we really can't live without a native 24-pin ATX, as doing so causes instability & has damaged mobos & RAM. If you want to stay with Antec the TruePower II 550W is SLI Certified & can be found for under $100, about the same price as the TP II 480W, the SP II 500 W is also invited to this party. However the OCZ PowerStream 520W is our #1 recommendation & is by far the most successful PSU for DFI N4 mobos. :nod: Pick from the "A" list for proven performance: http://www.dfi-street.com/forum/showthread.php?t=10854 Good Luck, Dave Quote Share this post Link to post Share on other sites More sharing options...
Postal Dude Posted November 6, 2005 Posted November 6, 2005 Ok. That answered me very clearly and by all means i will upgrade my PSU. Can someone tell me the difference between the 20 pin and the 24 pin? I jus thought it was the extra 4 pin cpu power intergrated into the atx connector. Which is why im slightly confused as to why DFI gave that big statement about a 24Pin must have. Anyone? Quote Share this post Link to post Share on other sites More sharing options...
phucker Posted November 6, 2005 Posted November 6, 2005 ya do not use a 20 - 24 pin adapter. i got lucky when i did it building my freinds new comp, all that happened was it fried my freinds newer antec 550 watt psu. i checked the pinout on the connector and it was right so there is just something the dfi boards do not like something about the adapter. just a word of caution.

Postal Dude Posted November 7, 2005 Posted November 7, 2005 Iv been looking at a few PSU's. On the DFI board, there is a 24Pin ATX connector AND a square 4 pin connector. Out of the ATX2 units iv been looking at. They have a 24Pin connector, but not the extra square molex. Anyone comment? Quote Share this post Link to post Share on other sites More sharing options...

All PSU's listed in the PSU guide have native 24-pin ATX & a p4 (4-pin, +12V) connector. In fact many have a EPS 8-pin (+12V) connector. Most native 24-pin ATX connectors are modular 20+4 pin connectors. Pick from "A" list & you have the Best of the Best, however if it is in the PSU Guide, it will work.

sthaznpride17 Posted November 7, 2005 Posted November 7, 2005 if you are REALLY confused just get the Antec Smartpower 2.0. It solved all my problems Quote Share this post Link to post Share on other sites More sharing options...
Postal Dude Posted November 7, 2005 Posted November 7, 2005 Im gonna go for the Tagan 580W Its based on a solid PSU, it claims to have better power. And is the same price Quote Share this post Link to post Share on other sites More sharing options...
