463686	2006-06-16 20:16:00	I have a HP Pavilion 7955 with a very small 200 watt power supply . My motherboard has a 4x AGP port that I'm currently using for my nVIDIA RIVA TNT2 model 64(hp) video card . I'd like to upgrade the card, can my computer support a Radeon 9550? I don't know what the power requirements are for that card . I also don't know if that card will work in a 4X AGP port . Can someone advise me on these questions?	burnselk (10567)

463688	2006-06-16 23:12:00	[QUOTE=drcspy]a 200watt psu is EXTREMELY minimal......and should be replaced.QUOTE] I agree drcspy.....but I need one with these exact diminsions: 5-7/8" wide 4" deep, 3-3/8" tall (including fan). I have looked and looked but have not been able to find a larger PSU. I can find the original replacement (200 watts) but nothing bigger. I have a small case. Some call it mini, some call it micro....but it's small. Any advice....besides build a new one? I've been thinking seriously about that.	burnselk (10567)

In theory (usually in practice) a motherboard with 4x AGP will support an 8x AGP grafix card. I recently upped my card from an MX440 (4x AGP, 64MB) to a Ti4200 (8x AGP, 128MB) which sits atop an MSI motherboard with AGP 4x. Works great :D The Radeon 9550 is a 8X/4X card which means it will work on either an 8x or 4x motherboard. You can pick up cheap/free second hand cases from all over (computer shops, TradeMe, if you have a friend with old comp stuff they havent dumped). Rebuild into that, this will allow a larger PSU	Myth (110)
463690	2006-06-17 00:10:00	yeh transfer it all to a new case that'll give you room for expanding anyway.....it's cheap enuf to do so.....	drcspy (146)
463691	2006-06-17 05:02:00	it may work fine with the existing PSU. it looks like that card is entry level so i'm picking its power draw will not be a lot. if it was me i would change the case a PSU, however just watch that it may not have a standard motherboard (ie not fit in a new case). does your pc use SDRAM ? if so its proberly going to run fairly slow anyway however that video card should be a good upgrade from a TNTM64, just don't exspect to play the high end games on it.	tweak'e (69)

Do I need to be concerned about the PSU voltages? I understand some of the computers like HP, Dell, Compaq, etc . have certain voltage requirements that some PSU's may not provide . For instance, I bought a 400 watt Antec PSU (with the intention of starting to buy parts for a new build) that will not work in my HP (Antec themselves told me this . . . . they said it doesn't have the - 3 or -5 voltages my HP require) . Can't remember exactly which . . . . . but it won't work . How do I determine what voltages a new PSU must have for my HP? I don't trust HP's tech support . . . . . too many different tech's have told me too many conflicting stories . Maybe I should go to someone who sells the original PSU that I have now and ask for an upgrade PSU that has those same voltages . A 200 watt Bestec 1956D PSU came installed my computer .	burnselk (10567)
463693	2006-06-17 09:22:00	Voltage is of no matter, 220~240VAC goes in, 12,5,3.3VDC all come out (I may have missed some) BUT what I am saying is that no matter the PSU the voltages are ALWAYS the same, it is the the power rating that you are interested in, you know you have a 200W PSU, I would reccomend a 350W ATX PSU minimum, you will have to look on the motherboard and see what connector is plugged into it from the PSU (Should be 20 pin) but it is best to double check :thumbs: EDIT: I have just done a little Googling on the PSU and here (affordablesurplus.com) are the specs of your current one. Also, it is the 20 pin ATX model, all you need to do is find an ATX PSU with a 20 pin connector, easy really :thumbs:	The_End_Of_Reality (334)
463694	2006-06-17 09:43:00	not that easy. i think they are a micro atx. atx psu's do not always fit in place of a micro atx. i had the same problem with a dell recently.	tweak'e (69)
463695	2006-06-17 17:05:00	Voltage is of no matter, 220~240VAC goes in, 12,5,3 . 3VDC all come out (I may have missed some) BUT what I am saying is that no matter the PSU the voltages are ALWAYS the same Not true, see specs below . Bestec 1956D Specs: OUTPUT MAX LOAD 200W AC INPUT 100-127V ~ / 7A 60Hz 200-240V ~ / 7A 50Hz DC OUTPUT +3 . 3V +5V +12V -5V -12V +5Vsb 16 . 7A 21A 10A 0 . 2A 0 . 5A 2A Antec SP400 Specs: OUTPUT +3 . 3V +5V +12V1 +12V2 +5V SB -12V Max . Load 22A* 21A* 10A* 15A 2 . 0A 0 . 3A Min . Load 0 . 5A 0 . 5A 1A 1A 0A 0A Load Reg . ±5% ±5% ±5% 5% ±5% ±5% Ripple V(p-p) 50mV 50mV 120mV 120mV 50mV 120mV * +5V, +12V1, 12V2 and +3 . 3V maximum output: 390 Watts max * +5V and +3 . 3V combined output: 130Watts As you see, the Antec SP400 doesn't have the -5V . And they said it wouldn't work in my HP . That's what the Antec rep . told me . . . . the Antec SP400 doesn't have the -5V that the HP needs . . . . and others may not either . So voltages do matter . But, I do appreciate the input, it's given me a whole new perspective on the situation . I'll go with a larger case . But, I'll be careful to check the voltages with the new PSU before I buy to make sure it will work on my current HP mobo .	burnselk (10567)
