Guest area51 Posted July 30, 2006 Posted July 30, 2006 Hello, While waiting for my new OCZ to show up I decided to throw my wife's Hipro 400W in my system out of curiosity. I was looking for something, anything, to power my new stuff up to see if it was all good. Freakishly enough this thing has BULLETPROOF rails even under a load that should traumatize it. I am running it right now and it easily is running a system that "should" be seriously problematic for it. Gaming, prime, OCCT whatever...these rails do not budge. They are far more stable than my last 520 Modstream or Antec True Power 550. Who knows how long it would last though lol...probably blow up and set my stuff on fire haha. I will not keep it any longer than it takes for my new OCZ to show up and am not endorsing it (dont know squat about hipro) just wanted to share my experiences.

ReelFiles Posted July 31, 2006 Posted July 31, 2006 I wonder how their high end models do, if that 400W unit is solid. It might be worth checking into, since my wife needs a new PSU badly. She's not running anything crazy, but the MCE 600W unit, she's using now, is just all over the place. The PSU was great for about 6 months now it's rails are just bouncing back and forth even under small loads. Maybe that's what will happen to that PSU, after some time. I'm gonna read up on some their products and let ya know if I find anything interesting. Edit: Went to their site and saw that their highest rated PSU is 400W, nevermind, might be good enough for wifeys Biostar 6100.

red930 Posted July 31, 2006 Posted July 31, 2006 The closer a unit comes to it's maximum output, the steadier the rails become. Think of it as a car engine. Dumping the clutch at idle will stall the engine. Dumping the clutch at 3000rpm will launch the vehicle. This is one reason you don't want to buy too much more PSU than you need or get a high power unit with better regulation on the rails. That 400W PSU is probably right at its limit which isn't good for longevity. Quote Share this post Link to post Share on other sites More sharing options...
Guest area51 Posted July 31, 2006 Posted July 31, 2006 @ex roadie Did not know that about rail stability and load...thanks for the info. @ reelfiles If you go to newegg they have 400, 500, and 600w units... The manufacturer's site looks fishy and I would not trust them to anything I really cared about but they seem well manufactured and the one I am using as a temp is hanging in there like a champion for now. I would definetly buy another for the wifes email machine though... Quote Share this post Link to post Share on other sites More sharing options...
ReelFiles Posted July 31, 2006 Posted July 31, 2006 That's what I am thinking, perfect for the wife, no OC, onboard sound, onboard video (for now), and the most intense game she plays is Sims2, LOL. This one seems good enough for her, and it's $37, but out of stock for now. http://www.newegg.com/Product/Product.asp?...N82E16817174023 Brand HIPRO Model HP-P500W/TOP-500P5 SPEC Type ATX V2.01 Maximum Power 500W Fans 1 Main Connector 20+4-Pin Dual +12V Yes SLI Support No Modular Cabling Support No Input Voltage 115/230 V Input Frequency Range 50/60Hz Input Current 10A @ 115V, 6A @ 230V Output +3.3@28A, +5V@44A, +12V1@20A, +12V2@20A, [email protected], [email protected],[email protected] Quote Share this post Link to post Share on other sites More sharing options...
Angry_Games Posted July 31, 2006 Posted July 31, 2006 I've got this Aspire psu that claims 420w, and more importantly 30A on the 12v rail yet an Infinity RS482, stock speed Opteron 146, and X850XT PE stock speed = measured with a multimeter, the 12v rail is already down to 11.58v the instant you turn on a 3d app (again, all stock speeds), the psu's 12v rail drops all the way down to 10.75v, give or take .1v either way The problem is that these psu mfg's end up with such 'great' rails because they are testing them at temperatures that just aren't realistic...like 12v @ 30A with temps at 25C etc which is just insane because you'd have be outside in a polar region or in a super A/C'd lab to even think a psu could maintain 25C temps under load usually when the temps reach realistic thresholds like 40C to 55C, the rail rating plummets all the way down to less than 50% efficiency, and a realistic rating of something awful like 12A @ 45C etc personally...I'd rather buy a $50 or $60 FSP/Enermax 400w lower-end psu for the wife and her limited needs and know the psu will never be the problem instead of opting for the cheap $37 no-name (or unknown) brand of 500w psu etc Thats just me and ExRoadie though...I like to save dollars like the next guy (considering that I am usually a lot poorer than the next guy that shows up here), but I just won't compromise on certain things like psu's.

ReelFiles Posted July 31, 2006 Posted July 31, 2006 Makes sense. After reading some of your posts, I can see we are in similar financial situations, and I can definitely appreciate your opinions on "good" deals. ...the psu's 12v rail drops all the way down to 10.75v.. That's just nuts. Her 600W MCE isn't that bad, but it's 12v rail is about as steady as a Mexican jumping bean. I definitely have to get her something new, before I throw that POS mobo of hers out of the damn window. I was checking out the RS482, and it looks like a great deal, for her needs and beyond.

ReelFiles Posted August 4, 2006 Posted August 4, 2006 When I questioned someone about ExRoadie's statement, I got this as a response from jonnyGURU himself: ...I have no issue with the main ATX and ATX12V/EPS+12V cable being fixed. That was NOT my argument. I was pointing out that the two cables were two completely separate cables. Not that they were not modular. I could not see the point of having one cable for 4-pin and one cable for 8-pin. People at Corsair told me it was for certain 4-way/8-way boards (even one Tyan dual Xeon board) that require BOTH one 4-pin and one 8-pin on the motherboard. I stuck to my guns and fired back with "wrong customer." Someone looking for an EPS solution for an EPS board is not going to use a tri-rail, SLI, modular power supply... Not trying to start a cross-forum war here, just figured you might like to know, what he said. Quote Share this post Link to post Share on other sites More sharing options...

red930 Posted August 4, 2006 Posted August 4, 2006 Thank you for the information yet the application presented is entirely out of place to this forum as DFI does not make dual-processor boards. At least in their main lineup. Quote Share this post Link to post Share on other sites More sharing options...
