Windows Forum / Windows XP / Hardware / July 2007PSU question...
Hi, I'm really out of date with hardware ! I'm about to cobble together an 865PE motherboard with a Pentium D925 on it, ...motherboard has a AGP slot so that I can use my old graphics card, ....Antec PSU I've been ogling has a 6 pin pci-e supply, does that just dangle unused (alright then "gets tied up":-) http://www.antec.com/uk/productDetails.php?ProdID=04644 In other words, will PSU be okay if that 6 pin power supply is unused, just like one can tie-up the 4 pin cpu power supply if not used on older boards/cpu's that don't need it 4pin power. regards, Richard Yes, it's there in case you need it. With a PSU it's always better to have more than less. > Hi, I'm really out of date with hardware ! > [quoted text clipped - 9 lines] > > regards, Richard Thanks Barry, much appreciated. regards, Richard > Yes, it's there in case you need it.

I do use an Antec, just not that model. AGP 4X is slowest AGP it will do. Slower AGP won't work on mine. Dual core Pentiums won't work with that chipset. If I didn't know any better, I'd think the whole post is a ruse. Don't bother replying, I won't believe a word you're saying. Dave ...cough! I don't know why you think my post is a "ruse," ....suspect you don't know what you're talking about, and I hope you're wrong ! ....I've already ordered motherboard and Pentium D925 cpu. Motherboard specs. say that it supports Pentium D's ! ...and quadcore Kentsfield's !!! It was just that I got fed up trawling through psu information and, whilst I knew that, (for most psu's), the 4 pin cpu connecter doesn't have to be under load, I couldn't pin down any information about 6 pin pci-e connecters. I suspected that they don't have to under load but, wanted to be sure. regards, Richard >> Hi, I'm really out of date with hardware ! >> [quoted text clipped - 20 lines] > bother replying, I won't believe a word you're saying. > Dave ...AND the vendor sent me a P935, perhaps they had run out of P925's, so they "upgraded" my order for free. I had my heart set on the 2x3ghz cpu, and had ended up with a 2x3.2ghz cpu, ...perhaps I should be pleased ! ...and the peculiar thing is that, whilst quite responsive - and dual channel / memory bank / page interleave is working - the thing doesn't seem all that much faster than my old XP2600 Barton on a PcChips M848A "non" dual channel board ! regards, Richard > ...cough!

Have trawled through site after site, tried several different "wattage calculators" that give wildly different figures, seemingly because they want you to click on a "buy a psu here" link !! Anyhooo! ...can someone give me a more accurate idea for watts, for ordinary desktop midi-tower innards as follows. (I know that if one goes too "cheap" one could end up with a 250watt psu badged as a 500watt etc. so I'll probably buy and ANTEC.), ...and I most likely will want to add an IDE pci card and another IDE hd, at a later date.

[quoted text clipped - 33 lines] >> >> Richard Richard: Don't get too caught up in this wattage business. You've got a relatively modest system (even if & when you'll need "extra capacity") so I would think a 400W+ PSU from one of the usually reliable sources, e.g., Antec, Enermax, Fortron, Seasonic, etc., should serve you well. Your cost should be well under $100. Why don't you simply access Newegg's site and see their offerings together with user comments? And there are a slew of websites that devote themselves entirely or partly to reporting & testing power supplies. BTW, you don't mention your current PSU. Is there some problem with your current unit or you have some suspicion that it's not functioning properly?

Daren't upset it ! ...so for lots of obvous reasons, I'll spsend the extra money and eventually build a whole new one, get it installed, and iron out any problems, and after several months hoping to duplicate my XP Home and apps. platform, I could then move to it :-) ...Tweaking up XP is the hard / long winded part ! Have been reading newegg and Tomshardware PSU reviews (Fortron/Seasonic :-), and lots of others. After lots of reading wildly differing opinions, I was beginning to suspect that something around 400 quality watts would do, then there's the consideration that even quite high quality psu's perform more stably at their "middle" loading range. I've been eyeing up the Seasonics at my favourite hardware vendor :-) ....thanks again, regards, Richard > Richard: > Don't get too caught up in this wattage business. You've got a relatively [quoted text clipped - 56 lines] >>> >>> regards, Richard It depends on the specifics of your system configuration and intended usage. Upgrading the video card has typically been the biggest consideration in PSU power requirements. At one point in the recent past video card power requirements jumped from the <20watt range up to potentially over 60watts for some high end models. Video cards without a secondary power connector can't draw more than the bus limitation, something around 40watts IIRC. My P4 Media Center (Radeon x600 PCIe video) came with a 350watt PSU. Internally it is still the stock configuration (1Gig Ram, 300Gig SATA, DVD burner and DVDrom yada yada) With a USB wireless adapter added and external USB harddrive running the idle load on the UPS is less than 170Watts. Without the external drive or monitor running, the idle load from just the computer, wireless KB-Mouse, IR controller and USB WiFi is only between 112 and 125 watts. Turning on the webcam bumps that up another 20 watts or so. Even with a second external drive connected I haven't had the system do anything that ever drove the average power load above 250 watts for more than a few moments. > Thanks Anna, > [quoted text clipped - 85 lines] >>>> >>>> regards, Richard Arrgh! 8 day old thread. > It depends on the specifics of your system configuration and intended > usage.
