PSU's with adjustable voltage output on each rail

[Tex]

I know the PC power & Cooling ones have it on the good ones anyway. And of coure the True Control series from Antec do also but... what other PSU's have the ability to let you adjust the output on each rail?

PC and Power are the only ones with adjustable rails on ALL rails as far as i know. Antec only adjusts the 5 and 12V combined i think. At least on mine. I think Fortron Source has pots inside as well.

That's a great PSU with adjustable pots inside the psu. Dont bother about the look though. It's actually a good psu for a pretty cheap price.

funky did you see the amp rating on each rail? The rating on the 5volt line is huge. higher then I have ever seen.

Tex

I noticed that yes. Looks ghey though. 4 fans on a psu :O

I just read OP's review. Since its even on sale right now it sounds like a winner for 79 bucks. Thast 20 bucks cheaper then a true control 550. The one thing nice about the true control is modding the rails does not void your warranty in any way. Its a built in feature.

I really have no need for one tha big as long as it would hold the rails steady on my dualy's as it only has a cdrom or two to power also. The drives are in external cases with their own PSU's.

As far as i know, the True Control is peanuts compared to the Super Flower UNLESS they use the same hardware which i doubt.

Look for Fortron Source otherwise.

FANTASTIC psu's. Lasse can run his Vapochill on a 300W and the 12V never moves a damn notch. When using the 550W Enermax, the 12V drops to under 10.5 volts.

Typo?

$ .49? 49 cents for a Fortron Source 350 watt? LMAO!
You can run pelts from those.

I found both a 430 super flower on ebay for 43 bucks and some fortrons also. It ws like 60 bucks. Since I don't run a ton of fans and drives and crap I would think the 430 watt super flower would do ok for me. The 5 volt line is still really huge on the 430.

Damn 55 amps on the 5V rail IS huge.

mack if u look at shipping though it is 36$ :P

The TrueControl 550 is a great PS, Tex.

Mine powers my dual 2500 system without a hiccup, and that's got a hell of a lot of hardware in it:
MSI K7D-L
1GB DDR400/333 (1x 512 DDR400, 1x 512 DDR333)
Radeon 9700 Pro (8500 currently)
RocketRaid 1540
Audigy2 Platinum
5 port USB2 PCI card
4 160GB Maxtor DMax 9s
LiteOn 52/24/52
Toshiba 16x DVD
Zip250
Floppy
8 case fans
2 CPU fans
60x10mm fan on video card heatsink

BTW, the 3.3v, 5v, and 12v rails are all separately adjustable.

No way Bud. I just ran thru a checkout and UPS ground shipping was 5 bucks and change. Where are you? In the U.K. or something? Or what shipping method did you choose?

i was talking about the ebay link where the psu is $.49, but shipping is $36.

[Tex]

And geeky... what scares me right now on the Antec right now are the number of folks that have had them fail at 2cpu.com. And fail in the first few weeks or months.. Some have taken out whole systems... MB, HD's etc... when they were first plugged in.

I don't know....

Tex

[Tex]

I was going thru the directron link. But that PSU with 35 bucks shipping is also has no bids. You might get it for 5 or 10 bucks. If you look at the nice 500 watt fortron on ebay right now the shipping is 15 bucks for a 60 dollar psu. There are a*holes on ebay that make up for low bids with inflated shipping, You jsut got to be careful.

I dunno. I hadn't heard about that, but mine has been running my system for ~5 months, without a problem. Almost without a problem, anyhow. On the first one I had, the fan control circuit failed within 2 days of when I bought it. The replacement hasn't been a problem, though.

[madmat]

The only problem I've seen with the tru control series from a resaler stand point is people that don't have the first clue about electronics (but think they're experts) taking it home and cranking the rails all the way up and blowing out a motherboard or CPU and then crying that the parts were bad.
This is despite the fact that you can tell the trim pots were turned all the way up (but, but, I never hooked that part to the power supply...then why's it in the case?).
I'd recomend them to someone that knows how to monitor voltages with both hardware monitoring AND a good multimeter but I wouldn't recomend one to someone that is more of a plug and play kind of person.

[TheLostSwede]

The pots on those Antecs are to weak to blow out a mainboard. They only allow for up to 3% change i think which is way to weak for me at least. I need 5V at 5.3, 3.3V at 3.6 and 12V at 12.5. The Antecs just can't create those numbers without frying, not even the 400+ watters. A 300W Fortron or PC Power can do that without a hickup. There is the quality difference. Specs mean different to those companys.

[madmat]

I've never taken the tru control and cranked it up but I have dealt with the fallout from the situation I posed above.
It could have just been a fluke too.

[TheLostSwede]

Must have been madmat. First of all, you need to crank up those pots to minimum resistance just to get TO the steady lines. You then need twice as much to get OVER that numbers. It's junk for an overclocker. However, by breaking the warranty seal, you can tweak it more cause it has pots with higher values inside :/

[Geeky1]

Mackanz, I think you may have a dud PS. Mine has no problem hitting 12, 3.3, and 5v, even under full load, in my dually. And no, the pots are not all set at minimum resistance.

[TheLostSwede]

Actually my psu is all stock. Haven't touched it. With chipset voltage at 2.05, ram voltage at 3.05 and vcore at 1.97 my rails are 4.92 ,3.19, 11.88 with some fluctuations. That's not bad for a stock psu at all but this is the old Antec 412 which are way better than the newer ones. If i had the same voltage on a Truecontrol, the lines would be much worse and the adjustable pots isn't enough to cover up. That's what i meant.
